I have project to put 20 cameras 1 MB/s each for surveillance. I was planing to use one 5Ghz Dual Chain 802.11a/n OmniTik U-5HnD, Router as AP bridge and 20 SXT-5HPnD (or 20 SXT G-5HnD) as a bridge (in bridge mode). 20 cameras will be attached each to 1 SXT. I have 5 buildings with 4 cameras on each corner. All these buildings are in range from 300 meters to 600 meters from the main building. Did anybody have the similar project. Or can anybody comment if this would even work. Any suggestion? Also how should I connect (bridge, wds etc.) what would be the best for this scenario.
connect the client as station wds, and the AP ad AP and dynamic wds enabled. Also have the default bridge-bridge option, and yor AP should work like a big switch.
Careful with the WDS option as mentioned. For each WDS extension, bandwidth capacity gets cut in half. If TLOS is available to each SXT, I would skip the WDS. 20 cameras in WDS could be too much to maintain the throughput you are looking for.
Another option would be to use wireless to connect each building, and then wired to each radio on the building. Bridge all your ports and wireless links and you are good to go [one Omnitik as AP (AP-bridge), all others as CPEs(CPE Bridge)]. The Omnitik has multiple cat-5 ports. 5 Omnitiks should be enough to do everything you are thinking about. This would have far fewer points of failure and should be more effective at managing bandwidth. Another added benefit is the option to use the Omnitik to send power to each camera (assuming cameras are POE IP cameras), and that will cut down your installation cost/headache dramatically. Stick an NVR on the system and you should be in good shape.
[This is based on opinion, not an actual 20 camera setup]
