About This

• PALM VEIN BEATS FINGERPRINT — Unlock in 0.2 Seconds, Even Hands Full. Unlike fingerprint locks that fail with wet or worn fingers, the D2 Pro scans internal vein patterns through your palm — contactless, spoof-resistant, and 99.999% accurate. Works while carrying groceries, holding a child, or in bright sunlight (0–100,000 lux). AI self-learning improves recognition over time for every user.
• YOUR BIOMETRIC DATA STAYS LOCAL — No Subscription, No Cloud, No Monthly Fees. All palm vein data is stored directly on the device — never uploaded to the cloud. No subscription fees, no data breach risks. A rare privacy-first feature that keeps your most sensitive biometric information fully in your control.
• BUILT-IN DOORBELL — Know Who's at the Door Without a Separate Device. The integrated doorbell sends instant app alerts the moment visitors ring — no extra wiring, no additional hardware needed. Perfect for Airbnb hosts, families with kids, or anyone who wants complete front door visibility from their phone.
• 6 FLEXIBLE UNLOCKING METHODS — Entry for Everyone in the Household. Unlock with palm vein, touchscreen passcode, TCL Home App, Alexa or Google Assistant voice command, NFC card, or physical key. Supports temporary passcodes for guests and service providers — ideal for rentals, caregivers, and family members of all ages.
• 10,000mAh RECHARGEABLE BATTERY — Up to 8 Months Per Charge. The massive built-in rechargeable battery powers up to 8 months of typical use. Smart energy-saving mode reduces idle consumption, and the app sends low-battery alerts at 20%. USB-C emergency port provides backup power if needed — no lockouts ever.
• ANSI-CERTIFIED & IP55 WEATHERPROOF — Built for Real-World Front Doors. Engineered to ANSI durability standards with 150,000+ cycle testing, premium aluminum alloy construction, and IP55 rain and dust resistance. Handles extreme temperatures, humidity, and heavy daily use — reliable performance year-round for front doors, apartments, and rentals.
• 30-MINUTE DIY INSTALL — Fits Most Standard US Doors Right Out of the Box. No locksmith needed. Installs in under 30 minutes with just a screwdriver. Fits door thickness 1-3/8" or 2-1/8", adjustable backsets 2-3/8" or 2-3/4", supports left- and right-handed doors. Auto-lock timer fully customizable for worry-free security.
