This smart door knob unlocks with a fingerprint, a password, an IC card, a key, or the Tuya mobile app over Bluetooth. It stores up to 100 fingerprints, 100 passwords and 100 IC cards. One IC card can be linked to several smart locks.
Fingerprint, password and IC card data are kept on a local storage card inside the knob, not in the cloud. The larger fingerprint module has a recognition rate of up to 99% and unlocks in 0.5 seconds. Auto-locking engages within 5 seconds after the door closes. Other features include an anti-peeping password, a silent mode, a low battery reminder and a Type-C emergency power supply.
Installation needs no drilling or wiring, only a small screwdriver. The knob works on left and right doors and fits most standard residential wood doors. Video tutorials are available. With an additional Tuya gateway, it can connect to Amazon Alexa, Apple HomeKit, Google Assistant and SmartThings.
