This is motion detection masking; not privacy masking. Analytics will be disabled in the masked
area. The purpose is to manually define regions that will not generate motion alarms. For example,
this can be helpful to eliminate alarms from a tree or bush moving in the wind or to perform auto
calibration for some scenes.
Configure the parameters in the Properties box to set the area-specific parameters. Once the
parameters are set up properly, scroll down and click the
Save
button.
Analytics Calibration
When turned on, the video analytics provide recognition of moving objects based on size and aspect
ratio: human or vehicle. When Show Tracking is set to All Boxes, a “moving” object will initially be
shown with a box indicating the analytics have determined something is moving but have not yet
classified it or determined if it should be an alarm. The analytics will try to determine if the size and
shape of the moving object matches with the calculated Human, Vehicle, or Object of Interest aspect
ratio.
Use the Calibration Tools to set the classification parameters.

Select Manual for the Calibration mode.
The direction (left or right) for an alarm over a tripwire line is controlled by both the Properties
of each tripwire and the direction in which the line was originally drawn. A direction to the right
is to the right of a person moving from the first point to the second point of the line, etc.
