I set up my Security camera system (Amcrest AMDV4M8 with 4 AMC4MBC28P-B) about 2 months ago, and thought everything was going well. I went to review footage last night and discovered it hasn't been recording properly.
Here is a video. https://www.youtube.com/watch?v=DL68LyM6o60
It will show live footage for a few mins to a few hours then all cameras go black and it pops up a message that says encode resolution has changed. I clear the message and the videos will come back eventually but always pop up the same message later.
