FAQ

Q1: Can a face recognition lock be fooled by a photo or video?
A: No. Our smart door locks utilize advanced 3D structured light technology and liveness detection algorithms. Unlike standard 2D cameras, it scans the depth and contours of your face. This means it cannot be spoofed by high-resolution photos, videos, or even 3D masks, ensuring bank-level security for your home.

Q2: Does the facial recognition smart lock work in the dark or low light?
A: Yes, absolutely. The face recognition lock is equipped with an Infrared (IR) camera sensor. This allows the lock to accurately map and identify your face in completely dark environments, poorly lit hallways, or under harsh backlighting, providing seamless entry day or night.

Q3: Will the lock recognize me if I wear glasses, a hat, or heavy makeup?

A: Yes. The AI-powered facial recognition system adapts to your daily changes. It accurately identifies your unique facial structure even if you wear prescription glasses, sunglasses, hats, or different makeup styles. However, heavy face coverings like thick ski masks may require you to use an alternative unlocking method.

Q4: Is my facial data stored in the cloud? Is my privacy secure? 
A: Your privacy is our top priority. All facial biometric data is encrypted and stored locally on the lock's secure built-in chip, not uploaded to the cloud or the internet. This zero-cloud-storage design guarantees that your personal data cannot be hacked or leaked.

Q5: What makes a 3D face unlock door lock better than a fingerprint lock? 
A: A 3D face recognition lock offers completely touchless entry, which is incredibly convenient when your hands are full of groceries or carrying a baby. Additionally, it easily recognizes elderly family members or young children whose fingerprints might be too worn or faint for traditional fingerprint scanners to read reliably.

Q6: What happens if the face scanner fails or the lock runs out of battery?
A: Our face recognition smart locks are multi-modal. If you choose not to use face unlock, or if the battery completely dies, you have multiple backups. You can unlock the door using a PIN code, RFID card, smartphone app, or a traditional mechanical key. There is also an emergency USB-C port to temporarily power the lock from a power bank.

Q7: How many faces can be registered on the face ID smart lock?
A: The lock can securely store up to 50 unique faces and palms (along with 100 PIN codes and 100 RFID cards). This large capacity makes it ideal for large families, rental properties, or small business offices where multiple people need secure, keyless access.

Q8: How long does the battery last on a facial recognition lock?
A: Powered by a high-capacity rechargeable lithium-ion battery, the lock typically lasts for 4 to 6 months on a single charge with average daily use. The accompanying app and the lock itself will issue low-battery warnings well before the battery dies, giving you plenty of time to recharge it.
