Bottom Line
Choose it if you want one app for your lock, camera, and doorbell plus fast fingerprint access. Skip it if battery longevity or package-view camera coverage matters more than this clean all-in-one design.
Best for
Homeowners who want a clean 3-in-1 setup with strong fingerprint unlocking, remote control, local video storage, and optional Alexa or Google integration. It fits best on standard doors without storm or screen-door complications.
Not for
Anyone who needs long battery intervals, a package-friendly vertical view, true door-position sensing, or reliable performance with deep jambs and screen doors. It is also a weaker fit if HomeKit support is essential.
Verdict
The eufy Video Smart Lock E330 is one of the more convincing all-in-one door devices because the lock side is consistently strong: installation is usually easy, fingerprint entry is fast, app control is polished, and alerts arrive quickly. The tradeoff is that the camera side is more situational than a dedicated video doorbell. Several reviewers liked the sharp 2K picture and local storage, but many also reported a narrow vertical view, awkward visitor button discovery at night, and battery life that often falls well short of the marketing claim once motion and video features are active. If your door layout suits it and you accept more frequent charging, it is a smart, streamlined upgrade.
Pros
-
The lock mechanism itself is consistently dependable in reviews, with few complaints about failed locking or unlocking once properly installed and calibrated.
-
Notifications are a strong point, with repeated praise for fast alerts from motion events, doorbell presses, and lock actions.
-
Locking and unlocking are generally quick, especially by fingerprint, with several reviewers describing the response as near-instant or sub-second.
-
Fingerprint entry is one of the product's clearest wins, repeatedly described as fast, accurate, and the preferred way to unlock.
-
Installation is usually quick and straightforward for standard doors, often landing in the 10-20 minute range, though edge cases can require minor door work.
-
The Eufy app is broadly praised for setup, live view, quick lock controls, access management, and clear event history, with few complaints beyond battery-related settings tradeoffs.
-
Auto-lock is widely described as reliable and flexible, with adjustable timers and scheduling, though it is timer-based rather than true door-position sensing.
-
Remote locking, unlocking, live view, and answering the door from the app all work well and are central to the product's appeal.
-
Guest access is flexible, with permanent, temporary, scheduled, and one-time code options that reviewers found genuinely useful.
-
The adjustable deadbolt and removable fit pieces help it adapt to common backset and bore variations on standard doors.
-
Limited direct commentary suggests the motor is reasonably quick and quiet, but this is not as heavily discussed as fingerprint speed or battery drain.
-
Evidence is limited but positive, including BHMA-related claims and durability figures that suggest a sturdier-than-average smart lock build.
-
User management is robust, supporting admins, shared users, remote passcode assignment, and sizeable limits for codes and fingerprints.
-
Weather resistance is generally viewed as solid for outdoor use, with repeated IP65 mentions and positive rain-use feedback, even if one comparison suggested a lower resistance tier than the S330.
-
Wi-Fi performance is typically stable once connected, with fast remote access and alerts, but setup expects a 2.4 GHz network.
-
Build quality is generally rated highly, with reviewers calling the exterior solid, premium-looking, and well made for a lock-camera combo.
-
Event history is a consistent strength, with multiple reviewers highlighting detailed lock and camera logs that can identify who unlocked the door by fingerprint or code.
-
The touch-sensitive keypad is responsive and modern, though nighttime discoverability is not as polished as on some dedicated doorbells.
-
The hidden physical key and external USB-C emergency power option give the E330 credible backup access if the battery runs down.
-
Integration is good but not universal: Alexa and Google are commonly supported, HomeBase 3 adds more capability, and HomeKit support is notably absent.
-
Voice control through Alexa or Google is commonly supported and useful for basic lock commands, though it is more of a convenience layer than a standout feature.
-
A hub is optional rather than required: the lock works on its own, while HomeBase 3 mainly adds AI features, storage flexibility, and ecosystem extras.
-
The keypad works well and supports scramble PIN entry, but several reviewers note that the button area can be hard for visitors to find in the dark.
-
Reviewers generally liked the sharp 2K image, usable night vision, fast live view, and subscription-free local storage, but the camera side remains more compromised than a dedicated video doorbell because field of view, package visibility, and button discoverability can vary a lot by door layout.
-
Wrong-try protection appears well implemented, letting owners lock out further attempts after repeated bad fingerprints or PIN entries.
-
Bluetooth helps with setup and is mentioned by some reviewers as an available unlock path, though Wi-Fi and fingerprint are the primary day-to-day methods.
-
Support and warranty coverage look adequate rather than exceptional, with a one-year warranty mentioned and at least one battery-drain support interaction that did not fully solve the issue.
-
Battery life is the biggest unresolved weakness: light use can be respectable, but several reviewers saw much shorter runtimes than the 8-12 month marketing claim once motion, video, and notifications were active.
-
Value is mixed: the combined lock-camera-doorbell design and no-subscription local storage are appealing, but the price stings more when battery life or fit issues reduce the benefit.
-
Some installations reuse the existing strike plate or fit the current bore cleanly, but others require minor modification or a new strike fit.
Cons
-
It fits standard deadbolt doors well, but compatibility gets worse with deep jambs, screen doors, unusual spacing, or layouts that block the camera's view.
-
The physical key backup is useful, but the cylinder cannot be rekeyed, which several reviewers see as a practical downside.
-
Reviews indicate the E330 lacks true door-open and door-closed sensing, so auto-lock relies on timers instead of confirming the door position.
-
Lineup comparisons indicate the E330 does not offer the location-based auto features found on higher-tier Eufy models.
FAQ
Does the E330 need a HomeBase to work?
No. Multiple reviews say it works standalone over Wi-Fi with built-in local storage, while HomeBase 3 is optional for added AI features, storage flexibility, and chime behavior.
How long does the battery last in real use?
Real-world results vary a lot. Light-use testing looked much better, but several reviewers saw anything from roughly a month or two to around a few months once motion detection, video recording, and auto-lock features were active.
Does it support Apple HomeKit?
The reviews consistently mention Alexa and Google support, but one reviewer explicitly notes that HomeKit is not supported on this model.
Can it replace both a smart lock and a video doorbell?
Yes, that is the main appeal. It combines a deadbolt, keypad and fingerprint lock, camera, and doorbell in one device, but the camera view is narrower and more door-position-dependent than many dedicated video doorbells.
