Compare eufy Video Smart Lock S330 vs Desloc D110 Plus 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.

Event history and logs are repeatedly mentioned for locks, unlocks, activity, users, and alarm events.

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 is generally considered straightforward for status, access, settings, and control, with one reviewer only calling the overall feature set adequate.

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 usually convenient, but missing door sensing makes it risky when the door is open.

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

Failed-attempt protection is supported through wrong-try/security lockout evidence, and later firmware reportedly added repeated-unlock protection.

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

GearBrain specifically listed support for 2-3/8-inch or 2-3/4-inch backsets.

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

Battery life is commonly described around four AA batteries and six months, with some concern about Wi-Fi drain before updates.

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

Bluetooth appears as setup or local connectivity support rather than a headline feature.

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

Most reviews describe solid build, BHMA/IP-rated durability, or good build for the price; PCWorld was the main outlier on questionable construction.

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.

Reviewers agree it lacks a door sensor, so time-based auto-lock can throw the bolt even if the door is 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.

Evidence supports standard U.S. deadbolt sizing and auto left/right door detection, while one reviewer cautioned against very thick doors.

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

Existing-hardware reuse is mixed: one reviewer reused an existing deadlock, while another said the lock replaces the entire deadbolt.

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

Firmware updates improved Wi-Fi stability, power usage, passcode masking, auto-lock behavior, and feature availability.

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

Most reviewers found fingerprint access fast or accurate; PCWorld was the main negative outlier with hit-and-miss scans.

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

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

Temporary, one-pass, scheduled, and Airbnb-style access are well-supported across reviews.

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

Reviewers repeatedly emphasize direct Wi-Fi operation without a separate hub or gateway.

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

Most reviewers found setup simple, with app-guided onboarding and auto door-hand detection, but PCWorld and GearBrain reported hardware, cord, or overtightening problems.

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.

Multiple reviewers confirm a mechanical key or keyway backup, and several frame it as a reliable fallback if power or electronics fail.

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

Keypad evidence is mixed: one review praised responsiveness and lighting, another said it was slow to wake, and others noted backlit or passcode features.

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

Fingerprint and voice/app responses are often described as quick, snappy, or instant, though one reviewer found it slower than other locks.

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

Motor evidence is mixed: PCWorld found operation smooth and quiet, while GearBrain warned overtightening could make the bolt struggle.

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

Most hands-on reviewers reported reliable operation, including no jamming, stable 90-day use, and successful remote or app use.

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

Reviewers saw lock status, user, and alarm notifications, though one noted emergency emails went to spam.

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

BHMA Grade 3, cycle, salt-spray, impact, and residential-security claims support basic physical durability, not premium security.

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

Remote locking, unlocking, monitoring, and code management are consistently supported when Wi-Fi is enabled.

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

Evidence supports anti-peep PINs, failed-attempt lockout, anti-hijack alerts, and encrypted biometric storage.

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

Alexa and Google support is consistent, but reviewers repeatedly flag missing HomeKit, Matter, IFTTT, or deeper security-platform integration.

Only one review clearly mentions a tamper-triggered anti-hijack alarm, so evidence is limited.

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

The touch/display experience is generally useful for keypad entry, status, battery, and visual feedback, but it remains basic.

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

User management is one of the strongest areas, with reviewers repeatedly citing user profiles, fingerprints, PINs, schedules, and permissions.

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.

Most reviewers saw strong value or sub-$100 appeal; PCWorld was the clearest dissent, saying compromises undercut the value.

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

Voice control through Alexa and Google is directly supported, with several reviewers describing successful or seamless use.

Formal warranty was not reviewed, but support evidence is positive through repeated firmware updates and customer-responsive enhancements.

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

Reviewers repeatedly cite IP-rated dust and water resistance or durability testing, though one review called the IP54 rating tame.

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

Built-in Wi-Fi is a central strength, supporting remote status/control and later firmware improvements.
