Overview
3.1
Introduction
HALO is a bistatic radar, Perimeter Intrusion Detection System (PIDS). The system is comprised of HALO
Transmitter (TX) and HALO Receiver (RX) pairs. The HALO is a platform based system which operates
at distances ranging from 3 – 100M.
The HALO has both RS485 and Ethernet connectivity for configuration and integration. Each HALO is
software configurable as a TX or RX unit.
HALO brackets (part code HALO-BRK) are available for mounting a set of units to a pole of >40mm ø.
Due to the unique design of the HALO, cross-hatching installation is not required. This reduces pole
numbers
3.2
Theory of Operation
The HALO system consists of pairs of TX’s and RX’s. The system detects the presence of objects moving
through the detection zone created by each TX / RX pair. On detection of an object an alarm is generated
which can activate any of the following:

Detection Characteristics
Detection Requirements
The HALO will detect any object with a mass > 35Kg moving through the detection zone created by
each TX/RX pair. Figure 1 depicts a side view of the detection zone of the HALO.
Figure 1: HALO Detection Zone side view
The HALO has eight software configurable sensitivity settings which make the HALO suitable for
installations in multiple environments and locations. The height and width of the detection zone varies
due to software configurable sensitivity level assigned to the RX. The sensitivity level effect on the beam
width is depicted in Figure 21.

Figure 2 is not to scale. The beamwidths for each sensitivity level are exaggerated in order to demonstrate the
effect. The data is based on a 100M link.

4.2.1
Typical Detection Patterns
Microwave
Microwave bistatic radar links have a detection zone which is ellipsoid in shape, i.e. the detection zone
is widest at the middle of the link and narrowest at either side of the link. The width of the detection
zone of the HALO is no greater than 5m.
4.2.2
Deadzone
Traditional Microwave systems have a ‘dead zone’ within which intruder movement may remain
undetected by the system, as the forward scattered multipath signals generated by the movement of
the intruder may be at a level lower than that which may be discerned from noise at the receiver. The
dead zone is located (i) on the ground directly below and in front of their transmit/receive antennas, (ii)
above the transmit/receive antennas, as shown in Figure 3.
Figure 3 Bistatic radar detection zone side view – dead zone dimensions

HALO
Detection Characteristics
The deadzone length l in Figure 3 is < 4m with an HALO mounting height of 1.1m.
The HALO is fitted with LOWER DEADZONE elimination modules which provides coverage of the “Lower
Deadzone” area not covered by traditional microwave systems. UPPER DEADZONE elimination modules
are also available. HALO with Upper Deadzone Elimination Modules (HALO-UDZ) can be purchased
from Sensurity.

6.1
Site Planning
Ensuring the suitability of a site for installation of the HALO system is imperative. A site survey prior to
install should be carried out to ensure that nodes are located in such a manner as to be most beneficial
to the site.
6.2
Foliage Management
It is recommended to keep foliage within the detection zone to a minimum. Foliage encroaching on the
detection zone may result in false alarms due to movement caused by wind. It is not advised to have
trees directly within the detection field as their movement due to wind may cause alarms.
6.3
Uneven Terrain
The operation of a HALO link requires transmission of energy from the transmitter to the receiver it is
therefore recommended that there is line of sight between the transmitter and receiver units. To ensure
a clear line of sight between the units the ground must be flat across the detection zone. A slope is
permissible however troughs or hills may shadow the beam and thus allow crawl spaces (dead zones)
for an intruder. See Figure 5. The protected area can be made up of any surface such as tar, concrete,
grass, tilled earth or gravel
Figure 5: Uneven Terrain
6.4
Rain, Standing Water and Frost
The HALO is unaffected by rain, frost and snow. Fast flowing water in the detection zone (such as streams
etc.) may cause alarms and it is thus recommended that the detection zone be free from streams or
large pools of water.

7.1
Installation Procedure
Pole Mounting
The HALO should be mounted on a pole of diameter no less than 40mm. A mounting height of 1.1m is
recommended. The mounting height given is relative to ground level, of the midpoint of each TX/RX
enclosure.
Figure 6: Halo Mounting
7.2
Alignment
TX/RX enclosures for each link should be mounted at the same height and be facing each other with
clear line of sight. The maximum offset of the devices should be no greater than 6° to ensure maximum
operational capability.

Intruder Settings
Operating Mode
The signal settings – Bisatic Radar controls the settings for the microwave detection zone. Operating
Mode has three options – Transmitter, Receiver or Bidirectional. Each device must be configured as
either a Transmitter or Receiver. Bidirectional operation is not operational on these devices. For each
pair of nodes there must be one device configured as a Transmitter with its paired node configured as
a Receiver.
Channel
37 channels are available. Any channel can be used for a pair of nodes. Each Transmitter and Receiver
pair must be configured to operate on the same channel i.e. both devices configured for operation on
channel 1. NOTE: configuring adjacent Node pairs with a channel separation of 11 is not advised
as it may cause interference.
Range
The range function allows a number of range values to be chosen from a dropdown menu. If the range
falls between two values use the larger value. For range above 100M set range to 100M.
Algorithm
The algorithm setting allows the user to choose which algorithm is best suited to their enviornment.
Three algorithms are currently available to users. The algorithms and their best use case are described
in this section. A drop down menu is available on the configuration utility to allow users to select the
algorithm they wish to use see Error! Reference source not found..
Installation Manual

HALO
Installation Procedure
Figure 19: Configuration Utility Algorithm Settings
Algorithm A
This algorithm uses a digital sensing technique and offers “detect all” capability. Using this algorithm it
is possible to configure the sensitivity to reject certain events such as small animals or parallel motion.
Using Algorithm A on a high sensitivity level it is possible that certain foliage movements and small
animals may result in an alarm event. This algorithm is suitable for those users who operate a sterile
environment and wish to be alerted to EVERY event.
Algorithm B
Algorithm B is based upon extensive research and data analysis and is designed to offer the optimum
rejection of fast moving objects such as small animals, thrown objects and birds. This algorithm works
by extracting certain frequency components of the signal which are known to occur during deliberate
intrusions but do not occur as a result of a fast moving small object. This algorithm offers the user the
ability to detect all walking and running intruders while not raising an alarm when someone throws an
object through the beam or when a bird flies through. This algorithm will also offer the user the ability
to raise an alarm if a person is walking parallel to the link within the beam. This algorithm is best used
in an environment where small animals result in false alarms.
Algorithm C
Algorithm C combines numerous digital signal analysis techniques to offer the highest degree of
intelligence. Algorithm C offers the user the ability to raise an alarm due to a crawling, walking or
running intrusion while not raising an alarm due to foliage movement, small animals or parallel motion.
This algorithm is suited to environments where foliage encroaches on the detection zone.
Installation Manual
25
HALO
Installation Procedure
Sensitivity
The sensitivity of the device is software adjustable. As each 100M zone of a site may vary this allows the
user to configure the system due to the unique conditions of the area. There are 8 sensitivity settings
available for each algorithm A, B and C. For devices configured as a Transmitter this function does not
change the operation of the device. For devices configured as a Receiver the sensitivity settings will
change the operation of the device. Sensitivity 0 is the least sensitive setting and Sensitivity 7 is the
most sensitive setting.
Upper and Lower Deadzone Sensitivity
The HALO device is optionally fitted with UPPER and LOWER deadzone elimation modules. If the device
is fitted with upper or lower deadzone sensors ensure that the corresponding checkbox is ticked to
ensure that deadzone detection is enabled and will trigger a relay if required. See Figure 20.
The sensitivity setting of the deadzones can be altered using the configuration utility. Sensitivity 5 is the
default and is appropriate for most installations on all surfaces. In some environments false alarms may
occur and thus the sensitivity setting can be altered to counteract the false alarms.
NOTE: In the event of reconfiguration of the deadzone sensitivity ensure that the area around the
deadzone elimation module is kept clear for a period of 10s to ensure it recalibrates to its correct setting.
Figure 20: Configuration Utility Deadzone Settings
Installation Manual

HALO
Installation Procedure
Relay
There are two software configurable relays on the HALO board. Each relay can be configured in 4 unique
modes see Table 7.
Table 7: Relay Modes
Mode
Description
Disabled
Relay is set to the NC position
Normally OFF
Relay is set to the NC position, in the event of an alarm the relay is set to
the NO position for a defined duration
Normally ON
Relay is set to the NO position, in the event of an alarm the relay is set to
the NC position for a defined duration
Enabled
Relay is set to the NO position
Duration
The relays remain in an alarm state for a number of seconds depending on the duration setting. This
allows users the option to control the length of time a peripheral device is activated by triggering the
relay for a user defined duration. The duration can be chosen by the user. The duration ranges from 1
second to 30 seconds in 1 second increments. Relay 1 and Relay 2 are independent and can be set to
different durations.
Alarms
The HALO defines 5 different types of Alarm – Intruder, error, tamper, power and environmental.
The checkbox for alarm type must be checked in order to ensure alarms of that type are transmitted. If
the checkbox is not checked no alarms of that type are transmitted. If relay activation is required on
alarm the corresponding checkbox must also be checked.
To ensure that intruder alarms – microwave and deadzone - trigger an alarm the Intruder checkbox MUST
be ticked.
An Intruder alarm is activated if any of the following conditions are met:

A microwave alarm,

Upper deadzone alarm (if fitted and enabled)

Lower deadzone alarm (if fitted and enabled).
The Tamper alarm is activated if the access panel on the device is removed from the device. The alarm
will trigger once and will not trigger again until the access panel is re-attached to the unit and removed
Installation Manual
27
HALO
Installation Procedure
again. This prevents constant alarm triggering due to one event. Tamper alarms are only active if the
Tamper
checkbox is checked.
Environmental alarms are caused by extreme temperature changes within the enclosure. The device is
rated to operate at temperature range of - 30° to + 65°. If the temperature exceeds these values an
Environmental alarm is triggered. An Environmental alarm will also be triggered if the temperature within
the enclosure varies by ±10°C within an 8 minute period. Environmental alarms are only active if the
Environmental checkbox is ticked.
An Error alarm is generated if no SD card is present or has malfunctioned. The device will operate as
normal however a number of features will be unavailable as listed below.

Configuration settings backup

Alarm history log

Firmware upgrade
An error alarm is also caused if the device suffers an unexpected event and needs to reboot. Following
reboot the user will be notified via an error alarm.
Power alarms are generated following device reconnection following a power outage.
Analog input Settings
There are 4 analog inputs available on the device. They are available on connector X701 see Table 3 for
location and wiring details. External devices can be connected to any of the 4 analog inputs. The inputs
are tolerant up to 12V.
If a TTL High (>2.2V) is registered at the analog input A0 – A4 (See Table 3) for a duration of 1 second
an alarm condition will be determined. To activate an Analog Input the corresponding checkbox must
be enabled in the UI under the admin tab. Over-voltage protection is on the device for voltages > 13V.

pair is functioning correctly. The RSSI (counts) should be approximately 2000 counts and will vary
considerably on a walkthrough event as depicted in Figure 21. To view the live Bistatic Radar graph the
Enable
checkbox must be checked and the receiver unit selected.

Restore Factory Defaults
The HALO can be reset to factory settings at any time using PIN 4 on S1001 (See Table 5). Pin 4 should
be set to the ON position prior to power up to restore device factory defaults. Once powered up ensure
that PIN 4 is switched to the OFF position to ensure that factory defaults are not restored on each
subsequent power cycle.

Verification and Test
8 Verification and Test
To verify and test the installed TX/RX pairs, it is advisable to conduct false alarm testing and a number
of penetration tests.
It is advised to leave the units to “stabilize” and monitor for any false alarms for a minimum period of
10 minutes. Following switch on of the units it is recommended that no movable objects are present
between the TX/RX pairs as this will interfere with initial system self-calibration. The detection zone
should mimic the “real environment” free from intruders during the initial system self-calibration. This
process should take no more than 1 minute.
If false alarms do occur during this period there are number of possible causes.
A possible cause in the absence of an actual intrusion or, conversely, the generation of no alarm in the
event of an actual intrusion may be crosstalk from a nearby TX node.
Below are a number of checks in order to diagnose the problem. Confirm the type of alarm generated:
1.
If the alarm was of type Intruder, Perform checks a, b and c. If the alarm is not of type Intruder
proceed to 2.
a.
Ensure that the TX/RX pair is configured correctly i.e. check that the paired devices are
configured as 1 Tx and 1 Rx.
b. Check that adjacent TX/RX pairs are not on the same channel or have a channel
separation of 11.
c.
Ensure that the area is free from movement.
2.
If alarm is of type Tamper ensure that the access panel is securely fastened. Reset the alarm.
3.
If alarm is of type Environmental confirm that temperature is not exceeding Spec +65°C/-30°C
or that a rapid changing in temperature has not occurred.
It is recommended to perform a number of Penetration tests at varying distances along each link. See
Table 8 as a guide.

Verification and Test
If any of the penetration tests do not result in an alarm the following checks should be performed:
1.
Ensure that the Intruder checkbox is ticked in the admin tab of the control panel
2.
If checking alarms using relays ensure that the relays are configured as Normally ON or
Normally OFF) and that they are wired correctly.
3.
If a 1M or 99M crawl test does not result in an alarm ensure that:

Maintenance
The HALO is designed for outdoor use and thus is subject to a constantly changing environment. To
ensure the continued proper functionality it is important to maintain the area surrounding the system.
Maintain natural features (grass, bushes, tree branches, etc.) within and at the edge of the detection
zone.
Following severe weather (storms, strong winds etc.) Ensure that no objects have entered the detection
zone which may result in false alarms. Also ensure that the position of nodes has not changed due to
the severe weather which may result in reduced system function due to improper alignment etc.
Ensure that all alarms of type Environment are investigated as this alarm type is indicative of a system
fault due to extreme temperature changes and may result in reduced system function
Neglect of maintenance could jeopardize the continued proper functioning of the system.
