SWITCH SETTINGS FOR VARIFOCAL LENS
The high resolution camera with varifocal lens and auto iris is configured at the factory for automatic
exposure.
For manually setting and locking the white balance, place a white background in front of camera and
turn off switch 1.
For gamma correction, switch to accurately reproduce scene brightness; when turned on, y = 0.6, and
when turned off, y = 1.0.
For automatic exposure, turn on switch 7, and then turn on/off switch 3 for AGC, switch 4 for
electronic shutter control, switch 5 for backlight compensation, and switch 6 for flickerless motion.
For manual exposure and to enable auto iris, turn off switch 7; set switch 3 on to increase the gain
by 18 dB; set switches 4, 5, and 6 for the desired shutter speed.
