Bottom Line
Choose the eufy Video Smart Lock E330 if you want keyless entry plus a built-in doorbell camera in one unit. Skip it if you need set-and-forget battery life or a wide, package-friendly view.
Best for
Homes that want one tidy device for fast fingerprint entry plus subscription-free doorstep clips, especially on a side or back door with a clear, head-on view and moderate traffic.
Not for
Anyone who needs months of battery life with always-on motion recording, or doors with screen/storm doors or tricky angles where the lock-mounted camera cannot see packages and full-body approach well.
Verdict
The E330 is at its best when you want one device to handle everyday entry and basic doorstep monitoring without paying a video subscription. Across reviewers, the fingerprint reader is consistently quick and forgiving, the app is polished, and alerts arrive fast enough to feel like a real doorbell replacement. The tradeoff is power and placement: enabling motion recording can shorten recharge intervals dramatically for some homes, and the lock-mounted camera can feel narrow or obstructed by door frames or screen doors. If your door layout is compatible and you are comfortable topping up (or keeping a spare battery), it is a genuinely convenient all-in-one.
Pros
-
Event history tracks lock/unlock activity alongside motion and doorbell events, and some logs identify the user and method (fingerprint, code, app). This makes it useful for monitoring comings and goings.
-
A handful of reviews reference durability/security testing or certification, suggesting solid resistance to casual forced-entry attempts. Detailed pick/drill ratings are not commonly discussed.
-
Unlocking is described as snappy via fingerprint, and app-based control is responsive (often requiring a deliberate press-and-hold). Overall speed is commonly cited as a top strength.
-
Sharing and user roles are flexible, with admin vs limited access frequently mentioned. Code management can often be done remotely, while fingerprints still require local enrollment at the lock.
-
Most installs are described as 10–20 minutes with basic tools and clear in-app guidance. Common friction points are strike-plate fit and carefully routing/connecting the two cables.
-
Auto-lock is timer-based and highly configurable (seconds to minutes) with optional schedules and one-touch locking. Multiple reviewers describe it as reliable once calibrated.
-
Fingerprint unlock is repeatedly praised for speed and accuracy, including tolerance for imperfect finger placement after multi-angle enrollment. A minority of reviewers still note occasional misses with wet or sweaty fingers.
-
The exterior unit is often described as premium and metal-forward, with several reviews referencing BHMA-style durability claims or certification. Overall impressions trend sturdy and well-built.
-
Many sources describe IP65-style weatherproofing and good rain tolerance, but at least one reviewer suggests a lower water-resistance rating. A protected/covered door install is the safest bet for harsh exposure.
-
Across reviews, basic locking/unlocking reliability is high across fingerprint, keypad, app, and voice methods. Battery constraints and door fit are more common pain points than mechanical reliability.
-
PIN management is a strong point: multiple codes, schedules, temporary/one-time access, and scramble entry for privacy are all highlighted. Reviewers frequently mention it as especially useful for guests, workers, or families.
-
Motor actuation is generally described as smooth and fairly quiet, and manual thumb-turn use is also easy. Few reliability complaints target the motor itself.
-
The matte/metal finish is widely liked for its premium look and reduced smudging, and initial impressions of coating durability are positive. Long-term wear is not deeply documented in the reviews.
-
Reviewers generally found the Eufy Security app quick to set up and stable day to day, with lock controls, live view, power modes, and event history in one place. Sharing and role-based access are also frequently praised.
-
Wrong-try protection can temporarily lock out fingerprint/PIN entry after repeated failures, and settings let you choose thresholds and lockout duration. It is commonly framed as a practical anti-tamper measure.
-
Remote lock/unlock and live view from the same app are recurring highlights, making it easy to grant access or check the doorstep while away. Reviewers generally report smooth operation once on stable Wi-Fi.
-
The hidden key cylinder and emergency USB-C power provide strong fallbacks if the battery is depleted. Multiple reviewers highlight these as reassuring backup entry options.
-
Doorbell presses and person/motion alerts are often near-instant, though speed can vary with network conditions and settings. Reviewers frequently trust notifications due to human-only modes and fewer false alerts.
-
Wi-Fi connectivity (typically 2.4 GHz) is central to remote access and alerts, and most reviewers report stable performance even on crowded networks. Setup may require sticking to 2.4 GHz during pairing.
-
The lock works standalone with built-in storage, and HomeBase 3 pairing is optional for expanded AI features and storage/chime behavior. Most reviews position the hub as an enhancement, not a requirement.
-
Voice commands via Alexa or Google are supported for locking/unlocking and are generally described as convenient. Some reviewers wish for broader smart-speaker chime options beyond the supported ecosystems.
-
The touch interface is easy to use for PIN entry and status, but the always-off backlight can make first-time nighttime interaction less obvious. Once awake, inputs are typically responsive.
-
The touch keypad is generally responsive and supports scramble PIN entry, but visibility at night can be weaker until you tap to wake the backlight. A few reviewers also note visitors may not immediately realize the doorbell button is on the lock.
-
Alexa and Google Assistant support is commonly mentioned for voice control and chime/alert routing, and some reviews mention Apple Watch-style control. At least one reviewer notes no HomeKit support, and broader standards like Matter/Thread are not emphasized.
-
Bluetooth is used during setup/pairing and is also mentioned as an alternate unlock or connectivity path in some reviews. It is generally treated as a helpful fallback rather than a primary daily method.
-
Firmware updates are available and straightforward to apply, but reviewers do not report major new capabilities arriving via updates. Updates are mainly framed as maintenance and refinement.
-
The removable 10,000 mAh pack and USB-C charging are convenient, and an external USB-C emergency power option plus a physical key reduce lockout risk. Real-world battery life varies widely by motion recording settings and traffic, ranging from a few weeks in high-activity surveillance setups to several months in lighter or battery-saver modes.
-
The included hardware fits common deadbolt standards and the bolt is adjustable, but strike-plate sizing can require minor door-frame work. Some reviewers reused an existing strike plate successfully when alignment was good.
Cons
-
Reviews mention a one-year warranty and accessible customer support channels, but outcomes vary. One battery-drain case included support troubleshooting without a clear long-term fix.
-
Best results come on standard doors without screen/storm doors; deep jambs and off-angle approaches can limit the lock-mounted camera view. Some reviews also note specific spacing/fit requirements and that certain door setups force compromises.
-
Value depends heavily on whether you use the camera/doorbell features: when you do, subscription-free recording and all-in-one convenience can justify the price. If you disable recording to protect battery, several reviewers argue a simpler (cheaper) smart lock makes more sense.
-
Several reviews note the cylinder cannot be rekeyed, which can be inconvenient if you want one key across multiple locks. Some suggest using a locksmith for additional copies if you need more than the included keys.
-
The camera side is often described as lacking a dedicated security siren or spotlight; the main audible output is the doorbell/chime and lock tones. Some reviewers found the built-in ringing/alerts surprisingly loud, but it is not a deterrent alarm.
-
Several reviewers explicitly note the lack of a true open/closed door sensor, so auto-lock behavior is time-based rather than position-based. A few call out door-sense as a missing feature they would like added.
FAQ
How often will I need to recharge the battery?
It depends heavily on how much motion recording you enable and how busy your door is. Reviews range from needing a recharge every few weeks with active surveillance to several months with lighter traffic or battery-saver settings.
Do I need a HomeBase hub for it to work?
No. It can run on its own with built-in storage, and pairing to HomeBase 3 is optional for expanded AI features and storage/chime behavior.
Will it work on a door with a screen or storm door?
Many reviewers caution that screen or storm doors can interfere with the camera view and usability, so it is safest on a standard door without an additional outer door.
Can I rekey the lock cylinder to match my existing keys?
Multiple reviews note the cylinder is not rekeyable. If you want additional physical keys, plan on getting duplicates cut rather than rekeying the lock.
Is the fingerprint reader reliable in real use?
Most reviewers describe it as very fast and accurate after multi-angle enrollment. A few mention occasional misses with wet or sweaty fingers, but overall satisfaction is high.
