Di Triggers - Vivotek SC8131 User Manual

VIVOTEK
The "Include U turn from the the out side" mode applies when in a crowded, confined area,
such as the area near the a bus door. People may gather near the door without leaving
the FOV, while it is still necessary to count the number of people moving In or Out of the
vehicle.
Another applicable scenario is to detect how many people have approached a stand or a
booth in a department store or museum. The management staff will then know the human
traffic near specific hot spots.

DI triggers:

The Flow path count takes effect when a DI is triggered. This applies to the applications in
public transportation. A Digital input signal is connected to a door open/close detector on a
vehicle. When the door opens, the Flow path count starts; when the door closes, the count
stops.
During the transition stage (from open to close), every objects whose current or original
positions appear in a specific area will be counted as "In." Unless an object has passed
through flowpath and already been counted as an "In" count, all objects in the area will be
considered as the effective counts.
