Ring spotlight cam not recording all events

I have a Ring spotlight cam mounted on my garage wall overlooking our cars, often it will not pick up and record us walking to and from the car. 1 video clip the car is there and the next it is gone with no recording of it leaving or arriving back home, it seems to be able to pick up every car that drives down the street. I do have my sensitivity level set high enough for it to detect close movement. The purpose of these is of course to help with crime, if it doesn't record our car being driven away then it kinda defeats the purpose.
