● The camera uses a special lens. The dis-
tance of the image that appears on the
screen differs from the actual distance.
● In the following cases, it may be difficult to
see the images on the screen, even when
the system is functioning correctly.
• In the dark (e.g. at night).
• If the temperature near the lens is
extremely high or low.
• If water droplets get on the camera, or
when humidity is high (e.g. when it
rains).
• If foreign matter (e.g. snow or mud) get
on the camera lens.
• If the sun or headlights are shining
directly into the camera lens.
• When the camera has scratches or dirt
on it.
• A bright object such as a white wall is
reflected in the mirror surface over the
monitor.
• When the camera is used under fluo-
rescent light, sodium lights, or mercury
lights etc., the lights and the illuminated
areas may appear to flicker.
