Track
Object
After Exists
The number of milliseconds for which the object must be detected before it is tracked as an object.Increase this
value to reduce false alarms. In a very wide field of view, this value can be safely increased. In a narrower field of
view, this value must be adjusted with caution and could possibly result in valid persons not being detected if the
value is set too high for the conditions.
Drop
Objects
After Miss-
ing
The number of milliseconds for which a tracked object must be missing before it is no longer tracked.
Object Size
Error
Range Sets the minimum and maximum variation to the person size set in the Perspective Settings.

example lights turning on or off.
