Chinese smart home automation firm SwitchBot is leveraging the same facial-recognition technology used on smartphones to help people enter their own homes.

It is launching its SwitchBot Lock Vision Series in North America to speed smart home entry. The smart deadbolt lock is equipped with 3D structured-light facial recognition technology, delivering faster, safer and more effortless unlocking for modern households.

Inspired by the same core technology used in flagship smartphones, the series projects more than 20,000 infra-red points to create accurate 3D facial maps capable of millimetre-level recognition. The system unlocks doors in under one second while resisting spoofing attempts using photos or videos. The technology works reliably even when users are wearing glasses, hats, wigs or makeup.

Multiple unlock methods include 3D facial recognition, app control, NFC cards, passwords, voice assistants, smartwatch control, auto-unlock via geo-fencing and physical keys. It further expands biometric access with contactless palm vein recognition and semiconductor fingerprint unlocking. Using near-infra-red sensing technology, palm vein recognition enables users to unlock doors without touching the device, even when hands are wet, dirty or difficult to scan with conventional fingerprint readers.

By storing all biometric information locally with AES-128 encrypted communication, the series prioritises privacy and security.

To reduce concerns around battery anxiety and lockouts, it uses the firm’s DualPower and DualBackup systems. A built-in 10,000mAh rechargeable battery can power the lock for up to 12 months on a single charge under typical usage conditions, while an additional CR123A backup battery provides up to 500 emergency unlocks. In emergency situations, users can also temporarily power the device via the USB-C emergency power port; the port provides temporary power and does not charge the lock.

To improve power efficiency, the lock uses mm-wave radar detection, activating biometric recognition only when someone approaches the door. The app also provides real-time battery monitoring and low-battery notifications.

The series supports Matter-over-wifi, allowing users to connect directly with supported smart home ecosystems without requiring an additional Matter-enabled hub. The locks are designed to work with Apple Home and integrate naturally with the broader SwitchBot ecosystem. Users are not able to access, retrieve or manage any biometric information on any third-party platforms, as all the biometric information is stored locally.

When paired with other SwitchBot products, the series enables expanded smart home experiences. Combined with the SwitchBot Smart Video Doorbell, users can monitor activity outside the door, remotely unlock for visitors and automate entry workflows. With Wallet Finder Card integration, users can also use the tracking card as an NFC key for unlocking the door.

A six-tier security protection system covers alarm security, locking, unlocking, communications, storage and power security. Features include tamper alerts, forced unlock protection, emergency SOS fingerprint recognition, remote unlock confirmation and automatic lockout after repeated failed verification attempts.

The series is rated IP65 for water and dust resistance, helping ensure reliable performance in various weather conditions. Designed for broad compatibility with most deadbolt locks, the technology can be installed in approximately 15 minutes using only a screwdriver.
