The OnScreen PTZ mode allows you to control a PTZ camera by mouse manipulations in the Surveillance window.

Click to enable this mode.

In the OnScreen PTZ mode, the Areazoom function is disabled (see Control using Areazoom).

To change the viewing angle, click a video image with the left mouse button and move the mouse pointer in the required direction. During this action, the software displays a visual element on the image showing the camera lens movement direction and speed.

The faster you move the mouse, the higher the speed of camera rotation. 

Click  again to disable the OnScreen PTZ mode.
