Facial Recognition Smart Locks Enter Residential Market

Facial recognition is emerging as a high-tech alternative for residential access, aiming to provide a frictionless entry experience without requiring a mobile device. According to reporting from The Verge, these locks utilize infrared sensors to create 3D maps of a user's face using methods such as time-of-flight sensing, stereo infrared cameras, or structured light. This 3D mapping is intended to prevent security breaches, as the depth capture typically prevents the system from being fooled by a photograph.

In testing by The Verge senior smart home reviewer Jennifer Pattison Tuohy, four primary models were evaluated: the $300 Eufy FamiLock E40, the $350 Lockly Visage Zeno, the $230 Switchbot Lock Vision Pro, and the $199 Lockin Veno Solar Face. The Eufy FamiLock E40 was identified as the top performer, unlocking in under a second and maintaining consistency while the user wore sunglasses. However, the E40 was noted for having a bulky design and the fastest battery drain among the group.

While facial recognition offers a "sci-fi" experience for those who leave their phones behind, it faces competition from ultrawideband (UWB) radio technology. The Verge notes that UWB provides a fast and reliable hands-free experience, though such locks remain expensive and limited in availability.
