Cleaning (CLEANING)
This is used for refreshing the electric-mechanical contacts built in the camera. Use this function for
maintenance when the camera has been directed to a specific spot or panned over a specific range
for a long time.
Image Hold (IMAGE HOLD)
The camera picture remains a still image on the monitor screen or until the camera reaches the pre-
set position. This function is useful for surveillance via a local area network.
Camera
(1) Camera Identification (CAMERA ID)
You can use the camera identification to assign a name to the camera. The camera ID consists of up
to 16 alphanumeric characters. You can select whether to have the camera ID displayed on the moni-
tor screen or not. See page 28 for the setting.
(2) Light Control (ALC/MANUAL)
You can select the mode for adjusting the lens iris. There are two modes as follows:
ALC: The lens iris is automatically adjusted according to the brightness of the object.
You can select one of two modes (BLC ON or BLC OFF) of backlight compensation.
Backlight compensation is available for the ALC mode. It eliminates strong background light
which makes the camera picture dark such as a spotlight.
MANUAL: The lens iris is fixed at the value that you have set regardless of the brightness of the
object.
• ALC Mode with BLC ON
An important object in a scene is usually placed in the center of the monitor screen. By the setup,
more photometric weight is given to the center of the screen than to the edge of the screen (where
bright backlight would most likely be located). In such a case, the object at the center of the screen
can be still clearly seen even though the backlight may vary.
See page 30 for the setting.
• ALC Mode with BLC OFF
This mode is effective when a main object in the scene is not located in the center of the screen but a
source of bright light is located near the center of the scene. In this mode, the picture is divided into
48 areas that mask the light to keep the clarity of the picture.
