
Shutter Speed – The fixed shutter speed is selectable from 1/4 to 1/10000 sec (NTSC) and
1/3 to 1/10000 sec (PAL). Users should select the suitable shutter speed according to the
environmental luminance. The following table lists the options.

Gain – A nominal video signal level is usually 1 volt peak-to-peak for composite video, 0.7
volts for component or RGB video, or 0.3 volts for the chrominance subsection, at which
level a fully saturated picture is transmitted to the acceptor. However, for cases where the
video signal is attenuated, a low-noise, high-gain analog amplifier is built into quality video
processing equipment. This amplifier provides video gain control whereby the video signal
can be boosted or reduced. Dark pictures caused by low level lighting are easily adjusted.
The Gain drop-down menu turns the video gain Off or moves it in steps from 1 to 9.
Click SET when you finish setting the gain.
