TCL's Latest Innovation: The D2 Pro Palm Vein Smart Lock

In a game-changing move for smart home security, TCL has unveiled its revolutionary D2 Series Smart Locks, featuring the star of the show—the TCL D2 Pro Palm Vein Smart Lock. Following the outstanding success of its predecessor, the D1 Pro, which took the market by storm in 2025 with multiple prestigious awards and top sales on Amazon, TCL is setting new standards with this cutting-edge device.

Superior Features That Stand Out

### Unmatched Accuracy and Speed

The D2 Pro boasts an astonishing 99.9999% accuracy in palm vein recognition, tested rigorously in lab conditions. Forget about fingerprints or facial recognition; this innovative technology is impervious to moisture, dirt, or age, offering reliability like never before. And with a lightning-fast 0.3-second unlock, you can gain access faster than a blink—just wave your hand and voilà!

Privacy Meets Convenience

### Total Local Data Control

Security is a top priority for TCL. The D2 Pro stores all biometric templates and access logs exclusively on the device, ensuring no data is transmitted to the cloud. This means no exposure to potential hacker threats or data leaks! Plus, it features flexible guest management with temporary PINs and shareable QR codes, allowing tiered access for family, friends, or service providers.

Battery Life That Lasts

### Power that Keeps Going

With a robust 10,000 mAh built-in battery, the D2 Pro guarantees up to 240 days of operation on a single charge. Worried about a low battery? An LED and app notifications will keep you informed, and there's even a USB-C port for emergency charging!

Seamless Integration into Smart Homes

### Control at Your Fingertips

Effortlessly integrate the D2 Pro into your smart home ecosystem. Control and monitor your lock via the TCL Home Security App, complete with real-time notifications and detailed activity history. It also works hand-in-hand with Amazon Alexa and Google Assistant for voice-activated unlocking and automation—because convenience is key!
