I have several PoE IP webcams installed on my house. Each mounting point has only one wire going to it: the Cat6 with 8P8C plug at the end, which both powers and communicates with the camera.
I would like to ensure that if any device other than the known camera is connected to the port, the attacker won't be able to access the network. What's the best way to do that? I would prefer the solution to be as much hands-off as possible. Thank you so much!
