TCL has recently broadened its range of smart home devices by launching the new D2 Pro palm vein smart door lock. The company has released three models in the D2 series: the D2, the D2 Plus, and the D2 Pro. Building on the previous D1 Pro, the D2 Pro brings several improvements, particularly in battery life and additional features. Notably, the TCL D2 Pro is now equipped with a built-in doorbell.
Advanced Technology Features
As indicated by its name, the TCL D2 Pro employs AI-driven palm vein recognition technology for unlocking doors. This innovative feature examines the blood vessels beneath the skin, offering a remarkable accuracy of 99.99% and unlocking in just 0.3 seconds. The biometric authentication method is said to work effectively even when fingers are wet or dirty. Additionally, there are four other ways to unlock the door: via app, passcodes, a physical key, and voice commands.
Comparison with Other Models
We have previously discussed the D2 Pro smart lock in a different article; you can check that out here. In contrast to the D2 Pro, the standard D2 and D2 Plus models do not feature palm vein recognition. Instead, they provide PIN codes, physical keys, and mobile app options for access. The D2 Plus does include an AI-enhanced fingerprint biometric option, which is not available on the Pro or base D2 models.
Common Features Across the Series
All models in the D2 series share features such as voice control through Amazon Alexa and Google Assistant, remote unlocking, along with app management that provides real-time notifications and activity logs. They are compatible with 2.4 GHz WiFi and include an auto-lock feature for better home security. The D2 Pro is powered by a rechargeable battery, while the D2 Plus utilizes AA batteries, which are said to last up to 9 months with a single set.
Pricing and Availability
Regarding pricing, the TCL D2 Pro retails for $169.99, the D2 Plus starts at $119.99, and the base D2 model is priced at $79.99. The TCL D2 series can now be bought from TCL’s official website as well as Amazon.
