Configuring the VideoIntellect detection of movement in prohibited area software module includes general settings and configuration settings: detection area, configuration parameters and detector characteristics.

General settings

  1. Go to the settings panel of the VideoIntellect detection of movement in prohibited area 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 with a red frame on the Video surveillance monitor when a motion event is generated in the prohibited area (3). The prohibited area is 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.

Select area tab

  1. In the Detection settings window, on the Select area tab, click the Stop video button to pause the video.
  2. To add a new detection zone, click on a free area of the video image (1) and use the mouse to determine its boundaries. The new zone will be added to the list to the right of the video image.
  3. To rename a detection zone, enter a new name in field 2. The new name will appear in the zone label on the video image.
  4. You can change the boundaries of the detection zone using the mouse by clicking on its number in the list on the right, and the number of the selected zone will be highlighted in blue.
  5. To delete a detection zone, click the button to the right of the zone name (3).
  6. To save all changes, click the Apply configuration changes button (4).
  7. To start video playback, click the Start video button (5).

Parameters tab

  1. Go to the Parameters tab of the detection tool settings window. This tab displays the parameters of the used configuration. If you do not need to change the configuration, skip steps 2 and 3 and go to the next tab.
  2. To use custom configuration, click the Load configuration from file button.
  3. In the standard Windows search window that opens, specify the path to the configuration file in JSON format.

Prohibited zone motion detection tab

  1. Go to the Prohibited zone motion detection tab.
  2. In the Sensitivity [0, 1] field, specify the detection tool sensitivity used to detect moving objects in the specified area in the range 0—1 (1). The higher the sensitivity, the less noticeable an object can be detected.
  3. In the Reaction time (s, 0-9999) field, specify the period of time in seconds in the range 0—9999, after which the the alarm event Motion in the specified area is generated on the detection tool (2). The countdown begins from the moment the object enters the detection zone. If there is no movement during the reaction time, the timing stops and the counter is reset to zero.
  4. 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 (3). If people stay in the zone longer than the time threshold specified in the Reaction time (s, 0-9999) field (2), an alarm event is generated on the detection tool.
  5. In the Dead time (sec, 0-9999) field, specify in seconds the time interval in the range 0—9999, during which the repeated event is not generated (4).
  6. In the Head size [0, 1] field, indicate which portion of the video image height is the human head in the range 0—1 (5). The default value is 0.10.
  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 movement in prohibited area object.

Configuration of the VideoIntellect detection of movement in prohibited area software module is completed.
