4.4.11.12 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.
4.4.11.13 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.
4.4.11.14 Minimum 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.
4.4.11.15 Restore All Default Settings
This button restores ALL VCA settings to their default values. This can be useful if the configuration of a device
is in an unknown state. Note that by default, VCA is switched OFF. Therefore, VCA will need to be re-enabled
if all VCA settings are restored to defaults.
