35. 10 – Lower total cost of ownership

36. 10 – 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 is 3.4% lower than an analog solution
32 cameras is the break-even, if no infrastructure is previously installed
From cameras, the costs are similar
Always lower total cost for an IP-based system if the infrastructure already exists
Many non-quantifiable advantages for network video
Flexibility, scalability, image quality, future-proof, etc.
