SWITCH SETTINGS FOR VARIFOCAL LENS

The high resolution camera
with varifocal lens and
auto iris is configured at
the factory for optimal
performance in lighting
conditions where auto iris
is required. It is also
configured with the shutter
speed set at 1/60 (NTSC) or
1/50 (PAL) and AGC set at
6 dB of gain.
To enable automatic exposure
Turn on switch 7, and then turn on/off switch 4
for electronic shutter control, switch 5 for
backlight compensation, and switch 6 for
flickerless motion.
To manually set and lock AWB
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 gain control
Switch 3 On increases gain by 6 dB, and
switch 3 Off increases gain by 18 dB.
CAUTION Do not change the shutter speed
unless you understand how changing the
settings will affect the scene detail.
