Lord_Raiden 0 Posted March 5, 2022 Good day, I have 12 cameras on my home video surveillance system, they run off two power supplies, the one was recently replaced and the 4 cameras that run off this one has horizontal lines moving upwards on the screen. This only happens at night and not during the day. The lines are 4 on a screen at a time. Anyone encounter this problem before and can offer advice? Share this post Link to post Share on other sites

Every time I have encountered this it is because of a faulty power supply or grounding issue. Share this post Link to post Share on other sites
