Product angle
The Verge review details the current state of facial recognition smart locks, emphasizing the balance of convenience and security this tech can provide. Facial recognition uses 3D infrared mapping to prevent spoofing by photos and enables quick hands-free entry. According to the source, the Eufy FamiLock E40 outperforms competitors in unlock speed, accuracy—even with sunglasses—and multi-modal access, integrating biometric and traditional methods into one device.
The review also notes the E40's design blend with traditional locks, its built-in 2K video doorbell functionality without recurring subscription fees, and support for the Matter standard, which facilitates interoperation within diverse smart home ecosystems. These features make it a comprehensive solution not only for unlocking but also for front door monitoring and smart home connectivity.
Best for / avoid if
This smart lock is best suited for early adopters and tech-savvy homeowners who value fast, seamless access without relying solely on smartphones or physical keys. It particularly benefits households where some members may leave phones behind, as facial recognition does not require carrying a device. It also appeals to users who want a multi-modal security system combining biometrics, keypad, and a physical key option.
Potential buyers should avoid the Eufy FamiLock E40 if they prefer low-maintenance locks, since the device demands frequent charging and has a high drain on its main battery. Its large physical size may be unsuitable for some door styles or aesthetic preferences, and its premium price point may deter budget-conscious customers. Those seeking a simpler or less power-dependent lock might consider alternatives.
Pricing and alternatives to check
The Eufy FamiLock E40 is priced around $300, placing it at the higher end of the facial recognition lock market. Other available options mentioned include the Lockly Visage Zeno priced at about $350, Switchbot Lock Vision Pro at $230, and Lockin’s Veno Solar Face at $199, each offering varying features and biometric capabilities. These alternatives might appeal to buyers with different budget constraints or specific ecosystem preferences such as Apple compatibility.
The Verge review also highlights that hands-free unlocking via ultrawideband (UWB) technology may provide faster and more reliable unlocking but currently remains scarce and costly. Buyers interested in integrating their smart locks with wider smart home setups may want to consider the supported smart home standards and video doorbell capabilities when comparing alternatives.
