    3. On the captured video image, specify set the detection area using the mouse. To do that, set specify the nodal points nodes of the area of interest using the left mouse button. Area polygon that restricts it. The area is considered to be specified when the last nodal point is consisted consistent with the first one. It is possible to You can add only one area. When attempting you try to add the second area, the first one will be is deleted. After you add an area specifying, the remaining part of the video image will be is darkened.

    14. In the Number of people in crowd field, specify the minimum number of people moving in the direction of a crowd in which the
      15. detection should trigger
    15. detector must generate an event. The default value
      16. is
    16. is 4.
    17. Set the Against crowd direction switch to the position

    19. object movement against a crowd on the video image: Up or Down.
    20. In the Frames 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. the detector processes in the range 0.016–100. The higher the value, the more accurate accurately the detection tool detector works, but the higher the load on the CPU load.
  7. Click the OK button.

Configuring the Detection detection of moving against crowd flow module is complete.
