Before you install the camera, read the safety information in the documentation that accompanies the camera.

For PTZ cameras, the required camera settings vary from camera to camera. Ensure the camera is using the correct settings. You must refer to the documentation that accompanies the camera to find out the settings for that particular camera.

PTZ cameras are supplied without a remote control as you control the camera with the StarLeaf Group Telepresence system.

Camera control for the PTZ camera

The Camera Control tab on the home screen provides you with controls for the PTZ camera.

Camera control on the Group Telepresence 3351:

The near-end camera control allows you to pan, tilt, and zoom your camera. This control is available both in a call and before you make a call. If the far end is using a PTZ camera, you might be able to control it yourself using the far-end camera (their camera) control.

Camera presets are pre-defined camera positions. For example, a pre-defined position that points the camera at the whiteboard, or that changes the camera to a wide-angled view. Select the position you require from the touchscreen controller.

If you have more than one camera attached to the Group Telepresence 3351, the active camera selector allows you to select which camera you want to use.

Camera presets

Camera presets allow you to save up to five pre-defined camera positions. Users can then select these positions from the touchscreen controller.

To create camera presets:

  1. Use the touchscreen controller to move the camera to the required position.
  2. On the StarLeaf Portal, find the Edit room system page for this meeting room system and open the Audio and video settings.
  3. In the Portal, enter a name for the preset and select Save. To move the camera to a preset, select Test. To delete a preset, select Clear.

Active cameras

You can have up to three cameras connected to the GT 3351 but only one camera can be active at a time. You can set up to five preset positions, as described above, across these three cameras. When multiple cameras are connected to the codec, the active camera is selected in the Camera Control tab on the touchscreen controller.

Selecting any of the other cameras in the Camera Control tab makes the one you’ve selected the active camera and, if done while in a call, the video immediately switches to that camera and the configured preset view.

This is especially useful in situations where presets alone are not the ideal solution, for example in very large rooms or rooms with multiple speaker locations. Additional cameras provide better placement and zoom levels compared to using only a single camera for one large space. Presets for each of the cameras should focus on areas within a reasonable distance of that camera, rather than heavily zooming in on another location where a camera could be placed.

As an example, consider an auditorium with audience seating, and a podium with a lectern and a whiteboard. Two cameras are installed in the room:

  • One camera facing the podium
  • One camera facing the audience

Presets could be configured for these two cameras:

  • One preset called “Lectern”, which would activate the podium-facing camera and position it to frame the lectern
  • One preset called “Whiteboard”, which would activate the podium-facing camera and position it to frame the whiteboard
  • One preset called “Audience”, which would activate the audience-facing camera and position it to take a wide shot of the audience

These presets allow you to quickly switch between any of those predefined positions for the two connected cameras.
