Comparison Summary
For an all-around front-door upgrade, the eufy FamiLock S3 Max combines palm-vein entry, a 2K video doorbell, and an indoor viewing screen; its backup batteries keep essential entry available but do not run the camera or palm scanner. The Lockin Veno Plus is a compelling alternative when fingerprint entry and 8 GB of local video storage matter more than an indoor screen, provided its specific wooden-door requirements are met. myQ Secure View offers face, fingerprint, PIN, app, and key entry alongside 2K video, but some detection and video-history features require a subscription, and its biometric methods are unavailable in Illinois and Texas. Handle-set buyers should look first at the hornbill or Nyboer designs. Check the exact kit before ordering: the eufy listing headed E331 also carries an E330/T8531 part-number reference.
Buying Guide
Sizing and Capacity
Here, sizing means door fit, camera clearance, and storage capacity—not square-foot coverage. For Lockin Veno Plus, manufacturer guidance specifies a wooden door 1⅜–2¹¹⁄₆₄ inches (35–55 mm) thick, a 2⅛-inch crossbore, a 2⅜- or 2¾-inch backset, and a rectangular latch-faceplate cutout. It also says a storm door can block the camera and is incompatible. Do not apply those measurements to another lock. The hornbill handle set lists 35–55 mm wooden doors; the Nyboer panel is intended to cover two existing holes, but its length alone cannot establish that their spacing fits. YINTIN requires a larger mortise opening. Storage capacity is a separate question: Lockin lists 8 GB locally, but gigabytes alone do not establish how many days of clips you will retain.
Feature Tradeoffs
Choose entry methods for the people who actually use the door. FamiLock S3 Max offers palm-vein entry and an indoor screen for someone who wants to inspect a visitor without opening an app. Lockin Veno Plus adds fingerprint access to palm-vein entry, while myQ Secure View offers hands-free face access where that feature is available. PINs and physical keys give guests or household members an alternative when they cannot use a biometric method. For video, distinguish free live viewing from saved footage and advanced alerts: myQ says basic live streaming and motion notifications remain available without a plan, while video history and smart detection require one. An integrated camera may cover visitors well yet miss a package set below its view or an area beyond the doorway.

Key Specs to Compare
Read a camera’s stated field of view alongside its resolution. The 180° Lockin view, 150° views on FamiLock S3 Max and myQ, and 720p Lockly camera describe different equipment; none proves what your own recessed entry will show. Check whether two-way talk, live view without a doorbell press, recorded clips, and the alerts you want are specified for the exact model. Compare connectivity by feature, too: FamiLock S3 Max supports Matter, but its camera stream does not pass through Matter; use the eufy app for video. Lockin’s Matter integration may call for a compatible controller. Built-in Wi-Fi on a listing does not mean remote controls work during an internet outage.
Setup and Handling Considerations
Before ordering, measure door thickness, backset, bore, latch-faceplate shape, and clearance around both sides of the lock. Check whether a storm door, deep trim, or nearby handle would obstruct the lens or prevent either assembly from fitting. Decide whether you are keeping your handle: the eufy, Lockin, and myQ deadbolt designs address a different installation from the hornbill and ARPHA handle sets. Nyboer proposes a one-piece replacement for two-hole setups, whereas the YINTIN mortise design calls for closer comparison with its installation dimensions and may require drilling. Confirm the exact kit contents, including a chime or spare battery, before planning the installation.
Maintenance and Longevity
A camera and lock share a power source, so plan charging around both entry and video use. The FamiLock S3 Max’s AAA backup can preserve limited lock operation when the main rechargeable battery runs down, but its palm scanner and camera are disabled in backup mode. A spare battery makes the listed myQ kit attractive if you want to swap batteries during charging; confirm it is included with that ASIN. Lockin describes a mechanical key and emergency power-bank access. YINTIN lists a key and USB-C emergency input. Treat advertised battery durations as usage-dependent, particularly if the camera records or streams frequently. Keep the appropriate backup access available rather than relying solely on an app.
Reliability Signals
Look for model-specific installation guidance, explicit weather ratings, and a clear fallback route instead of assuming a camera specification establishes lock durability. FamiLock S3 Max lists ANSI/BHMA Grade 1 and IP65; Lockin lists BHMA Grade 3 and IP53 for Veno Plus. Those ratings describe different attributes and do not guarantee a particular lifespan at your door. The eufy listing titled E331 deserves an additional identity check: its part-number field references E330/T8531, and eufy’s E330 guide documents 8 GB of built-in storage for T8531. Establish which model and kit you will receive before applying that guide’s storage details.
How to Compare Reviews
Filter any owner account by exact model, kit, and door arrangement. A report about Lockly Vision Elite storage does not establish the capacity of Lockly Vision PGD798ESN. Likewise, an E330 experience may not resolve the E331/E330 identity conflict in the listed eufy kit. For a myQ account, check whether it concerns the base lock or the extra-battery bundle and whether biometric access is available in the writer’s state. Give the most weight to descriptions that identify door thickness, storm-door clearance, Wi-Fi conditions, recording settings, and how often video was used; a battery-duration claim without those conditions is difficult to transfer to your home.
Common Mistakes
Do not mistake local storage for fully offline remote access, or assume that a wide-angle label guarantees a clear view of packages. Check the app and plan terms for the video functions you will use rather than treating every alert as included. Do not assume face or fingerprint entry works everywhere: myQ excludes those methods in Illinois and Texas. A matching handle in a product photo is not proof that a deadbolt-only kit includes one, and an extra battery belongs to the specified bundle, not automatically to the base model. Finally, resolve an unusual latch, mortise cutout, or obstructing storm door before choosing among otherwise appealing features.
Frequently Asked Questions
Can a smart lock with a camera replace my separate video doorbell?
It can serve as your visitor camera if its lens shows the area you care about and its live view, talk, alerts, and recording options meet your needs. Check the view from your actual door: a low package, deep recess, or storm door may make a separate camera useful.
Will I still be able to enter if Wi-Fi goes down?
Choose an entry method that does not depend on remote app access, such as the listed physical key or an appropriate on-lock credential. Confirm the exact model’s offline behavior separately from its low-battery behavior; the FamiLock S3 Max, for example, limits functions when it switches to AAA backup.
Does local video storage mean there is no subscription?
Not necessarily. Lockin Veno Plus advertises 8 GB of local video storage without a monthly fee for its named core features. Other models may separate free live viewing from paid history or detection: myQ requires a plan for video history and smart detection. Check the exact functions you want, not just the storage label.
Will Matter or voice-assistant compatibility show my lock’s camera feed?
Do not assume so. FamiLock S3 Max supports Matter for compatible smart-home functions, but eufy says its camera stream is not available through Matter; use the eufy app for full video features. Check each lock’s supported controls in the platform you intend to use.
Final Recommendation
Choose the eufy FamiLock S3 Max if your door fits and you want palm-vein entry, visitor video, and an indoor screen in one lock. Choose Lockin Veno Plus instead if fingerprint access and documented local video storage are higher priorities—and your wooden door meets its specific fit requirements.
