The Tag&Track function allows a PTZ camera to follow a moving object based on the trajectories obtained by a conventional stationary video camera using the Tracker object. Thus, first create and configure the following objects in the Axxon PSIM software package to use the Tag&Track function:

1. The PTZ camera (see Configuring PTZ IP cameras).
2. Conventional The conventional (stationary) video camera with the Tracker object under it (see Configuring IP devices and Creating and configuring the Tracker object).
   

Configure To configure the Tag&Track as followsfunction, do the following:

1. Create the Tag&Track object under on the basis of the Camera object (not the PTZ onecamera!).
   

   Info
   title Note
   If the camera is linked to a PTZ device, creating a the Tag&Track object will not be available. If you first create this object, then link the camera with to a PTZ device, then the settings for the Tag&Track object will not be available.

3. In the Auto switch field (2), enter the time period in seconds after which you want to automatically switch to the next object in the Automatic Tag&Track mode.

4. Select a line in the table (3). To do that, left-click on any cell in the line.
   

   Info
   title Note
   The lines can be sorted by one of the specified parameters. To do this, click on the name of the corresponding column.

   
   

5. Click the Edit button (4). The Settings dialog box opens.
   If step 3 was is skipped and no line is selected in the table, then the Settings dialog box does will not open and the message appears instead saying "String not selected"«String not selected» will be displayed.
   
   

   Info
   title Note
   For calibration, a video image with a low resolution is used, so the display quality in the Settings window may differ from the original video image from the camera. It is possible to display the video in a separate window and expand this window to the desired required size. To do this, right-click on the video image while holding down the Shift key on the keyboard. The video in the separate window allows the same operations as in the Settings dialog box.

   
   

6. Click on a required point on a the video image from the stationary camera (on the left). As a result, the X and Y fields are filled with this point coordinates (5). The point is highlighted with a red square on the video image with a red square.
   
7. Move Rotate the PTZ camera (on the right) so that the green cross in the center of it is centered on pointed at the same point as selected on the stationary camera. Use the Up, Down, Left and Right buttons to control camera movement, and the + and - buttons to zoom in and out (6).
8. In the Rate field (7), set the movement speed of movement of the PTZ camera lens. Possible values are from 1 to 10, the default value is 1.
9. Click the Request PTZ button (8).
10. The PAN, TILT, ZOOM fields are will be filled with the PTZ camera coordinates (9).
11. If the check is required, then click the Send to PTZ button (10). The camera will be positioned to the obtained coordinates.
12. Click the OK button (11). The coordinates are displayed on the Tag&Track object settings panel.
13. Repeat steps 4-11 at least 5 times for different points on the video image. It is recommended to add as much points as possible.
    

14. Click the Apply button.
    

    Info
    title Note
    When too few points are set, or in some other cases when the points are set in an unsuitable manner not set properly, and the algorithm cannot process them, the corresponding message occurs on clicking Apply saying "Invalid calibration" message is displayed after clicking the Apply button. In this case, click the OK button then add or edit the points.

    
    

Configuring the Tag&Track function is completed.
