PARAMETER VALUE SECURITY
(get/set)
DESCRIPTION
outputsize <WxH> 0/7 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.
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.
nresolution <positive integer> 0/7 How many resolution options in this
video mode.

resolution of each stream in current
video mode.
