default size of video window when users first connect to Video Server. "Default quality"
option here will be the default quality when users first connect to Video Server. And the
"Modulation" type is auto-detected during initialization, but administrators can still set
it manually. To adjust image settings for best visual quality, press
and a
motion picture window will pop up for your reference. There are four fields including
"Brightness", "Contrast", "Hue" and "Saturation" for video compensation. Each field
has eleven levels ranged from -5 to +5. While adjusting, administrators can click on
to check prior to
the setting in memory. If the adjustment is not good,
administrators can click on
to restore the original settings without change. After
configuration done, click on
to close this window. If parameters are changed
without saving, they will be used until the next system startup.
Maximum frame rate
This limits the maximal refresh frame rate.
Bandwidth utilization limit
Each Video Server can be limited in bandwidth utilization by administrators according to
its priority and importance of location. "Bandwidth limit" is most useful to balance
network utilization when multiple Video Server's are installed in the same network. It is
more effective than changing image quality only and achieves better performance with
adequate image size and quality.
Configure motion detection
The channel can have its own settings of motion detection independently. The settings
including "Object size" and "Sensitivity" allow administrators fine tune to fit into the
environment. The "Object size" decides the space ratio of motioned objects over the
monitored screen. The "Sensitivity" sets the measurable difference between two
sequential images that would indicate motion. The larger object size and lower
sensitivity will make Video Server ignore small variations in images. While the motion
amplitude of some object in the monitored screen is over the settings, a white
M
in red
background will indicate at the upper-right corner of the window.
Motion detection is provided as reference because it is very environment-dependent.
Especially working by the very sensitive settings, some triggered events may be
considered as false alarms though there is tiny difference happening indeed. It can be
affected by florescent light flashing, shadow shifting, and so on.
