Hardware Specifications
At the core of the TCL D2 Pro is robust construction from aluminium alloy, measuring 240 × 145 × 90 mm and weighing just 1.42 kg for easy installation on standard doors. The palm vein digital door lock employs next-generation biometric scanning that's hygienic and spoof-proof, storing up to 50 palms locally for privacy-no cloud risks here. It supports 50 passwords via the anti-peep touchscreen keypad, preventing shoulder-surfing. A built-in doorbell adds convenience, ringing inside and sending app alerts. Power comes from a 10000mAh battery with USB-C recharging and an emergency battery port for low-power situations. Tamper alerts and auto-lock features activate on door closure, enhancing daily security. Rated IP55, it withstands rain, dust, and extreme temperatures, thriving in all seasons without faltering.
The device's locking system adjusts for door thicknesses from 2-3/8 to 2-3/4 inches, requiring no major modifications. Everything needed arrives in the box: interior and exterior parts, mounting plate, screws, drilling template, two NFC fobs, physical keys, and a clear manual. Installation takes about 10 minutes with basic tools, making it DIY-friendly for most users.

Built-in WiFi eliminates the need for extra hubs, providing constant connectivity for remote monitoring and control through the TCL Home Security app. Grant temporary access, set schedules, or view entry logs from your smartphone anywhere. Real-time notifications alert you to every activity, ensuring you're always in the loop. Voice control shines with compatibility for Alexa and Google Assistant-say "unlock the door" or check status hands-free. This extends to SmartThings ecosystems for broader home automation.
