The Lockin S5 Finger Vein Smart Door Lock adopts the classic U-Shield design, a bestseller for five consecutive years, combined with a premium fully automatic push-pull lock body that locks instantly upon closing, establishing a solid first line of defense for home security. The new generation of three-sided finger vein recognition technology triples the recognition area, allowing for precise capture of subcutaneous vein images. Even if fingerprints are worn down in the elderly, faint in children, or hands are moist, it achieves a 99.9% rapid unlocking experience with a single touch.
The door lock features a high-grade Class C anti-theft lock cylinder and supports multiple alert functions, including anti-prying, anti-tampering, and anti-peep-hole unlocking. It offers eight flexible unlocking methods: finger vein, passcode, NFC card, Bluetooth, and mechanical key. Equipped with a 5000mAh high-capacity rechargeable lithium battery, it delivers outstanding battery life and can be integrated into smart home ecosystems to receive real-time alerts for access anomalies, making it a flagship choice for modern home security.
