Secondly, determine how the camera tracks the presenter.

Use Tracking Sensitivity slider to adjust the sensitivity level of tracking. The current value is
displayed at the upper right corner.

Use Time of Return to Tracking Point slider to define the idle time before the camera returns
to the tracking point. The current value is displayed at the upper right corner.
[Note] The default value of the Tracking Point is preset 1. If preset 1 is not set, the Tracking Point
will be home position.

People Size: Choose to cover the presenter's Full Body or Upper Body while tracking him/her.

Once the Effective Tracking Area is enabled, the camera tracks the presenter only when
he/she is within the specified Effective Tracking Area. When configuring the Effective
Tracking Area, include Preset 10-13 in the Effective Tracking Area so that the camera tracks
to focus on the content of the preset point zone. For instance, in the case where Preset 10 is
excluded from the Effective Tracking Area, even if the presenter walks to the flat TV in Preset
10, the camera will not go to Preset 10 and will not show the content of the flat TV.
