  1. We recently tried to set up some CCTV cameras for our home and everything is fine except that the CCTV video feeds from some of the cameras suffer when we try to simultaneously connect the DVR and cable TV to a Samsung LCD TV monitor. It work's fine if you only connect them one at a time, but the moment you try them both (since we want a TV that's also a CCTV monitor) things just go bad. They're both on separate inputs though, with the DVR on the TV's VGA port and the cable TV connected through (what I think is) a UHF connector so I really don't see a reason for why this should be happening. There's also only one other monitor which is connected only to the DVR through a different DVR output labelled 'Main Out" which uses a BNC connector to connect the DVR to the monitor (the other monitor with problems uses the VGA out). This one is also affected by the drop in quality when we try to connect the cable TV to the other monitor. We've tried several things to try and fix this: We've tested this with different TVs (different brands and types), we've tried completely disconnecting the other monitor attached to the DVR, and we've tried switching out the power supply for the 5 cameras that are affected. All of it doesn't seem to make a difference. Any help or advice would be appreciated. Thank you.
  2. It's actually the RF cable, my mistake. I'm not very familiar with these things. I'm away right now so I'll have to look at that when I get back there. From what I recall both power supplies were two-pronged but I'll have to double check on that. Yes, everything works perfectly when we disconnect the RF cable (for the cable TV?) from the TV.
  3. Will do and thanks for the quick reply. Wikipedia says something about these plugs being dangerous though so I'm assuming that these are just for testing and not a permanent solution. Just some additional information: The cameras are divided in two sets, each with their own power supplies. One set of 5 with a 20 ampere power supply and another set of 3 connected to a 6 ampere power supply. It's only the 5 with the 20 ampere power supply that go wrong when the cable TV is connected. Both sets are physically located pretty far away from each other.
