Hello Everyone, Please do bear with me as i have not installed a large system like this before. I have 20 dome camera's on all floors of the hotel, all cables are run down to the basement comms room. At first, i made the mistake by connecting the power via terminal blocks & then realised a better option would be to crimp the wires with the "Krimps". Apart from that, around 18 of the camera's are working, all hooked up to the DVR and network. In the comms room i am using seperate power supplies which the power is cherryed off from each supply (max of 5) On one of the cameras, in this case (fire exit) if i disconnect this from the power another 3 camera's will turn off. I just can't work out why, is it because they are feeding from that power? My other problem is the white fuzzy lines & ghosing, not seen so much on the main monitor but more on the computer screen (networked), but the lines are still on the monitor. There are a few floors that are still left to crimp, so im just guessing at the moment the problem is the power on the cameras that have not been crimped yet? Any help would be fantastic. Thank You

Ok, Im sure ill get there eventually. I always accept a challenge in business! When your brain has cooled down, maybe after a beer? lol it would be great to try a few things you suggest. Thanks Again.

Hi, thanks for your reply. Today i purchased an 18ch power unit, not just for the problem i was having but organisation. I did think this would help the situation, but the problem is still the same. If there is a grounding problem via the coax, would you advice i take the dome camera's down and check them individually to make sure no wires are touching anything they shouldnt be? The wires run are siamese, and the coaxial is shielded. Would this kind of problem occur if the shield around the coax gets slightly attached to the coax it's self? If this is not the case, could you suggest anything and everything i could try? The client at the moment is not aware! so i have a good week on my hands. Thank You for your reply.
