Because the counting rule of Flow path is based on the entering point and the leaving point
of one tracked object and the shape of the flow path scheme, it is important to configure
the flow path rule carefully depending on the monitored scene. The following are the
recommended usage for two common scenarios:
In this common scenario, you may want to count the number of passengers passing this
section of a passageway (aisle). It is recommended to adjust the parallel flow path direction
and make sure that the flow path arrows are covering the popular walking routes. If the
passageway is close to the corner, for example, you could slightly expand the centre angle
of the flow path to cover the route of random turns.
A section of one passageway
In this scenario, the arc angle of the flow path rule should be expanded to cover the
possible passing patterns entering or exiting the monitored door. Besides, flow path should
also be expanded to cover the width of the door. Also, the length of the flow path should be
configured in a proper length. A flow path with a length too short will be very sensitive and
that a length too long length will react slowly.
An exit/entrance/door/elevator
