1. Selecting Smart Plan 

 

To enable passenger flow, turn on the icon and click

 Save 

Note: An icon turns yellow when enabled; 

 

2. Enabling Rule 

After smart plan selection, enable the corresponding rule by checking

 

StereoNumber .

 

People counting 

 

 

Here are critical configuration parameters: 

 

Sensitivity: The sensitivity in object detection. The higher the value, the more sensitive and the 

higher the detection rate, but at the cost of more false alarms;
