Choose the eufy Video Smart Lock S330 if you want one wireless lock, camera, doorbell, and fingerprint system. Skip it if you need HomeKit/Matter, a subtle doorbell button, or tolerance for imperfect door alignment.
Best for households that want one wireless device to handle locking, video doorbell duties, remote access, guest access, and fingerprint entry. It especially fits users who value local storage and do not want separate lock and doorbell hardware.
Not for users who need Apple HomeKit, Matter, IFTTT, subtle hardware, or long-range camera coverage. It is also a poor fit for doors with marginal deadbolt alignment unless the installer is willing to fine-tune the strike area.
The eufy Video Smart Lock S330 stands out as an ambitious front-door all-in-one: reviewers repeatedly liked the fingerprint unlock, local-storage-friendly camera setup, remote control, and broad access options. Its best moments are convenience-driven, especially for households, contractors, deliveries, or anyone who wants a lock and video doorbell in one wireless unit. The tradeoff is that the product asks for more patience and space than a simpler smart lock. Some reviewers found installation and calibration easy, while others hit door-fit or jam-message frustrations, and camera/motion performance ranged from excellent to delayed or limited at distance. The strongest evidence points to a feature-rich, generally reliable lock with a few rough edges around setup precision, ecosystem limits, and event detection.

Most reviewers found installation easy or manageable, but several noted that door alignment, strike-plate depth, or physical size can make setup tricky.
Most evidence is very positive, with reviewers calling it fast, accurate, and instant. One reviewer had repeated failed reads, so performance may depend on the user or setup.
Reviewers generally liked the 2K video clarity and door-area visibility. The main caveats were delayed motion recording, weaker long-distance detail, and some missed motion or loitering events.
Battery life was repeatedly praised as long-lasting, with some reviewers reporting months between charges. One reviewer noted that a full recharge can take several hours.
Yes. Reviewers valued being able to check or unlock the door from the app, including while away from home, and several liked using it for guest or contractor access.
Review evidence notes Alexa and Google support, but not Apple HomeKit, IFTTT, or Matter. Reviewers treated this as a limitation for broader smart-home interoperability.
Most reviewers considered the price reasonable because it combines a smart lock, doorbell, 2K camera, fingerprint reader, app access, chime, and local-storage options in one device.
