There are a couple of reasons that this may be happening, you may not be getting enough power to the IR lights, you could have a dirty or scratched lens, or possibly a malfunctioning IR board.
Here are some solutions to try:
– Wipe off the camera lens with a anti-fog solution or wipe.
– Check the image setting on the monitor to see if that improves the quality.
– Power adapters can go bad, try replacing with a new power adapter.
If none of these solutions bring resolution to the problem, please contact our technical support staff so we can assist you with getting your equipment repaired.
