The Xiaomi Smart Door Lock 2 adopts a newly developed fully automatic lock body that has noise-reduction properties. The technology is fully developed by Xiaomi. In comparison to the first-generation models of fully automatic locks, Xiaomi’s self-developed noise-reducing fully automatic locks reduce noise by 12dB when closing the door and 13dB when opening the door. Turning on the Do Not Disturb mode can also turn off the prompt sound and reduce the alarm sound.

Xiaomi also claims that the fingerprint recognition speed is ≤0.5 seconds, the false recognition rate is ≤0.001% and the authenticity rejection rate is ≤0.52%. In addition, users can also pre-set duress fingerprints. If they encounter a crisis, they can use the duress fingerprint function to make a silent call notification to the preset phone number.

Furthermore, the Xiaomi Smart Door Lock 2 is equipped with a MIJIA security chip which allows users to store private data such as fingerprints and passwords in encrypted form locally. In this way, the data cannot be read or decrypted externally. The door lock also supports Bluetooth + Wi-Fi dual protocols. You can remotely view the door lock’s alarm notifications and operation logs through the MIJIA app without using a Bluetooth Mesh gateway device. Users can also share door lock device management rights with family members, making it easier for family members to manage door locks.

In terms of battery life, the door lock is powered by 8 dry batteries and can be used for up to 1 year. It will also remind the user when the battery is low. Peradventure it runs completely out of battery, users can also use the Type-C external power bank to provide an emergency power supply to the door lock to complete temporary unlocking.
