DESCRIPTION
The visible area of full scene in this video mode.
The unit is pixel in source.
* This value must <= "capability_videoin_c<n>_maxsize"
* If "effectivepixel"<"capability_videoin_c<n>_maxsize",
then the visible area is located at the center of full scene.
The output size of source, equal to the captured size by
device, in this video mode. The unit is pixel.
This value is used as a basic coordinate system for many
features, like ePTZ, privacy mask, motion, etc.
* Source (most for image sensor) may perform scale or
binning, etc on image data, and output data with smaller
size. This parameter is designed to represent this.
Indicate binning is used or not in this video mode.
0: No binning
1: 2x2 binning
3: 3x3 binning
* Binning is a technology to increase light sensitivity by
combining multiple pixels to one. The drawback is
reduced resolution. We design this parameter to disclose
this information.
How many resolution options in this video mode.
Resolution options in this video mode.
The last one is the maximum resolution in this video
mode.
* The element number is defined as "nresolution" in this
group.
