NOTE
The two virtual fences are in sequential order. An alarm is generated only when a target
crosses virtual fence 1 and then virtual fence 2 within the set maximum passing time.
The double virtual fences are not within any deployment area, therefore, when an alarm is
generated, the trace always exists. Only when the target object moves out of the field of
view, the trace disappears.
Try to draw double virtual fences in the middle, because the recognition of a target takes
time after target appearance on the screen and an alarm is generated only when the
object is recognized to have crossed the double virtual fences.
The double virtual fences which detect person foot as the recognition target cannot be too
short, because short double virtual fences tend to miss targets.
