Compare eufy Video Smart Lock S330 vs Yale Assure Lock 2 Smart Lock

Reviewers who discussed logs found useful entry history, including how the lock opened and which fingerprint was used, with one transcript explicitly describing an activity log.

Activity logging is one of the clearest strengths, tracking lock, unlock, manual, code, app, and DoorSense activity so owners can see who came and went.

The included chime can get loud enough for household alerts across rooms or floors, though reviewers discussed chime volume rather than a separate siren.

The app was generally praised as smooth, clean, user-friendly, and feature-rich, with live video, settings, and remote controls accessible from the phone.

The Yale app is usually described as organized or easy enough for lock control and codes, but reviewers also reported slow loading, old design, and connection glitches.

Auto-lock was repeatedly seen as a useful peace-of-mind feature, with timing and schedule controls, although one reviewer warned it may lock when the door is open.

Auto-lock is widely supported and often useful with DoorSense or timers, but a few reviewers saw inconsistent behavior when the door was not detected correctly.

Wrong-try protection and passcode lockout were clearly supported, giving the lock a configurable response after repeated failed attempts.

Wrong-code protection appears in the keypad settings, with reviewers noting shutdown times, wrong-code limits, and temporary keypad lockout behavior.

Backset support is well documented for common 2 3/8-inch and 2 3/4-inch sizes.

Backset support is standard for common 2-3/8-inch and 2-3/4-inch setups, but one Touch reviewer warned that longer-than-average backsets are unsupported.

Battery feedback was strongly positive overall, with multiple reviewers citing several months of use, USB-C charging, and only occasional recharges.

Battery life is the most repeated weakness, especially with Wi-Fi, with reviewers citing short life, limited battery visibility, and late low-battery warnings.

Bluetooth is present through the included bridge, which PCMag says contains both Wi-Fi and Bluetooth radios.

Bluetooth is consistently supported and often useful for local setup and control, with some reviewers noting Bluetooth-only models trade remote features for longer battery life.

Build quality was consistently described as sturdy, metal, heavy-duty, or durable, although the hardware is also physically large.

Build feedback was mostly positive, with reviewers praising the compact, sturdy, premium-feeling hardware, though a few noted hollow-feeling construction or a scuffed finish after a fall.

Camera and doorbell performance were usually praised for 2K clarity and useful detection, but a few reviews reported missed, delayed, or weaker night events.

Door-sense style features are mixed: one review praised leaving detection, while another said auto-lock did not know whether the door was open or closed.

DoorSense is valuable for open, closed, and ajar awareness, though installation can require drilling and a few reviewers reported calibration or matching-design complaints.

Deadbolt fit is the biggest installation caveat: it replaces a standard deadbolt but can be sensitive to strike-plate depth, alignment, and size constraints.

Door fit is generally broad for standard deadbolt doors, though reviewers repeatedly noted the need to measure thickness, bore holes, and hardware before installation.

SafeWise explicitly noted that the existing deadbolt can be reused if the Eufy deadbolt does not fit flush.

The lock replaces rather than reuses the existing deadbolt hardware, which is a drawback for shoppers who want to keep their current lock body.

At least one long-term reviewer observed a useful live-view unlocking feature added after the original review.

Upgradeability is a strong theme: reviewers noted bug fixes, firmware updates, interchangeable wireless modules, and future Matter or Z-Wave paths.

Fingerprint performance was split: several reviewers called it fast and accurate, while PCWorld had repeated recognition problems.

Fingerprint performance is the most split attribute: several Touch reviewers found it very fast and accurate, while one long-term reviewer reported persistent failures.

Finish durability evidence is limited and mixed, with one reviewer reporting the rubber finish became a little banged up during installation.

Geofencing or phone-proximity unlock was not available in the reviewed app experience; one reviewer specifically wished for it.

Geofenced auto-unlock is convenient when it works, but reviewers were split because it requires location permission, can fail, and has radius or multi-door limitations.

Guest access is a strength, with temporary passcodes, schedules, and easy programming mentioned across reviews.

Guest-code support is a standout, with temporary, recurring, scheduled, and high-capacity PIN options repeatedly praised for families, dog walkers, cleaners, and rentals.

The bridge/chime is central to the system: reviewers described it as included, useful for indoor chimes and storage, and in one case mandatory.

Hub and module needs vary by configuration; some Wi-Fi setups avoid a separate bridge, while Alexa, Google, Matter, Z-Wave, or remote access can require the right module or hub.

Installation was mostly manageable and often easy, but several reviewers noted alignment, strike-plate depth, or two-handed handling challenges.

Most reviewers found installation manageable on standard doors, with several calling it quick or app-guided, but others hit fit, DoorSense, calibration, or careful-alignment issues.

Jam detection can be frustrating when calibration or strike-plate depth is off, with one reviewer saying the app kept showing jammed despite a secure bolt.

Key backup is well covered: reviewers repeatedly noted the hidden or included physical key option for emergencies.

Backup entry depends on the model: keyed versions provide a physical key, while keyless versions rely on a 9V battery contact as the fallback.

The keypad generally worked well and supports PIN entry, though one review found the touchscreen sometimes needed extra wake-up taps.

Keypad feedback is mostly positive for visibility at night and easy code entry, but several reviewers disliked needing to tap the Yale logo and one reported keypad failure.

Lock and unlock speed was strong in favorable tests, especially through fingerprint access, with instant or very quick operation reported.

Locking and unlocking speed was usually praised, with reviewers describing responsive Bluetooth operation, quick keypad opening, and automatic unlocking at close range.

The motor can be sensitive to deadbolt alignment; one review warned it may fail to lock if the motor struggles.

The motor and deadbolt action drew positive comments for smooth, solid movement and audible lock/unlock feedback.

Locking reliability ranged from flawless or year-long solid use to sensitivity when alignment was imperfect or one-touch locking failed.

Reliability is generally good for basic locking and unlocking, but app connection delays, Bluetooth setup hiccups, and one long-term fingerprint issue keep it from being flawless.

Notifications were generally fast and useful for activity, motion, lock/unlock events, and thumbnails, though one review noted delayed motion recording.

Notifications are useful for lock events, ajar warnings, and user activity, but reviewers also reported late low-battery warnings, missing alerts, and noisy Wi-Fi disconnect notifications.

Physical resistance was not attack-tested, but the lock offers extra screws for added security and reviewers described sturdy hardware.

Physical security evidence is positive but mostly specification-based, with reviewers citing Grade 2 certification, sturdy construction, and key-free resistance to forced picking.

Pick resistance is only directly supported for key-free versions, where one review says the absence of a keyway prevents picking or forced opening through that route.

Remote access was a clear strength, with reviewers locking or unlocking from the app, even away from home.

Remote access is a strong feature on Wi-Fi-enabled setups, letting owners lock, unlock, monitor, or share access away from home, though connectivity issues appeared in some tests.

Security features include scramble passcodes, wrong-try protection, and an encryption message, while one review also mentioned broader Eufy privacy concerns.

Security features include local fingerprint storage, AES encryption, code-hiding or PIN-lockout options, and account protections, but evidence focuses more on features than testing attacks.

Alexa and Google support were consistently reported, while reviewers also consistently noted missing HomeKit, IFTTT, and Matter support.

Smart-home support is broad across HomeKit, Alexa, Google, SmartThings, Z-Wave, Zigbee, Wi-Fi, and future Matter paths, though exact support depends on the model or module.

Touchscreen and touchpad feedback was mixed, ranging from PCMag's responsive touchpad to PCWorld's wake-up issues.

Touchscreen models look sleek and work well indoors or at night, but multiple reviewers found the screen or numeric keypad hard to read in direct sunlight.

Two-factor authentication is directly supported in one review, which says the app requires a strong password plus two-factor verification.

User access management is strong, with high user/fingerprint limits, individual codes, and easy additional-user enrollment.

User access management is strong, with owner/guest roles, app access, entry-code access, fingerprint access, and scheduled permissions appearing across reviews.

Reviewers generally found the price reasonable for the all-in-one lock, doorbell, camera, local storage, and no-fee value, while still calling it pricey.

Value is context-dependent: reviewers liked the feature set and midrange pricing, but several called higher Wi-Fi or Touch configurations expensive or harder to justify.

Voice control works through Alexa and Google according to multiple reviews, but Apple ecosystem support is absent.

Voice control works through supported ecosystems such as Siri, Alexa, and Google Assistant, but security PIN prompts and module requirements can make it less seamless.

Support evidence is negative and limited to one long-term reviewer whose persistent fingerprint problem was not resolved or exchanged by Yale support.

Weather resistance is supported by an IP65 waterproof rating and operating-temperature claims in the reviewed materials.

Weather and temperature evidence is favorable, including operating-temperature claims, IPX5 coverage, and real use in very cold conditions.

Wi-Fi works through the bridge and supports remote use, but reviewers noted 2.4GHz-only setup and dependence on the bridge/chime connection.

Wi-Fi enables remote access and broader integrations, but it also drives the main complaints: battery drain, setup issues, disconnections, and occasional app connection trouble.
