T
he 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.
binning 0, 1, 3 0/7 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.
