Thank you for your replies, I will try the following and report back. Disconnect all the cameras but 1 that currently flickers. then replace that cable with known tested cable and wait till night time and see. In addition to the new cable removing possible ground loop I will also try a separate single camera power supply.. Hope this works

Thanks for the reply, I believe it has the latest firmware..1021-1005-1006-1005

Hello all, new to this forum and was hoping someone could help. I recently purchased an Avtech DVR. I'm having a problem when night time rolls around and the camera's IR is on or it gets dark not really sure. ALL the cameras start to get a frequent flicker like the images attached not at the same time it jumps from channel to channel. Tried another New Avtech DVR same thing. Previous non Avtech DVR had no issues. disconnected all other cameras same issue. i'm stumped. Normal: Flicker: anyhow thanks for anyones imput.
