I have a group of three cameras all hooked to a Unifi Switch via POE. I also have a WiFi AP and several other cameras hooked to the same switch and they are still working fine. I checked the connections and according to my Unifi app the cameras are present but they refuse to respond. Any suggestions? I believe I have some spare ports available. I unplugged everything and sprayed with DeOxit and resealed the exterior connections. One camera is a PTZ and it goes through it's reset procedure so I believe it's alive.
