INTRODUCTION
1.1.
Purpose
1.
This CCTV Development Standard describes general requirements which apply to most
fixed CCTV projects. It is intended to be read in conjunction with site or project specific
documents such as specifications and drawings that will state the scope and quantities,
design options to be adopted (if applicable) and indicate any departures required as a
result of the project specific design.
1.2.
1.
Exclusions
This document does not cover mobile (or “on-board”) CCTV systems installed on trains,
trams or buses.
1.3.
National Code of Practice for CCTV Systems
The DOT Victoria is a participant in the maintenance of the “National Code of Practice for
CCTV Systems for the Mass Passenger Transport Sector for Counter-Terrorism" (NCP).
The statutory authority Public Transport Victoria (PTV), formed in April 2012, assumed
responsibility for day-to-day management of Public Transport infrastructure in Victoria,
and now provides technical and operational input to the development of the National Code
of Practice.
2. Achievement of conformance with the NCP as part of all station upgrades underpins
DOT’s objectives as stated in this Development Standard.
3. The NCP contains three Priority levels, with Priority 1 being the highest priority and most
extensive in terms of CCTV facilities scope.
4. The scope of facilities and functional performance of all new CCTV works shall achieve
NCP compliance, wherever practicable, within the works area and facilitate achievement
of future compliance across the whole site. PTV will make an electronic copy of the NCP
available to consultants and contractors engaged to undertake CCTV works as part of
PTV sponsored projects free of charge.
1.
1.4.
Station Classification and PTV Coverage Levels
This CCTV Development Standard is based on both (i) the achievement of both NCP
compliance, and (ii) other security/operational/safety/crime prevention objectives.
2. PTV has defined a number of station classifications for CCTV termed “Levels” which
incorporate NCP, other security factors, and operational requirements, in their definition.
The top level with the most extensive facilities provision is Level 1. Refer to Annex 1.
3. PTV has defined more levels than the NCP due to differing increments in operational and
NCP requirements. It is possible that PTV may choose to classify a station at a certain
Level in view of funding limitations, with a view to upgrading the station to a higher Level
in the future.

The PTV Transport ICT Infrastructure team (CCTV Team will specify the Level applicable
to each project and station.
5. The PTV Levels use the same definitions for grades of coverage (Identify, Recognize,
Detect, Monitor [was "Observe"]) as the NCP and Australian Standards referenced
therein.
4.
1.5.
PTV Transport ICT Infrastructure Team Consultation
PTV retains the design authority on all CCTV projects and shall be directly involved in all
scope change decisions and technical information exchanges throughout the project
lifecycle.
2. Consultation on camera placement, coverage objectives and equipment accommodation
shall be undertaken by the Designer (as defined in clause 1.11.1c) prior to the
commencement of civil, structural and architectural design to:
a. Allow the services infrastructure and building, intermodal and car park layouts to
take CCTV fields of view and cable distribution into account when considering civil,
structural, layout and landscaping options.
b. Ensure that appropriate space and environmental control allowance is made for
site head end equipment accommodation including access clearances, as defined
in VRIOGS 013.1 “Communications Equipment Room Brief”.
c. Ensure that needs for mounting structures, accessible cable pathways and
locations for Field LAN equipment are taken into account when considering
architectural, civil and structural options.
3. Liaison with PTV’s Transport ICT Infrastructure team (CCTV team) regarding delivery of
the CCTV system shall be instigated by:
a. the Designer (as defined in clause 1.11.1c) regarding operational requirements,
PTV Level classification, archival capacity, distribution method, interfaces to other
systems, camera coverage plan and review / approval of specifications and
drawings.
b. the Contractor (as defined in clause 1.11.1a) regarding review of product specific
designs and shop drawings; camera field of view confirmation; CCTV network
interfaces (IP addressing, time synchronisation, firewall settings); transition plan
and operator access profiles; operational outcomes plan, system commissioning
plans, acceptance test plans, training plans, maintenance support and as-built
documentation review.
1.
1.6.
PTV Digital CCTV System Compatibility
The PTV has established a single, integrated, IP-based digital CCTV system on the
Melbourne metropolitan rail network with an IP "Security Network" point of presence and
CCTV head end equipment at every station and stabling yard. All recording and viewing
is via IP servers and computer workstations, with legacy cameras installed prior to 2006
converted to digital format using site head end encoders. (Regional stations are gradually
being connected as station project opportunities and VicTrack network expansion permit).
2. Any new CCTV facilities provided for the upgrade of Melbourne metropolitan railway
stations and associated modal interchanges shall be planned as a fully digital (IP camera)
expansion of the existing digital CCTV system at the respective station.

New metropolitan or regional stations CCTV systems shall comprise a fully IP camera
based system conforming to the PTV Standard Operating Environment without any
analogue cameras (with the possible exception of some specialist applications like lifts
and covert cameras). As a standard, every station site will still have at least one audio
capable encoder for phone/lift audio and alarm interfacing.
4. The key aspects of the provided digital CCTV facilities are as follows:
a. Only the control room recording equipment and remote monitoring equipment are
exclusively digital at all sites. Analogue cameras and cabling back to the control
room that existed prior to 2009 have been retained and will require replacement
and augmentation as part of any station upgrades where the camera sight lines or
locations are affected by the upgrade works.
b. A metropolitan wide optical fibre network and IP "Security Network" has been
extended to all stations to facilitate time synchronisation, remote archiving and
remote access and downloading of images. The network is described in a PTV
“CCTV Metropolitan Network Design” document and provides a minimum of
Gigabit Ethernet connectivity to all stations. The network is partitioned into several
VLANs to serve as a backbone for electronic security/access control systems and
passenger information systems.
c. CHPs (emergency "red button" intercoms) are interfaced via telephone recording
adaptors to head end audio capable encoders to achieve audio recording of
emergency calls. Digital CCTV viewing workstations are provided at line control
stations to allow the operator to view any camera at any line control station and to
monitor emergency call cameras.
d. Selected staff from Victoria Police, Emergency Services, the ARO, DOT and PTV
have the ability to live view any cameras anywhere on the network in Melbourne
at their workstations. ARO and DOT CCTV analysts have on-line access to all
recorded images from any camera at any metropolitan site and selected regional
stations.
e. Archival functions are based on standard server and storage products and
centralised to a limited number of “Digital Recording System” sites selected on the
basis of suitable location within the network, and available space.
i. Parallel archiving of selected cameras occurs at designated line control
group archival sites.
ii. Archival storage may be provided as a managed service by VicTrack, or
by ARO maintained storage servers.
iii. Additional cameras at any one site will require funding of incremental
upgrades to storage capacity at other sites.
f. The Digital CCTV System is based on a common software and hardware platform
across all sites including DVTel Latitude NVMS software capable of supporting
H.264 operation; DVTel MPEG-4 or H.264 encoders, decoders, DVTel (or PTV
approved compatible IP cameras); specific Allied Telesyn site switches and
selected POE industrial LAN switches and POE+ injectors. Subject to ongoing
product availability and PTV “Approved Equipment List” updates, all extensions
and upgrades to the system shall be based on the same products to facilitate fault
diagnostics and rationalise training, spares and documentation. Note that
introduction of new products can only be allowed through execution of an
Engineering Change Notice process with the respective ARO.

g. The CCTV equipment installed at the time of replacement of analogue recording
equipment was constructed to standard rack layouts and wiring harness plans.
The racks were fully pre-wired for the maximum analogue camera count they could
accept, but were only populated with equipment to support the equipped cameras.
Spare space for fibre connections and 48V DC power supplies to LAN switches
around the station were left available for station upgrades using the specified IP
CCTV.
h. The physical infrastructure, IP network, Latitude software and operating system is
subject to a comprehensive security plan which must be maintained through all
adds, moves and changes. PTV will advise settings.
i. A network management system at VicTrack monitors and initiates responses to
alarms 24×7 from all managed devices on the CCTV network. Parallel monitoring
during business hours and event history access is available to ARO maintainers
for fault response diagnosis.
j. The long term strategy is to migrate all existing analogue cameras to IP as they
reach end of life, or as they are replaced in the process of station upgrades, and
to phase out the respective camera drive units and non-audio encoders.
5. This document specifies the requirements for new infrastructure to maintain full
interoperability with the existing CCTV system and compatibility with the long-term PTV
CCTV strategy.
1.7.
1.
CCTV Evidence Management Procedures
Government agencies, transport operators and related support organisations are required
to adhere to a set of evidence management protocols and procedures governing the
access to and processing of Closed Circuit Television (CCTV) data, including the
documentation of a verifiable chain of custody for all CCTV evidence from the point of
recording. The protocols and procedures for the Management of CCTV Evidence Records
are authorised and administered by the Senior Manager, Transport Insurance & Risk
Management Services, Department of Transport.
1.8.
1.
CCTV Functions
In meeting the agreed PTV objectives, CCTV systems may, in addition to recording
images of a scene under surveillance, be required to perform, or assist DOT, PTV or ARO
staff or Victoria Police members to perform, one or more of the following functions:
a. record Customer Help Point “red button” and lift car phone emergency calls;
b. provide notification that an incident is occurring;
c. confirm that an incident has occurred;
d. estimate passenger load numbers (e.g. at platforms);
e. identify individuals involved in an incident;
f. identify vehicles involved in an incident;
g. measure the location, speed and/or relative positions of vehicles involved in an
incident;
h. record the sequence of events surrounding an incident;
i. record the location of pedestrians involved in an incident; or

CCTV New Station Scope Summary
The New Station works shall comprise the physical provision of a complete new CCTV
infrastructure including all relevant items from the following list, as indicated in project
specific documents:
a. 45RU CCTV equipment rack cabinet connected to power outlets and earthing.
b. UPS with 2-hour battery reserve and integral Environmental Monitoring probe. If
the local power supply utility advises a longer duration for the 90 percentile power
outage at the station location, the UPS battery storage capacity shall be increased
such that the battery run time is long enough to support continuous equipment
operation through 90% of power outages.
c. 1+1 redundant 48Vdc 31A power supply with integral distribution in the CCTV rack.
d. System server to execute all NVMS system, alarm and directory database
functions for a standalone implementation, together with 30 days of attached
storage.
e. Provision of a local workstation for system administration and access/retrieval of
recorded images. This workstation may double as a local viewing facility at
manned stations.
f. Site fibre patch panel in the CCTV rack.
g. Site LAN switch in the CCTV rack.
h. Field LAN switch enclosures and associated industrial LAN switches, 12V DC
power converters and cable termination equipment around the site to serve as
camera network connection or "concentration" points. The station design should
minimise the requirement for outdoor enclosures through architectural
coordination.
i. IP cameras and housings to achieve the specified coverage with Cat6 cables to
Field LAN Switch locations.
j. Camera mounting brackets and poles as applicable.
k. OM3 multimode multi-strand fibre signal path and 10mm² 48V DC power feed to
Field LAN switch locations.
l. Cable pathways such as ducts, underground pit and pipe, steel conduit under
structures and the like to run cables.
m. Patch cords, fly leads and fibre interfaces to interconnect all equipment.
n. Tamper and fault alarm notification system. This may be by providing hard wired
alarm outputs or high level (software LAN) interface, and rack door switches, to
the site security alarm panel and configuring sectors for 24 hour alarm reporting
of CCTV alarms to a monitoring centre, together with definition of response
actions, and/or a system to notify the maintainer of system events and faults via
3G or dial modem to SMS, email or recorded voice announcement alert.
o. Labelling of all fixed and patch cables, provision of equipment ID labels next to
frames and Line Replaceable Units (LRUs) on equipment racks adjacent to rack
rails and fixing of bar codes to LRUs and spares.
p. Warranty period first-in fault response, service restoration and replacement of
defective items.
2. The CCTV works shall also include provision of the following plans and documentation:
a. Operational Outcomes Plan
b. Camera Coverage Plan (“for construction” version only unless the project is D&C)
c. Shop Drawings
d. Cable Test Plan
e. System Commissioning Plan

STABLING YARD AND DEPOT REQUIREMENTS
6.1.
General Requirements
Stabling yards and rail car maintenance depots generally use the same products and
have the same scope of services and responsibility matrix as a manned station if it was
located in the same area, as described in Clauses 3 and 5 respectively.
2. A stabling yard will usually be a separate site on the CCTV network, with its own CER
(“Control Room”), CCTV rack with PIM router, and VT Security Network connection
independent of adjacent or nearby stations.
3. The following items required for stations are not part of stabling yard scope:
a. CHP interfacing, LIUs, recording of emergency phones or lift car phones, or audio
interfacing in general.
b. Lift alarm connections, lift SNMP Alarm Interface Units or diode communing banks
to split lift alarm signals between encoders and SNMP interfaces.
c. Analogue cameras.
4. The following additional infrastructure requirements may apply at stabling yards which
are not normally encountered at station sites:
a. The distances of field LAN switches from the CER are often over 250 m. The
optical fibre distribution may need to be designed and configured as a physical
loop around the site to achieve a loop architecture for the site distribution network
whilst staying within distance limits for 1000baseSx transceivers.
i. In such instances, 48Vdc ELV cabling to Field LAN Switches will still be
star wired from the CER.
ii. It is advantageous to construct a physical fibre loop toward the yard
perimeter, as this assists with the possible later installation of perimeter
penetration detection sensors on the surrounding fence.
b. The site may be too large to allow field LAN switches to be remotely powered by
48Vdc from a single CER 48V supply via standard 10mm² conductor cable without
exceeding the nominal design voltage drop allowance of 6Vdc.
i. In such cases, the site should be broken up into zones of approximately
250m radius and a battery backed 48Vdc supply provided within a suitably
located building, normally co-located with a rack mounted Field LAN
Switch.
c. Access control is usually provided to yard vehicular gates (which may be motor
actuated sliding/swing gates, or boom gates) and pedestrian gates. These gates
will usually be fitted with intercoms (as part of CCTV scope) to allow non-cardholding visitors to request access.
i. These gates are usually monitored by CCTV cameras and the intercoms
interact with CCTV system spot monitors at the intercom answering point
(usually a security guard desk or the line control station desk) to display
the calling party for identification.
ii. The intercoms are PoE VoIP terminal devices wired to CCTV Field LAN
Switch ports in the same way as IP cameras. An intercom system server
unit connects to the site switch and is located in the CCTV rack.
iii. PTV and ARO product approvals apply to intercoms.

6.2.
iv. Gate controls will normally be controlled by an access control “door
controller” panel in the vicinity. Such panels may be integrated with Field
LAN Switch enclosures and powered (via local DC-DC converters) from
the 48Vdc supply.
Conduit routes generally in the area considered the track reserve (which may be
the whole yard) have a deeper depth of cover than stations. Additionally, there are
likely to be multiple track crossings and a need to design some pit and pipe routes
for 1200 below top of rail depth (approximately 900mm depth of cover after taking
rail height and ballast depth into account).
Rail yards may house traction supply substations, or act as a CCTV PIM routing
node (or “site switch”) for traction supply substations outside the yard.
i. Substations outside the yard will normally be connected by VT SMOF lines
to the CCTV rack.
Cameras may also be mounted on gantries and other structures within the yard
(as opposed to primarily canopies and poles on stations).
VRIOGS012.2 applies to communications infrastructure within rail yards.
Rail yard CER’s are sometimes a preferred location for archival facilities. A second
CCTV rack may be necessary to accommodate archivers where applicable.
Operational Requirements
Specific consultation with the proposed operators of the facility must take place to fully
comprehend the movement of people, vehicles and trains within the facility, and the
impact these will have on CCTV camera placement and viewing.
2. Lighting levels are often lower than stations and lighting must be coordinated to ensure
sufficient illumination for night time camera operation is achieved, or that supplementary
infra-red illumination is provided.
3. The following general operational requirements usually apply:
a. Camera coverage of the perimeter fence is required (by the NCP). Better than
90% of the fence should be covered at the specified grade.
b. Camera poles must not be placed so close to the fence that cameras on them
could be easily reached by climbing a ladder from outside the fence or climbing
onto a vehicle roof.
c. Walkways between train stabling roads and around the site (including around and
between buildings) should be within camera coverage. This is both an operational
safety requirement for drivers and maintainers as well as a security requirement
to monitor activity in the event of successful fence penetration.
d. Several PTZ cameras should be provided to allow train movements to be
monitored through the site and to allow zoom in to investigate any alarm reports
or emergency incidents more closely.
e. One higher level PTZ (at height of 10m or more) should be provided around the
centre of the stabling road area to allow some ability to zoom in to incidents from
a perspective other than the end of each road.
f. PTZ cameras should be provided at track gates to provide recognition grade
coverage of the gate itself, but also to look down the track towards approaching
or departing trains.
g. Cameras are required at vehicular and pedestrian gates (usually both inside and
outside) to meet NCP, to monitor staff movements and identify visitors using
intercoms to request site entry.
h. Substations or major power infrastructure requires camera surveillance (NCP).

Staff and visitor car parks are covered by cameras (as for stations).
If the site has staff administration buildings or driver rooms, the building entrances
are covered by cameras.
k. Camera maintenance access must be considered in the context of items restricting
vehicle movements including tracks, traction supplies and signal infrastructure.
l. Any on site intercom answering points will require a split screen CCTV monitor
displaying views of all gates controlled from that point.
m. Cameras monitoring train control and incidents as per c, d, and e above will usually
be exclusively monitored and controlled by the CCTV workstation at the respective
train control desk (usually at the line control station, but possibly on site).
n. A fully functional CCTV workstation is usually only provided if a security guard
desk is also provided in an administration building on site. Any such workstation
would normally have its own UPS if in a different building from the CER.
4. In the future, spare fibre pairs may be required to support an additional “On board CCTV
download” IP network connecting Wi-Fi access points around the site.

coverage. The following section details the provision of associated backbone and final
camera distribution cabling.
2. Its intended audience is the “Designer” (as defined in clause 1.11.1c) of camera coverage
and placement, and the associated network, cabling and pathways for the respective
project. Its emphasis is particularly on the Reference Design (issued with tender call).
Depending on the project delivery the Designer could be:
a. PTV Systems and Information Services Division staff
b. A station upgrade or new station design Consulting Engineer engaged by PTV to
prepare detailed Tender documentation
c. A specialist resource engaged or employed by the Contractor on a project
delivered on a turnkey “Design and Construct” basis

Preliminary Operational Outcomes Plan Input
Camera operational requirements (for producing coverage plans) shall be part of the
Preliminary Operational Outcomes Plan (clause 8.2.1) produced prior to executing
detailed design.
7.3.
Camera Placement Criteria
The Designer shall be responsible for producing camera coverage plans for approval of
PTV, based on compliance with the respective coverage level indicated in Annex 1. An
appropriately scaled plan of the site shall be used to show composite camera coverage
for the entire site. The camera coverage plans shall clearly show the intended field of view
for each camera, shaded in a colour that shows the designed grade of coverage, e.g.,
identify, recognize, etc.
2. Generally the placement of cameras shall aim to achieve a minimum proportion of
coverage of each area identified in the respective PTV Level definition table as follows:
a. At least 70% of each area shall comply with the respective grade.
b. At least 85% of each area shall comply with the respective grade or the next grade
lower.
c. At least 90% of the platform length within 1.0 m of the platform edge shall comply
with the respective grade or the next grade lower.
d. Any point within 1.0 m of the platform edge on the entire “patron-accessible” length
of any platform shall be within the field of view of at least one camera.
e. At least 70% of choke point width shall comply with the respective grade.
f. At least 90% of choke point width shall comply with the respective grade or the
next grade lower.

For example, on a PTV Level 1 station 165m platform (within 1m of the edge) nominally
requiring Recognition grade coverage, at least 115m (70%) of the coverage shall be
Recognition grade or better, 149m (90%) shall achieve Detect or Recognize (with no more than
34m of Detect grade), and all 165m shall be within the field of view of one or more cameras
(any grade to below Monitor).

Coverage shall include objects in the following vertical range relative to finished ground
or floor level:
a. Monitor, Detect and Recognize grades: From 0 mm to 2000 mm above. For
sloping ground levels (such as ramps) the vertical field of view shall be maintained
along the sloping surface by virtue of camera down-tilt or up-tilt.
b. Identify Grade: From 750 mm to 2000 mm above.
Areas within the plan view of the camera but outside or under the vertical coverage
described in 7.3.3 shall NOT be shown as being covered (by virtue of shading) on
coverage plans.
a. The ANNEX 2: Camera Field of View Range Calculator may be used to calculate
the coverage for flat ground.
b. For sloping ground the field of view shall be modelled in elevation using CAD, a
more complex Excel model, or CCTV modelling software with sloping ground
capability.
Cameras shall be positioned for ease of maintenance access and freedom from
accidental damage by other trades. Locations which are above drains, or near items of
plant which preclude safe access shall be avoided. (refer also to clauses 1.1, 1.1).
Camera locations and zoom setting shall be chosen to optimise the coverage area at a
particular grade by positioning to avoid occlusions from nearby suspended signs,
speakers or temporary banner hanging points and to see under areas with roof cover.
To ensure capture of any camera theft or tampering actions, all fixed cameras shall (as
far as practical) be located within the field of view of another fixed camera or un-occluded
pan/tilt/zoom range of a PTZ camera.
Cameras shall be positioned to avoid backlight and pointing into the sun at particular
seasons and times of day, especially early morning and late afternoon.
Even if identification coverage is not required under the respective PTV Level,
consideration shall be given to strategically positioning some cameras to capture at least
one facial image (preferably of recognition or better grade) of each person passing
through a site (for example as patrons pass close to an “monitor” camera).
Cameras shall not be mounted within the Structural Gauge Envelope (track safety
clearance zone) as defined in the document VRIOGS 0001-2005. Cameras which must
(in order to achieve the required field of view or camera angle) unavoidably be mounted
within 500 mm of the edge of the clearance zone, or above locations which are precluded
from ladder or scissor lift access, shall be provided with a swinging arm bracket fitted with
a secure locking device that enables the camera to be swung into a safe working zone
and accessed for maintenance purposes. (Refer also to clause).
Choke point cameras shall be mounted at a height and angle which allows front-on face
views of people entering the choke point (as opposed to side-on views or tops of heads).
This requires the horizontal and vertical angle of the camera with respect to the target
object and direction of travel to be less than 15°. Generally the focal point and field of view
shall be optimised to the location where persons passing through the choke point are
likely to look towards the camera. For persons this is typically just after passing through
a ticket gate, just after stepping off at the base of a stair, or several metres back from the
ends of an escalator.

Cameras covering the entry/exit points of car parks shall be mounted at a height and
angle that allows a front on view of the vehicle’s number plate. This requires the horizontal
and vertical angle of the camera with respect to the vehicle and direction of travel to be
less than 30°. The intended field of view shall ideally allow identification of the vehicle’s
number plate.
13. Cameras shall be mounted at the following heights according to installation location (refer
also to clause 8.26.1 to 8.26.4):
a. Platforms and built or covered station areas which are not scissor lift accessible
(ladder access only): Flush with a suspended ceiling up to a ceiling height of 3.3
m, on a bracket attached to roof, wall or building structure at 3.5m to the lowest
point of the camera housing.
b. On platform poles more than 2.5 metres from the platform edge: Height 3.5 m to
the lowest point of the camera housing.
c. In station areas having scissor lift access: Height to bottom of housing of 3.5 m to
6 m, height to be consistent with target field of view objectives.
d. In open air car parks and stabling yards on poles: Height to the bottom of the
housing shall be nominally 4 m. Locations which cannot be accessed by scissor
lift or cherry picker shall be avoided in the process of determining pole placement.
If scissor lift or cherry picker access cannot be provided, poles meeting regulatory
strength requirements and fitted with fall arrestor and ladder attachment brackets
shall be provided.
14. Where possible within the structural/architectural constraints the angle of the camera
above patron faces shall not exceed 15° above horizontal to ensure that “face on” images
are captured through the coverage area. This is of greatest importance for identify and
number plate recognition cameras.
a. The “recommended” column of the table below indicates the minimum IDENTIFY
camera distance from the target to achieve a down tilt angle of less than 15°.
b. The “closest” column of the table below indicates the worst case compromise
IDENTIFY camera distance from the target to achieve a relaxed down tilt angle of
less than 25°. The compromise is typically only accepted where the target choke
point is at a fixed range (such as a lift door or lift car) and the target camera
distance is constrained by a solid tunnel/overpass/corridor or lift car wall.
c. Where the Cameras mounted at any specific height above floor level (or the level
of patron feet where the target is on an escalator or stair) shall be positioned at
the following minimum distances from the start of closest coverage (and zoomed
in as required):

Cameras shall not be mounted on third party light poles unless prior agreement has been
reached with the third party or the requirement is indicated in project specific documents.
16. Cameras shall be positioned with respect to light poles and light fittings so that the lights
are not within the camera close-in field of view (thereby causing either glare in the camera
scene or auto iris set back darkening of the target field of view).

Camera Field of View Considerations
The NCP contains performance criteria in Appendix E for operational objectives which
have become widely adopted, however the criteria as presented are derived through
consideration of system end-to-end resolution which are difficult to apply from a design
perspective. They are referenced to a Rotakin target 160 cm high.
2. For the resolutions specified in this document, the maximum actual dimensions of the
subject as captured and viewed on the CCTV system between screen edges shall be as
shown in the table below.

In many cases the camera field of view will be bounded by walls or signs which are closer
together than the maximum width of the target. In such cases the limit of coverage is the
distance at which the target width would reach the maximum for a particular coverage
criterion if the camera’s field of view angle was extrapolated without being constrained by
occlusions.
a. The optical geometry shows that the coverage distance extends and the coverage
width contracts as the field of view is narrowed.
b. In order to minimise camera quantities, the coverage design must seek to
maximise the area covered by a camera at a particular grade by choosing the best
available compromise mounting height, distance from the coverage area and field
of view angle (determined by the lens focal length). For example, platforms are
long and narrow so coverage is optimised by choosing lenses with a very narrow
field of view located 20m or more from the start of coverage.

The camera coverage area for compliance to a particular grade or better assuming a
specific lens is determined by the achievable depth of field (which is influenced by light
level and camera sensitivity), and is bounded by the camera horizontal and vertical field
of view angles, the ground, and the maximum target width for the respective grade.
6. For estimating purposes it may be assumed that objects closer than 20% of the maximum
range are not in focus and therefore not considered covered by that camera.

The above figures lead to the following conclusions:
a. Providing escalators are close together, one (4CIF standard 4:3 aspect ratio)
camera can provide identification grade resolution for two escalators. The camera
must be close to the target image plane (5 m to 20 m), with the lens being selected
to achieve the required field of view for the respective distance of the camera from
the target.
b. For ramps, ticket gates and other choke points wider than 2.1 m, more than one
4CIF camera (or a Megapixel camera) will be required for identification.
c. Recognition will be possible on platforms towards the foreground of the image and
up to the distance where the image from side to side is 4.3 metres (or approaching
an island platform width). To achieve recognition up to 50 m away, the camera
must be zoomed to a viewing angle of 5°, requiring a long telephoto lens and an
optical path free from occlusions. At this level of zoom, objects near the camera
will typically be under or beside the camera field of view and out of focus, so the
effective field of view will commence some 36 m from the camera and the resulting
coverage area will be ~50 m². By contrast, a 2MP 16:9 camera will have a field of
view commencing 22 m from the camera and covering an area up to 218 m².
d. Monitor grade platform coverage may theoretically be achieved with one camera
looking down a platform with a narrow field of view, however centre platform
occlusions and the need to keep cameras within the field of view of other cameras
typically requires that two or more cameras be provided. Where practical, cameras
shall be planned on the basis of facing pairs.
7.5.

3.
Camera Location Planning
The minimum requirement for placement of cameras is determined by the coverage
requirements indicated in Annex 1 and the constraints of the associated site layout. In
order to rigorously determine the number of cameras required to provide the target grade
of coverage (as per PTV Level definition), it is essential that a graphical “to scale”
coverage plan be produced for the entire site which indicates the coverage of every
camera, thereby showing how the target coverage is met.
Additional cameras may be required for operational reasons including Single Person
Operation of Trains on curved platforms, and surveillance of areas subject to crime or
vandalism threats (such as car parks and associated walkways).
Additional cameras will be required if occlusions prevent the full range of the camera view
from being utilised.

Camera Positioning Considerations
In order to achieve a camera view with the required identification capability at choke
points, the camera must be directly in front of (and above) the movement direction of
patrons. Compromises made purely for aesthetic or architectural reasons will result in the
failure to meet objectives (e.g. a face side or top of head view as opposed to front face as
required for identification). Therefore, the design emphasis shall be on planning the
structure and architectural features to facilitate this. The diagram below illustrates typical
placement.
Platform cameras shall generally be located towards the platform edge to optimise the
viewing range and minimise the requirement for additional cameras to see beyond typical
platform occlusions such as suspended signs or PIDs.
Cameras necessarily facing east or west on outdoor platforms shall be positioned to tilt
down to avoid direct sunlight early or late in the day at particular times of year.
Cameras shall not be directly behind light fittings where the light could cause camera glare
or false iris (aperture) closure at night.
Where alternatives exist, cameras shall be placed to avoid extreme contrast or
backlighting at some times of day. For instance, facing an external door or window from
inside.
Cameras facing surfaces subject to wetting from rain may require fitting of polarising filters.

When planning camera views, the occluding effects of ceiling fittings like suspended
PIDs, signs, and platform fittings like advertising hoardings, wind barriers, or kiosks shall
be taken into account.
Where not restricted by ceiling heights, cameras shall be mounted in the range 3.5 m to
4 m from the ground surface and/or be contained in vandal resistant housings in all
potential vandalism areas.
Cameras shall be positioned to maximise coverage. For instance, cameras covering a
small rectangular space shall be fitted towards a corner of the space to allow most of the
space to be covered with a 60 to 80 degree field of view.
As far as is practical, every camera shall be in the field of view of another camera or the
un- occluded pan-tilt-zoom range to allow any vandalism attempts to be recorded.

Coordination
Internal and platform camera locations must be coordinated with other station design
disciplines.
Architectural coordination shall include:
a. avoidance of occlusion by architectural features, signs and advertising hoardings
or other items which may not show up on the base plan;
b. provision of architecturally acceptable mounting positions which still fulfil the
optical requirements;
c. provision of easily accessible Field LAN Switch mounting locations, preferably
recessed within walls or mounted in closets to achieve a clean aesthetic finish;
d. provision of cable pathways within structural elements where other options are
precluded by the architectural form, such as glazed canopies; and

where the existing equipment room is being demolished, or at upgraded stations
where the existing (DRU) rack is inappropriately positioned to support the new
requirements.
Electrical coordination shall include:
a. coordination of cameras with light fittings, both to avoid glare from lights directly in
front of cameras (especially flush ceiling mounted units) and to ensure ceiling
space is coordinated;
b. joint use of lighting poles for outdoor CCTV and provision of mountings and cable
gland holes for enclosures to house fibre optic terminations and media conversion
at the base of poles; finding best compromise pole location for both CCTV
coverage and lighting purposes; provision of dual conduits for communications
and power through the pole footings and base; provision of a means of
segregating ELV and LV cables within the pole; earthing of poles (to the site
earthing system where applicable);
c. provision of power into any new CCTV rack cabinets or equipment spaces;
d. provision of indoor cable trays and pathways and segregation from electrical trays;
e. trench sharing with lighting and power, notably in yards and car parks or for
outdoor racks (refer 8.16.3); and
f. provision of adequate light intensity (minimum mean illumination of 20 lux) and
spectrum (Colour Rendering Index > Ra80) in outdoor areas to maintain camera
performance at night [refer also to levels specified in Franchise Agreement
Amendment Deed (No. 8) – Train and fittings and luminaires specified in T707-ES01].
Lift Services coordination shall include:
a. provision of lift car cameras with trailing Cat 6 cables for Field LAN Switch links.
b. interfacing of duress alarms and lift phone to the CCTV system.
c. use of part of the lift shaft as a riser for CCTV cabling between levels and possibly
recessing a Field LAN Switch into the lift shaft structure.
Structural coordination shall include:
a. any structural aspects of listed architectural issues; and
b. provision of poles or structures to mount cameras (coordinate with landscaping).

Camera Coverage Plan
Platform cameras are usually zoomed to a telephoto setting yielding a viewing angle in
the range 5° to 20° with a lens focal length in the range 12 to 50 mm. On Level 2 and 3
stations this enables them to typically cover 100 m of platform, providing the platform is
not curved.
a. The coverage will only commence some distance (typically 20 m to 30 m) in front
of the camera. Therefore platform cameras must be positioned with an apparent
overlap of some 40m to 60m to avoid gaps in coverage.
b. Refer also to clause 7.3.4 regarding vertical field of view determination.
Wide fields of view between 30°and 80° with a lens focal length of 2.5 to 5 mm shall only
be used for “observation” cameras and/or cameras covering small spaces typically less
than 10 m × 10 m.
The intended coverage of every camera shall be marked by shading or a trapezoid shape
linked by a line back to the camera on a location plan drawing specifically provided for
this purpose (CCTV coverage plan) which will become one of the tender/contract
drawings defining the works.
This is typically a four part process using “shapes” tools or CAD construction lines:
a. drawing a transparent coverage construction triangle with base at the camera and
far end width set by maximum field of view width (refer 7.4.2)
b. overlaying a second 50% transparent shape or solid fill bounded by the
construction triangle just drawn, occlusions and start of vertical field of view
(clauses 7.3.3, 7.3.4) or minimum in-focus range (clause 7.4.6);
c. deleting the construction triangle, and
d. adding an arrow line joining coverage shape to camera.
The representation of cameras and coverage shall be in the standard PTV coloured and
shaded format on a background of the station architectural layout (with extraneous
architectural notes hidden or removed). The format and method of production is described
in the PTV CCTV Development Standard. The key items include:
a. Use of a coloured and filled circle to represent a fixed camera, with the coverage
area being a shaded trapezoid or irregular shape bounded by station walls and
objects which shows the areas on the plan that is visible in the camera vertical
field of view over a height range of 0m to 2m above pedestrian surfaces (which
may be sloping).
i. Shading shall be transparent so that overlapping coverage and edges are
visible on plot.

General Camera Selection Criteria
The choice of camera and lens will be dictated by the respective target coverage grade
(as indicated in Annex 1) for the site’s PTV CCTV coverage Level classification.
Fixed cameras are preferred for certainty of activity capture and for post incident forensic
analysis.
Pan tilt zoom (PTZ) cameras are required to supplement fixed coverage to allow close up
monitoring and capture of activity first observed on fixed cameras or for other operational
reasons.
a. PTZ cameras shall generally be placed in locations having extended optical sight
lines over a high proportion of azimuth angles.
b. Outdoor PTZ cameras, especially pole mounted units, may require image
stabilisation to compensate for image jitter under windy conditions when zoomed
to telephoto focal length.
c. PTZ cameras shall be programmed to revert to a defined home field of view after
the inactivity period time out (nominally 5 minutes). The home field of view shall
provide fill in coverage to improve the total coverage grade of the site.
d. Outdoor PTZ cameras linked with perimeter or door alarm systems shall be
programmed to automatically pan and zoom to pre-sets corresponding with a view
of the sector or door most recently alarmed.
Cameras with high low-light sensitivity better than 0.1 lux (possibly switching to black and
white mode under light levels below 0.8 lux) shall be used where night time coverage is
required under moonlight or emergency lighting conditions.
Infrared thermal imaging cameras capable of sensing body heat and operating without
any lighting shall be considered for emergency situational awareness applications in
locations that are permanently reliant on artificial lighting such as tunnels and underground
facilities.

Housings - General
Housings and mounting structures shall generally comply with AS 4806.2 Clauses 3.8,
5.3 and 5.4.
Housings shall:
a. Be compatible with the selected camera type, point direction and mechanical fit of
lenses to achieve the required field of view.
b. Have optical properties which do not detract from the achievement of the specified
resolution under day time or night time conditions.
c. Have a body and viewing window of strength to mitigate vandalism damage,
especially when installed at a height below 3.5 metres above finished ground or
floor level or within lifts.
d. Exhibit ingress protection rating suitable for keeping the camera dry and to prevent
the build-up of [pantograph] dust on the camera lens and on the viewing window
or dome inside the housing, especially on platforms and areas in the same air
space as rail track.
e. Where installed in uncovered outdoor areas, be of a type which includes a visor
to reduce the impairment of the camera image by sunlight and rain.
Where existing cameras are being replaced with new cameras, new housings shall be
provided. Old housings and cameras shall be recovered and returned to the ARO
maintainer for use as spares or disposal.

Housing access covers shall either have an integral lock with cylinder to suit rail operator
keying, or have integral tabs with holes to allow fitment of a padlock (fitted with rail
operator cylinder).
Housings shall be fitted with a (third party) spring level tamper switch (e.g. Radio Parts
Group SM4501) configured to close when the housing cover is opened, wired as follows:
a. For Metropolitan Rail stations and stabling yards: to the housed camera, Alarm
Input 1 terminals (with the exception of any cameras used to interface CHPs or
controls, which will not be tamper alarmed due to insufficient alarm inputs on
available and PTV approved cameras for the number of functions). Configuration
shall be to clause 7.15.
b. For Regional Rail stations: via 2-core security cable to an IDF or alarm contact
marshalling block in the Field LAN Switch enclosure, and from the IDF/marshalling
block to the nearest Security Panel or DGP in multipair or multicore cable (along
with alarms for all other cameras served by that enclosure and the enclosure
tamper itself).
i. Cables shall be underground rated if their route is partially or fully
underground.
ii. Configuration shall be to clause 7.16.
iii. Existing regional station analogue cameras should have tamper switches
separately wired to the station security alarm panel.

Housings - Indoor
In indoor and concourse areas where lighting levels and camera dimensions permit and
the ceiling height is over 3.5 m, tinted dome housings or cameras with an integral dome
housing are preferred to render the camera coverage ambiguous to the casual observer.
Specific candidate areas for the use of dome cameras include interior areas with high
suspended ceilings where flush domes may be used, notably:
a. station building concourses and waiting areas
b. enclosed bridges between platforms and to car parks
c. underground loop station platforms
Where the camera with lens will not physically fit into a dome housing of nominal
diameter
~300 mm (with tinted dome diameter ~210 mm), for instance due to a requirement to use
8 to 50 mm varifocal lenses to achieve the specified field of view, full-body in-line housings
may be provided. This avoids the aesthetic impact and wind loading of large domes.
The optical effect of the dome shall be taken into account when adjusting the camera
focus, so that the camera achieves best focus after the dome is fitted.
a. Where the suspended ceiling height is less than 3.5 m, a flush wedge housing
shall be provided. The housing shall be fitted with a lockable drop down bottom
access lid.
b. The camera lens shall be adjustable to align focus and field of view without
removing the camera or viewing window from the housing.
c. The viewing window shall be flat clear glass.
d. The housing shall be long enough to accommodate at least a 50 mm varifocal lens
having optical properties meeting this specification, with clearance to insert a
neutral density filter for focus alignment.
e. The housing shall have space for an in-line Cat 6 camera outlet and fly lead.
Where the ceiling height is less than 3.5 m and the ceiling is solid (such as a concrete
underpass ceiling), a vandal resistant surface mount wedge housing shall be provided,
meeting criteria a to d in clause 7.11.4.

a. The housing shall be affixed with #10 snake eye screws and be fitted with a
lockable drop down bottom access lid.
b. The housing shall be vandal resistant (e.g. to survive hockey stick and baseball
bat attack without camera damage). A galvanised steel mesh cage with a grid
space at the viewing window shall be provided if necessary to meet this
requirement.
Camera housings in lift cars are often subject to more frequent and serious vandalism
than those located on platforms or in elevated locations. Dome cameras have proven
susceptible in these environments, necessitating the installation of heavy duty corner
mount enclosures with a toughened glass viewing window. The housing shall meet the
requirements of 7.11.4, and shall:
a. have a viewing window of sufficient size to accommodate the wider field of view
required for lift monitoring.
b. Be fixed to the lift frame with security fittings to the manufacturer’s
recommendations.

All PTZ cameras (both indoor and outdoor) shall be provided with dome housings.
In platform, covered ramps and outdoor areas where the camera height is over 3.5 m, fullbody in-line housings with the following properties shall be provided for fixed cameras:
a. The camera lens shall be adjustable to align focus and field of view without
removing the camera or viewing window from the housing.
b. The viewing window shall be flat clear glass.
c. The housing shall be long enough to accommodate at least a 50 mm varifocal lens
having optical properties meeting this specification, with clearance to insert a
neutral density filter for focus alignment.
d. The housing shall have a sun shield with sun/rain visor.
e. The housing shall have space for an in-line Cat 6 camera outlet and fly lead.
f. Cables shall enter the housing via a cable path through a hollow mounting bracket,
or via flexible steel conduit to a housing gland.
In platforms, covered ramps and outdoor areas where the camera height is less than 3.5
m, wedge housings to clause 7.11.4 or 7.11.5 as applicable shall be provided.
Polarising filters may be required to reduce the effects of glare in outdoor areas which
may have wet surfaces after rainfall.
Where installed outside enclosed buildings or away from a covering roof, housings may
also require heaters to prevent condensation, notably in areas subject to high peak rainfall
rates or elevated and inland areas subject to frost. (Where heaters are provided for PoE
IP camera housings, a 2.5 mm² cable to a power supply source [DC-DC converter to
heater supply voltage] at the Field LAN Switch enclosure will be required in addition to
the standard Cat 6 camera cable).

Camera Lenses
Lenses for fixed cameras shall be selected to achieve the field of view required for the
respective camera duty as detailed in the PTV Level definition (refer to Annex 1) and the
standards defining them (NCP, and AS4806.2, especially clauses 3.6, 3.7 and 5.4.2).
A varifocal lens shall be provided to allow the camera field of view to be adjusted to match
the target shown on coverage diagrams or schedules. If possible (by choice of lenses with
appropriate optical properties), the site requirements shall be met by two standard lenses

with overlapping focal length ranges such as 2.5 to >8 mm and <8 to 50 mm. The focal
length ranges shall be chosen such that at least 80% of cameras will exhibit a resulting
adjustment within the optimal image quality (resolution) range, thereby not requiring
adjustment to within the first or last 15% of lens focal length travel.
The following guidance is offered regarding lens selection:
a. 2.5-10 mm varifocal lenses are generally used where a wide field of view at short
range is required, such as:
i. Enclosed waiting areas, enclosed platform and bus interchange shelters
ii. Broad concourse or station entry views
iii. Inside lift cars
iv. Choke points having cameras in close proximity
v. Equipment rooms
b. 5-50 mm varifocal lenses are generally used where a narrow field of view covering
a long range is required, such as:
i. Platforms
ii. Rail yard fences
iii. Pedestrian tunnels and corridors
iv. Choke points
v. CHP intercoms
vi. Car parks
c. Refer to clause 7.3 regarding field of view considerations and Annex 2 regarding
Field of View angle versus camera lens, range and coverage.
d. Megapixel cameras shall be fitted with lenses that allow their rated end-to-end
TVL resolution to be achieved.

Camera Focus and Alignment
Each camera shall be aligned and focussed by the Contractor in accordance with
directions from the DA.
Alignment and focus settings of fixed cameras shall be conducted with the camera being
aligned in low light conditions (for outdoor cameras, or for indoor cameras situated in
locations where lower lighting levels after hours or during station close apply). Either the
activity shall be conducted:
a. at night at the time of lowest lighting levels;
b. during day time with neutral density filters inserted in front of the camera lens
ensuring light reduction of > 99.9% [~10 f-stops or 1000×] in bright sunlight, or
>99% [6.5 f- stops or 100×] in overcast weather; or
c. automatically (typically only auto-back focus capable megapixel cameras) with
confirmation by review of night time recordings.
PTZ cameras shall be confirmed to sharply focus at any zoom setting. PTZ camera home
position and pre-set coverage shall be set where defined on Camera Coverage Plans or
camera schedule target view descriptions.
Following completion of alignment and focus (or PTZ pre-set setting) to the satisfaction of
the DA, the Contractor shall provide a copy of a Camera Definition Sheet per camera for
maintenance records, including a snapshot of the approved camera view (or all configured
pre-sets in the case of PTZs).
In addition to DA representative viewing cameras at the DA’s workstation, fixed CCTV
cameras may be focused using a portable monitor of at least 26 cm diagonal screen or a
portable computer with 30 cm (12") or larger screen. The focus process will typically
include the following steps:

a. If focus adjustment must be executed via viewing of the H.264/MPEG-4 stream,
the key (I) frame rate may be temporarily set to 1 second or less to ensure that
the viewed image updates fully in near real time as the focus ring is moved,
thereby avoiding confusion due to H.264/MPEG-4 encoding causing a gradual
softening of the image focus through successive difference (P) frames (due to
camera noise) and jumping back into focus on the next key frame.
b. If the focus is being executed under normal light conditions, one or more optical
neutral density filters shall be placed in front of the lens to simulate low light
conditions. (As the light level reduces, the lens iris opens, reducing the depth of
field). Focusing under low light conditions will ensure that the centre of the
intended field of view remains in focus under all light conditions.
c. The distance of optimal focus shall be in the centre of the target field of view range.
(For example, if the camera is covering an area ranging from 20 m to 100 m in
front of the camera, the optimal focus will be set at 60 m from the camera). If the
camera is covering a choke point (gate, ramp, stair or escalator), the focus shall
be sharpest at the centre of the choke point, (that is, where the choke point width
extends from side to side of the screen when viewing the camera on a monitor).
d. The housing cover / window shall be checked for cleanliness on internal and
external surfaces. Any de-focus effect of dome housing windows shall be
accounted for by holding the dome window in front of the camera during focus
(domes may be held "back to front" in front of the camera) and rechecking final
focus with the dome in its normal position before final lock down. The housing
window shall be replaced if it causes a degree of de-focus (due to manufacturing
flaw or fine scratches) which cannot be corrected by practical adjustment or if it
does not allow the target end-to- end resolution to be achieved.
e. After executing the focus procedure and before re-installation, the viewing window
or dome shall again be cleaned with lens cleaning products to remove any marks
or fingerprints inside. After reinstallation the window shall be similarly cleaned on
the outside.
f. If the H.264/MPEG-4 stream key frame interval was temporarily shortened to
assist with focus adjustment, it shall be reset to its normal SOE value (three
seconds).
Camera Tamper Alarm Configuration – Metropolitan Stations
7.15.
1.
2.
3.
During system commissioning, the operation of the CCTV system shall be configured to
respond to tamper alarms sensed on cabinets or in cameras.
For cameras, the sensing may be by:
a. the housing cover tamper switch being operated, or
b. an alarm generated by basic camera analytics to sense fixed camera movement,
masking of the viewing window or de-focus.
The system shall be configured to respond to tamper alarms as follows:
a. Bring up a tamper alarm on the VicTrack Call Centre security monitoring
workstation alarm list.
b. If the tampered camera or enclosure is within the viewing capability of a PTZ
camera, to pan and zoom the PTZ to a pre-set close up view of the respective
device and hold it there for a pre-set configurable time period (nominally 60
seconds) before resetting to the home position.
c. Pop up the live PTZ camera view (or if no PTZ, the view of another fixed camera
having coverage of the area under the alarmed camera) on the VicTrack Call
Centre security monitoring workstation screen alarm spot window.

Above ground surface run conduits shall be white or grey indoors, and white or
black with UV resistance if exposed outdoors.
i. Exposed surface run conduits at a height of less than 3 m above ground
or floor level on surfaces or structures in public accessible areas shall be
of galvanised steel construction secured with tamper resistant fittings.
Pathways shall be in accordance with TS-ST 043. In summary, this requires that
they be planned such that:
i. Conduits shall enter rectangular pits of width (shortest side) less than 500
mm at the ends (not the sides).
ii. Pits are sufficiently deep to allow entering conduits to meet depth of cover
criteria into the pit without any vertical plane bends, and to allow at least
1:300 drainage slope on the end to end conduit run (300mm drop over a
100m run).
iii. Rigid conduit is used exclusively in all underground runs and for all haul
routes of over 10m length.
iv. Rigid conduit bends with inspection openings or draw access junction
boxes are provided for above ground conduit runs where the cumulative
sum of bend angles exceeds 180° (horizontal or vertical, -both planes must
be considered) between draw access points.
v. Conduit occupancy by proportion of sum of cable cross sectional areas to
the conduit inside cross sectional area shall not exceed 25% for any new
installation (to achieve a nominal 50% future overhaul spare capacity
based on a 35% maximum occupancy criterion nominated by PTV).
The system design shall be efficient and optimised within the geographic site
constraints. The system architecture shall minimise the count and spread of
components with the aim of maximising reliability; reducing maintenance,
documentation and administration costs and minimising spares holdings.
The system architecture and distribution shall minimise the number of cables and
connections on any circuit. Joints in cable runs shall be avoided apart from fibre
splices and transitions to trailing lift cables. Fibre splices shall be within distributors.
The system architecture shall minimise the number of LAN switches and maximise
the number of cameras served by strategic positioning of the switches.
On all sites with less than 150 cameras, the site LAN shall only require two Gigabit
Ethernet fibre interfaces to the Site Master switch.
i. This criterion shall be met by configuring all switches outside the CCTV
Rack into a gigabit Ethernet fibre loop.
ii. The 1000baseSx standard of transmission used requires that the total
length of fibre between switch interface ports be less than 550m.
Aggregate lengths shall be considered when planning the site distribution,
especially where Field LAN Switches are located 200m or more from the
CCTV rack.
Within the CCTV rack, field LAN switches shall be 240V UPS powered and
uplinked to the Site Master Switch via dual 1000baseT UTP connections.
All major system components shall be remotely managed and alarmed using
Simple Network Management Protocol (SNMP). Note that where DVTel
components do not support SNMP monitoring, they shall be monitored through
the DVTel software, however all SNMP capable CCTV components shall have
SNMP alarm traps activated and configured.
All Line Replaceable Units (LRU) of equipment shall be connected to the system
via plug and socket connections. Where the equipment interface has direct hard
wired connections (e.g. screw terminals), an in-line plug and socket shall be

provided, with the plug (male) connector being on the equipment. All spares shall
be fitted with the respective plug.
s. All low level signal, fault/alarm signal, relay contacts and voice frequency
interconnections between equipment items shall be via jumpered IDF
connections. All the equipped signal interface ports of each item shall be wired out
to the IDF via a tail cable, with only those actually used being jumpered.
t. The VicTrack MDF shall be the primary point of administration of services between
systems. Telephone pair cable interconnections between equipment cabinets for
differing systems and between systems and VicTrack or Telstra copper services
shall be achieved by providing tie cables from the respective cabinets to the site
MDF and jumpering at the MDF.
u. All IP cameras shall be powered by Power over Ethernet (POE – IEEE802.3af).
PTZ cameras shall be powered by PoE+ (IEEE 802.3at), using POE+ injectors at
the serving Field LAN Switch or media converter enclosure where the Field LAN
Switch or media converter ports do not support PoE+.

Recording Quality
The primary objective of recording camera images is the achievement of optimum image
quality which includes a high probability that one or more images of a station incident will
provide material of evidentiary quality. For this reason the digital recording system shall
support recording of 25 frames per second (fps) per video stream or camera.
The digital recording system shall be configured for a minimum of 4CIF (704×576 pixels)
on all standard definition cameras or streams. Higher definition (typically 24CIF or
1920×1080 pixels) may be used to achieve reduced camera counts where the grade of
coverage over a significant area is identify or recognize.
The recorded CCTV image stream encoding format shall be ISO/IEC Moving Picture
Experts Group type 4. Generally MPEG-4 [Part 10]-AVC / ITU-T Rec. H.264 shall be
implemented at all new and stand-alone sites, with MPEG-4 [Part 2] compliance as a
minimum being achieved elsewhere. The profiles shall be in accordance with the DVTel
Latitude v6 NVMS.
The encoding format for any recorded audio shall use synchronised MPEG-1 Audio layer
2 compression for MPEG-4 [Part 2] systems, and AAC (advanced audio codec) for
MPEG-4 [Part 10] / H.264 systems.
The recording quality settings that adjust the levels of image input filtering,
compression/quantization increment, frame rate and bit rate for the MPEG-4 stream shall
generally be configured for constant frame rate (normally at 25 fps), minimum or near
minimum compression (in terms of image "quantizer" and "quality" settings) and minimal
input filtering.
a. The standard PTV SOE settings are described in the DOT “CCTV Metropolitan
Network Stage 1 and 2 Design” document and include optional “time of day”
settings for cameras operating in difficult night lighting environments (that cause
high levels of camera imager noise).
b. Network devices and recorder hard drive sizes shall be selected on the basis of
the resulting bandwidth and traffic.
c. The quality settings shall not cause the image resolution to fall below the minimum
optical (monitor TVL) resolution as a result of smearing or pixilation caused by
compression artefacts.
The end-to-end optical horizontal resolution (vertical lines) from the camera view to the
replayed image on the supplied monitor (including the housing window, optical filters, lens,
camera, H.264/MPEG-4 encoder (for non-IP camera), storage and replay through to the
viewing monitor screen) shall be better than:
a. 400 TV lines (4CIF) or 800 TVL (24CIF) for all camera lens zoom settings (for
varifocal lens equipped or PTZ cameras) and moving scenes at the specified
frame rate.

streams:
Date and time in the following format and resolution:
a. The following format shall apply to the timestamp applied to every recorded image:
yyyy-mm-dd HH:MM:SS.hh ZONE where:
The whole timestamp represents local time, YYYY is the calendar year
MM is the calendar month 01 to 12 DD is the day of month 01 to 31 HH is the hour
00 to 23
MM is the minute 00 to 59
SS is the second 00 to 60 (60 being relevant on a leap second insertion) hh is
fractions of second, in this case to a precision of 1/100th's (10ms) ZONE in our
case (Melbourne) is either "AEST" or "AEDT"
Note that at 25 fps the fractions of second shall advance in 40 millisecond
increments, however each individual image shall be unambiguously time stamped
regardless of frame rates.

“CCTV Metropolitan Network Stage 1 and 2 Design”, summarised in the diagram below.
The site master Security LAN switch shall be interfaced to the Security Network in two
directions of transmission (up and down the line) using single fibre wavelength division
duplex interfaces optically and electrically compatible with others in use on the respective
line.
The switch shall be configured to route traffic via the down link direction if the uplink fails
(by means of OSPF and associated link cost allocations) and shall route any through
traffic from other nodes on the line.
Where a number of other stations on the same line already have active CCTV site
switches, the fibre patching shall be reconfigured so that a “flat” logical ring architecture
is achieved with repeaters at every second node on the ring.
Prior to changing or upgrading a site on the network, PTV shall be consulted to arrange
a traffic baseline snapshot for the network through to the archival site. The ability of the
network to carry the additional traffic resulting from the respective upgrade works (and
the addressing, filtering, PIM routing and connection requirements for any new switch for
new stations) shall be confirmed with PTV and the changes implemented in accordance
with a PTV approved Transition Plan (Refer to clause 14.5).
An additional repeater switch shall be provided at a station half way between the “works”
station and the nearest active node if this is more than 10 km cable run length distant.

Metropolitan Station CHP (Emergency Intercom) Interfacing
The existing "green and red button" customer help point and emergency intercom system
(CHP) at metropolitan stations will continue to be used at the respective station being
constructed or upgraded. This comprises a Dallas Delta hands free panel-mount phone
connected to a VicTrack analogue PABX extension, pre-programmed to dial customer
help recorded announcements or emergency answering point numbers respectively if the
green or red button is pushed.
The emergency intercom is answered on the respective line control station operator's
telephone, and the operator is presented with the associated camera view on the control
desk CCTV monitor. The intercom signal is standard PSTN analogue telephony with
Dual Tone Multi-Frequency tone signalling. When the red emergency button is pressed,
an auxiliary relay contact is closed and can be used to trigger sound recording at the local
station and camera view switching at the control station. [In the future a Voice over IP
(VoIP) intercom system may be introduced and the Dallas Delta/PABX system phased
out].
The CCTV system at the “works” station shall continue to provide functionally equivalent
alarm triggered spot views, camera tours and monitoring of emergency intercoms at the
respective line control station as for other stations on the same line.
All new CHP emergency intercoms resulting from new platforms being provided or
existing platforms being extended under the “works” shall be interfaced to the digital
CCTV system and the respective interfaces and control station tours provided and
configured to match the existing Emergency Intercom operation.
At the control station, integration will be limited to provision of any additional workstation
monitors, revision of interactive camera selection maps, and programming of map icons,
camera tours and spot monitor / alarm triggers.
Emergency lift phones and duress alarms operate in the same manner as the CHP red
button function and shall be interfaced by a similar method with similar functionality. The
emergency call answering point and viewing workstation is at the VicTrack Call Centre.
Lift phones have a single line with handsets (and call buttons) at the upper and lower
landings, and within the lift car.
When a lift phone call is made, the VicTrack call centre monitor tile shall spot to the
respective lift car or landing camera.
The alarm contact for each handset shall have its signal split at the CCTV IDF via isolating
diodes to both the CCTV encoder alarm inputs and the lift SNMP alarm interface unit.
If the station is new, the scope of works shall include the configuration of remote viewing
facilities on the respective line control station control desk’s (and in the case of lifts,
VicTrack call centre desk’s) existing workstation.
It is assumed that the VicTrack fibre CCTV network will be extended to all new and
upgraded metropolitan stations as part of the respective station upgrade project.

i. Located in the monitor enclosure and provided with Cat 6 outlets wired
back to the nearest Field LAN Switch, patched to Field LAN Switch
100baseT ports.
ii. Located in the SPOT monitor enclosure together with their own Field LAN
Switch.
iii. Located in a suitably large Field LAN Switch enclosure, with video outputs

DVI/HDMI extenders (High Definition Digital) to the monitor inputs in the
SPOT monitor enclosure.
d. For any new installation, a minimum spare equipped port capacity for one
additional camera shall be provided at every Field LAN Switch.
e. Individual Field LAN Switch power consumption of at least 100W shall be
supported whilst maintaining voltage drop under 12% or 6V DC (yielding a 48V
terminal voltage with the central 48V DC supply configured to 54V output). Where
two Field LAN Switches are fed by one conductor pair, a combined load of 200W
shall be used for voltage drop calculation from the first switch to the 48V DC Main
Distribution Board.
f. A pair of fibre circuits from every LAN switch to any neighbouring LAN switch on
the same fibre run shall be provided to facilitate network looping.
g. A least two fibre pairs shall be available for future PIDs and customer help point
applications on platforms and around station buildings.
h. Local fuses or circuit breakers for all active equipment shall have trip current
coordinated by design with control room power distribution circuit breaker trip
currents so that an equipment fault will always interrupt its local fuse or breaker
rather than tripping the main control room supply. Fuses shall only be provided in
the active polarity of the supply (- for 48Vdc, + for 12Vdc).
i. The selected DC cable shall allow the same components to be used at run lengths
of up to 500 m from the Control/Equipment Room.
j. Batteries or mains powered devices or mains cabling shall not be used for the
CCTV camera power distribution outside the Control/Equipment Room. Mains
cabling shall not be run within CCTV or other communication pathways. Products,
sheath colours and labelling shall be selected to avoid any confusion as to the
voltage carried (refer to clause 8.4.1 d).
k. All cables running through underground conduits shall be of water blocking
construction which prevents moisture propagating through the cable even if the
sheath is damaged.
Applying the above criteria, the minimum provision for a typical 165 m long island platform
is two Field LAN Switches. Three or more may be required on sites classified PTV Level
1 or having a curved platform with a SPOT camera system due to the combination of
camera count and pathway routing limitations.
Standard distribution methods are detailed in section 13.

joints) and use sweeping bends at corners (not elbows).
b. The minimum conduit size on backbone runs shall be P100, and P50 for spurs
into poles and media converter enclosures. Spur connections from pits to Field
LAN switches shall be a minimum of 1×P100 or 4×P50.
c. Rectangular pit sides shall be aligned parallel to surrounding platform, kerb, path
or building lines.
d. Conduits shall be planned to enter any rectangular pits at the ends and changes
of direction shall generally be achieved by bends of up to 90°in the conduit run.
e. Changes of direction shall only otherwise be allowed within square pits of

Safety
Safety of installers and maintainers shall be considered when planning and specifying the
placement of cameras and Field LAN Switches. Refer also to clause 7.3.3.
Cameras shall not be located closer than 500 mm of the platform edge. This typically
means the entire outside surfaces of camera housings must be located behind the yellow
safety line on the platform. Refer also to clause 7.3.10.
Provision for scissor lift or bucket truck access must be available for cameras higher than
4 m, and/or a swinging arm provided allowing the camera to be lowered for maintenance.
Cameras located at ladder access heights (< 3.5m to lowest point of camera housing)
shall not be located over drains or other obstacles hindering safe ladder placement.
Field LAN Switches in buildings and on platforms should be integrated with the building
architecture (by recessing into walls, shafts or closets) on station upgrade projects.
Where Field LAN Switches must be surface mounted on walls or free standing on
concrete pads, they shall be positioned away from main thoroughfares or have sides or
covers extending to the ground footprint to minimise the risk of injuries from patrons
bumping corners (notably visually impaired or short persons).
Field LAN Switches in car parks shall be provided with protective steel bollards if the
selected position could be subject to vehicle impact.

1.
2.
In addition to supporting the general image resolution and sensitivity requirements of
clauses 8.7.6 and 1, cameras (and encoders for legacy cameras) for fixed CCTV
installations shall have the following capability:
a. H.264/MPEG-4 IP multicast streaming output capability at 25 fps constant frame
rate at 4CIF resolution. Frame rates, resolution, input filter and video
quality/compression settings shall be programmable via a remote workstation or
automatically configured under NVMS time of day control, and configured for
optimum resolution. (The PTV Design Authority will provide settings for DVTel
Latitude NVMS based systems).
b. Power consumption and operating voltage to facilitate a remote power feeding
strategy (via PoE for fixed cameras).
c. IEEE 802.3 (Ethernet) interface, preferably directly on the camera, otherwise via
an encoder in the same housing.
d. Support for time synchronisation and camera identification and location data to be
derived from a connected video archiver (recorder) or the operating system
software.
e. Native IP cameras with firmware to suit the DVTel NVMS shall be used in
preference to analogue cameras with external encoders in (or near) the camera
housing unless a special requirement exists. Cameras shall be selected from the
range of cameras compatibility proven by PTV and having established spares
holdings. Refer to the PTV “Approved Equipment List”.
In addition to the general image resolution and sensitivity requirements, cameras (and
encoders for legacy cameras) shall behave well (as detailed below) in the IP networking
environment including QoS compatibility, Real Time Protocol standards compliance and
firewall compatible IP Port assignment for H.264/MPEG-4 streams. IP cameras and
H.264/MPEG4 encoders shall:
a. be configurable to set IP DiffServ bits to Expedited Forwarding (EF, 46). [If the
cameras or encoders cannot do so, the site master switches shall be set to EF for
all multicast traffic originating from cameras and encoders at the site].
b. have Ethernet back pressure enabled.
c. provide Real Time Control Protocol (RTCP) streams associated with the Real
Time Protocol (RTP) streams, making information about the connection available.
d. use standard destination ports as prescribed by the standard (RFC3550) for the
Real Time Protocol (RTP) streams and the corresponding RTCP stream.
e. use the same RTP Payload Type (PT) for key frames and non-key frames.
f. increment UDP source port numbers for the same stream in irregular intervals, to
avoid exhausting connection space in firewalls.

Field LAN Switches
Field Local Area Network (LAN) switches shall be provided for camera connections to
achieve a planning target of less than 70m (and a constructed maximum of 90m) of Cat
6 cable run between each switch and served cameras.
a. The general strategy shall be to create a series of regularly spaced network
connection nodes around the station to simplify future moves, additions and
changes.
b. Subject to the 90m cable run length criterion, as many cameras as possible may
be cabled to a POE CCTV rack.
Locations and pathways shall be carefully planned to allow the number of field LAN
switches to be minimised (refer to clause 8.4.1 n).
a. Where the field LAN switches are being delivered as part of a station upgrade, the
design should seek to integrate them with the building fabric to avoid an “add on”
appearance. Opportunities may include providing shallow closets under stairs or
escalators, or on lift shafts.
b. Field LAN switches may be located on, or adjacent to, poles carrying one or more
cameras, providing the LAN switch does not protrude into public circulation space.
However pad-mounted free standing cubicle enclosures located part way between
camera poles are preferred if this allows the switch to serve more cameras over
Cat 6 UTP.
c. Some cameras may be connected to field LAN switches via 100baseFx over
MMOF to achieve a planning target of at least four cameras per field LAN switch.
Subject to provision of suitable secure enclosures for the LAN switch and associated
backbone and camera cable distribution, Field LAN Switches may either be:
a. Fanless Industrial 48V DC powered LAN switches having dual 1000baseSx OM3
fibre uplinks, IEEE 802.3 af compliant PoE ports (and optionally 100baseFx ports)
for cameras, installed in uncontrolled environments;
b. Office environment rated 240V ac mains powered PoE switches with dual
1000baseT uplinks powered from the CCTV UPS when located in the CCTV
equipment rack; or
c. Office environment rated 240V ac mains powered PoE switches with dual
1000baseSx OM3 fibre uplinks when located in any 24 hour controlled
environment with its own UPS backup power and essential (diesel backed) power
supply. (Typically such a location would be a satellite Telecommunications Room
at a major manned station or rail yard).

CCTV Interface Wiring to Security System
The wiring of security system alarm outputs and inputs to the CCTV IDF (or to a Field
LAN Switch IDF) is normally part of the scope of work for the sie’s Security and Access
Control System. The wiring between every controller terminal and the corresponding door
controller terminals or DGP will be detailed in a Security and Access Control “Gate Control
System Schematic”.
The jumpering of the Challenger I/O to encoder, decoder and/or camera alarm inputs and
outputs is part of the CCTV works scope as follows:
a. The next available encoder (camera) inputs shall be assigned to Challenger panel outputs
after inputs have already been assigned for all CHP relays and lift intercom contacts. One
input shall be assigned per controlled gate or door.
b. One encoder (or decoder, camera) output shall be assigned per controlled gate or door
to Challenger panel inputs (DVTel relay outputs are not normally used for any other
purposes).
c. Jumpers and signal service descriptions shall be assigned in jumper records.

REQUIREMENTS FOR MINOR ANALOGUE CAMERA
ADDITIONS
12.1.
Applicability
1.
2.
3.
4.
This section describes requirements for the addition of up to three to four analogue
cameras within the 200 m RG6 coaxial cabling range of the CCTV rack to a metropolitan
station or site.
The most common context are provision of several cameras:
a. around a car park as part of a Park + Ride car park expansion.
b. around a stabling yard as part of a minor rearrangement or security upgrade.
Pre-requisite conditions for the CCTV rack (supplied under the DRU) are that:
a. space exists for an additional encoder, or pre-equipped encoder port capacity
exists, as required to connect the additional cameras.
b. space exists to install a new 24V AC power supply and distribution panel.
This approach shall not be used
a. on new stations or stations or stabling yards being extensively redeveloped.
b. where the cameras are beyond the reach of an un-repeatered RG6 coaxial cable
home run from the CCTV rack.
i. For such long runs, the standard approach shall be the provision of
standard digital CCTV network infrastructure including an unduplicated low
capacity (150W) 48V DC central power supply (UPS backed), 48V dc and
OM3 fibre distribution, and Field LAN Switches or fibre media converters
to connect PoE IP cameras.
ii. The use of analogue video fibre transmitters and receivers to extend
analogue camera range is not approved because it represents investment
in equipment, spares, and training for an obsolete technology, negating
any marginal cost savings.
iii. Under particularly difficult conditions, a wireless Ethernet bridge with
locally backed up power supply may (subject to PTV approval) be used to
connect a distant camera.
12.2.
1.
2.
Cameras
Camera selection, housing and placement shall generally comply with clause 2.
Cameras shall be synchronised to the common 50 Hz UPS backed mains supply via the
24V ac power supply.
12.3.
1.
Cabling
Cabling shall comprise the following cables home run together from the CCTV rack to the
respective camera locations and terminated on the patch panel or power supply connector
as applicable:

CAMERA DISTRIBUTION INFRASTRUCTURE
13.1.
Distribution Topology
1.
2.
The physical distribution topology is dependent upon the following site factors:
a. The position of the Control/Equipment Room or CCTV Rack within the site, in
particular whether it is located towards the centre or towards one end.
b. Whether the station comprises two marginal platforms or one or more island
platforms.
c. How far the station extends beyond the platforms.
d. Whether the station site is long and narrow with car parking at the ends, or short
and wide with car parking situated parallel to platforms.
As a result of the varying layouts, one or both of the following three distribution scenarios
will normally arise (supporting diagrams reflect electrical circuits rather than physical
layout):
a. Star distribution (Default method): each Field LAN Switch has its own dedicated fibre
and 48V DC backbone to the CCTV rack. A LAN fibre loop serving the station interfacing
to a pair of site switch ports is created at the CCTV rack via the patch configuration at the
fibre patch panel.

b. End fed physical bus distribution: Starting from the CCTV rack, backbone power and
fibre cables daisy chain through up to three switches along a single run route. The optical
fibre cable retains the same core count along the full run. All fibres are fully terminated at
every Field LAN Switch box (for both cable ends on intermediate boxes). Refer to the
diagram below which shows the maximum possible extent of this topology, as might apply
on a long and narrow car park.

Field LAN Switches are identified by a “run number” numeric designation and alphabetic
character suffix (A, B, C...) increasing with run length from the CCTV rack. (Switch 1A is
a 240V ac powered unit located in the CCTV Rack and is directly up-linked to the site
switch, therefore the first Field LAN Switch outside the CCTV rack will be designated 2A).

b. an index sheet and divider tabs for all sections
c. a section giving supplier, installer and maintenance contact details
d. holders for optical media containing the electronic file version
e. all deliverable documents and drawings listed in the CDRL
System diagrams, station distribution schematics, rack wiring schematics, room and
station layout plans, jumper records and patch records shall be supplied electronically in
both native editable and PDF formats, and shall comply with AS 3085.1 and AS 4383 (all
parts). Where the requirements of AS 3085.1 are shown as informative, they shall be
treated as normative (mandatory) for the purposes of the respective CCTV works.
Drawings shall generally use symbol sets complying with relevant Australian Standards
including all those referenced in AS 3085.1 and AS 4383.
Station layout, cable route and location plans shall generally comply with VRIOGS 007.2.
Drawings shall comply with the VicTrack Drawing Management System standard
conventions. In particular, the following aspects of DMS compliant drawings shall be
noted:
a. The drawings shall be A3 sized and comprise a high level overview “index” sheet
followed by detail sheets which would generally be different paper part views of a
single model space. Where it is proposed to use A2, A1 or A0 contract drawings
as the basis of DMS “As-built” drawings, the large sheet shall be configured into
multiple A3 paper space sheets along boundary lines which maintain closely
related items on the same sheet, and generating a new index sheet. Text and
further identification to link line work between adjacent detail sheets shall be
provided.
b. The index sheet shall be a genuinely simplified overview providing a high level
summary of the drawing content and the detail sheet boundaries. Re-scaled
versions of the whole original drawing which are effectively zoomed out views of
the detail sheets without high level simplification are not permissible.
c. The drawings will require extent or point East/North markers to be identified in the
title block which will typically be the station extents for station layouts and
schematics, and the equipment room centre point for room and rack layouts, wiring
and mains power distribution.
d. Visio file format drawings do not comply and will not be accepted for as-built
records.
Schematic drawings shall adhere to the following conventions:
a. Schematic wiring diagrams and rack layouts shall be genuine schematic
representations like the examples appended to this guideline. Drawings
comprising photographs or pictorial images of physical products joined by line
work will be rejected. [Contractors may elect to produce such drawings as
additional information for installers for their own purposes, but such drawings will
not represent contract deliverables].
b. Schematic wiring diagrams shall be laid out in a manner which reflects the physical
layout. For instance, if the equipment room is in the centre of the station, the
distribution schematic shall show cabling radiating out from the centre of the
drawing in both left and right directions, and in an order matching the platforms.
