All of my IP cameras are wireless, except one pesky one that just couldn't keep from dropping out (fortunately I had the house wired with cat5 when it was built). Recently I decided it was better to go back to the hardwired route with the security DVR and CCTV cameras. What are you using for a DVR with your IP cameras? I've seen a few hardware solutions for IP-DVRs, and a few Linux/Windows based programs, but have never evaluated them. I'd expect you'd almost certainly be better off building one high performance server-class PC and using that than having a bunch of separate NAS and servers. It's one of the huge advantages of virtualization software like VMWare that you can run a number of virtual servers on one physical host. Allowed me a replace a whole room full of energy-gobbling PCs with one high performance efficient beast.
