wind. In order to avoid false alarms, we might want the camera be able to ignore small
motion. The higher is the sensitivity level of the camera, the smaller shift of the object
is needed to trigger the alarm. For example, if the object within motion detection region
has moved for about 1-3 pixels during two video frames, then such small motion will be
discarded by camera if the sensitivity is low, and will still trigger an alarm if the sensitivity
is high. In other words, you can think of sensitivity level as a reversed speed limit
–
the smaller is the sensitivity, the faster are the objects allowed to move without being
detected.
The biggest challenge of motion detection configuration is to find the settings that do
not produce false alarms and at the same time do not miss any actual intrusions. The
rule of thumb is: the sensitivity should be as high as possible while not producing
false alarms. The default sensitivity level of the cameras is 70 (on a scale of 0-100)
and it is a good setting for most standard cases.

to define and adjust
the motion detection region or its parameters. Microsoft Internet Explorer browser is
required to configure the motion detection regions.
There are up to 10 independently configurable motion detection regions. Each motion
detection region has 5 configuration parameters:
Enabled or disabled
Size and shape of the region
Minimum size of the object to be detected
Location of the region
Trigger threshold
Trigger interval
Enabled or disabled
Each region can be enabled and disabled individually. By default,
Region 1 is enabled while the other regions are disabled. Only the
enabled region appears on the video display.
Note that the number of the motion detection region is written
within of the region.
The motion detection area of Region 10 is automatically set as the whole area
outside any of the motion detection regions of 1 to 9.
