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 attached motorized camera
In addition to configuring PTZ camera driver in COM1 or COM2 page, administrators have
to define the relationship between video channel and camera. If there is any PTZ camera
attached, administrators should select the "Camera type" as "PTZ camera", set the
attached COM port and the ID of the PTZ camera. The ID is specific to the camera and
necessary for multiple camera control. Refer to the manual of camera for ID settings.
After clicking on
are up to twenty positions can be memorized. Administrators can move the camera and
then enter the position name and save. The old "Preset position" can also be pulled
down to delete.
The camera control will be activated only when both the attached "COM" port and
"Camera Setting" are correctly configured. The camera ID may be relative to some DIP
switch on the PTZ camera. Administrators may need to read the manual of the PTZ
camera for specific information.
Configure motion detection
Each 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
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
, the preset function will appear in the lower half of window. There
