Smart Bluetooth Fingerprint Lock for Home and Office Doors with 200 Fingerprint Storage, 90000 Cycle Lifespan, Supports WiFi Gateway Connectivity, Operates on 4 AA Batteries in Black or Silver Finish
Smart Bluetooth Fingerprint Lock with 200-User Capacity and WiFi Connectivity for Home and Office Doors

This smart Bluetooth fingerprint lock provides a modern, keyless entry method for various door types, including wooden doors, room doors, office doors, and apartment doors. Its core function relies on biometric fingerprint recognition, storing up to 200 individual fingerprints to accommodate families, shared accommodations, or small offices. Designed for reliability, it boasts a high admission rate and a very low rejection rate, aiming for consistent access. The lock is built for endurance, with a rated service life of 90,000 unlocking cycles, making it a practical choice for frequently used entrances. Wireless operation is achieved through four standard AA alkaline batteries, and it offers extended functionality via optional WiFi gateway connectivity for integration into broader smart home or building systems.
Technical Performance and Operation

The lock's performance is defined by several key technical specifications that determine its speed, accuracy, and environmental resilience. These metrics ensure it functions effectively as a primary access control point in different settings.
Speed and Accuracy Metrics
The fingerprint scanning process is designed for efficiency, with a scanning time recorded at under 1.5 seconds from presentation to recognition. This facilitates quick entry without significant delay. Accuracy is highlighted by a stated admission rate and a very low rejection rate, though specific comparative data for false acceptance is not provided. The system uses a 1:N comparison method, matching a presented fingerprint against all stored templates in its database of up to 200 entries to grant or deny access.
Environmental Operating Range
To ensure year-round functionality, the lock is specified to operate within a broad temperature range of -20°C to 65°C. This allows for installation in environments subject to cold winters or hot summers. It is also rated to function in humidity levels from 20% to 90%, accommodating both dry and damp climatic conditions without immediate performance degradation, provided installation guidelines are followed.
Power and Connectivity
The device is powered wirelessly by four No.5 (AA) alkaline dry batteries, a common and easily replaceable power source. The product listing also indicates support for a WiFi gateway, which is an optional accessory or feature that enables the lock to connect to a local network. This connectivity allows for potential remote access management, user permission updates, or integration with other smart devices, expanding its utility beyond a standalone fingerprint reader.
Practical Application and Use Cases

This lock is presented as suitable for a range of residential and light commercial door types, offering a upgrade from traditional keyed locks. Its specifications support use in both private and semi-public access scenarios.
Residential and Multi-User Settings
For home use on wooden or apartment doors, the 200-fingerprint capacity comfortably covers an extended family, frequent guests, or domestic staff without the need for physical key distribution. The high cycle life means it can withstand daily use by multiple occupants over several years. The option of WiFi connectivity adds convenience for homeowners who wish to manage access remotely or receive entry notifications.
Office and Professional Environments
In a small office, studio, or shared workspace setting, the lock provides a secure and auditable entry method for employees or authorised personnel. Eliminating key copying and collection improves security administration. The durability rating supports the higher traffic typical of a commercial entrance. The availability in finishes like black or silver allows it to blend with different office aesthetics.
Considerations and Setup

While the lock offers clear advantages in keyless access, practical setup and limitations should be considered based on the provided specifications to ensure it meets user expectations.
Installation and Capacity Planning
The lock is designed for the stated door types, but precise mounting dimensions, door thickness requirements, and included hardware are not specified, which may require verification for compatibility. The 200-user fingerprint capacity is a fixed limit; for larger organisations, this may require careful management or necessitate a different system. The 90,000-cycle lifespan is a manufacturer rating for the locking mechanism itself.
Functionality and System Limits
The core functionality is fingerprint-based entry. The WiFi gateway is listed as an option, implying it may be a separate purchase or a specific model feature. The lock operates on Bluetooth and optional WiFi, not traditional door handle mechanics, so its operation during a complete battery failure scenario is not described. Users should follow the provided guidelines for use within the specified temperature and humidity ranges to maintain performance.
