Xiaomi Smart Door Lock 2 Vein Recognition Edition Specs
Xiaomi equips the lock with advanced vein recognition technology that scans finger vein patterns using near-infrared light. This approach provides a more reliable unlocking method for users with worn fingerprints or skin conditions.
The system targets common fingerprint recognition issues for elderly users and children. The AI-powered algorithm continues to learn over time, improving recognition accuracy. Xiaomi claims the system can recognize a user in less than one second, with a false recognition rate of under 0.0001 percent.
The lock supports a total of 10 unlocking methods. These include AI vein recognition, AI fingerprint recognition, permanent password, one-time password, periodic password, smartphone Bluetooth unlocking, mechanical key, NFC card, and Xiaomi smart devices such as phones, smartwatches, and smart bands.
Xiaomi has added a smart peephole with a 2MP sensor to the indoor unit. The peephole works with an AI-based human detection algorithm that records video if someone lingers near the door. The system supports infrared night vision and full-color recording in low light. The device also comes with a built-in display that allows users to monitor their doorstep in real time.
The lock features Xiaomi’s fully automatic lock body with noise-reduction components. The door locks automatically after closing and unlocks smoothly after successful recognition. Xiaomi uses a C-grade mechanical lock cylinder that resists forced entry and blocks electromagnetic interference.
The device runs on a 5000mAh lithium battery that lasts around four months. Backup power is provided by four AA batteries, extending usage by another six months. If both power sources are depleted, emergency charging is possible through a Type-C port.
The lock integrates with the Mi Home ecosystem over Wi-Fi. Users can monitor lock status remotely and receive tampering alerts through the Mi Home app. The system supports multi-screen linkage with Xiaomi TVs and smart home hubs and works with Xiaomi’s HyperOS for personalized automation.
Xiaomi claims the lock has passed rigorous durability tests, including 150,000 open-close cycles and temperature testing from -10°C to 55°C. The front and rear panels measure 399×76mm, and the lock weighs about 3.86kg.
In related news, Xiaomi recently launched the Mijia High-Speed Hair Dryer Pro featuring Smart Scalp Protection, along with a new washing machine equipped with HyperOS, Blue Oxygen technology, and a slim design.
