We just recently bought the Night Owl security system, picture attached, and we noticed they didnt have any type of cover over the camera. Although it may not be "necessary", it's nice to have a cover over the camera in case of rain or snow. Unfortunately, my husband installed it before I could take any pictures, but he said it works….

V1 is if you just want to glue or double side tape it
V2 has an area to also place a zip tie as backup
