4.7.4 Gain/AGC
4.7.4.1 AGC Mode
The three AGC (Automatic Gain Control) modes are auto, on, and off.
• In auto mode, the dome automatically adjusts the gain–the amount of amplifi-
cation the camera places on its video information to obtain a full 1-volt peak-to-
peak video signal out. If the iris is manually opened to its wide-open position
and the picture is weak, the AGC can be turned off and the gain increased
manually to improve the picture. When you close the iris, the AGC turns back
on automatically when the lens iris starts closing.
• In on mode, the AGC is on all the time.
• In off mode, the AGC is off.
To change the AGC mode:
1. On the main menu, move the joystick up or down to position the cursor (>)
beside Camera.
2. Press the Iris Open button to enter the Camera submenu.
3. Move the joystick up or down to position the cursor beside Gain/AGC.
4. Press the Iris Open button to enter the Gain/AGC submenu.
5. Move the joystick up or down to position the cursor beside AGC mode.
6. Press the Iris Open button. The cursor moves to the right beside the word
Auto, On, or Off.
7. Move the joystick up or down to position the cursor beside Auto, On, or Off.
