  1. Go to the settings panel of the VideoIntellect detection of prohibited direction object, which is created on the basis of the Camera object on the Hardware tab of the System settings dialog box.
  2. In the Frames processed per second [0.016, 100] field, enter the number of frames per second that the detection tool will process (1). With a minimum value of 0.016, the video image will be analyzed once per minute, with a maximum value of 100—once every one hundredth of a second. The default value is 30.
  3. Set the Use GPU checkbox if it is necessary to use a graphics processor (GPU) when working with a neural network.
  4. Set the Show objects on image checkbox if it is necessary to highlight the detection area zones with a red frame on the Video surveillance monitor when a motion event is generated in the prohibited area direction (3). The prohibited area is detection zones are specified in the detection tool settings on the Select area tab.
  5. Click the Configuration setup button (4). As a result, the detection tool setup window will open in which you can define the detection zone and the prohibited direction of movement.

  1. Go to the Prohibited direction motion detection tab.
  2. In the Minimum number of people [0-, 20] field, specify the number of people in the detection zone in the range 0—20, at which the detection tool starts recording an event (1).

  3. In the Intensity [1-, 50] field, indicate in arbitrary units in the range 1—50 how noticeable the object's movement in the detected zone should be for the detection tool to trigger (2). The default value is 10.

  4. In the Duration [1-, 100] field, indicate in arbitrary units in the range 1—100 the duration of the object’s movement in the prohibited direction (3). It can be useful when analyzing dense passenger flows, when an object making its way in the opposite direction appears in the camera’s FOV only for short time intervals, and the rest of the time is hidden from view by the crowd. The default value is 40.

  5. In the Head size [0-, 1] field, indicate which portion of the video image height is the human head in the range 0—1 (4). In the video stream display area, this parameter is represented by a yellow vertical line. The default value is 0.05.
  6. In the Allowable deviation angle [0-, 180] field, indicate in degrees in the range 0—180 the permissible deviation from the direction of movement specified by the red arrow in the prohibited direction (5). The default value is 45.
  7. Set the Background loading checkbox (6) if it is necessary to load the background of the video image; by default, the checkbox is clear.
  8. Set the Background saving checkbox (7) if it is necessary to save the background of the video image for the period of time specified in the Background saving period field. By default, the checkbox is clear.
  9. In the Background saving period field (8), specify the period of time in seconds during which the background of the video image is saved. The default value is 0.
  10. In the Number of analytics streams field (9), specify the number of video streams that will be used for neural network analytics. The default value is 4.
  11. To save the detection tool settings, click OK.
  12. To save the changes, click the Apply button on the settings panel of the VideoIntellect detection of prohibited direction object.
