I have an 8 camera OOSSXX poe 4k camera system. It records motion just fine during day and will continuous record 24/7 but once it gets dark it doesn’t detect motion at all. I have it set to armed 24/7 and also the motion setting is set to 24/7 . What am i doing wrong ? Ive reached out to OOSSXX numerous times and tried all their recommendations and still my cameras won’t detect any motion at night .
