Smart Digital Lock Residence combines six authentication methods—fingerprint, PIN, Bluetooth app, mechanical key, temporary PIN, and NFC card—secured by an MJA1 encryption chip. It stores up to 50 users per mode and uses a semiconductor fingerprint sensor with virtual PIN masking to mitigate observation-based attacks. Constructed from aluminum alloy with a stainless steel clutch and C-level cylinder, it withstands 480,000 fingerprint reads, 100,000 handle cycles, and 8,000 N pressure. Operating temperature ranges from -10°C to 55°C, and the lock includes peephole tamper protection while remaining secure even if the external panel is compromised.

Remote access management, usage logs, and temporary code generation are available via Bluetooth connectivity. The system provides local alarms and mobile notifications for failed access attempts, lock-picking, and low battery status. Powered by four AA batteries with a 12-month lifespan under typical use, it also features a USB-C emergency power input. Compatible with wooden and steel doors between 40–120 mm in thickness, and available with both standard and hook-type lock bodies, the X1 offers a robust and secure smart access solution for residential applications.
