Product Description Next-Generation Facial & Palm Vein Recognition: Unlock your door effortlessly using advanced 3D facial or palm vein recognition. No keys, no touch, just pure convenience. Whether you’re holding your child, carrying heavy bags, or caught in the rain, simply reach out and the door unlocks instantly. Even in complete darkness, the lock accurately identifies you and opens within seconds. (False recognition rate below 0.0001%. Facial recognition range: 0.6–0.9 m; Palm vein range: 8–25 cm.) Data Security Protection: Equipped with bank-grade 3D structured light facial recognition and AES-128 encryption, your privacy is fully protected. All facial and palm vein data are stored locally, never uploaded to the cloud—ensuring maximum security and peace of mind. Triple Power Protection for Extended Battery Life: Lock Ultra features an upgraded built-in rechargeable main battery plus an additional emergency battery for continuous operation. When the main battery is charging, the emergency battery automatically takes over to ensure the lock keeps working. Even when both batteries are low, micro-power unlocking gathers minimal current to provide just enough power for emergency access. Better Fit for Existing Door Locks: Designed with a sleek all-metal body that’s 50% slimmer, this smart lock offers a refined magnetic quick-release system and seamless base ring for true zero-gap installation. No drilling or damage required—install it easily on your existing door lock in just minutes. Comes with 3 stylish wood-grain finish stickers to match any home décor. For uncommon door types, an optional Adapter Kit (sold separately) ensures compatibility with 99% of lock designs. Multiple Ways to Unlock: In addition to the all-new facial and palm vein recognition, the SwitchBot Lock Ultra Vision Pro Combo also supports unlocking via fingerprint, passcode, voice command, Apple Watch, and remote control through the SwitchBot App. The set includes a Matter-supported Hub Mini, ensuring full compatibility with HomeKit, Alexa, Google Assistant, and other third-party smart home platforms.
