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.
