Note
• A single virtual fence is not within any deployment area, therefore, when an alarm is generated, the trace
always exists. Only when the target object moves out of the eld of view, the trace disappears.
• Try to draw the single virtual fence in the middle, because the recognion of a target takes me aer
target appearance on the screen and an alarm is generated only when the object is recognized to have
crossed the single virtual fence.
• The single virtual fence which detects human foot as the recognion target cannot be too short, because a
short single virtual fence tends to miss targets.
