I need to correct something here, I was messaged by another forum Maven and my description of what was happening is incorrect. so I tested my camera that I have seen most of my motion on sure that I was right in my description and indeed he was correct and apparently I have a camera that is not working correctly, especially because many of the other cameras behave differently then that one.
so the green motion detection boxes should only be working WITHIN the detection zone you set. so if you have a small detection zone in one area of your frame of view, that is the only area that should detect motion and trigger recording BUT, once it is recording, that entire frame of the video is used for detection of a person. so once triggered even if the person wasn’t in the detection zone, if they were in frame during recording, it should alert for person detection.
and thank you @Newshound for your catch there.
