U3F

U3F is a smart lock with modular, replaceable hard-anodized aluminum panels. Its asymmetric U-shaped structure integrates radar sensing, 3D facial recognition, a concealed fingerprint sensor, and three cameras. Automatic unlocking, a quick-open handle, and automatic locking enable hands-free entry. A 4.5-inch HD display improves visibility for children and older users. Replaceable panels extend the product lifespan while reducing material consumption and upgrade costs.
