Face Recognition Smart Lock FAQ

Q: Can facial recognition work in the dark?

A: Many advanced smart locks use infrared or 3D structured light technology, allowing face recognition in low‑light or dark environments.

Q: Can facial recognition work with glasses or hats?

A: Most modern face recognition locks support glasses and hats, but extremely large accessories or masks may reduce recognition accuracy.

Q: Can photos or videos fool facial recognition locks?

A: Advanced face recognition locks commonly use 3D depth sensing or infrared live detection to reduce spoofing risks.

Q: Will sunlight affect facial recognition?

A: Direct sunlight may affect some lower‑end sensors. High‑end 3D face recognition systems are generally more resistant to strong light conditions.

Q: Can children use face recognition locks?

A: Most systems support multiple height ranges, but installation position and camera angle are important for child recognition.
