Good question @SashaB! As you know, the Floodlight Cam has two methods of motion detection, one for the camera and one for lights. The 270 degree field of view for the lights allows for it to catch approaching heat signatures efficiently. This means that sometimes the lights can be triggered by a motion that does not trigger your Floodlight Cam to record.
Check out our help center article on how to best control the lights of your Floodlight Cam. As an important note, the Floodlight Cam lights will turn on for all events, assuming it is dark enough outside. I hope this helps!
