Hello, i know 2 years old post almost. I am having the same issue. The cameras were working fine, had a power outage at my business, and know the camera's are black. i can replay video and see it fine, if im on remote access, i can see live video. but if i look at the monitor conntected to the dvr computer, the video feeds all show up black. the system was 100% working. any info would help thank you
