  1. Go to the Crowd detection tab.
  2. In the Head size (3-100) field, specify in the range 3-100 what part of the video image height is the human head. The specified fractional value is rounded to an integer value when you switch to another field or save the settings. The default value is 3.

  3. In the Occupancy field, specify as a percentage the share of the detection zone area, which must be filled in order for the detection tool to record the beginning of the Crowd event. If the occupancy remains longer than the time threshold specified in the Reaction time field, a Crowd alarm event is generated on the detection tool. The default value is 50.

  4. In the Reaction time field, specify in seconds the time interval after which a Crowd alarm event is generated on the detection tool if the value of the Occupancy parameter remains equal to or above the set threshold. If during the specified period of time the value of this parameter drops below the threshold value, then the time counting stops and the counter is reset to zero. The default value is 100.

  5. In the Time between alarms field, specify in seconds the frequency of a Crowd alarm event generation. The default value is 180.

  6. Set the Background loading checkbox if it is necessary to load the background of the video image; by default, the checkbox is clear.
  7. Set the Background saving checkbox if it is necessary to save the background of the video image for the period of time specified in the Background saving period (sec) field. By default, the checkbox is clear.
  8. In the Background saving period (sec) field, specify the period of time in seconds during which the background of the video image is saved. The default value is 0.
  9. In the Number of analytics streams field, specify the number of video streams that are used for neural network analytics. The default value is 4.
  10. To save the detection tool settings, click the OK button.
