Review Floodlight activity

Is there a way to see why the floodlights came on, when there was not motion alert? Wondering if someone has hacked into cameras and is turning on the lights someohow. No video loged for the time. For instance I woke up around 1:30 in the morning, our side floodlight came on for about a minute or so, no alert or video log for the that time and that camera.Thank you
