I'd "reset" the camera first by removing AC power and also the battery for a few seconds. Then reconnect the AC power. Then check the camera is working. Then insert the battery again. The Pro 2 will be recording all the time under AC power as it stores 3 seconds of video to show you what happened before the motion activation (Arlo Foresight). This also means that in the dark, the IR illuminators are on all the time.
