Q1: What makes Palm Vein Recognition more secure than standard fingerprints?

Palm vein recognition verifies the unique pattern of veins underneath the skin of your palm. Since this pattern is internal and can only be scanned on a living hand, it is virtually impossible to replicate or forge, providing a significantly higher security level than traditional external fingerprints.

Q2: How does the 3D Face Recognition work in dim or dark environments?

The smart lock utilizes an advanced 3D structured light camera alongside infrared sensors. This allows the system to accurately map facial features in real time, enabling reliable hands-free unlocking even in complete darkness.

Q3: Can I manage access permissions remotely via my smartphone?

Yes, the lock supports Tuya APP remote control integration. This allows you to generate temporary access codes, review unlock history, manage user profiles, and receive instant alert notifications wherever you are connected to the internet.

Q4: Is this smart lock suitable for commercial apartments and hotels?

Absolutely. Constructed with high-strength CNC precision engraving, this smart lock is designed to endure high-frequency use. Its versatile credential management makes it an ideal security solution for luxury apartments, boutique hotels, and residential properties alike.

Q5: What happens if the smart lock battery drains completely?

If the battery warning is missed, you can either use the physical mechanical key override or connect a portable power bank to the external emergency USB port to temporarily power up the system and unlock the door.

Q6: What does the two-year free replacement warranty cover?

The warranty covers full hardware replacements for any manufacturing defects or malfunctions occurring within two years of purchase. Please note that shipping fees for returning the defective unit and sending the replacement are not covered under this warranty policy.
