footage captured from a Ring security camera

This is the 2nd instance of my sister's Ring security camera picking up what appear to be orbs racing in all directions in the dark, some swerving in other directions, obviously unusual in their maneuvers. The first video clip she sent me on Dec. 3 had similar objects buzzing around and there was no snow on the ground then, but on this footage there is snow. These were not observed except on the videos. I suspect they are some form of intelligence rather than random phenomena.
