User Guide
The default setting has been pre-selected. You can adjust the viewing distance
according to your needs.
Notes:
1. Ensure the lens of the camera is exposed and not covered.
2. Ensure your eyes are exposed 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, the distance detection may be
affected.)
Wear glasses may affect the accuracy of the face image verification.
