I have a 2 camera set up, nothing fancy, just use the motion detection software in the cameras, however for a while I have had a problem with one of the cameras and cannot work it out. Here is a screenshot of the image:
This only happens at night. At first I thought it was moisture so I dismantled and cleaned everything, made sure everything was closed back tight, but it still happened, so I loosened some of the screws to allow airflow instead, but same thing.
Any ideas? Its not the sensor as daytime images are perfect and clear.
3PM Dome Zoom Camera, pretty sure its a IPC-HDBW2300R-Z.
