Actually knowing the topology is important. So that should work as you described it. I envisioned 8 independent transceivers. Using 2 or 3 nano's as bridges with a few cams on each one should be fine. I am actually doing that with 2 nanostations one on 5ghz the other on 2ghz and each has a poe switch connected to 4 cams. This works really well although I am in a rural environment as well and there is no competition for freqs.
