Lights frequently keep coming on at night.

I have a floodlight cam wired pro model Black - SKU: B08FBRQ7RD. When it's dark the floodlights frequently come on, all night every night, but the camera only records when something is actually detected. Why do the lights keep coming on when there is no motion? something is triggering the lights but not the camera - camera is functioning as expected. Settings lights off, motion detection on, no mode settings, no schedules, motion sensitivity is in the middle, sound detection off, motion-activated lights is on (but assume this is need for the camera).
