Description
Mode
Set the exposure modes. You can select Auto, Manual, Aperture
Priority, Shutter Priority, or Gain Priority. The Auto mode is selected by
default.
● Auto: Exposure is automatically adjusted according to scene
brightness if the overall brightness of images is in the normal
exposure range.
● Manual: You can adjust the Gain, Shutter, and Iris value manually.
● Aperture Priority: You can set the iris to a fixed value, and the Device
adjusts shutter value then. If the image brightness is not enough and
the shutter value has reached upper or lower limit, the system adjusts
gain value automatically to ensure the image is at ideal brightness.
● Shutter Priority: You can customize the shutter range. The Device
automatically adjusts the aperture and gain according to the scene
brightness.
● Gain Priority: Gain value and exposure compensation value can be
adjusted manually.

AE Recovery
Automatic exposure is an automated digital camera system that adjusts
the aperture and shutter speed, based on the external lighting conditions

exposure mode will be restored to the previous mode after you adjust the
iris value. There are five options: Off, 5Min, 15Min, 1Hour, and 2Hour.
