scorpion 0 Posted May 31, 2007 Your english is good! I wanted to understand your problem more. Are you sure the problem is with the power supply and not with the video cable? If you have a bad power supply then all of the cameras will not have video. Are all of the cameras the same? I ask if 2 are 12 Volt DC and the other 2 might be 24AC cameras? Have you swapped the cameras around to see if they work elsewhere? Share this post Link to post Share on other sites

scorpion 0 Posted June 1, 2007 I need another description for mixing. The two cameras are mixing? If the cameras are mixing then I am thinking that you have two videos on your screen. Do I need to think that mixing is the picture is mixed up? Are there a bunch of horizontal lines? Have you had a chance to move the wires around on the power supply? Can you move the cameras around to verify that they work? Share this post Link to post Share on other sites
rory 0 Posted June 1, 2007 one probably has a bad power board, take one of them off at a time, until the mixing goes away. Then you will know which camera it is. Send it back or buy a new one. Share this post Link to post Share on other sites

scorpion 0 Posted June 19, 2007 I would highly recommend having a technition come out and take a look at this. It may be a voltage adjustment, and you will have to hook up some test equipment to get it set properly. If it is not set properly it may damage your cameras, maybe not right away but it can cause problems later down the road You might try posting a picture.
