GAIN/AGC

AGC Mode

There are two AGC (Automatic Gain Control) modes: auto and off.

In the auto mode, the Spectra II™ and Spectra Lite™ domes automatically adjust the gain– the amount of amplification the camera places on its video information in order 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. For instructions on how to do this, refer to the Auto Iris section. When you close the iris, the AGC will turn back on automatically when the lens iris starts closing.

In the off mode the AGC is off.

To change the AGC mode:

1.Program preset 95 (28 if in 32-preset mode; refer to the Preset Functions section) to access the main menu (refer to the Main Menu Access section). The main menu will appear.

2.If the cursor (>) is not beside Camera, move the joystick up or down to position the cursor beside Camera.

3.Press the Iris Open button to enter the Camera submenu.

4.Move the joystick up or down to position the cursor beside Gain/AGC.

5.Press the Iris Open button to enter the Gain/AGC submenu.

6.Move the joystick up or down to position the cursor beside AGC mode.

7.Press the Iris Open button on your keyboard. A star will appear beside AGC mode and the cursor will move to the right beside the word Auto or Off.

8.Move the joystick up or down to choose between Auto or Off.
