I want to display monitor A with 4 cameras & monitor B with only 3 cameras.
I am using a BNC T-joint to loop the DVR monitor display output to A & B monitor, but my aim is to have 4 cameras in A and only 3 cameras in B.
Is there any solution?
I guess your problem would be cabling issue and how not to break the cables while the door ledge open and close. You have to conseal the cable with a flexi pipe and extent the wiring to the TV display so that all the power and jack are apart from the doorway.
I believe your distance at least be 1.2km apart, could be theres a break in the cat5 cable. Maybe if you have spare pair you may want to try connect and see if the power source still Intermittent.
