Video Input Source [1..2] OptimalDefinition Profile
Adjust how rapidly the system will increase the transmitted resolution when increasing the bandwidth.
NOTE: Requires that the Video Input Source Quality is set to Motion.
Normal: Use this setting for normal to poorly lit environment. If the source is a camera with
1920x1080p60, the system will transmit 1920x720p60 at about 2.2Mb/sec and above with this setting
set to normal.
Medium: Requires better than normal and consistent lighting and good quality video inputs. If the source
is a camera with 1920x1080p60, the system will transmit 1920x720p60 at about 1.4Mb/sec and above
with this setting set to medium.
High: Requires good lighting conditions for a good overall experience and good quality video inputs. If
the source is a camera with 1920x1080p60, the system will transmit 1920x720p60 at about 1.1Mb/sec
and above with this setting set to high.

Video Input Source [1..2] OptimalDefinition Threshold60fps
For each video input, this setting tells the system the lowest resolution where it should transmit 60fps. So
for all resolutions lower than this, the maximum transmitted framerate would be 30fps, while above this
resolution 60fps would also be possible, if the available bandwidth is adequate.

Value space:
512_288: Set the threshold to 512x288.
768_448: Set the threshold to 768x448.
1024_576: Set the threshold to 1024x576.
1280_720: Set the threshold to 1280x720.
Never: Do not set a threshold for transmitting 60fps.

Video Input DVI [2] Type
The official DVI standard supports both digital and analog signals. In most cases the default AutoDetect
setting can detect whether the signal is analog RGB or digital. However, in some rare cases when DVI-I
cables are used (these cables can carry both the analog and digital signals) the auto detection fails. This
setting makes it possible to override the AutoDetect and select the correct DVI video input.
Requires user role: USER
Value space: <AutoDetect/Digital/AnalogRGB>
AutoDetect: Set to AutoDetect to automatically detect if the signal is analog RGB or digital.
Digital: Set to Digital to force the DVI video input to Digital when using DVI-I cables with both analog
and digital pins and AutoDetect fails.
AnalogRGB: Set to AnalogRGB to force the DVI video input to AnalogRGB when using DVI-I cables
with both analog and digital pins and AutoDetect fails.
