Compare eufy Video Smart Lock S330 vs SwitchBot Lock Ultra

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.

Reviewers who mentioned logs found useful app-level history, including operation logs and local unlock logs that show who used the lock.

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

Evidence is limited but positive: reviewers noted a loud keypad speaker and measured lock noise around the mid-50 dB range.

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 is generally described as easy, smooth, and full of controls, though one reviewer wanted clearer feature explanations and hub quality affects responsiveness.

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 configurable and often useful, but it is context-dependent: lift-to-lock doors, sticky doors, and door-sensor errors can undermine it.

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

The Keypad Vision includes a failed-attempt lockout pattern, temporarily disabling access after repeated failed attempts.

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

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

Battery performance is a major strength, with rechargeable packs, 9-12 month estimates, backup batteries, and emergency power repeatedly praised.

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

Bluetooth works as the default local connection, but reviewers repeatedly note that it can slow phone control, reduce range through doors, and require a hub for more.

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

Build quality is broadly strong, with metal or alloy construction and a sturdier, more refined feel, though one reviewer disliked the side latches.

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

The Keypad Vision’s face unlock is often fast and convenient, with some doorbell/scanning benefits, but lighting, positioning, or facial-recognition quirks caused issues for some.

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 support is useful for ajar status, alerts, and auto-lock decisions, but one reviewer found the magnetic sensor unreliable.

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 compatibility is one of the product’s biggest strengths, covering many deadbolts and unusual lock types, though adapter fit is not universal.

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

Reviewers consistently valued the retrofit design because it keeps the exterior lock, existing deadbolt, and original keys in use.

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

Evidence is limited but favorable, with one reviewer seeing firmware fix a face-registration issue and another praising SwitchBot’s update record.

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

Fingerprint support is a strong backup entry method and usually quick, though one reviewer reported intermittent scanner non-response.

Finish evidence is limited; reviewers liked the matte design and noted anti-UV/PVC durability features on the exterior keypad.

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

Geofencing is the weakest repeated smart feature, with several reviewers calling it beta or inconsistent despite the broader auto-unlock promise.

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

Guest access is robust, with permanent, temporary, one-time, and emergency code options, though scheduling controls could be more flexible.

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

A hub or bridge is the main ecosystem caveat: local Bluetooth works, but Matter, Wi-Fi, remote control, and deeper integrations commonly require extra hardware.

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

Installation is widely praised as quick and beginner-friendly, but unusual locks, adapters, and door setups can still complicate the process.

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.

Jam handling exists through emergency unlock or boosted motor power, but stuck-door scenarios may require recalibration and remain door-dependent.

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

Key override remains a key benefit of the retrofit design, although some key-operated lock setups can limit outside key use.

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

The keypad ecosystem is a major advantage, adding PIN, NFC, fingerprint, and face options; several reviewers considered a keypad essential.

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

Locking speed is usually improved and quick, especially via keypad, but phone/Bluetooth control can sometimes be slower.

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

Motor performance is frequently praised for stronger torque and quieter operation, with a caveat that slow/night modes may reduce power on sticky locks.

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

Core lock reliability is generally strong, with many successful tests, though some edge cases appear with night mode, third-party control, or door alignment.

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

Notifications are a strong feature, covering lock events, open-door states, battery warnings, and smart-home alerts depending on setup.

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

The lock does not meaningfully upgrade physical attack resistance; reviewers emphasized that the existing cylinder remains the physical-security baseline.

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

Remote access works well when bridged through a hub, doorbell, or cloud-supported setup, enabling vacation or away-from-home control.

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

Security features are well covered, including local biometric storage, AES-style encryption, anti-code-peeking, emergency methods, and face anti-spoofing claims.

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

Smart-home integration is broad through hubs and Matter bridges, covering Apple Home, Alexa, Google, Home Assistant, SmartThings, and automation use cases, but third-party reliability varied.

Tamper evidence is limited but present, with the Keypad Vision offering an anti-tamper mechanism and reviewers noting tamper alerts.

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

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

User management is strong, with many profiles and entry types, but one review wanted more granular scheduling for access methods.

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 generally viewed positively because the lock is fairly priced for its feature set, though keypad bundles can approach competing full-lock prices.

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

Voice control is supported through smart-home integrations and hubs, including Alexa, Google, Siri/Apple Home references, but it is not standalone.

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

Weather resistance is strongest for the Keypad Vision, with IP65, rain, wind, and cold-operation evidence, though very low temperatures affected face recognition in one test.

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 is available through a hub rather than directly in the lock, enabling internet and remote control when the hub is present.
