Smart Bluetooth fingerprint lock with 200 user capacity and WiFi connectivity for secure keyless entry

This smart Bluetooth fingerprint lock provides a modern security solution for residential and commercial doors, eliminating the need for physical keys. It stores up to 200 distinct fingerprints, making it suitable for households, offices, and apartment buildings where multiple users require controlled access. With a scanning time under 1.5 seconds and an unlocking capability exceeding 9,000 cycles, it balances speed with long-term reliability. The lock operates on four AA alkaline batteries and maintains functionality across a wide temperature range from -20°C to 65°C, ensuring performance in various climates. Its optional WiFi gateway allows integration with existing smart home systems, while Bluetooth connectivity provides direct device management for user administration and settings adjustments.

Features and Construction

The lock's design prioritises accurate fingerprint recognition and durable operation for daily use on various door types. It incorporates specific technical specifications that define its performance parameters and installation requirements.

Material and Build

The lock housing utilises materials suited to indoor environmental conditions, with electronic components protected against humidity fluctuations between 20% and 90%. Its construction focuses on maintaining the fingerprint sensor's accuracy and the mechanical locking mechanism's consistency throughout its 90,000-cycle service life. The internal electronics are calibrated to deliver the stated 0.004% false acceptance rate and 0.0005% false rejection rate, providing reliable security performance without requiring frequent adjustments or recalibration.

Size and Practical Fit

This lock is designed for installation on wooden doors, room doors, office doors, and apartment doors, indicating compatibility with standard residential and commercial door constructions. The power supply utilises four AA alkaline dry batteries, offering a readily available power source that can be replaced without specialised tools. The 1:N comparison method enables the system to match captured fingerprints against the entire registered database efficiently, supporting the quick scanning time while maintaining security standards appropriate for controlled access environments.

Uses and Placement

This fingerprint lock serves environments where key management presents logistical challenges or security concerns, providing individualised access control through biometric verification.

Event or Professional Use

In office settings or commercial apartments, the 200 fingerprint capacity accommodates staff members, tenants, or regular visitors without requiring physical key distribution. The lock's ability to handle over 9,000 unlocking cycles makes it suitable for high-traffic entries where durability is essential. The working temperature range from -20°C to 65°C ensures reliable operation in variously conditioned spaces, from server rooms to standard office environments, while the humidity tolerance supports installation in areas like basement access points or ground-floor entries.

Everyday Home Use

For residential applications, the under 1.5-second scanning time provides convenient access for family members carrying groceries or packages. The Bluetooth connectivity allows homeowners to manage user permissions remotely, adding or removing access as household composition changes. The optional WiFi gateway extends this functionality, enabling integration with voice assistants or home automation routines for hands-free operation. The lock's application specifically to wooden doors and room doors indicates straightforward installation on typical interior and exterior residential doors without extensive modification.

Benefits and Buying Value

The lock offers practical advantages through its technical specifications and design approach, providing measurable performance within defined operational parameters.

Reuse and Low Maintenance

With a 90,000-cycle service life, the lock mechanism is rated for years of daily use across multiple family members or office staff. The use of standard AA alkaline batteries means power can be restored quickly using widely available cells, minimising downtime compared to specialised battery packs. The fingerprint sensor's 0.0005% false rejection rate reduces frustration from legitimate users being denied access, while the 0.004% false acceptance rate maintains security appropriate for residential and standard commercial applications where high-security biometric systems might be excessive.

Why Choose This Product

This lock provides a balanced combination of user capacity, recognition speed, and environmental tolerance for typical indoor installations. The 200 fingerprint storage addresses the needs of multi-user environments without requiring expensive expansion modules, while the Bluetooth and optional WiFi connectivity offer upgrade paths for smart home integration. Its specified performance metrics—scanning time, false acceptance/rejection rates, temperature range—provide clear expectations rather than vague promises, allowing informed decisions based on actual requirements for door security and access management.
