I am almost certain they are tiny spider webs running across the camera. Mine did that too until we removed the spider webs. Of course, they will be right back the next night!
Hey, everyone, I think that is tiny spider webs that go across the camera in the night. We cleaned the area, sprayed AROUND not on the camera, so hopefully the little critters will go away.
I have this same thing. I first noticed it back in Dec 2019 and it happens on and off. I do have porch lights that are on when I see these orbs. I am in the northeast and it's in the 20 & 30's temperature wise. I am suspecting that it may be some kind of insect as the other night I saw an orb with a head & legs on one side of it and it looked like the body part of the insect was the orb. I have to say it is really strange and it seems on the nights that I see them, it goes on for several hours between midnight and 5AM. I might try the insecticide and see if that works.
I have had 4 orbs set off my ring camera which is set to recognize people only. First was on Feb 25, then Feb 26, Mar 2 and Mar 23, 2020. In each case you can see through the orb. Have been a bit weirded out.
