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 nugget away
from the center, the faster the lens moves. This works like speed control.
