Configuring the the Detection of moving against crowd flow program module includes setting up the detection area, the configuration parameters, and the detector's characteristics.

1. Go to the settings panel of the Detection of moving against crowd flow object
settings panel

It is possible to

    2. In the Detector sensitivity [0.0, 1.0] field,
 specify
24. 1. specify the detector's sensitivity to detecting moving objects in the area of interest.
Optimal
25. 1. The optimal value of the parameter is selected experimentally by testing the

26. 1. detector for
triggers
27. 1. event generation in the required conditions. The range of values is from 0 to 1. The higher the
detection
28. 1. sensitivity, the greater the probability of false alarms. The less the
detection
29. 1. sensitivity, the greater the probability of missing an event
missing
30. 1. .
    2. In the Number of people in crowd field, specify the minimum number of people moving in the direction of a crowd in which the
detection should trigger
31. 1. detector must generate an event. The default value
is
32. 1. is 4.
    2. Set the Against crowd direction switch to the position

33. 1. corresponding to the
objects
34. 1. object movement against a crowd on the video image: Up or Down.
    2. In theFrames processed per second [0.016, 100] field, set the number of frames per second that
will be processed by the detection tool. The range of values is from 0,016 to 100.
35. 1. the detector processes in the range 0.016–100. The higher the value, the more
accurate
36. 1. accurately the
