The default setting has been pre-selected. You can adjust the viewing distance according to your needs. Note: 1. Ensure the lens of the camera is clearly visible and not covered. 2. Ensure your eyes are clearly visible and not covered. (The function that detects the distance between the user and monitor is based on the position of the user's eyes. Therefore, if the eyes are covered or there is a strong reflection, distance detection may be affected.) Wearing glasses may affect the accuracy of the face image verification. 3. The limits for distance detection by the camera: Minimum distance : approx. 20 centimters (7.90 inches) Maximum distance : approx. 70 centimeters (27.55 inches) Pitch angle (angle of rotation of the face in the vertical plane): Elevation: 20 degrees Depression: 30 degrees Horizontal angle of rotation (angle of rotation of the face in the horizontal plane): between -20 and +20 degrees 3.3 BackOn Track BackOn Track lets you easily back up important files to a disc, hard drive, or other storage device.
