    This system was working OK for at least 1 year and 3 months. 12 cameras most of them with IR. Now all the images are in black and white with green or black lines below the image. I can get some examples if you need Each camera have an independent power supply, with passive balun. We made the next tests with no results. 1. We Connect a new camera with balun and then rg59 at least in 5 ports of the DVR, independent power supply, we have the same images 2. Unplugged the DVR and uninstalled from the rack and plugged into a different power source, tested with the new camera (alone), same result. 3. The voltaje receive in the DVR is OK. Well, what you think?, I think is something with the DVR. thanks in advance
