The unit is pixel in source.
* If
"effectivepixel"<"capability_videoin_c<n>_max
size", 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.
