Compare eufy Video Smart Lock S330 vs ULTRALOQ Bolt Fingerprint 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.

Access logs are supported by multiple reviewers, including event timelines and logs showing who entered, exited, and how the lock was used.

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 app experience is mixed: several reviewers found it simple or easy, while one reported bugs, unreliable connection, and a need for software improvements.

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 a major supported feature and usually worked well, though one reviewer could not enable it reliably in the U Home app.

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

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

Backset adjustability is directly shown in installation walkthroughs, including standard 2-3/8-inch sizing and twist/expand adjustment.

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

Battery evidence centers on eight AA batteries and a claimed roughly one-year life, though reviewers generally had limited long-term testing.

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

Bluetooth is supported as part of the lock's connectivity and HomeKit behavior, but Bluetooth-only control can mean standing near the lock or slower Apple Home response.

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

Build impressions are mostly positive, with zinc alloy, sturdy feel, better materials, and higher-quality plastics noted across reviews.

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.

Door-sense is frequently supported by the included sensor, open/closed status, notification behavior, and auto-lock prevention when the door is ajar.

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 favorable for standard deadbolt setups, but reviewers note this is a full lock replacement rather than a retrofit device.

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

Existing hardware reuse is limited: one reviewer reused the strike plate, another was slowed by trying to reuse hardware, and Tom's Guide stresses full lock removal.

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

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

Fingerprint access is the strongest consensus feature, repeatedly described as fast, accurate, responsive, and reliable across nearly every review.

Finish durability evidence is limited to one reviewer noting the updated keypad material should hold up better than an older rubber keypad.

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

Geofencing and auto-unlock are useful but inconsistent: several reviewers liked hands-free arrival, while others found it slow or not always reliable.

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

Guest access is a clear strength, with one-time, temporary, scheduled, and code-based access supported for neighbors, cleaners, or recurring users.

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 requirements vary by model and platform, ranging from no added Wi-Fi hub to needing a Matter hub or optional bridge for certain remote setups.

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

Reviewers broadly found installation easy or straightforward, often taking only minutes on compatible deadbolt doors, with one reviewer slowed by attempting to reuse hardware.

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.

The physical key backup is consistently present and usable, though one review warns there is no emergency power port so keys matter.

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

The keypad receives strong feedback for tactile physical buttons, anti-peep code entry, and responsive operation rather than a smooth touchscreen interface.

Mechanical keyway quality is a weak point in the lock-picking review, which describes an odd Quickset-style blade and Schlage-like bow mismatch.

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

Speed is strong for fingerprint and app use in several reviews, but one reviewer saw slow app connection and PCWorld found Matter actions a few seconds slower.

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

Only PCWorld directly evaluated the motor, and it was sharply negative because the Matter unit made a grinding, whining sound.

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

Locking reliability is mostly strong in hands-on tests, but one reviewer reported app commands failing and another noted Apple Home could be slow.

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

Notifications are well covered, including smart notifications, user-specific alerts, and open-door or locked/unlocked status alerts.

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 mixed in scope, with ANSI Grade 1 claims and bump resistance weighed against lock-picking concerns.

Pick/drill resistance evidence comes only from the lock-picking review, which criticized anti-pick features while praising bump resistance.

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

Remote access can be useful through Apple/HomeKit, Wi-Fi, or apps, but evidence is split because one reviewer found remote access impossible when Wi-Fi failed.

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

Security-feature evidence centers on anti-peep/random digit PIN entry and PIN obfuscation; reviewers did not directly test encryption.

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

Smart-home integration is broad, with HomeKit, Alexa, Google, SmartThings, IFTTT, Matter, and Apple Home repeatedly mentioned, but Home Assistant and Home Key gaps remain.

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

Touchscreen evidence is mostly negative or indirect because reviewers emphasize tactile buttons instead of digital touchscreens, and one notes no Apple Home Key support.

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

User access management is robust, with up to 50 users, admin/normal/temporary roles, app access, PINs, and fingerprint assignment.

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 depends on priorities: reviewers saw many features for the money, but several noted a high price, missing Home Key, Wi-Fi limitations, or motor noise.

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

Voice control works well in several demonstrations with Siri, Alexa, or Google, though one reviewer ended with a Siri command that did not respond.

Support evidence is limited to one reviewer contacting U-tec, which reportedly appreciated the feedback and escalated the issue internally.

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

Weather resistance is supported by repeated IP65 references, including all-season protection and resistance to rain, dust, and extreme temperatures.

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 support is version-dependent and mixed: some reviews praised built-in Wi-Fi, while one had unreliable Wi-Fi and PCWorld's Matter unit lacked integrated Wi-Fi.
