Lockin S5 Smart Finger Vein Electronic Door Lock (Black)
The brand new and improved "Lockin S5 Finger Vein Smart Lock" combines ultimate security with minimalist aesthetics. It features the classic "U-Shield" design, which has been a bestseller for 5 consecutive years, paired with a top-of-the-line fully automatic push-pull lock body that automatically locks when the door closes, forming the first line of defense for your home security.
The Lockin S5 is equipped with the new generation "three-sided finger vein recognition technology," which expands the recognition area by 3 times, precisely capturing subcutaneous vein images inside the finger. Whether it's worn fingerprints of elderly family members, shallow fingerprints of children, or wet or sweaty hands, it achieves 99.9% rapid and accurate unlocking with "no fear of wet hands, one-touch access."
Security protection has also seen a comprehensive upgrade! It features a built-in high-spec C-grade anti-theft lock cylinder and supports anti-prying alarms, anti-attempted opening alarms, and anti-peep-hole unlocking. It offers 8 flexible unlocking methods, including finger vein, password, NFC card, Bluetooth, and mechanical key. With a large 5000mAh rechargeable lithium battery, it boasts excellent battery life. Furthermore, it can be perfectly integrated into a smart home ecosystem, providing real-time alerts for abnormal access, making it undoubtedly the flagship choice for modern families safeguarding their homes!
