Ten Reasons to Buy
a Network Camera
or what your analog camera vendor won’t tell you
www.axis.com
Focus
10 of the most important
functional differences
between analog
and network cameras
www.axis.com
1 – End to interlace problems
www.axis.com
1 – End to interlace problems
> Interlaced scan
> Each image formed from two interlace fields
> Blurriness from capturing moving objects,
even when connected to a DVR
Progressive scan
Entire image
captured at
one time
Crystal clear
images even
with a high
degree of motion
in the scene
> Benefits
– Superior image quality
– Full image details
– Precise, accurate information

2 – Power over Ethernet increases
savings and reliability
www.axis.com
2 – Power over Ethernet
> Not available
IEEE802.3af
Industry
standard
No need for
power outlet
at camera
location
> Benefits
– Cost savings
– Reliability with centralized power backup
– Simple installation
www.axis.com
2 – Power over Ethernet
Both network cameras with and
without built-in support for PoE
can take advantage of a UPS device

3 – Megapixel resolution
www.axis.com
3 – Megapixel resolution
> Stuck with NTSC/PAL resolution
> 0.4 Megapixel at 4CIF and 0.1 at CIF
> Limited image details
Many resolutions
Different aspect ratios
1 megapixel is 10x the
resolution of CIF,
2 megapixel is 20x!
Digital PTZ
> Benefits
– More details, easy identification
– Digital PTZ, higher reliability and
simultaneous pan/tilt

5 – Integrated PTZ
input/output control
www.axis.com
5 – Integrated PTZ input/output control
> Cabling separate from the video signal
> Costly and cumbersome
PTZ control over
the same network
that transports
the video
PTZ commands
sent over the
IP network
Integrated I/O
can trigger
anything and be
triggered by anything
> Benefits
– Less cabling, cost savings, increased functionality
and integration potential

5 – Integrated PTZ input/output control
Example: Typical I/O use –
integration with alarm
www.axis.com
6 – Integrated audio
www.axis.com
6 – Integrated audio
> Only possible with separate audio lines to
the DVR
Audio captured at
the camera
Synchronized with
the video
Can be integrated into
the same video stream
Two-way audio (duplex,
half duplex, simplex)
> Benefits
– Many possibilities: simplex, half duplex, full duplex
– Synchronized audio and video
– Easy to install, cost savings
www.axis.com
6 – Integrated audio
> Entrance control
– Remote dialog and gate/door control
> Listen in on remote sounds
– Audio surveillance
> Provide audio feedback
to surveillance scenes
Example: Communicate and
open a door remotely

7 – Secure communication
www.axis.com
7 – Secure communication
> No encryption
> No authentication
> Anyone can tap into the video or replace the
signal from a camera with another video signal
Video encryption
Authentication using
encrypted certificates
Authorization: to verify
and approve the identity
of the device
Privacy
> Benefits
– Secure image capture
– Secure transmission
– Evidence trail secured
www.axis.com
7 – Secure communication
> Examples of achieving privacy
– VPN
– SSL/TLS (HTTPS)

8 – Flexible, cost-effective
infrastructure choices
www.axis.com
8 – Flexible, cost-effective infrastructure choices
> Expensive coax, proprietary fiber, wireless
> Distance affects image quality
> Adding power, I/O and audio further complicates
this situation
IP = established,
standardized,
interoperable
Digital images =
no quality reduction
Many streams
transmitted
over the same line
A single network wire =
hundreds of simultaneous
full frame rate video streams
> Benefits
– Image quality, flexibility, scalability, future-proof
– Resulting costs comparatively low

9 – True digital solution
www.axis.com
9 – True digital solution
> With every conversion image quality is lost:
– Analog signal digitized in camera’s DSP
– Digital signal converted back to analog for
transport over coax
– Signal once again digitized at the DVR for
recording
Images digitalized once
Stay digital
No unnecessary
conversions
No image degradation
> Benefits
– Superior image quality

COMPARE
> The cost per channel
> Flexibility and performance
CONSIDER
> Back end applications and storage
> Industry standard, open-system based
servers vs. proprietary hardware like a DVR
> Infrastructure used
– Can it be leveraged for other applications?
