For three nights in a row at 2 am, 3 am and 4 am ish it has gone off as “person” and been on at least 2 minutes each time. No one is ever there and nothing is on the video. The camera shows motion, vehicle, animal and person and has never tripped as a person unless an actual person was there. Last night it didn’t didn’t have this happen. Does anyone know why this would happen? It creeped me out.
