Wearing the Tracker cont.
The Back Sensor should lie
flat against the back of the
collar or neck.
The Front Sensor should be
lying flat and centered on the
body, just above chest level.
When the teacher turns around to point to a map, for example, the back sensor
continues to receive the infrared tracking signal from the camera and the
camera will continue to automatically track the teacher's movement.
The Tracking Sensors require a
direct line-of-sight link with the
camera.
You should be careful not to have
hair or clothing covering the
sensors.
