Smart Bluetooth fingerprint lock for doors with WiFi gateway, 200 fingerprint capacity, and 1:n comparison method

This smart Bluetooth fingerprint lock provides keyless electronic access for residential and commercial doors including wooden doors, room doors, office doors, and apartment doors. The device supports multiple authentication methods including fingerprint recognition, Bluetooth connectivity, and optional WiFi gateway functionality for remote access management. With capacity for storing 200 individual fingerprints and a scanning time under 1.5 seconds, it offers convenient entry for households or workplaces with multiple regular users. The lock's operating parameters accommodate various environmental conditions, functioning reliably in temperatures ranging from -20°C to 65°C and humidity levels between 20% and 90% for consistent performance throughout seasonal changes.

Features and Construction

The fingerprint lock combines electronic authentication with mechanical operation, powered by four standard No.5 alkaline dry batteries that eliminate the need for hardwired electrical connections. This battery-powered design simplifies installation on various door types without requiring professional electrical work or proximity to power outlets. The lock's mechanical components are rated for 90,000 unlocking cycles, providing long-term reliability for daily use in residential or commercial settings where door access occurs multiple times daily.

Material and Build

Available in black or silver finishes, the lock housing accommodates different aesthetic preferences while protecting internal electronic components. The construction integrates fingerprint scanning technology with Bluetooth communication capabilities, supporting both direct user interaction and remote access management when paired with compatible devices. The physical build withstands regular operation within specified environmental parameters, maintaining functionality across temperature extremes from sub-zero winter conditions to hot summer environments.

Size and Practical Fit

Designed specifically for installation on wooden doors, room doors, office doors, and apartment doors, the lock adapts to standard residential and commercial door configurations. The product specifications focus on operational performance rather than physical dimensions, with performance metrics including scanning time under 1.5 seconds and admission rates below 0.004% taking priority over exact measurement data. This practical orientation ensures reliable authentication speed for daily use scenarios where quick access is preferable.

Uses and Placement

The fingerprint lock serves both residential households and commercial environments where controlled access is required without traditional key management. In apartments or family homes, the 200 fingerprint capacity accommodates multiple household members along with occasional visitors or service providers. For office settings, the same capacity supports employee access while maintaining individual accountability through distinct fingerprint profiles. The WiFi gateway option expands functionality for property managers or business owners requiring remote access control or usage monitoring capabilities.

Event or Professional Use

For professional environments, the 1:n comparison method allows the system to identify users from the stored database without requiring them to specify which fingerprint template to use, streamlining the authentication process during busy periods. The operating temperature range from -20°C to 65°C ensures reliability in various climates, from heated interior spaces to exterior doors exposed to seasonal weather changes. With over 9,000 unlocking operations supported between battery changes and a mechanical lifespan of 90,000 cycles, the lock maintains consistent performance through extended periods of regular use.

Everyday Home Use

In residential applications, the fingerprint lock eliminates concerns about lost keys or unauthorized key duplication while providing family members with individual access profiles. The admission rate below 0.004% and rejection rate under 0.0005% minimise authentication errors that could frustrate users or prevent legitimate access. Operating humidity parameters between 20% and 90% accommodate various indoor climate conditions, from dry winter heating environments to humid summer periods without compromising fingerprint recognition accuracy.

Benefits and Buying Value

The fingerprint lock reduces physical key management while maintaining individual access control through biometric authentication. By supporting 200 separate fingerprint profiles, it accommodates extended families, rental properties with multiple tenants, or small businesses with employee turnover. The combination of fingerprint, Bluetooth, and optional WiFi gateway access methods provides flexibility for different user preferences and technological comfort levels, from direct physical interaction to smartphone-enabled remote management.

Reuse and Low Maintenance

Powered by standard No.5 alkaline batteries with a mechanical lifespan of 90,000 cycles, the lock requires minimal ongoing maintenance beyond periodic battery replacement. The environmental operating range reduces weather-related concerns for exterior applications, while the fingerprint recognition system maintains accuracy across temperature and humidity variations. With over 9,000 unlocking operations between battery changes, users experience extended periods of reliable functionality without frequent maintenance interruptions.

Why Choose This Product

This fingerprint lock offers specific technical advantages including scanning speed under 1.5 seconds for quick access, high fingerprint capacity for multiple users, and robust environmental tolerances for various installation locations. The 1:n comparison method simplifies authentication by automatically matching fingerprints against all stored profiles rather than requiring user identification first. Combined with the optional WiFi gateway for remote management capabilities, these features provide a comprehensive access control solution adaptable to residential or commercial security requirements without complex installation procedures.
