The eufy Security Smart Lock C220 is a hub-free, Wi-Fi-enabled deadbolt with BHMA Grade 3 security and AI fingerprint recognition.

It is best suited for high-traffic households and users in extreme climates.
The Yale Assure Lock is a smart lever door lock with a backlit touchscreen and built-in Wi-Fi capabilities via a smart module. It offers extensive user code capacity and seamless integration with major smart home ecosystems. The lever design and Grade 2 rating make it less suitable for high-security front doors. It is ideal for tech-savvy homeowners and renters seeking keyless convenience.
