The PTZ panel will prompt. Below are the description of its functions:
1. PTZ control: Click and drag the nudget in the center towards the direction you wish
to move to.
2. Focus: Click on the Focus near and Focus far buttons to adjust camera focus.
3. Home: Click to move the camera lens towards the default home position.
4. Zoom: Use the Zoom in and Zoom out buttons to adjust the camera's zoom ratio.
5. Presets: If you configured preset positions, a list of preset positions will appear.
6. Patrol: If you configured preset positions into a patrolling tour, click on this button
and the camera will proceed with patrolling through preset points.
Note that on a speed dome camera, the farther you pull the nudget away from the
center, the faster the lens moves. This works like speed control.
