Rmany 0 Posted October 21, 2016 Hello! I am in a motel where manager has installed parking lot video cameras--but nothing appears on screen. I asked if it was correctly grounded and he said it has 4 wires and all is attached correctly with no fuses or relays--nothing appears on viewing screen in his office. Is there a coupler or other device that could fail for all cameras to send nothing to monitor? I realize this is scant information to provide you with. Any help at all would be greatly appreciated. Thank you in advance for it! Share this post Link to post Share on other sites
