About the automatic status detection
function
When this product malfunctions due to exoge-
nous noise, etc. for 30 seconds or more, the
product will automatically reset and will return
to normal state. When the product is reset, ini-
tialization will be carried out as when the power
of the product is turned on. When the product
repeatedly resets, exogenous noise level
around the product may be high and that may
cause malfunction. Contact your dealer for
instructions.
Periodically images on the screen appear
to be distorted
When the camera is installed in a location
where it is subject to small vibrations (for
example, when it is installed near devices that
vibrate), images may appear distorted and
stretched lengthways. This phenomenon is a
characteristic of image pickup devices that use
CMOS sensors and is caused by the relation-
ship between the periodic movements of the
camera and the timing that the image sensor
reads images. This is not a problem with the
camera. To reduce the possibility of this phe-
nomenon occurring, install the camera in a
secure location.
