This parameter is available only when you set Exposure
mode to Manual exposure or Aperture priority. The
default value is F1.4.
This parameter is available only when you set Exposure
mode to Auto exposure, Shutter priority, or Aperture
priority.
The gain limit function is used to restrict the upper limit
of the Automatic Gain Control (AGC).
l In the case of low illumination conditions, the AGC

This parameter is available only when you set Exposure
mode to Manual exposure. The default value is 0.
This function is used to increase the image visibility in
poor weather conditions such as rain, fog, and smog. A
higher defogging level indicates clearer images.
However, a too high level will lead to image distortion.
You can set the defogging level based on the site
requirements. The default value is Off.
This function is used to compensate image jitter
reversely to stabilize images when the IPC is subject to
vibrations, while some images may be lost.
You can set Stabilizer factor and Equivalent focal
length only when you set Electronic Stabilizer to
Enable. The default value is Disable.
l Stabilizer factor: A larger value indicates better
l Equivalent focal length: Equivalent focal length is
