Three-Sided Finger Vein Recognition
The Lockin S5 uses three-sided finger vein recognition with U-shaped finger pulse technology, reading your vein pattern from multiple angles for a claimed 99.9% accuracy rate — and unlocking in seconds, without the false rejections that can plague a single-angle sensor.
Ways to Unlock
Finger vein, PIN, one-time code, Bluetooth, a mechanical key, and an optional NFC module give you flexible access options for family, guests and deliveries, so no single failure point locks you out.
Battery & Security
A 5000mAh lithium battery keeps the lock running for extended periods between charges, with emergency charging available via a standard power bank if it ever runs low — no need to source a proprietary charger. An ultra-secure C-Class cylinder resists tampering and break-in attempts.
Everyday Convenience
Real-time smart alerts flag lock and door anomalies straight to your phone, an ergonomic U-shield handle keeps daily use smooth and quiet, and integrated night vision with 24G radar supports round-the-clock monitoring. The door auto-locks automatically the moment it closes, so there's nothing further for you to remember.
