Compare eufy Video Smart Lock E330 vs Tapo Smart Door Lock DL110

Keyway quality was a recurring weakness because multiple reviewers noted the lock cannot be rekeyed or needs a locksmith for extra keys.

A locksmith reviewer praised the SC1/Schlage-style keyway because it could be pinned to an existing house key without trouble.

Existing hardware reuse scored well in the one clear opinionated case, where the lock worked with an existing strike plate and the reviewer called that nice.

Existing strike reuse was a weakness in one hands-on review because the tester had to adjust the strike plate before the lock behaved correctly.

Door compatibility was a major caveat because screen doors, storm doors, deep jambs, and awkward door angles could compromise the camera or overall fit.

Door fit drew mixed evidence: the lock uses common deadbolt hardware, yet reviewers warned that door restrictions and strike/frame tolerances can matter.

Auto-lock drew strong praise for reliably relocking after a set time and reducing worry about whether the door was left unlocked.

Auto-lock was widely praised as convenient and configurable, but the PCWorld review found it could repeatedly cycle when calibration was off.

The failed-attempt lockout behavior was viewed as a strong security safeguard when someone keeps entering wrong codes or fingerprints.

Failed-attempt lockout had limited but positive evidence, with one reviewer describing automatic lockdown plus notification after suspicious attempts.

Security features such as scramble passcode and failed-attempt protections were praised as sensible, useful, and security-enhancing.

Security feature praise centered on scramble PINs and biometric app verification; reviewers did not evaluate encryption specifically.

Weather resistance scored strongly where reviewers found the lock handled rain, hot conditions, or outdoor exposure well.

Weather resistance was viewed positively, with reviewers citing stronger element protection and confidence around rain, snow, and outdoor placement.

Guest access was praised when reviewers could give temporary or remote user access without handing over physical keys.

Guest access was a strong feature for families, cleaners, technicians, and visitors, although the PCWorld review noted limits for commercial rental automation.

Reviewers who evaluated event history found it useful for checking clips and seeing who came or went, especially for family awareness.

Access logs were repeatedly praised for showing what happened, who used the lock, and when, often in a clear or categorized format.

Remote access was rated very highly because reviewers liked being able to view, unlock, greet visitors, or control the lock from the app remotely.

Remote access was a practical highlight, letting reviewers unlock or lock from another location or from a vehicle when someone needed entry.

Lock and unlock speed scored strongly in the one clear opinionated review that called the lock fast and quiet.

Unlocking speed was a major strength, with reviewers describing near-instant fingerprint or app response.

The keypad was viewed positively for reliability, passcode flexibility, and backlighting, although one reviewer treated keypad access as less preferred than fingerprint.

The keypad was generally well-liked for fast response, code entry convenience, visibility, and anti-shoulder-surfing features.

Fingerprint access was one of the strongest areas, repeatedly described as fast, accurate, responsive, convenient, and the preferred unlock method.

Fingerprint recognition was one of the clearest strengths, repeatedly described as fast, accurate, easy to enroll, and nearly instant.

User access management scored well where reviewers valued adding users, codes, and fingerprints with access rules.

User management was praised for configurable people, fingerprints, PINs, schedules, and control over who can enter.

The locking motor was praised as smooth and responsive in hands-on use.

The motor was praised as quieter and more refined than many smart locks, reducing the clunky feel some reviewers dislike.

Battery feedback was the most divided area: some reviewers liked the removable rechargeable pack, while others reported short runtime or slow charging.

Battery life was strongly praised for its large rechargeable pack and long expected runtime, with one review also noting 100% after weeks of use.

Touchscreen visibility scored poorly in the one clear opinionated review because the keypad and doorbell button were hard to find in the dark.

Touch/wake behavior was the one weak touchscreen-related point: one reviewer wished the lock lit up automatically instead of needing an initial touch.

Notifications were a clear strength, with reviewers describing alerts as nearly instant, responsive, fast, or consistent.

Notifications were praised as quick, instant, configurable, and useful for lock activity, doorbell presses, and suspicious activity.

Wi-Fi was mixed-positive: one reviewer saw fast alerts even on weak 2.4GHz Wi-Fi, while another warned experience depends on network strength.

Wi-Fi received positive but narrower evidence, with reviewers praising reliable connectivity and useful power-saving scheduling.

Smart-home integration was mixed-positive: Alexa, Google, Apple Watch, and Eufy ecosystem links were appreciated, but lack of HomeKit hurt one review.

Smart-home integration was mostly positive for Alexa, Google, and SmartThings setup, though one reviewer wanted deeper automation.

Voice control was positively received, especially Alexa integration, chime support, and hands-free unlocking through assistants.

Voice control was shown working well and was viewed positively, especially with required PIN/security steps for unlocking.

The app was consistently praised as simple, polished, and useful for setup, live view, lock control, access management, and monitoring.

The app was consistently praised as intuitive, useful, and easy to follow for setup, control, users, logs, and settings.

Value was mostly positive thanks to all-in-one convenience and savings versus higher-tier models, though one reviewer stressed that the lock is not cheap.

Value was one of the strongest consensus points: reviewers repeatedly called the DL110 unusually feature-rich for its price.

Locking reliability scored highly where reviewers focused on the smart-lock half, calling it responsive and saying it worked as advertised.

Overall reliability was strong across testing, though one reviewer’s alignment-related auto-lock issue kept it short of flawless.

Installation and setup were consistently praised as quick, easy, straightforward, foolproof, or among the easiest smart-lock setups reviewers had tried.

Most reviewers found setup quick and DIY-friendly, often around 5-20 minutes, but one reviewer found the DL110 unusually finicky when strike alignment was imperfect.

Key override reliability scored well because reviewers appreciated the hidden physical key and backup power options for dead-battery situations.

Backup key access was treated as a reassuring fallback, especially when paired with the hidden keyhole and other emergency power options.

Build quality was rated very highly, with reviewers repeatedly describing the lock as metal, sturdy, well made, durable, and high quality.

Build quality was consistently praised as substantial, sturdy, and durable, with reviewers calling it built to last or quality-feeling.

Industrial design was well liked, with reviewers calling the lock sleek, compact, sharp, premium-looking, and attractive.

Industrial design was praised for its sleek matte look, hidden backup entry, and ability to blend into a door rather than looking overly techy.

Camera and doorbell performance was generally strong, with sharp 2K video, good night vision, fast loading, and useful two-way features, though field of view and door placement limited some setups.

The built-in doorbell was generally praised as useful, integrated, loud enough, and a reason the lock feels more like a two-in-one device.

Bluetooth was valued as a useful fallback when Wi-Fi drops or is unavailable, preserving local app control.

Door-sense was weakly supported because a reviewer specifically wanted a sensor to know whether the door was open or closed.

Facial recognition was mixed: HomeBase-linked identification worked in one test, while another reviewer wanted face-based unlocking added.

Hub requirement was mixed because the lock can work without a HomeBase, but one reviewer disliked needing a separate chime when used alone.

Jam detection had limited but positive evidence, with one reviewer confirming the app produced a notification for a door-jam event.

Physical security drew strong praise from reviewers citing Grade 2/BHMA positioning and stronger resistance than many lower-grade locks.

Tamper-related alerts were treated as useful extra protection, with reviewers praising suspicious-activity alerts and the tamper alarm concept.

The matte finish earned praise for resisting fingerprints and keeping the exterior cleaner after repeated touch use.
