min_area filter not working??

[bm55]

I have a zone called "frontDoorA" which has person filter with min_area = 6200. Shouldn't that prevent it from activating the zone when it detects person's area smaller than 6200?

Once an object is part of a zone it remains part of the zone, that filter only applies at the beginning.

So odds are an actual person walked by, activated the zone, then walked inside and this false detection occurred thinking it was the same "person" that never left the frame

@NickM-27 That is likely what happened here - I do see a real person at the beginning of this long video clip. I will re-start frigate, need a better model that doesn't detect shoes as person :)
