LENS ADJUSTMENT
HINT:
• You can use the MONITOR pin and the ground screw to display
an image on a monitor when setting up the camera; the
surveillance angle and range, the lens focus, etc.
Connect a monitor to the MONITOR pin and to the ground
screw using alligator clip cables.
• When monitoring lighting or other extremely bright objects
(which exceed the maximum required illumination), smearing
may occur in the vertical or horizontal direction (either above
and below the high-brightness object or as a perpendicular
band). In such a case, adjust the angle of illumination and other
factors while observing the monitor.
• If fluorescent lighting is used where the camera is installed, the
object will flicker as a result. This type of phenomenon can be
received by replacing the fluorescent lighting with incandescent
lamps.

This camera has a built-in Day/Night function that automatically
change the mode between color for high luminance situations such
as during the day and black-and-white for low luminance situations
such as at night. This allows the camera to be used in a wide
range of luminance conditions.
This switch is used to set the timing for automatic switching
between the color screen and the black-and-white screen based
on surrounding brightness.

The color screen will be displayed first of all when the power is
turned on.
Note:
• When switching between color and black-and-white screens
automatically, it is normal for movement of the optical filter to be
heard and for a vertical black band to move across the screen.
• Switching from black-and-white to color may occur if there is a
significant degree of reflection from the object when using
infrared illumination in black-and-white mode. Adjust the
illumination to avoid switching to color mode.
• The focus setting position may differ between color and black-
and-white screens. Carry out adjustment to ensure that the
focus for both screens is in the optimum position.
