> Benefits Image quality, flexibility, scalability, future-proof Resulting costs comparatively low Standardized fixed and wireless infrastructure
> Expensive coax, proprietary fiber, wireless
> Distance affects image quality
> Adding power, I/O and audio further complicatesthis situation
7Flexible, cost-effective infrastructure choices
IP = established,
standardized, interoperable.Fixed and wireless.
Digital images =
no quality reduction

9 Lower total cost of ownership
Independent study in 2008, based on real RFPs shows that
The total cost to acquire, install, and maintain a 40 camera system is3.4% lower than an analog solution
32 cameras is the break-even, if no infrastructure is previously
installed From 16-32 cameras, the costs are similar
Always lower total cost for an IP-based system if the infrastructurealready exists
Many non-quantifiable advantages for
network video Flexibility, scalability, image quality,
future-proof, etc.
