The camera has eight numerical shutter speed
options. The higher the number, the faster the
electronic shutter. Increasing the shutter speed will
lower the amount of light passing through the lens.
The slowest shutter speed setting is 1/60 second
(NTSC) or 1/50 second (PAL).
The fastest shutter speed setting is 1/10000
second.
Note: When you use a NTSC camera in the PAL
system environment, set the shutter speed as
1/100, and the image output will be equal to
the output under the flickerless mode.
Note: When you use a PAL camera in the NTSC
system environment, set the shutter speed as
1/120, and the image output will be equal to
the output under the flickerless mode.
5.3 Gain (Gain Control)
