dahua 5104 video feed went nuts from one camera

last night one camera triggered a spell of about 2 hours of broken video, which had flashes of video from other channels in it, this was from the motion detect playback. then it just returned to normal. is it likely to be a problem with the camera? we did have some rain last night.

could it be a loose connection?

re made the bnc seems ok now.

If the coax is exposed, you might want to wrap it with coax seal or self-fusing tape.
