The PresenterTrack feature enables the camera to follow a presenter that is moving about on stage. The tracking stops when the presenter leaves the stage. You can set up this feature from the local web interface of the device.
The following cameras and room devices support PresenterTrack:
Codec Plus with PTZ 4K, Precision 60, or SpeakerTrack 60
Codec Pro with PTZ 4K, Precision 60, or SpeakerTrack 60
Room 55 Dual with PTZ 4K or Precision 60 as external camera
Room 70 with PTZ 4K or Precision 60 as external camera
Room 70G2) with PTZ 4K or Precision 60 as external camera
SX80 with Precision 60 or SpeakerTrack 60
MX700 and MX800 with single or dual camera
Capabilities and Limitations
Once set up, you activate and deactivate PresenterTrack from the camera panel on the Touch controller.
The camera uses digital pan, tilt, and zoom, so it doesn’t move physically while tracking the presenter.
PresenterTrack supports the tracking of one or more persons on stage. If they stand too far apart to fit within a zoomed view, the camera zooms out to show the full stage.
You can set up the device to use one of the cameras in a SpeakerTrack 60 camera assembly (or an MX700/MX800 dual camera) for PresenterTrack.
You cannot use PresenterTrack and SpeakerTrack simultaneously. When you activate PresenterTrack, SpeakerTrack is disabled automatically. And also the other way around, when you activate PresenterTrack, SpeakerTrack is disabled automatically.
There is one exception to this: In the Briefing Room and Classroom scenarios both features are active simultaneously in the Q&A mode.
Considerations Before Placing the Camera and Defining the Stage Area and Trigger Zone
When you set up PresenterTrack, you must define a stage area and a trigger zone. Consider the location and use of these areas when placing the camera that is tracking the presenter on stage.
Stage area: The stage area is the zoomed-out overview image.
Make it large enough so that the presenter can move about on stage. The tracking stops when the presenter leaves the stage area.
Allow the audience or meeting participants to move naturally in the room without triggering the tracking.
Trigger zone: Presenter tracking doesn't start before the camera detects a face in the trigger zone.
Choose a location where the presenter naturally enters the stage, for example by a presenter table or podium.
Make it large enough for the camera to detect the face of the presenter.
To avoid a false face detection, make sure that the background of the trigger zone is neutral. Avoid having the trigger zone in front of a screen.
Set Up PresenterTrack for Room Devices
Before you begin
We recommend you to be in the same room as the room device and camera while setting up PresenterTrack.
From the customer view in https://admin.webex.com, go to the Devices page. Click on the device you want to configure. Go to Support and click Web Portal.
If you have set up an Admin or an Integrator user for the device, you can access Advanced Settings directly by opening a web browser and typing in http(s)://<endpoint ip or hostname>.
Check Enable PresenterTrack and click Configure... to open the configuration page.
Opening this page deactivates standby and presenter tracking, enables the self-view in full screen, and shows the trigger zone rectangle on the screen of the device.
Don't leave this web page without clicking Done, otherwise the trigger zone rectangle stays visible on the screen of the device. (Alternatively, tap the Camera icon on the Touch controller and choose a camera position from the list to remove the rectangle.)
Choose a camera from the Camera source drop down list and use the camera controls (zoom, pan, tilt) on the Touch controller to define the stage area.
You see a notification if the camera does not support the PresenterTrack feature.
A blue dashed rectangle, which represents the trigger zone, is shown on the web interface. Move and resize the rectangle while watching the screen of the device. You see the same rectangle overlaying the camera self-view. Place the rectangle where you want the trigger zone to be.
If you want to set up a more advanced polygonal trigger zone, see the Set Up a Polygonal Trigger Zone section.
Tap the Camera icon in the upper right corner of the Touch controller and choose Presenter from the list of camera positions.
This activates presenter tracking.
Position yourself in the trigger zone and see that the camera zooms in on you. Walk about on the stage and check that the camera follows you. Also check that presenter tracking stops when you leave the stage.
If something fails, go back to step 4 or 5 to adjust the size or location of the stage area or the trigger zone.
For more troubleshooting help, you can switch on PresenterTrack diagnostics mode, as described in the Diagnostics Mode section.
Set Up a Polygonal Trigger Zone
You can set up only rectangular trigger zones from the Presenter Tracking web page. If you want to define a more advanced polygonal trigger zone, you must set the configuration (read the Advanced Settings article for information how to access the configurations of the device).
The value of this setting is a string that contains the coordinate pairs of all the vertices of a polygon.
Example: Define the following trigger zone, which has 12 vertices. The diagram shows the coordinates of all the vertices. Such a trigger zone may be convenient if there is a screen, which you want to avoid, behind the presenter.
Starting from the upper left vertex and going clockwise, the corresponding setting value forbecomes:
The PresenterTrack diagnostics mode may be a helpful tool when troubleshooting an issue. In order to set the device in diagnostics mode, you have to use the API of the device. Read the Advanced Settings article for information how to use the API.
The following command sets the device in PresenterTrack diagnostics mode:
xCommand Cameras PresenterTrack Set Mode: Diagnostic
In this mode, you see the stage area (the zoomed-out overview image) on the screen, and an overlay with the following indicators:
RED frame: The trigger zone.
YELLOW frame: The zoomed-in view of the presenter.
GREEN frame: A face that is detected and tracked.
GREEN or RED blinking filled frame: Face detections. Green color indicates a high confidence, red color indicates a low confidence.
BLUE frame: A face that is detected, but not tracked.
