Infrared Interference

[lunitunz_551449740943604]

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

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.
