The AI Fingerprint Unlock feature provides fast fingerprint recognition through AI chips, unlocking the door in just 0.3 seconds with an impressive 99.8% accuracy. To further enhance security, the Anti-peek Keypad adds random numbers to conceal your passwords. The smart lock also offers an Auto Lock function, allowing you to set the lock to automatically engage after a specified period. Additionally, the Backlit Keypad enables easy use in dark environments.

For user management, the lock supports setting one-time passcodes that can be remotely shared with friends, guests, or delivery personnel, so they can access the door without waiting. Permanent codes can be assigned to family members and trusted individuals, while recurring codes can be set up for employees or cleaners. The lock also allows you to create custom codes valid for a designated time.

In case you need to physically lock the door, the internal locking button disables all external unlocking methods. The smart lock is powered by 4AA batteries (not included) and will provide up to 1 year of use before triggering a low battery alarm. Constructed with durable aluminum alloy, the lock is weatherproof and can withstand harsh environments.

Should the smart lock run out of power, you can use emergency backup power by connecting it to a power bank, preventing you from being locked out. The lock also integrates with voice assistants like Alexa and Google Assistant when connected to the Yamiry gateway (sold separately).

When paired with the Yamiry gateway, the smart lock can connect to Wi-Fi, allowing you to receive real-time notifications on your phone every time the door is unlocked, and view the access logs to monitor who has entered. This remote access feature also enables you to control the lock from anywhere, at any time.

For added security, the lock's aluminum alloy construction provides high hardness and corrosion resistance, effectively deterring external damage. The deadlocking system ensures the locks can only be opened from the interior, giving you and your family peace of mind.

Installation is a breeze, with the lock being compatible with most standard American doors and requiring only a screwdriver. The accompanying app makes programming the lock's features effortless, allowing you to enjoy a seamless smart home experience.
