Tracking sensitivity controls how quickly the IR camera responds to the lanyard's motion. If the presenter
will be relatively close to the camera, sensitivity may need to be increased slightly to ensure accurate
tracking. As the presenter approaches the camera, the lanyard appears larger to the IR camera, and
movements are proportionally larger. The IR camera needs to respond faster so that the presenter does not
move out of the frame.
This adjustment differs from the Speed Scaler adjustment, which controls how quickly the video camera
responds when the IR camera starts moving.
The default value for sensitivity is 0.24 second. Moving the slider to the right increases sensitivity by
reducing the camera's response time. When changing the tracking sensitivity, adjust in increments of 0.02
second.
Adjustments:
n
Increase sensitivity if the presenter stays relatively close to the camera (for example, in a small
classroom) and the tracking camera lags behind the presenter's movements through the room.
n
Decrease sensitivity if the tracking appears jittery or "aggressive."
