AnthDiMatz 0 Posted July 1, 2019 Hi, I am a complete n00b when it comes to this. I believe I have isolated the problem to be a power supply issue. None of my cameras IR are turning on. Cameras worked fine and then randomly turned off. System has ran fine for years. All cameras are off and I have a red question mark on my DVR. DVR HDD has been tested and works. I am assuming there is either a loose connection somehow or a power supply issue. I have a separate power supply box - the LED on the cover is flashing red and if I open the cover the lights flash green. I have not tested the fuses. I am assuming the next step is to do that and then remove each camera one by one from the supply. Any help or advice is appreciated! Share this post Link to post Share on other sites
Benson Chiang 0 Posted January 14, 2020 If all of your cameras have dropped off do not look like they’re getting power I would indeed look at the power supply being the cause. It may be worth testing one of the cameras with a different psu. If it works you’ll have your answer. Share this post Link to post Share on other sites
