Purpose:
On LENS settings menu and SHUTTER/AGC settings menu, you can
set the value of iris, shutter speed and AGC (Auto Gain Control)
manually to obtain the optimum brightness of the image, or set
them to AUTO mode, which enables the parameters to adjust
automatically according to the changing lighting environment.
Note: If the iris, shutter speed and AGC are all in AUTO mode, in
high luminance environment, auto iris is prior to auto shutter; in
lower luminance, auto shutter is prior to auto iris; Auto AGC only
takes effect in low luminance. Please refer to Section 4.3 for more
details.
