Compare eufy Video Smart Lock E330 vs eufy Video Smart Lock S330

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.

Access/activity logging is a practical strength in real use: reviewers mention seeing who unlocked/locked and, in some cases, which fingerprint/user performed the action.

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.

The app is consistently described as clean and feature-rich, with detailed control over access, detection, notifications, and power modes. A recurring critique is that troubleshooting (especially calibration guidance) could be clearer, and some wanted phone-based tap/NFC unlock.

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.

Auto-lock is commonly praised for peace of mind and flexibility (including short delays and schedules). Some reviewers cautioned that auto-lock can be risky if your door isn’t reliably closed/aligned or if door state detection is imperfect.

Wrong-try protection appears well implemented, letting owners lock out further attempts after repeated bad fingerprints or PIN entries.

Wrong-try protections are commonly described (lockdown/timeouts after multiple incorrect entries), helping reduce brute-force attempts and adding practical security beyond basic PIN entry.

The adjustable deadbolt and removable fit pieces help it adapt to common backset and bore variations on standard doors.

Backset support is described as adjustable to common sizes (2 3/8 in and 2 3/4 in), which helps it fit typical deadbolt door prep.

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.

Battery life is a highlight: the 10,000mAh rechargeable pack is repeatedly described as lasting months, with long-term users charging only a few times per year when tuned (for example, human-only motion). Charging can take hours and you may need to supply your own USB-C power gear.

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.

Bluetooth is commonly mentioned as part of the lock-to-bridge communication path. Reviewers generally describe it as functional, primarily as an invisible link in the overall system.

Build quality is generally rated highly, with reviewers calling the exterior solid, premium-looking, and well made for a lock-camera combo.

Build quality is widely described as heavy-duty and mostly metal, but it is also frequently called large/bulky. One expert review wanted a bit more robustness to make it an easy, universal recommendation.

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.

Reviews indicate the E330 lacks true door-open and door-closed sensing, so auto-lock relies on timers instead of confirming the door position.

Door state awareness appears mixed: at least one reviewer warned the lock may not reliably know whether the door is open or closed, which matters if you rely heavily on auto-lock behaviors.

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.

Door fit is usually straightforward, but some doors may need extra attention: shallow strike-plate depth can trigger calibration failures, and tight tolerances mean misalignment can prevent reliable locking.

Some installations reuse the existing strike plate or fit the current bore cleanly, but others require minor modification or a new strike fit.

At least one installation guide notes you may be able to reuse existing deadbolt hardware if it fits flush, reducing the need to replace every component.

At least one long-term reviewer highlighted meaningful feature additions via updates, such as unlocking directly from a live-view screen on supported cameras, improving day-to-day usability.

Fingerprint entry is one of the product's clearest wins, repeatedly described as fast, accurate, and the preferred way to unlock.

Fingerprint performance is polarizing: several owners describe it as among the fastest and most accurate they have used, while one expert reviewer struggled with repeated reads and wished for clearer activation feedback (lighting).

Lineup comparisons indicate the E330 does not offer the location-based auto features found on higher-tier Eufy models.

Guest access is flexible, with permanent, temporary, scheduled, and one-time code options that reviewers found genuinely useful.

Guest access options are robust, including temporary or scheduled PIN codes and app-based access. Scramble passcode and other convenience/security options are frequently cited.

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 required plug-in chime/bridge is a core part of the experience: it enables remote connectivity and local storage, and many liked having a loud indoor chime. Downsides include extra setup steps and needing to provide your own microSD card.

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.

Most reviewers found installation similar to other full deadbolt replacements and generally manageable, but a few called out real-world friction: needing a second set of hands, long firmware updates, and careful mechanical alignment to avoid errors or motor strain.

Calibration and error states can present as jam-related warnings in the app for some installs, even when the deadbolt feels physically secure, creating nuisance alerts rather than true mechanical jams.

The hidden physical key and external USB-C emergency power option give the E330 credible backup access if the battery runs down.

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.

The keypad is generally considered easy and reliable for daily use, with extra security options like scramble passcodes. One reviewer noted occasional wake-up/tap sensitivity issues before the keypad became responsive.

The physical key backup is useful, but the cylinder cannot be rekeyed, which several reviewers see as a practical downside.

Locking and unlocking are generally quick, especially by fingerprint, with several reviewers describing the response as near-instant or sub-second.

When the biometric reader works well, unlocks are described as extremely fast. However, experiences vary: some testers reported repeated attempts needed on the fingerprint sensor, while others called operation instant and consistent.

Limited direct commentary suggests the motor is reasonably quick and quiet, but this is not as heavily discussed as fingerprint speed or battery drain.

The motor is sensitive to resistance: if the deadbolt/strike alignment is off, reviewers warned the motor may struggle or fail to complete a lock cycle. With good alignment, long-term users reported stable performance.

The lock mechanism itself is consistently dependable in reviews, with few complaints about failed locking or unlocking once properly installed and calibrated.

Locking reliability is strong for many owners (including long-term use), but it is not universally flawless. Reported weak spots include finicky alignment/calibration states and occasional inconsistencies with certain external controls (like one-touch locking).

Notifications are a strong point, with repeated praise for fast alerts from motion events, doorbell presses, and lock actions.

Notifications are configurable and usually fast, but not perfect: a few reviewers saw delayed starts to recorded events, occasional missed motion/loitering triggers, or tradeoffs between faster alerts vs alerts that include thumbnails.

Evidence is limited but positive, including BHMA-related claims and durability figures that suggest a sturdier-than-average smart lock build.

Remote locking, unlocking, live view, and answering the door from the app all work well and are central to the product's appeal.

Remote access is repeatedly described as convenient and reliable, including locking/unlocking from anywhere and checking lock status. Several reviewers highlighted using it for guests, contractors, or deliveries.

Security and privacy discussion centers on local storage and app behavior; one reviewer noted an on-screen encryption message before video streams to the bridge. Overall, the product is framed as privacy-leaning due to non-subscription local storage, with some mention of broader brand scrutiny.

Integration is good but not universal: Alexa and Google are commonly supported, HomeBase 3 adds more capability, and HomeKit support is notably absent.

Smart-home integration is limited compared to ecosystems that prioritize Apple: reviewers consistently note Alexa and Google support, but no Apple HomeKit, Matter, or IFTTT.

The touch-sensitive keypad is responsive and modern, though nighttime discoverability is not as polished as on some dedicated doorbells.

Touch controls are usually described as responsive and backlit, but at least one expert review reported needing multiple taps to wake the dark touchscreen at times.

User management is robust, supporting admins, shared users, remote passcode assignment, and sizeable limits for codes and fingerprints.

User management is broadly praised, including multiple users, fingerprints, and configurable access windows. Reviewers emphasized that it’s easy to add or adjust access in the app.

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.

Value is framed as strongest when the price is closer to the low-to-mid $300s, since it combines multiple devices and includes the chime/bridge. At full price near $400, reviewers still call it feature-rich, but expectations rise for perfect reliability and broad ecosystem support.

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.

Voice control works through Alexa and Google Assistant in supported setups, including lock/unlock commands and, in at least one review, routines tied to doorbell events.

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.

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.

Weather resistance is presented as strong on paper (including an IP65 rating in one review), and no reviewer reported weather-related failures in the provided transcripts.

Wi-Fi performance is typically stable once connected, with fast remote access and alerts, but setup expects a 2.4 GHz network.

Wi-Fi is tied to the required bridge and is noted as 2.4GHz in at least one expert review. In general, connectivity is described as stable, with one review calling out distance guidance between lock, chime/bridge, and router.
