- [3-in-1 Keyless Entry & 0.3s Fast Recognition] Say goodbye to fumbling for keys! This smart door knob offers 3 secure unlocking methods: Advanced Fingerprint, Smartphone APP, and Mechanical Key. Featuring an upgraded biometric sensor, it recognizes your fingerprint in just 0.3 seconds with a 99.9% accuracy rate and unlocks in 1 second.
- [3 Versatile Modes for Any Scenario] Customize your door's behavior to fit your life. Choose from Standard Mode (auto-locks upon closing for daily security), Passage Mode (keeps the door unlocked for frequent entry during meetings or moving), or Privacy Mode (disables outside electronic access, perfect for sleeping or alone time).
- [Smart APP Control & Custom Auto-Lock] Take full control via the intuitive mobile app. You can store and manage up to 100 fingerprints for family members, roommates, or employees. Plus, you can easily enable the auto-lock feature and customize the exact time delay before the door locks behind you, giving you total peace of mind.
- [Ultimate Privacy & Security] Designed to protect your personal space. When switched to Privacy Mode, the lock strictly defends against outside intrusion—electronic methods (fingerprint/app) will be temporarily disabled. Only interior operation or an emergency mechanical key can open the door, ensuring absolute safety for bedrooms, hotel rooms, and private offices.
- [Low Battery Alert & Emergency Power] Never worry about getting locked out due to dead batteries. The smart lock features a low battery warning system. In the rare event the batteries die completely, you can easily access the door using the included physical keys or temporarily power the lock via the built-in Type-C emergency charging port with a power bank.
