Upgrade your interior entry points with a zinc alloy smart door knob that combines fingerprint recognition, Bluetooth connectivity, and app-controlled digital codes without altering your existing door profile. Engineered exclusively for interior doors measuring 60 mm to 70 mm thick, this unit replaces standard hardware in under ten minutes using only a screwdriver. The integrated mounting template aligns with common residential configurations, eliminating the need for drill bits, shims, or professional locksmith assistance.
Secure access operates through three distinct verification methods. A direct biometric scanner handles routine daily entries, while the numeric keypad employs an anti-peep layout that automatically inserts random digits before and after your primary PIN. To manage visitors, create temporary or single-use passcodes directly within the official Tuya app and revoke permissions instantly once the authorized period ends.
Wireless monitoring keeps you informed without additional wiring. Built-in Bluetooth syncs every locking and unlocking action to the companion application, maintaining detailed real-time access logs and delivering immediate push notifications to your device. The internal mechanism runs on standard dry cell batteries, providing consistent performance for bedrooms, ensuites, home offices, and shared workspaces where running new electrical cables is impractical.
