Uniden UDR444 Owner's Manual: Maintaining Your System; Monitor; Cameras

English owner's manual.
Hide thumbs




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


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.
