Double-Sided Fingerprint Smart Lock for Enhanced Security
One of the most innovative features of this smart lock is its double-sided authentication system. Unlike traditional smart locks that only support exterior unlocking, this model allows fingerprint verification on both sides of the door. This significantly reduces the risk of forced entry or accidental unlocking from inside.
This feature is particularly useful for glass doors or aluminum frame doors, where reaching inside to unlock can pose a security risk. With dual-side verification, users maintain full control over access, ensuring a higher level of protection for homes, offices, and rental properties.
IP67 Waterproof and Dustproof Smart Lock for Outdoor Use
Durability is a key factor when selecting a smart lock, especially for outdoor installations. This product is equipped with IP67 waterproof and dustproof protection, meaning it can withstand heavy rain, dust, and even temporary water immersion.
Compared to standard IP65 locks, IP67 offers superior protection, making it ideal for environments exposed to extreme weather conditions. Whether installed on a front gate, garden entrance, or coastal property, this smart lock guarantees stable performance without compromising functionality.

170+ Hours Salt Spray Test – Superior Corrosion Resistance
A standout advantage of this smart lock is its exceptional corrosion resistance. It has successfully passed over 170 hours of salt spray testing, far exceeding the typical industry benchmark of 100 hours.
This makes it especially suitable for coastal regions, tropical climates, and high-humidity environments where metal components are prone to rust and degradation. The extended durability ensures a longer product lifespan, reducing maintenance costs and increasing customer satisfaction.
Multiple Unlocking Methods for Flexible Access Control
This smart lock supports a wide range of unlocking methods, offering convenience and versatility:
- Fingerprint Unlock
- Password Unlock
- RFID Card Unlock
- Mechanical Key Backup
- Mobile App Control (Tuya / TTLock)
Users can choose the most suitable method based on their needs. For example, property managers can issue temporary passwords via the app, while homeowners can rely on fingerprint access for quick entry. This flexibility makes it perfect for Airbnb hosts, rental businesses, and smart home users.

Ideal Smart Lock for Aluminum and Glass Doors
Designed with versatility in mind, this smart lock is highly compatible with narrow frame aluminum doors and glass doors. Its sleek and modern design complements contemporary architecture, while its robust internal structure ensures reliable operation.
The combination of aesthetic appeal and high performance makes it a popular choice in markets such as North America, Europe, and Southeast Asia.
