Guys, my cameras are wired with cat 6, I have 9 logitech alert 700e cameras, these cams are Poe, so I'm replacing them with hikvision cams but I'm using the cat 6 that is already installed and the power adapters from these cameras. Eventually I want sell these cameras (Logitech) and I will need to find a new power adapter that that will transfer data using the power lines or electrical circuit of the house. So the option of using just a 12v adapter won't work. Like I said early I'm using the backbone of the logitech camera system, It has work great for these hikvision cameras, the problem is that is ones of these power adapters goes bad they are hard to find and they are expensive and for this reason, I'm looking for something else that will do the same work as the Logitech power adapter does ( Poe and transfer data using the power lines).
