Smart Bluetooth Fingerprint Lock for Wooden Doors with 200-User Storage and 90,000-Cycle Life

This smart Bluetooth fingerprint lock presents a practical, keyless security upgrade for interior doors in homes and offices. Designed for straightforward installation on wooden doors, room doors, office doors and apartment doors, it eliminates the need for physical keys by using biometric fingerprint recognition. The core appeal lies in its combination of high capacity, with storage for 200 individual fingerprints, and quick operation, boasting a scanning time of under 1.5 seconds. It is a self-contained unit powered by four standard AA alkaline batteries, requiring no complex wiring, and is built to perform over an extensive 90,000-cycle operational lifespan, offering a reliable access control solution.

Features and Construction

The lock's functionality is defined by several concrete, measurable specifications that ensure consistent performance. It employs a 1:N comparison method for fingerprint verification, matching a scanned print against its entire stored database. The hardware is engineered to withstand varied indoor environments, operating effectively in temperatures from -20℃ to a high of 65℃ and in humidity levels ranging from 20% to 90%. This makes it suitable for most internal domestic and commercial settings without concern for seasonal temperature fluctuations.

Material and Build

The lock's construction, while specific material grades are not listed, is designed to deliver the stated 90,000-cycle operational lifespan. This durability figure indicates a build quality intended for frequent daily use across its application on wooden doors, apartment doors, and office doors. The integration of Bluetooth connectivity allows for user management and setup without the need for a dedicated physical programming interface on the lock itself, simplifying the administration of its 200-fingerprint capacity.

Size and Practical Fit

The lock is designed for application on standard interior wooden doors, room doors, office doors and apartment doors. Its power-independent design, using four AA (No.5) alkaline batteries, means it does not require proximity to a mains power socket, providing greater flexibility in door placement. The absence of stated physical dimensions in the source suggests a design intended to replace or augment existing door hardware within common footprint parameters.

Uses and Placement

This fingerprint lock is specified for use on interior doors, making it ideal for securing private areas within a shared space. Its keyless nature addresses common practical problems like lost keys, the need for multiple key copies, or providing temporary access. The 200-user capacity supports scenarios with many authorised personnel, such as in office environments, small businesses, or large households, without the logistical hassle of key management.

Event or Professional Use

In professional settings like offices, the lock can control access to server rooms, storage closets, or private offices. The high fingerprint capacity allows every employee to have individual access, while the admin can easily add or remove permissions via Bluetooth. For events or short-term rentals, it can provide secure, changeable access to specific rooms without the cost and security risk of cutting and distributing physical keys.

Everyday Home Use

For everyday home use, it offers convenient, keyless entry to the main house, internal rooms like studies or utility rooms, or apartment doors. Family members can register their fingerprints, and the lock's low false rejection rate (under 0.0005%) minimises frustration during entry. It is particularly useful for children who may lose keys or for granting secure access to regular home helpers without needing to hide a key.

Benefits and Buying Value

The value of this lock stems from its combination of high biometric capacity, long operational life, and elimination of physical keys. It solves the practical problem of key management and provides a reusable, durable access control solution. The low false acceptance rate (under 0.004%) offers peace of mind regarding security, while the environmental tolerance ensures year-round reliability indoors.

Reuse and Low Maintenance

The product is defined by its reusability and low maintenance. With a 90,000-cycle lifespan, it is designed for years of daily use without replacement of the core mechanism. Maintenance primarily involves periodically replacing the four AA batteries. There are no consumable keys to replace or cut, and user management is handled digitally via Bluetooth, reducing long-term administrative tasks and costs.

Why Choose This Product

This product is a sound choice for those seeking a keyless entry system with verified performance metrics. Its 200-fingerprint capacity is a concrete advantage over lower-capacity models for multi-user environments. The sub-1.5 second scanning time, supported by the very low rejection and acceptance rates, indicates a system focused on both speed and accuracy. The use of standard AA batteries and lack of wiring requirements make it a practical, installer-friendly option for upgrading existing doors.
