4 . Remove the Controller Cap
Remove the controller cap using a coin to make adjustments.
(1) Auto Iris Level Adjustment
User needs to adjust the DC level especially for conditions described below:
¾
If camera is facing a window but is placed in a relatively dark room.
¾
If the subject background is extremely bright or dark.
¾
If brightness of the picture on the monitor is incorrect.
Auto Iris Level
- (counterclockwise): To decrease the contrast
+ (clockwise): To increse the contrast
(2) Function Selection Switch
FL (Flickerless)
If the camera is used with 50Hz fluorescent lighting, flicker may appear on the screen. In this case,
ch should be set to FL position and switched to OFF position under normal lighting.
FL swit
AGC (Auto Gain Control)
Set to AGC position, camera’s sensitivity is automatically increased when level of
ambient light drops. AGC function automatically controls signal gain to a maximum of 28dB.
AES (Auto Electronic Shutter)
Set to OFF mode for auto iris control and AES mode for fixed or manual iris
control (The default is OFF mode, this option is not applicable for units fitted with a DC iris lens)
BLC (Back Light Compensation)
This function set to BLC position, is useful when the camera is facing an object
that has excessive light behind it (Ex.: Camera installed facing the doorway).
(3) IR Distance Adjustment
Installer may use IR adjustment function according to installation conditions. It is suggested that the view angle
should be checked before setting up the IR distance.
Table below is the suggested LED brightness and IR distance adjustment:
