Ten Reasons to Buy a Network Camera
or what your analog camera vendor won’t tell you

Focus
10 of the most important
functional differences
between analogand network cameras

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
> Benefits – Superior image quality– Full image details– Precise, accurate information
Crystal clearimages evenwith a high
degree of motionin the scene
Entire imagecaptured at
one timeProgressive scan

2 – Power over Ethernet increasessavings and reliability
www.axis.com
2 – Power over Ethernet
> Benefits– Cost savings– Reliability with centralized power backup– Simple installation
> Not available
No need forpower outlet
at cameralocation
Industry standard
IEEE802.3af

2 – Power over Ethernet
Both network cameras with andwithout 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 theresolution of CIF,
2 megapixel is 20x!Digital PTZ
> Benefits– More details, easy identification – Digital PTZ, higher reliability and
simultaneous pan/tilt

4 – Intelligence at the camera level
> Not available
Intelligent video Purpose-built, highlyintegrated hardware
Intelligent features: Built-inVMD, Alarm management,
Image enhancement
Intelligent algorithms:Number plate recognition,
People counting
> Benefits– More details, easy identification – More productive and effective means of surveillance– Event-driven– Scalable systems

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

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
Audio captured atthe camera
Synchronized withthe video
Can be integrated intothe 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
> Only possible with separate audio lines to the DVR
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 andopen 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 usingencrypted certificates
Authorization: to verify and approve the identity
of the devicePrivacy
> 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
> Benefits– Image quality, flexibility, scalability, future-proof– Resulting costs comparatively low
> Expensive coax, proprietary fiber, wireless> Distance affects image quality> Adding power, I/O and audio further complicates
this situation
8 – Flexible, cost-effective infrastructure choices
IP = established,standardized,interoperable
Digital images =no quality reduction
Many streamstransmitted
over the same line
A single network wire =hundreds of simultaneous
full frame rate video streams

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
> Benefits– Superior image quality
Images digitalized once Stay digital
No unnecessaryconversions No image degradation

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?
