I have got a couple of Hikvision POE IP cameras that have stopped working. I suspect that moisture has got into the connector. I was watching a video, and it seems that it is a fairly straightforward job to change the connector. However, am I right in saying that the HickVision POE cameras all use the same wiring? I have got two different types or plugged into the same box. I have two cameras which have packed up. One of them is the HIKVISION IPC-B220 and the other one is a slightly beefier, larger camera. However, they all plug into the box in exactly the same way, so I am going to assume that the connector and wiring is the same
