I have an IPC-T5442T-ZE mounted on the soffit. I would like to mount an IPC-HFW5241E-Z12E next to it to read license plates. Unfortunately, this part of the roof is not accessible to pull another Ethernet cable. So I was wondering if I could mount a small outdoor switch and hook both cameras up to that switch. I have an outlet right next to that area so I could power the switch from that. The question however is if the Ethernet cable will be able to provide enough power for both cameras? Are there any other concerns?
