Recorded night videos all have a bright oval-light shaped in 1 spot on video. Light remains fixed.

After a few months using the Arlo, just last week, recorded NIGHT videos all have a bright oval-shaped light in 1 spot on the video. As the video plays, this light remains in a fixed position. I don't see anything on the camera lens (dust, etc).
Thanks

Looks very much like the IR light for night vision is reflecting off something. Compare the nighttime and daytime shots to figure out what it is.

Check for insect eggs on the camera lens. They can be extended with a fine hair about 5mm which can make them invisible in daylight on the video. See image attached of example.
