SwitchBot has raised the bar in home security with the launch of two new smart locks, the Lock Vision and Lock Vision Pro. Both devices leverage the Matter protocol for connectivity and integrate a next-generation 3D facial recognition system. This technology, based on structured infrared light, promises to unlock the door in under one second with millimeter-level precision. The most interesting innovation is the impossibility of fooling the sensor with photos or videos, even if the user wears glasses, hats, or heavy makeup. This represents a significant step forward from traditional fingerprint readers or numeric codes, especially for those seeking a truly contactless access experience.
Smartphone-grade facial recognition technology
The core of the system is a 3D structured light module that projects over 20,000 infrared dots onto the user's face, creating a detailed three-dimensional facial map. SwitchBot claims that the accuracy level is comparable to that of top-tier flagship smartphones, such as those using Apple's Face ID. Biometric data is processed and stored entirely on the device, never leaving the lock: a design choice that addresses the growing concerns about privacy in the smart home ecosystem. This edge computing approach eliminates the risk of exposing sensitive data in the cloud or during transmission.
In addition to facial recognition, the locks offer multiple unlocking methods. The Pro version adds palm vein recognition and fingerprint scanning, while both models support NFC, numeric passwords, iPhone app controls, Apple Watch, Siri voice commands, geofencing, and physical backup keys. The integrated mmWave radar sensor detects a person approaching and can automatically activate the camera or prepare the system for unlocking, optimizing energy consumption.
Integration with the Apple ecosystem and beyond
Thanks to Matter-over-WiFi connectivity, the locks are natively compatible with HomeKit and integrate seamlessly into an Apple Home setup. No central hub is required, simplifying installation and daily management. Users can create automations such as turning on lights upon arrival or deactivating the security alarm when facial recognition is successfully completed. The battery has a stated life of 12 months, with emergency backup power options. This makes them ideal candidates for replacing a standard deadbolt with a modern solution without rewiring existing infrastructure.
The arrival of these locks comes at a time when AI applied to security is making great strides. The same type of facial recognition technology is also being used in the social media space, as demonstrated by the recent expansion of deepfake detection tools on YouTube, a sign that AI is becoming a bulwark against visual fraud.

Pricing and availability
The SwitchBot Lock Vision is available at 170 dollars, while the Lock Vision Pro costs 230 dollars. At launch, a 40-dollar discount is active both on Amazon and on the company's official website. Given the advanced features and cross-platform compatibility, these prices represent a competitive offer in the high-end smart lock market. The future of home security is becoming increasingly invisible, automated, and personalized, with devices that recognize who we are without the need for keys or codes.
