monitor
As you use your monitor keep the screen clean by wiping it with a microfiber cloth to remove 
fingerprints, dust, etc.

Cameras
When dust and grime builds up on the camera lens and glass, it affects night vision capability. The 
infrared light reflects off of the dust and grime, limiting the camera’s “vision.” Use a microfiber cloth 
to regularly clean the cameras or when night vision video is cloudy or unclear.
