Please can someone give me advise. I have a PC with a DVR card installed and 16 cctv cameras connected to it. Normally it works fine but about every 5th day all the cameras go off and the DVR software shows "VIDEO LOSS" on all the channels.But if I plug them in, and view the cameras on a test monitor they are fine.
Then I found that i can restart the computer as many times as i want but the problem persists.
Now here's the funny part: If I unplug the kettle-cord with the main power supply from the PC, and plug it back in and then switch it on, the problem magically dissapears!! And then it works fine for about five days until the cycle repeats itself.
Now I don't know if maybe the pc builds up a static charge over 5 days, and maybe discharges when I unplug the power cord, or what.
PLEASE, DOES ANYONE KNOW WHY THAT HAPPENS?????
