@joslinm1 It’s nothing to be concerned about honestly. If you search the forums using the magnifying glass top right, you will find plenty of videos like this by other users. I see these type of dust particles and small bugs or gnats flying by IR lights on the camera all the time. Perfectly normal. The IR lights will reflect off the dust particles making them look much larger than they actually are. I had a very small moth fly by my cam and it looked like a white monster going by. Lol Some think they are ghosts or an orb visitation from another planet. Heat vents near a cam will produce a ton dust particles flying by.
