if a detected target remains in the monitoring scene for a certain time, the system will count the
target as the background automatically. The greater the value is, the faster the target will be
counted as the background.
Minimum Target Size
The system will filter out the object smaller than the minimum target size.
Displacement Constraint for Target Generation
The higher the value is, the slower the target is generated, and the higher accuracy the analysis
will get.
Optical-axis Movement
Check the function when the target moves in the direction of camera's optical -axis.
When the target is far from the device and the movement is not clear, enable this function to
check the move direction.

triggered continuously until the target disappears.
