Actually, I think there are very high security risks when using G4/G410 in this way. The face recognition of G4/G410 is based on two-dimensional image analysis and can easily be deceived by a single photo or picture. We suggest that this door opening method be limited to opening your yard door, not your home’s entrance or garage door.
The face recognition distance of G4/G410 is optimal within 1 meter, with a recognition speed of milliseconds, and can usually unlock your door lock within 1-2 seconds.
