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.
