I set up a couple of reolink camera's and have caught what I suspect to be drug dealing and drops. I've noticed I don't see video at certain times at night or notice something and wonder why the motion detection caught someone leaving but not coming.

I set the motion detection after the first night over a tree because it would set off the the motion detection when it moved. Ever since I miss so much activity overnight, check the settings and the blue area (to block out motion) will be covering most of the screen. What is going on? Is there a way to reset the motion detection?
