Most Heshuanglock models let you unlock with your face, your palm or your fingerprint. Here is how they differ, so you know which to set up for each person at home.
3D face recognition
Walk up, look at the lock and the door opens. It is completely hands-free, which is perfect when you are carrying shopping or a child. The lock recognises a face in about 0.5 seconds and reads a 3D shape rather than a flat photo.
Palm vein
Palm vein recognition reads the pattern of veins under the skin of your palm. Hold your hand in front of the sensor, without touching it. Because the pattern sits under the skin, it is not affected by dry or worn fingertips, which makes it a good choice for older family members.
Fingerprint
Fingerprint is fast and familiar. Our locks store 50 or 100 fingerprints depending on the model, and the V-series camera locks hold up to 300 users across fingerprints, passwords and cards. On models such as the A30 and V60, the sensor sits in the handle, so you grip and open in one movement.
Use more than one
You do not have to choose just one. Set up face recognition for adults, palm vein for grandparents, and a temporary password for guests or cleaners. You can manage everyone from the Tuya Smart app.
