When successfully registered, the speaker plays an audio message, confirming that the registration succeeded. Two messages
(“Registration Successful” and “USERNAME added”) appear in green. The number of registered users increases by one and the
user name shown on the screen is automatically assigned to the newly registered face.
Figure 9. Successful registration
New faces can be added and usernames can be modified through the command-line interface or the phone app
described in the following sections.
NOTE
If your face fails to register due to the registration being canceled, timing out, or due to an attempt to register the same face twice,
the speaker plays an error message and the screen displays a message in red, as shown in
Figure 10. Registration failed
To retry, press and release the SW3 button again.
If you have trouble successfully registering a face, try adjusting the proximity to the camera (either closer or further
away) or move your head left-right and up-down so that the camera can get a better view of different angles of your
face. For more information, see
.
NOTE
When a face is registered, the 3D Smart Lock solution can automatically recognize your face. When a face is recognized, the
screen displays the “Recognition Successful” message in green, the lock icon in the bottom left corner turns from red/locked to
green/unlocked, and the speaker plays an audio message, confirming that a face is successfully recognized.
