The eufy C220 is a premium hub-free smart lock featuring Matter support, IP53 waterproofing, and USB-C emergency power.

It is best suited for users in extreme weather environments or those prioritizing maximum security certifications.
The eufy Security Video Smart Lock S330 is a 3-in-1 device combining a fingerprint deadbolt, 2K HD camera, and video doorbell with chime.
