We have a broad client base that prefers Ip network cameras due to their higher resolution and better performance. Ip network cameras are definitely getting very popular these days.

The economics are usually compelling to do so given the value and risk of enterprise data. I doubt that the economics are anywhere near as good for video surveillance - whose value is far less to most enterprises and whose volume can be far higher. “customers are utilizing the WAN for remote replication and disaster recovery”

This has been seen too many times in the past. We've noticed with IP SAN deployments, customers are utilizing the WAN for remote replication and disaster recovery. The main point I'm trying to make is not about the benefits of WAN, I simply highlighted the keys to centralizing your hardware resources via IP.

Are you saying WAN bandwidth prices will drop dramatically? Are you implying that people will become more willing to justify the cost of WAN bandwidth? The business case of paying for WAN bandwidth to eliminate distributed storage costs seems quite weak. Do you have ROI calculations that show the benefit of using the WAN for centralized storage? How will “The demand for centralized storage force the realization paying for WAN bandwidth as a necessity”?

We've seen something a little different.. (1) The demand for centralized storage will force the realization paying for WAN bandwidth as a necessity. In the future the real need vs wishing will be determined by whether or not the expense for bandwidth is spent. The security market will soon follow the IT segment in this regard. (2) Unfortunately, end users will be faced with reduced megapixels, lower FPS or more advanced compression cameras will have to be used if the infrastructure cannot handle the IO. Again demand for resolution will result in 10Gbe becoming the standard, just as in years past 100Mb/s networks were replaced by 1Gbe backbones. Speed will ultimately win our aided by the reduced pricing in 10Gbe hardware components. This has been seen too many times in the past. There was a time when everybody expressed the same concerns about going from 10Mb/s to 100Mb/s. Look at today.. in three years it will be 40Gb/s. John, thanks for your comment.

Now, some may have 10GB in place but many do not or will not want to increase the load on their LANs to the levels needing for high definition IP surveillance. In both of these scenarios, distributed tends to be preferable. While I agree that some applications benefit from centralizing video surveillance, there are 2 major barriers/problems to this:
