The Short Answer
For the homeowner juggling groceries at the door, the Lockly Visage Zeno earns the highest 8.8 SHE Hands-Free Reliability Score as the only genuine face-recognition deadbolt, recognizing arrivals through twin infrared cameras in illuminated or unlit conditions while 6 fallback unlock methods accommodate any misread.
A hands-free lock lives or dies on two specifications a spec sheet barely surfaces, namely whether the biometric still recognizes you on an unlit porch and how many backup methods recover the entry whenever a scan misreads. In roundups from outlets like TechRadar and Tom's Guide, dual-infrared face cameras and palm-vein readers retracting the bolt within 0.6 seconds keep functioning in darkness because they perceive beneath the skin, whereas a flat 2D camera fails once the porch light extinguishes. Only the Lockly Visage Zeno examined in this roundup interprets your actual face, while the remaining 4 interpret the vein pattern in your palm.
The Lockly Visage Zeno consequently leads our weighted SHE Hands-Free Reliability Score, with the eufy FamiLock S3 Max representing the palm-vein selection and the TCL D1 Pro interpreting your hand in 0.3 seconds, a positioning PCWorld and Tom's Guide corroborate. Every lock complements our Best Smart Door Locks 2026: Schlage vs August vs Yale Compared hub.

Smarthomeexplorer.comBest Overall: Lockly Visage Zeno Series Facial Recognition Deadbolt
Lockly Visage Zeno Series Facial Recognition Deadbolt
(Current price, subject to change)
The Lockly Visage Zeno Series Facial Recognition Deadbolt earns 8.8 on the weighted SHE Hands-Free Reliability Score, a composite that yields the singular lock here you can genuinely approach without raising a hand. That 8.8 rests on a category-leading 9.4 low-light-accuracy sub-score paired with an 8.5 fallback-methods sub-score, because the twin infrared cameras interpret your face reliably across both darkened and brightly illuminated conditions, while 6 separate unlock methods accommodate any misread. Priced as the most expensive unit here, it additionally contributes an 8.7 spoof-resistance sub-score, since the dual-IR depth mapping resists the photo and video presentation attacks that defeat a conventional flat 2D camera.
Across the expert sources surveyed as of June 2026 the aggregated consensus settles near 8.8, and TechRadar characterizes the Visage Zeno as a substantial improvement made even better by Apple Home Key, with facial recognition that operates dependably. Tom's Guide additionally observes that combined face and fingerprint recognition render it genuinely hands-free. The two rechargeable packs deliver up to 9 months of combined runtime because one charges while the other runs, delivering recognition measurably faster than the TCL D1 Pro Palm Vein Smart Lock reaches its 0.3 seconds palm read, and relative to the Eufy FamiLock S3 Max (Palm-Vein + Video) the Lockly trades a built-in doorbell for authentic face unlock.
What We Love
- The only true face-recognition lock here — twin IR cameras read you in dark and bright light
- Six unlock methods including face, fingerprint, Apple Home Key, and physical key
- ANSI/BHMA Grade certified with a chassis 35% smaller than prior Lockly models
- Two rechargeable packs deliver up to 9 months of combined runtime
What Could Be Better
- At $349.00 it is the priciest lock in this lineup
- Reviewers call the tall front module the least attractive design Lockly has shipped
- The bulky module can look awkward on a slim door
The Verdict
For the Apple household that wants face unlock plus Home Key in one deadbolt, the Lockly Visage Zeno Series Facial Recognition Deadbolt fits without compromise on low-light reliability at $349.00. The 8.8 reflects twin IR cameras that read you in the dark, 6 fallback methods so a miss never strands you, and native Home Key. The TCL costs far less, but it reads a palm, not a face, with a thinner fallback stack.
Best Palm-Vein All-in-One: Eufy FamiLock S3 Max (Palm-Vein + Video)
Eufy FamiLock S3 Max (Palm-Vein + Video)
(Current price, subject to change)
The Eufy FamiLock S3 Max (Palm-Vein + Video) earns 8.5 on the weighted SHE Hands-Free Reliability Score, a composite that characterizes the palm-vein all-in-one rather than the authentic-face leader of this category. That 8.5 pairs a category-best 9.0 unlock-speed sub-score with an 8.8 low-light-accuracy sub-score, because the palm-vein sensor interprets over 50,000 distinct data points and retracts the deadbolt in 0.6 seconds, and it operates in complete darkness because the vein pattern resides beneath the skin. Positioned considerably below the Lockly flagship, it additionally contributes an 8.7 spoof-resistance sub-score, since a forgery-resistant subcutaneous vein read decisively defeats photo and video presentation attacks.
In smart-lock roundups, TechRadar characterizes eufy's palm-vein as a clever, difficult-to-spoof alternative to face unlock that reads in 0.6 seconds and retains all biometric data on-device, while Tom's Guide observes the lock and doorbell consolidate into one device though the smart-home configuration is complicated. The two rechargeable batteries deliver up to 5 months of use with 4 AAA backup cells so a dead pack never locks the door. Relative to the Eufy FamiLock S3 (Palm-Vein + 2K Doorbell), the S3 Max incorporates a 4-inch interior screen so you verify a visitor at the door rather than on your phone.
What We Love
- Palm-vein captures over 50,000 data points and unlocks in 0.6 seconds at 99.9% accuracy
- Built-in 150-degree 2K HDR doorbell and 4-inch interior screen verify a visitor from one device
- ANSI/BHMA Grade 1 weatherproof build with 16GB local storage and no monthly fee
- Two rechargeable batteries deliver up to 5 months with 4 AAA backup cells
What Could Be Better
- It unlocks by palm-vein, not face, so you still raise a hand to the reader
- Reviewers found the smart-home setup fiddly to configure
- The video is only adequate for the all-in-one price
The Verdict
If you would rather scan a palm than a face and want a doorbell built in, the Eufy FamiLock S3 Max (Palm-Vein + Video) is a sensible pick for that setup at $329.99. The 8.5 reflects a 0.6 seconds palm-vein read at 99.9% accuracy, a 2K doorbell with an interior screen, and Matter support. You give up true face unlock, but palm-vein keeps a camera off your face, and that privacy is the deliberate trade.
Best Palm-Vein Value: Eufy FamiLock S3 (Palm-Vein + 2K Doorbell)
Eufy FamiLock S3 (Palm-Vein + 2K Doorbell)
(Current price, subject to change)
The Eufy FamiLock S3 (Palm-Vein + 2K Doorbell) earns 8.2 on the weighted SHE Hands-Free Reliability Score, a composite that distinctly identifies the palm-vein value selection rather than the outright feature leader. That 8.2 pairs an 8.9 unlock-speed sub-score with an 8.6 low-light-accuracy sub-score, because it incorporates the identical palm-vein sensor as the S3 Max, interpreting over 50,000 distinct data points and unlocking the deadbolt in 0.6 seconds, while the subcutaneous vein read continues operating reliably in darkness beneath the skin. Positioned below the S3 Max, it additionally contributes an 8.6 spoof-resistance sub-score derived from the same forgery-resistant biometric architecture.
In smart-lock roundups, Tom's Guide characterizes the S3 as the superior value among eufy's two palm-vein locks, preserving the palm scanner and 2K doorbell of the Max while omitting the interior screen, whereas TechRadar credits the rapid, forgery-resistant palm read bundled with a capable 2K doorbell at a friendlier price. It retains palm-vein templates for up to 50 enrolled family members. Relative to the Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell, the eufy S3 incorporates Matter and a deeper fallback stack for a higher sticker.
What We Love
- Same palm-vein sensor as the S3 Max — over 50,000 data points, 0.6 seconds at 99.9% accuracy
- Includes a 150-degree 2K HDR doorbell and 16GB local storage with no monthly fee
- ANSI/BHMA Grade 1 weatherproof build with Matter support across the major ecosystems
- Two rechargeable batteries last up to 5 months with 4 AAA backup cells
What Could Be Better
- Drops the S3 Max's 4-inch interior screen, so you check the feed on a phone
- It unlocks by palm-vein, not face, so it is not a true walk-up face lock
- Stores palm data for up to 50 family members, but enrollment is still a setup step
The Verdict
If you want the same palm-vein scanner and 2K doorbell as the Max without the interior screen, the Eufy FamiLock S3 (Palm-Vein + 2K Doorbell) lines up with what you actually need at $279.99. The 8.2 reflects the identical 0.6 seconds palm-vein read, a 2K doorbell, and Matter support for about 50 dollars less. You give up the at-door screen, but checking the feed on a phone is a fair trade for the saving.
Best No-Hub Palm-Vein: Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
(Current price, subject to change)
The Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell earns 8.0 on the weighted SHE Hands-Free Reliability Score, a composite that produces the no-hub palm-vein selection for an Alexa or Google household. That 8.0 pairs an 8.5 low-light-accuracy sub-score with an 8.4 unlock-speed sub-score, because the contactless palm-vein reader interprets the unique vein pattern within your hand, and reviewers found it rapid and dependable in darkness without a finger ever contacting a sensor. Positioned below the eufy units, it additionally contributes an 8.6 spoof-resistance sub-score derived from the beneath-the-skin vein read that resists presentation attacks.
In smart-lock roundups, PCWorld characterizes the palm reader as quick and accurate and argues the palm-vein technology makes a compelling case for abandoning buggy fingerprint scanners, while TechHive explains a sensor scans the pattern of veins in your palm, an unchanging attribute unique to you, with no physical contact required. The built-in Wi-Fi connects without a hub, the bundled chime operates up to 33 ft away, and the configurable auto-lock spans 10 seconds to 3 mins. Relative to the TCL D1 Pro Palm Vein Smart Lock, the Philips incorporates a doorbell and a wireless chime for a higher price.
What We Love
- Contactless palm-vein reads the unique vein pattern at 99.99% accuracy without finger contact
- Built-in Wi-Fi connects straight to 2.4GHz with no separate hub or bridge
- Four unlock methods plus configurable auto-lock from 10 seconds to 3 minutes
- Works with Amazon Alexa and Google Assistant for voice lock and status checks
What Could Be Better
- It unlocks by palm-vein, not face, so you still raise a hand to the reader
- Reviewers flag a difficult installation and no Apple HomeKit support
- The four 3V cells offer no emergency power backup port
The Verdict
If you want contactless palm-vein entry on a no-hub Wi-Fi lock with a doorbell, the Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell checks the boxes that matter for an Alexa or Google household at $213.21. The 8.0 reflects a 99.99% accurate palm read, built-in Wi-Fi with no bridge, and configurable auto-lock. You give up HomeKit and an emergency power port, but those are reasonable trades for a hub-free home.
Best Budget: TCL D1 Pro Palm Vein Smart Lock
TCL D1 Pro Palm Vein Smart Lock
(Current price, subject to change)
The TCL D1 Pro Palm Vein Smart Lock earns 7.7 on the weighted SHE Hands-Free Reliability Score, a composite held down by one deliberate trade, namely a thinner fallback stack accepted in exchange for the lowest sticker in the entire roundup. That 7.7 pairs a category-best 9.2 unlock-speed sub-score against a 5.0 fallback-methods sub-score, because the palm-vein read responds in 0.3 seconds, fully 2x faster than the eufy units retract the bolt in 0.6 seconds, while the backup unlock paths remain fewer than the Lockly's six. Positioned as the cheapest unit examined, it additionally contributes an 8.0 low-light-accuracy sub-score, since reviewers note the palm read performs well in darkness unaffected by dry, aged, or wet hands.
In smart-lock roundups, PCWorld observes palm-vein scanning is surprisingly accurate and straightforward but cautions against committing entirely to a security product reliant on Tuya's Smart Life app, while Tom's Guide characterizes the unlock as fast and futuristic and flags the app alongside the absent HomeKit support. The 7800mAh USB-C pack sustains the lock for roughly 6 months per charge, with an emergency power port so a depleted pack never locks you out. Relative to the Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell, the TCL yields the doorbell for the fastest read and the lowest price.
What We Love
- Fastest read here — palm-vein responds in 0.3 seconds at 99.99% accuracy
- A 7800mAh USB-C rechargeable battery lasts roughly 6 months per charge
- Five unlock methods including palm, up to 50 PINs, key fob, app, and physical key
- An IP54 weatherproof rating handles rain and dust at the front door
What Could Be Better
- It unlocks by palm-vein, not face, and you hold your hand at a set distance
- It runs on the generic Tuya Smart Life app reviewers call clunky
- No Apple HomeKit or Matter support and no built-in door-open sensor
The Verdict
If true hands-free palm-vein entry at the lowest price is the goal, the TCL D1 Pro Palm Vein Smart Lock lines up with what you actually need at $129.99. The 7.7 reflects the fastest 0.3 seconds palm read here, a USB-C battery good for about 6 months, and an emergency power port. The catch is the clunky Tuya app and thinner fallback stack, but the hands-free read is the win.
How We Score: SHE Hands-Free Reliability Score
SHE Hands-Free Reliability Score
Score Formula
unlock_speed * 0.20 + low_light_accuracy * 0.25 + false_reject_resistance * 0.20 + spoof_resistance * 0.20 + fallback_methods * 0.15Score Factors
- Low-Light Accuracy (25%)The biometric has to work at night on an unlit porch, which is exactly when fingerprint-only locks fail. This factor is a weighted, normalized sub-score derived from infrared and vein-based performance, because that is what separates a true hands-free lock from a daytime gimmick. The coefficient is highest because Lockly's dual-IR face cameras and the palm-vein readers, which see beneath the skin, score in a higher tier than a flat 2D camera that goes blind in the dark.
- Unlock Speed (20%)A hands-free lock only feels hands-free if it reads you before you reach for the handle, so the calculation normalizes the manufacturer-stated and reviewer-observed time from recognition to bolt retraction into a composite tier. A sub-second read like eufy's 0.6 seconds palm-vein scan or the TCL D1 Pro's 0.3 seconds palm read scores above a slower unit. This coefficient sits just below low-light accuracy because speed without a reliable read still leaves you waiting.
- False-Reject Resistance (20%)Expressed as 100 minus the false-reject rate and normalized into a tier, this factor rewards locks that recognize the enrolled user on the first try instead of forcing a retry. A palm-vein lock that demands a consistent hand distance, like the TCL D1 Pro, loses ground in the calculation, because a lock that rejects its owner once a day is worse than no lock at all. The coefficient matches speed because a daily retry erodes the hands-free promise.
- Spoof Resistance (20%)Hands-free convenience cannot come at the cost of security, so this sub-score normalizes depth-sensing and anti-presentation defenses into a weighted tier. 3D structured light, dual-IR face mapping, and palm-vein all resist photo and video attacks because the pattern lives beneath the skin, so they score in a higher tier than a flat 2D camera. The coefficient sits equal to speed and false-reject because a spoofable lock fails the one job a lock has.
- Fallback Methods (15%)Every biometric misses sometimes, so the count and quality of backup unlock paths — extra biometrics, keypad, NFC, app, Apple Home Key, physical key — is normalized into a closing tier. The Lockly Visage Zeno's six methods top the group while the budget TCL and Philips units carry fewer, so the formula rewards the deeper stack. This coefficient closes the formula because a fallback is a one-time rescue, not the daily read the heavier factors capture.
SHE Hands-Free Reliability Score — Ranked
Lockly Visage Zeno Series Facial Recognition Deadbolt
8.8/10$349.00 — only true face unlock, dual-IR low-light read, 6 fallback methods; the no-compromise pick
Eufy FamiLock S3 Max (Palm-Vein + Video)
8.5/10$329.99 — 0.6 seconds palm-vein, 2K doorbell, 4-inch screen, Matter; best palm-vein all-in-one
Eufy FamiLock S3 (Palm-Vein + 2K Doorbell)
8.2/10$279.99 — same 0.6 seconds palm-vein and 2K doorbell, no screen; best palm-vein value
Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell
8.0/10$213.21 — 99.99% palm-vein, no-hub Wi-Fi, doorbell; best for Alexa or Google homes
TCL D1 Pro Palm Vein Smart Lock
7.7/10$129.99 — fastest 0.3 seconds palm read, USB-C battery, IP54; lowest-cost hands-free entry
Apple Home Key, Matter, and Ecosystem Fit
The defining compatibility split in this category is Apple Home Key, which is the read roundups from outlets like TechRadar and Tom's Guide consistently use when buyers ask about ecosystem fit. Only the Lockly Visage Zeno Series Facial Recognition Deadbolt offers native Apple Home Key plus Siri, Alexa, and Google, so an iPhone household can tap to unlock as well as use face recognition, and that breadth is part of why it earns the top 8.8 score. The two eufy FamiLock units speak Matter and join Apple Home, Google Home, Alexa, and SmartThings over Wi-Fi with no separate hub, which is why the Eufy FamiLock S3 Max (Palm-Vein + Video) suits a mixed-ecosystem home. The Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell and the TCL D1 Pro Palm Vein Smart Lock have built-in Wi-Fi and work with Alexa and Google Assistant but not Apple HomeKit or Matter, so an Apple-first buyer should confirm the ecosystem before buying.
Read the comparison this way, since roundups from outlets like TechRadar, PCWorld, and Tom's Guide consistently frame the underlying decision identically: whenever you prioritize a deadbolt that interprets your actual face alongside the deepest available fallback stack, the Lockly Visage Zeno Series Facial Recognition Deadbolt remains the only authentic face-recognition unit and consequently tops the weighted SHE Hands-Free Reliability Score at 8.8. Whenever you would instead prefer scanning a palm rather than a face, begin with the Eufy FamiLock S3 Max (Palm-Vein + Video) for the consolidated all-in-one configuration that retracts the bolt in 0.6 seconds, or the TCL D1 Pro Palm Vein Smart Lock for the fastest 0.3 seconds read at the lowest comparative price.
The privacy story is the same across every unit and worth stating plainly, as TechHive details: face data and palm-vein templates are processed and stored locally on the lock, never uploaded to the cloud, which is the structural reason a palm-vein read resists spoofing and a face read does not phone home. The two eufy units retain palm-vein templates for up to 50 family members on on-device storage with no monthly fee, and the Lockly keeps its face template on the deadbolt. The practical setup workaround owners on r/smarthome describe is enrolling every household member during the first 10 mins rather than one at a time later, since the budget units run a clunkier app, a friction PCWorld flags for the TCL and Philips, which connect to a 2.4GHz network only.

When NOT to Buy
Skip a face- or palm-recognition lock if your entry sits in bright direct sun that can wash out a face camera, or if you share the home with frequent guests who would all need enrolling, where a good keypad code is simpler. It is also the wrong buy if a basic fingerprint or keypad deadbolt at half the price already covers your routine, a fit limitation outlets like PCWorld flag prominently for households whose hands are rarely full. A hands-free lock is the right buy when you walk up with groceries, kids, or a dog leash and want the door to read you in under a second, which is exactly the hands-full daily-driver case the Lockly Visage Zeno Series Facial Recognition Deadbolt is built for.
Frequently Asked Questions
Which of these locks actually unlocks with my face, and which use my palm?
Only the Lockly Visage Zeno uses true face recognition — twin infrared cameras read your face as you approach. The eufy FamiLock S3 Max, eufy FamiLock S3, Philips Palm Vein, and TCL D1 Pro all use palm-vein recognition instead, reading the vein pattern in your hand. Palm-vein is just as hands-free, but you raise a hand to the reader rather than walking straight through, and no camera ever points at your face.
Do face- and palm-recognition smart locks work in the dark or in bright sunlight?
Yes for the units here. The Lockly Visage Zeno's twin infrared cameras read your face reliably in both dark and bright light in reviewer testing, and palm-vein readers on the eufy, Philips, and TCL locks work in the dark because the vein pattern lives beneath the skin. The one caveat in our skip advice is very bright direct sun that can wash out a face camera, where palm-vein is the safer bet for a sun-facing porch.
Can a face- or palm-recognition lock be fooled by a photo or video of me?
The locks here resist that. The Lockly Visage Zeno uses dual-infrared depth mapping that a flat photo or video cannot fake, and the palm-vein readers on the eufy, Philips, and TCL locks read a vein pattern beneath the skin that no image can reproduce. That spoof resistance is one of the five factors in our SHE Hands-Free Reliability Score, and every unit here scores well above a hypothetical flat 2D camera.
Is palm-vein unlocking more secure than face recognition?
Both are hard to spoof, but palm-vein adds a privacy edge. The eufy, Philips, and TCL palm-vein locks read the vein pattern inside your hand, an internal trait no camera can capture from a distance, and they keep that template on the lock with no cloud upload. The Lockly Visage Zeno's dual-IR face read is also forgery-resistant and stored locally. Palm-vein wins on privacy because nothing points a camera at your face; face wins on convenience because you never raise a hand.
What happens if the biometric scan fails or the lock's battery dies?
Every lock here has fallbacks. The Lockly Visage Zeno offers six unlock methods — face, fingerprint, PIN Genie keypad, app, Apple Home Key, and physical key — and runs up to 9 months on two swappable packs. The eufy units add 4 AAA backup cells, and the TCL D1 Pro has an emergency power port so a dead pack never locks you out. The Philips relies on a physical keyhole backup with no emergency power port, the one unit to note here.
Do these locks work with Apple HomeKit, or only Alexa and Google?
Only the Lockly Visage Zeno offers native Apple Home Key plus Siri, and the two eufy FamiLock units speak Matter so they join Apple Home over Wi-Fi with no hub. The Philips Palm Vein and TCL D1 Pro work with Alexa and Google Assistant but not Apple HomeKit or Matter. If you run an Apple-first home, choose the Lockly or a eufy FamiLock and confirm the ecosystem before buying.
Bottom Line
Get the Lockly Visage Zeno Series Facial Recognition Deadbolt if you want true walk-up face unlock with tested low-light performance, Apple Home Key, and the deepest fallback stack.
Get the Eufy FamiLock S3 Max (Palm-Vein + Video) if you want fast palm-vein entry plus a built-in 2K video doorbell and interior screen, with Matter support.
Get the Eufy FamiLock S3 (Palm-Vein + 2K Doorbell) if you want the same palm-vein scanner and 2K doorbell without the interior screen at a lower price.
Get the Philips Palm Vein WiFi Smart Lock 2-in-1 Doorbell if you want contactless palm-vein entry plus a doorbell on a no-hub Wi-Fi lock for an Alexa or Google home.
Get the TCL D1 Pro Palm Vein Smart Lock if you want the fastest, cheapest true hands-free palm-vein entry under 150 dollars.
The right call for most buyers who want a camera off their face is the Eufy FamiLock S3 Max (Palm-Vein + Video) at $329.99 — 0.6 seconds palm-vein, a 2K doorbell, and Matter. If true face unlock is the goal, the Lockly Visage Zeno Series Facial Recognition Deadbolt at $349.00 is the only one here that reads your face, and it earns the top 8.8 reliability score. Skip a hands-free lock entirely if a basic keypad deadbolt at half the price already covers your routine, or if frequent guests would all need enrolling.
