A Leap in Smart Home Security
Building on the success of the original Smart Door Lock 4 Pro, Xiaomi’s new Dual Camera Edition takes security and convenience to a whole new level. With faster unlocking, multiple biometric authentication options, and seamless smart home integration, this model targets homeowners seeking both safety and modernity in one device.
Key Features of Xiaomi Smart Door Lock 4 Pro Dual Camera Edition
AI Palm Vein Recognition Technology
One of the standout features of this smart lock is AI-powered palm vein recognition. Using near-infrared light, the system scans the unique vein patterns in your hand, providing unmatched security.
