eufy Video Smart Lock E330 Review
Bottom Line
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
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
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.
Verdict
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.

-
The app was consistently praised as simple, polished, and useful for setup, live view, lock control, access management, and monitoring.
-
Notifications were a clear strength, with reviewers describing alerts as nearly instant, responsive, fast, or consistent.
Cons
-

-
Door compatibility was a major caveat because screen doors, storm doors, deep jambs, and awkward door angles could compromise the camera or overall fit.

Door-sense was weakly supported because a reviewer specifically wanted a sensor to know whether the door was open or closed.
