Huawei has officially unveiled the Smart Door Lock 2 in China, now featuring cutting-edge AI-powered palm vein recognition—a contactless, highly secure biometric method designed to raise the bar in smart home security.
Next-Level Biometric Unlocking
The standout feature of the Smart Door Lock 2 is its palm vein recognition system. It employs near-infrared imaging to scan the unique pattern of veins beneath the palm, offering significantly improved security compared to fingerprints or facial recognition—even if your skin is wet or slightly injured. The infrared “air swipe” gesture enables seamless, touch-free unlocking.
Enhanced Hardware and Smart Features
- Upgraded NPU chip offers 1.5× faster processing and up to 25T computing power for quicker recognition.
- A stunning 2K ultra-clear “Cat Eye” camera with a 161° wide field of view offers 28% more coverage and improved exposure handling.
- Supports multiple unlocking options: palm vein, fingerprint, numeric PIN, app control, guest codes, and mechanical keys.
- Built-in emergency red button, 10,000 mAh battery (3–5 months runtime), AA battery backup, and USB-C emergency power input.
- Robust design: die-cast body, noise-reducing mechanism, EAL5+ encryption, C-level anti-theft cylinder, and HarmonyOS 5 integration for full smart home control.
Pro & Ultra Models—The Premium Biometric Upgrade
Huawei also introduced the Smart Door Lock 2 Pro and Ultra, expanding the biometric features of the standard model:
- Introduce 3D facial recognition via a Time-of-Flight (ToF) camera analyzing over 307,200 facial points, complete with liveness detection to thwart spoofing through masks or videos.
- Include the same advanced palm vein recognition for versatile access.
- Feature the same 2K HD peephole with smart AI detection, two-way intercom, cloud storage, and HarmonyOS ecosystem connectivity.
- Boast IPX5 water resistance, die-cast durability, and rigorous stress testing for real-world reliability.
- Battery setup mirrors the standard unit with long-lasting power and backup options.
