The Stationary Object Hold-on Time defines the amount of time that an object will be
tracked by the engine once it becomes stationary. Since objects which become stationary
must be "merged" into the scene after some finite time, the tracking engine will forget
about objects that have become stationary after the Stationary Object Hold-on Time. The
default setting is 60 seconds.
Tracking Options
Minimum Tracked Object Size
The Minimum Tracked Object Size defines the size of the smallest object that will be
considered for tracking, in pixels. Normally there is no need to modify this value. Decreasing
it will allow the engine to track smaller objects at the expense of noise immunity.
Display Options
Minimum Alarm Object Display Time
When an alarm is generated, the tracking display displays the object in red. After some time,
the object display fades back to yellow. This setting controls the time the object is displayed
in red, before fading back to yellow. The default value is 2000 milliseconds.
Minium Object Display Time
When an object is tracked by the engine, it is displayed on the tracking display. This setting
controls the minimum time an object is displayed in the tracking display. This is so that
objects that are tracked for a very short time are displayed adequately. The default value is
1000 milliseconds.
Both options affect the web browser display and the burnt-in-annotation.
Detection Point of Tracked objects
For every tracked object, there is a point that we use to determine this object's position, and
decide whether this object triggers a rule. We call this point as detection point. There are 3
modes to define the detection point relative to the object: Default, Centroid and Midbottom.

Default - When user chooses this mode, VCAsys will automatically set the position of
detection point . It chooses centroid if the camera is calibrated overhead, or
midbottom if the camera is calibrated side-on or uncalibrated.

Centroid - If user chooses this mode, VCAsys will force the detection point to be
centroid.

Midbottom - If user chooses this mode, VCAsys will force the detection point to be
midbottom.
