   It is possible to display the video in a separate window and expand this window to the desired size. To do this, right-click 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.

   
   

5. Click a point on a video image from the stationary camera (on the left). As a result, the X and Y fields are filled with this point coordinates (4).
   
6. Move the PTZ camera so that the green cross in the center of it is centered on the same point as selected on the stationary camera. Use Up, Down, Left and Right buttons to control camera movement, and + and - to zoom in and out (5).
7. Click Request PTZ (6).
8. The PAN, TILT, ZOOM fields are filled with the PTZ camera coordinates (7).
9. Click OK (8). The coordinates are displayed on the Tag & Track object settings panel.
10. Repeat steps 2-8 at least 5 times for different points on the video image. It is recommended to add as much points as possible.
    

11. Click Apply.
    

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