People Only Mode at night

I have a Ring Pro that I keep in People only mode. During the day, pretty good. At night, horrible!! Rarely does it trigger if someone leaves or comes through the front door. Recently had some issues and the camera did not trigger when someone left something on my front stairs at night. I would hate to switch back to regular sensitivity, because that picks up almost everything, including bugs flying in front of it. I did switch on the color night mode, but that didn't seem to help. Anyone have any thought?? Thanks for the help...
