Qleung S851 Smart Door Lock Tuya Wifi Smart Remote Control Fingerprint Password Card Key for Hotels Apartments Offices

Smart locks are tech-integrated devices that replace traditional key-only locks with multiple unlocking methods (biometrics, APP, etc.). They offer security features (alarms, anti-interference), smart management (remote control), and emergency backups. Used in homes, rentals, offices, and hospitals, their main role is to boost access safety, convenience, and efficiency—making them essential for smart living.

• Diversified unlocking: Biometrics (fingerprint), electronic credentials (passwords, APP remote unlock, NFC cards), and emergency mechanical keyholes.
• Residential use: Solves key-related issues (forgetting/losing keys) and secures the elderly/children via remote management.
• Rental market: Landlords manage tenants with temporary passwords (no in-person key handover)
