Manual Mode (Fixed Shutter)
Manual Mode opens the iris completely with a fixed gain. Users can select a suitable shutter speed
according to the environmental luminance. The fixed shutter speed is selected from 1 to 1/10000 sec
(NTSC) and 1/1.5 to 1/10000 sec (PAL). Users should select suitable shutter speed according to the
environmental luminance. See following table, which shows all the options.
Click SET when you finish setting the shutter speed.
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 resulting from low level lighting are easily adjusted.
The Gain drop-down menu enables controlling the video gain from Off or in steps from 1 to 9.
Click SET when you finish setting the gain.
