This 3D face recognition smart lock integrates a high-definition camera and a video doorbell into a single unit, offering a comprehensive access control solution for front doors. The lock features a robust IP67-rated waterproof enclosure, ensuring reliable operation in outdoor environments exposed to rain, dust, and temperature fluctuations. Its 4.5-inch HD screen provides clear visual feedback during setup and daily use, while the two-way talk function allows remote communication with visitors through the Tuya smart home app. The primary authentication method is 3D facial recognition, which uses depth-sensing technology to accurately identify authorized users even in low-light conditions. Additional keyless entry modes include a physical key override, touchscreen passcode, RFID card, smartphone app unlocking, and temporary access codes for guests or service personnel. All communication between the lock and the Tuya app is encrypted, supporting remote monitoring and real-time event logs.

Constructed from zinc alloy and tempered glass, the lock’s exterior shell resists impacts and corrosion. The internal motor and circuit board are sealed to prevent moisture ingress, contributing to long-term durability. The seven-in-one design eliminates the need for separate devices, streamlining the entryway while maintaining high security standards. Power is supplied by a rechargeable lithium battery, which provides several months of typical use before needing a recharge. Low-battery alerts are sent via the app, ensuring users are never locked out unexpectedly. The 2.4 GHz Wi-Fi module maintains a stable connection to the home network, enabling push notifications when the doorbell is pressed or unauthorized attempts are detected. The built-in infrared night vision ensures the camera captures clear images around the clock. With an intuitive interface and easy installation process, this smart lock suits homeowners who prioritize both convenience and security. Its competitive pricing positions it as a value-driven alternative to premium smart lock systems.
