A tour is a group of camera presets, where each preset in a tour is displayed in the Viewer window for a set amount of time before the camera moves to the next preset position. To start a tour for a selected camera, right click in the desired viewer frame, move the mouse to Tour Start in the pop-up menu, and then select the desired tour from the sub-menu. To stop a tour, right click the blank space in the title bar next to the camera name in a viewer window, and select Tour Stop.
To manage the tours of a camera, access the camera's web interface.
If the option is grayed-out, this signifies that no tours are available.
