Choose the eufy Video Smart Lock E330 if you want one polished lock, camera, and doorbell with excellent fingerprint access. Skip it if short battery life, screen/storm doors, or a narrow camera view would frustrate you.
Best for shoppers with a compatible, uncovered door who want one device for fingerprint entry, app control, doorbell alerts, and 2K monitoring. It also suits users already comfortable with Eufy, Alexa, Google, or HomeBase-style setups.
Not for screen-door or storm-door setups, people who need Apple HomeKit, easy rekeying, or a wide package-focused doorbell view. It is also a poor fit for anyone unwilling to manage rechargeable battery tradeoffs.
The eufy Video Smart Lock E330 earns strong praise as a polished all-in-one smart lock, doorbell, and security camera. Reviewers repeatedly liked the fast fingerprint reader, simple setup, responsive app, quick notifications, and sharp 2K video. The tradeoff is that combining video surveillance with a rechargeable smart lock makes placement and battery management more important than with a simpler deadbolt. Some reviewers saw excellent battery performance, while others found the battery drained fast enough to undermine the product’s best features. Camera view is also setup-dependent, especially with screen doors, storm doors, deep jambs, or awkward door angles.

Yes. Reviewers repeatedly described installation as quick, straightforward, foolproof, or among the easiest smart-lock setups they had tried.
It was one of the strongest points in the reviews. Reviewers called it fast, accurate, responsive, convenient, and often preferred it over keypad entry.
Battery life was mixed. Some reviewers reported months of use or liked the removable rechargeable pack, while others saw enough drain that they disabled video features or expected frequent charging.
For the right door, yes. Reviewers liked the 2K video, night vision, quick alerts, and two-way features, but several warned that narrow viewing angles, screen doors, storm doors, or deep jambs can limit the camera.
Reviewers cited Alexa, Google, Apple Watch, Eufy camera integration, and HomeBase options. The main smart-home drawback was the lack of Apple HomeKit support.
Yes. Reviewers liked passcodes, scheduled or one-time access, fingerprints, and user management, including one case where giving guests a passcode was called a godsend.
