Smart Door Lock with Palmar and Facial Recognition

Transparent biometric access for the whole household: This smart door lock supports dual biometric authentication via palmar vein and face recognition, with a capacity of up to 50 users – ideal for larger families. Just get close to the door and the lock identifies your palm at a distance of 10-20cm or your face 30-50cm, allowing for contactless and effortless entry. Automatic lock with door sensor and interior lock for peace of mind: For safety, the built-in door sensor automatically activates the lock as soon as the door closes, without any manual action. At night, an additional one-touch lock button on the inner side activates the mechanical lock for added protection. The smart door lock also incorporates a doorbell that emits a clear "Ding‑Dong" chime when pressed, eliminating the need for a separate doorbell system. Built-in doorbell and simple on-device setup, setup is easy. Go to the installation menu, choose the direction of the motor (front/back) according to the door opening (left/right). In the doorbell settings, adjust the volume to your liking. Follow the on-screen instructions to register the primary administrator (it is recommended to register a palmar or facial vein profile first). With admin rights, add more family accesses: palmar veins, faces, fingerprints, PIN codes or badges – and you're done. Smart Wi‑Fi connectivity and control via the Tuya app: When it comes to smart connectivity, the smart door lock supports wireless functionality and is compatible with an optional 2.4GHz WiFi module (5GHz is not supported). Once connected via the Tuya Smart app, you can receive real-time push notifications for all unlock events, remotely unlock the door from anywhere, and perform live video phones and intercoms with visitors – giving you full control at your fingertips, anytime and anywhere. Rechargeable Battery, Type‑C and rugged all conditions: Powered by a high-capacity lithium polymer battery, the smart fingerprint door lock provides everyday reliability. The Type-C port allows for fast charging; in case of low battery, plug in an external battery for emergency access – never blocked again. Built-in alerts inform you in advance. Withstands temperatures from -20°C to 158°F and 80%RH with consistent performance in rain, heat or cold – year-round reliability in any climate.
