Smart biometric door lock with video intercom and app control Overview A multifunction smart lock that combines 3D infrared face recognition, semiconductor fingerprint sensing, IC card access, password entry, physical key, and app control. Built for reliable daily use with fast unlocking, antispoof protection, weather resistance, and included emergency power options. Key benefits Multiple convenient unlocking modes: Choose face recognition, fingerprint, password, IC card, key, Tuya app, or video intercom to match household or commercial needs. Fast and accurate biometric access: Semiconductor fingerprint sensor with recognition speed under 0.5 seconds and false acceptance rate below 0.001 percent. Secure antispoofing face ID: Infrared 3D face recognition works in low light and at wide angles, supporting shorter users such as children while preventing unlocking from photos or molds. Remote monitoring and control: Builtin 135degree HD wideangle camera and video doorbell send live images to the indoor screen and app when pressed, allowing remote viewing and unlocking over 2.4 GHz WiFi. Robust and weatherproof: Aluminum alloy construction with IP68 waterproof rating for reliable outdoor installation. Long service life and easy recovery: Rated for over 600,000 unlock cycles, rechargeable lithium battery included, and micro Type C USB interface for emergency power if batteries run low.
