1. Go to the settings panel of the Person location tracker object.
   
2. Set the Show objects on image checkbox, if it is necessary to highlight the detected object with a frame when viewing live video.

3. From the Device drop-down list, select the device on which the neural network will operate. Auto—device is selected automatically: NVIDIA GPU gets the highest priority, followed by Intel GPU, then CPU.
   

   Note
   title Attention!
   We recommend using the GPU. It may take several minutes to launch the algorithm on NVIDIA GPU after you apply the settings. You can use caching to speed up future launches .

    

   (see Optimizing the operation of neural analytics on GPU).

   
   

4. If you want to use a unique neural network, in the Tracking model field, click the button. In the opened standard Windows Explorer window, specify the neural network file. If you leave the field blank, the default networks will be used. They are selected automatically depending on the selected device.

5. 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.

   Note
   title Attention!
   For the scenes with static people, the FPS value must be at least 2. For the scenes with moving people—at least 4. The larger this value, the higher the accuracy of pose detection, but the greater the CPU load. With FPS=1, the accuracy will be no less than 70%. This parameter varies depending on the object speed of movement. To solve typical tasks, FPS value from 3 to 20 is sufficient. Examples: pose detection for moderately moving objects (without sudden movements)—FPS=3; pose detection for moving objects—FPS=12.

   
   

6. In the Track retention time (sec) field, specify the time in seconds in the range from 0.3 to 1000 after which the object track is considered lost. This parameter is useful in situations when one object in the frame temporarily overlaps another.
   

   Info
   title Note
   If an object (track) is close to the frame border, then approximately half the time specified in the Track retention time (sec) field must elapse from the moment the object disappears from the frame until its track is deleted.

7. Click the Click the Settings button. As a result, the Detection settings window will openopens.
   

   1. Click the Stop video button (1) to capture a frame.

   2. Click the Area of interest button (2) and specify the area in which the Person location tracker will operate (3). The specified area will be is highlighted with a red frame.
      

      Info
      title Note
      To delete the selected area, click the button.

      
      

   3. Click the OK button (4) to save the settings of the detection tool.

8. Click the Apply button on the settings panel of the Person location tracker object

9. Configure the Pose detection (see Configuring the Pose detection), the Shooter detection (see Configuring the Shooter detection), or the Handrail grip detection (see Configuring the Handrail grip detection).
