Infrared Interference
-
Just installed an nvr and 4 poe Infared cameras RLK8-410B4-5MP. 2 out of 4 cameras are getting an interference in the top left corner. It looks like cob webs blowing in the wind. Once the infrared is off it stops.

I have had the same issue but it was cobwebs or moth eggs etc on the lense, but during the day I cannot see them on footage. At night the infrared highlights them.
Make sure the lense is properly cleaned. Happens on all my cameras -
Very common problem. I have a camera that's protected fairly well from the rain so I taped a wadded up kleenex on the end of a stick and squirted bug killer on it, and then I wiped it around the metal outside of the camera close to the front. You can just spray around the camera as long as you keep it off the front glass and lens. If you have something like eaves or an awning above the camera, spray there and on the bracket, too. All the spiders have to do is step where it has spray. Good spray lasts at least six months.

I've had success using a flee & tick collar. Fits nicely around my bullet cameras. First one lasted about two months, but it was a smaller size for puppies. Trying an adult size now, which wraps twice around the camera.
