Pan Tilt Joystick widget
The Pan Tilt Joystick widget is available in the videoDriver palette and is intended for use on touch screen systems that support dragging. You can drag it directly from the palette onto a Px page, as shown in Figure 29 Pan Tilt Joystick widget, and then drag the widget boundaries to adjust the layout size and position to fit directly over the video display.
NOTE: In NiagaraAX-3.4 and later versions this widget supports Enterprise Video functions, if it is licensed for the ‟remoteVideo” feature.

After binding the widget to a camera component, you have a transparent control overlay that allows you to pan, tilt, and zoom the camera at three speeds: Slow(>), Medium (>>), and Fast (>>>) by dragging the mouse across the display.
NOTE: Camera controls do not operate unless they are Enabled. Each of these controls must be enabled by selecting the option box for each control under the PTZ Support property on the camera property sheet. The default setting for these controls is Disabled (or, not selected).
See Figure 23 Video Playback controls and indicators and Types of Video View controls and indicators for a description of the controls and indicators associated with this widget. For a description of the Pan Tilt Joystick widget properties, see Common videoDriver widget properties.
