We had several security cameras installed around our home which were outdated when TIme-Warner (now a charter company) closed their home security department. I replaced the cameras with some Wyze cameras, cut off part of the network cable (with the power on) and used the PoE injectors I already had. Cameras are monitoring the perimeter of my house again! And I didn't have to redo everything or spend a fortune on new cameras (Wyze cameras are $25 max).
