Product Features
Dual-Sided Fingerprint Security
The Tenon K15 is equipped with fingerprint sensors on both the exterior and interior sides. The inner fingerprint sensor helps prevent break-in attempts through security grille door gaps, providing an additional layer of protection for homes with dual-door entrances.
A single fingerprint verification can unlock both the security grille door and the main door, improving convenience for homeowners, families, and property managers.
3D Face Recognition
The advanced 3D face recognition system enables fast, contactless access while helping reduce the risk of unauthorized entry from photographs or flat images. It is a practical solution for users who want keyless entry without touching the lock.
Dual-Camera Blind-Spot-Free Monitoring
The K15 integrates dual cameras to provide front and downward views of the entrance. Its 150° ultra-wide-angle visual peephole, combined with 1.0 MP HD night vision, helps users clearly identify visitors and monitor activity around the door, even in low-light conditions.
This dual-camera design is especially suitable for security grille doors, apartment corridors, outdoor courtyards, and entrances where traditional door viewers may leave blind spots.

3D Face Recognition – Convenient hands-free entry

Biometric Fingerprint – Fast and reliable keyless access
Anti-Peep PIN Code – Enter passwords securely in public areas
Smart IC/RFID Card – Convenient access for family members and staff
Mechanical Backup Key – Reliable emergency access

Remote WiFi Control – Manage access remotely with a compatible WiFi connection
Smart Capacity for Family and Property Management
The K15 supports up to 1,000 PIN codes, 1,000 smart cards, and 100 biometric fingerprints, making it suitable for large households, rental properties, offices, serviced apartments, and residential projects. Administrators can assign and manage different access credentials according to user requirements.
Through the mobile app, users can conveniently manage access permissions, review lock activity, and provide entry authorization without being physically present at the property.
Durable Construction for Tropical Climates
Built with a high-density aluminum alloy body and a heavy-duty SUS304 stainless steel latch bolt, the Tenon K15 offers durability and corrosion resistance for demanding environments. It is designed to operate across a wide temperature range from -25°C to 65°C and withstand humidity levels from 5% to 95% RH, non-condensing.
These characteristics make the K15 particularly suitable for tropical regions, including Singapore's outdoor courtyards, HDB corridors, landed homes, and other high-humidity residential environments.
Long-Lasting Battery and Emergency Power
The smart lock is powered by a high-capacity 7.5V 5000mAh lithium battery. Its low-power design supports extended battery life, with static current of no more than 200uA and dynamic current of no more than 400mA.
For added convenience, the front-facing USB Type-C emergency power interface allows users to connect a power bank when the battery is depleted, helping ensure reliable access during unexpected situations.
A Smarter and Safer Entrance Solution
The Tenon K15 3D Face & Dual-Camera Smart Lock combines advanced biometrics, dual-door linkage, real-time visual monitoring, and smart app connectivity in one reliable security solution. Its dual-sided fingerprint design is especially valuable for homes with security grille doors and main doors, helping protect against forced entry while providing a faster and more convenient unlocking experience.
For homeowners, developers, security grille door manufacturers, and smart home solution providers, the Tenon K15 offers a durable, flexible, and future-ready approach to residential access control.
