Score: 85/100Rankings

The eufy Security Video Smart Lock S330 is a comprehensive 3-in-1 device combining fingerprint deadbolt, 2K HD camera, and video doorbell with chime. It offers keyless entry via app, voice, keypad, or keys, powered by a single 10,000 mAh battery that lasts up to 365 days without requiring subscription fees. It is ideal for families or frequent travelers needing all-in-one front-door monitoring without subscriptions.

The August Home Smart Lock Pro is a versatile retrofit lock that installs over existing deadbolts, offering broad smart home integration via Z-Wave and a separate WiFi bridge. Its main drawback is the reliance on an additional hub for remote features and the lack of modern entry methods like fingerprint scanning. It is ideal for users with Z-Wave hubs who want to retain their physical keys.
