> 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?
