    CCTV Camera power supply

    Hi to all, I now have my camera on the bench, set up with a 20 meter RG59 cable, with a 12 volt 10 Amp supply to the camera. There is a separate supply to the DVR. I get a very good clear daylight picture but when you cover the IR sensor the screen fades and goes blank. I seem to have run out of options with the cable supply, could the problem be with the settings on the DVR?

    Regarding the cable diameter or gauge what is it FOR a 12 VOLT supply on a R59 CABLE

    All three cameras are identical and I can confirm working in situ before being removed by me. I take your point about Maplins but would say a 1 amp camera, as is the spec for the camera type I have, shouldn't be a problem. But will upgrade to a better power supply if the 10 amp transformer doesn't do the trick.

    Camera tested at the same time as cable purchased. Explained problem to the supplier and they tested the camera and had the same problem. Ok attached directly to a 12 v 2 amp supply but dropped out on infrared on a 10 meter cable. As to the problem being with this camera, 2 others exhibit the same problem. I appreciate you staying with me on this problem.

    Many thanks for the advise. I have now purchased from a reputable supplier Maplin (UK) a 20 meter cable video/power. The camera has been identified as a Cam888 which I believe is a Sony HQ1 RCD 530 TVL Still using this professional lead the camera drops out when using infrared. If 12 v 5 amp power transformer is connected to the camera directly (within a meter) there is no lose of picture. Once the 20 meter lead is connected up the infrared picture drops out. I am going to try using 10 amp supply as soon as it arrives to see if this will overcome what seems to be a power loss, even though I am reliable informed should not happen!

    I now have the camera up and running in daylight but not at night (lamps are on) using 12v with 5 Amps transformer. As it would seem increasing the amps has worked, how high can I can I go with the amperage without damaging a standard camera?

    No I haven't tested the voltage with the camera plugged in as the cable is connected with sealed connections. The voltage cable is between 2-3 mm and described when purchased as miniature cable?

    Many thanks for the help. 2 Cameras checked out OK locally, voltage checked from transformer at 12.25 v and on the end of a second (just in case the first was faulty) 20 meter cable at camera end same voltage. Cameras work OK on short cable straight from a transformer (1 meter) but not on a 20 meter length. Issue seems to be with the 12 v supply on 20 meter cable, but I do not understand why when the voltage is good?

    CCTV Camera power supply

    Hi all, I have a problem with the power supply to a standard 12v IR camera. I have tried 0.5 amp and 1.0 Amp 12v transformers without success. Having purchased specific 20 meter cable for CCTV cameras online and the transformers for the supply to the camera I cannot get the camera to work on the cable supplied . It will work without the cable which presumably is the problem (power loss over the distance) but looking at previous posts 20 meter should not have been a problem. I need help in getting a supply to the camera that will work. Or at least being able to understand what I need to get the system up and running.
