Mounting Precautions
• The video door station employs a CCD camera, and
its performance may be affected by bright direct light,
such as strong sunlight, gate light, street or porch light
which shines directly into the camera lens.
• Install the video door station in front of where the
caller will normally stand.
• When outside temperature lowers sharply, after rain,
etc., the inside of the camera may fog up slightly,
causing a blurry picture. This is not a malfunction.
Normal operation will be restored when moisture
evaporates.
