Compare eufy Video Smart Lock S330 vs Google Nest x Yale 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.

Reviewers consistently liked the event history and activity timeline, which showed lock use, code use, and who came or 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 Nest app was usually praised as simple and capable, though one review reported early crashes and hangs during setup and control.

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 was a reliable strength, especially with Home/Away Assist or configurable delay options, but it does not auto-unlock.

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.

Door backset and latch fit matter: the lock can fit standard setups, but reviewers stress checking measurements and alignment first.

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

Battery coverage was strong, with AA batteries lasting around a year or longer and 9V emergency power available when depleted.

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

Bluetooth-style proximity unlocking was a weakness because reviewers noted the lock lacks approach-based or Bluetooth auto-unlock behavior.

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

Build quality was generally strong, with reviewers calling the hardware sturdy, sleek, solid, stylish, and high quality.

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

Nest camera and doorbell ties were useful inside the Nest app, but reviewers wanted tighter Hello/video-feed integration.

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 evidence was negative: reviewers wanted a door sensor and noted auto-lock could throw the bolt while the door was open.

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

Deadbolt fit was mostly standard-door friendly, but several reviewers had to adjust frames, holes, or strike plates for smooth operation.

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

The lock reuses the door conceptually as a deadbolt replacement and can preserve the doorknob, but it replaces the existing deadbolt hardware.

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

Feature-update evidence was mixed but promising, with Google Assistant and Nest integrations described as arriving or promised through software.

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

Finish evidence was limited but positive, supported by finish options and a lifetime limited warranty for finish and mechanical issues.

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

Geofencing worked for Home/Away auto-lock, but reviewers criticized the absence of GPS or proximity auto-unlock.

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

Guest codes were a major strength, with expiring, scheduled, or temporary codes praised, though one test saw frequent keycode-generation errors.

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 Nest Connect or Nest Guard is central to the experience; reviewers accepted it but consistently flagged it as a required extra hub.

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

Installation was usually straightforward with app or voice guidance, but several reviewers needed alignment, frame, or setup troubleshooting.

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 or installation detection appeared useful when the bolt got stuck, though evidence was mostly tied to setup and alignment issues.

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

Key override reliability was weak because the lock has no physical key; reviewers relied instead on keypad access or 9V emergency power.

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

The keypad was convenient and glove-friendly, but some reviewers disliked the required checkmark step or found touch feedback inconsistent.

Keyway quality scored poorly because there is no traditional keyway or physical key path to evaluate.

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

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

The locking motor was smooth and quiet, with chimes or audible confirmation and one review calling it among the quietest locks tested.

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

Locking reliability was one of the strongest themes, with multiple reviewers reporting dependable locking and unlocking once installed correctly.

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

Notifications were strong, with reviewers receiving alerts for lock events, battery status, offline status, and failed lock behavior.

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

Physical resistance evidence was positive, from ANSI Grade 2 mentions, sturdy construction, and stronger strike-plate screw installation.

Pick resistance was supported by the keyless design and fingerprint-resistant touchscreen, but drill resistance was not directly evaluated.

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

Remote access was a core advantage through the app once Nest Connect or Nest Guard enabled internet connectivity.

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

Security features centered on privacy mode, keypad disabling, passcode limits, tamper or wrong-code alerts, and Grade 2 hardware rather than encryption details.

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

Smart-home integration was the main tradeoff: it works best in Nest, but Alexa, HomeKit, SmartThings, IFTTT, and Z-Wave support were limited or absent.

Tamper detection had direct evidence from CNET, which noted alerts for tampering and repeated incorrect password attempts.

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

The touchscreen looked premium and lit up clearly, but some reviewers found it resistive, fiddly, or lacking button feedback.

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

User access management was generally strong with scheduled, expiring, and revocable codes, though one review hit app errors during sharing.

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 depended heavily on the Nest ecosystem: reviewers saw the lock as pricey but worthwhile for Nest users who prize reliability.

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

Voice control was mixed across review timing: some reviews found no assistant support, while later evidence described Google Assistant lock-only support.

Warranty and support evidence was positive but sparse, with warranty coverage and Nest Pro installation support mentioned.

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

Weather resistance was supported by wide temperature ratings, glove use, and reviewers contrasting it with conventional locks freezing.

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 was indirect through Nest Connect or Nest Guard, and reviewers sometimes reported distance or connection caveats.
