Hi
I got some new cameras from Amazon.
ANNKE 4 Channel HD 1080P SPOE Security Camera
One of the cameras won't work once it's on the wall. I've took it down a few times now to check it. Once it's down it works fine. I've checked the cat5 cable with a line checker and that's fine. I've just put it back up and once again it's stop working. Just get a blank pitcure? Can anyone help
