Different devices have different exposure modes; please refer to the
actual interface.
It includes the following options:
Auto: It can auto adjust the image brightness according to the
environment.
Shutter priority: The device can auto adjust according to the shutter
range which is set by priority during normal exposure range according to
the different scene brightness. The device will auto adjust shutter value
if the image brightness fails to reach the effect and the shutter value has
reached to upper limit or lower limit, which is to make the image reach
the best brightness.
Iris priority: Iris value is fixed, the device can auto adjust the shutter
value if the image brightness fails to reach effect and the shutter value
has reached the upper limit or lower limit, the device can auto adjust the
gain value to make the image reach the best brightness.
Gain priority: The device can auto adjust according to the gain range
which is set by priority during normal exposure range according to the
different scene brightness. The device will auto adjust shutter value if
