8 Best Palm Vein Smart Locks of 2025

The NUTOMO Palm Vein Smart Lock delivers a touch-free revolution for modern entryways, blending military-grade palm vein biometrics with seamless smart home integration. With 99.9999% accuracy, this lock outperforms traditional fingerprint systems, especially for users with worn or damp skin—making it a hygienic powerhouse ideal for families, Airbnb hosts, and multi-generational homes. The built-in WiFi eliminates hub dependency, enabling true remote access via the app, while local data storage ensures your biometrics never leave the device, addressing growing privacy concerns in a world of cloud breaches.

In real-world testing, the lock proves remarkably responsive, unlocking in under half a second with consistent palm recognition from any angle. It supports 360-degree palmaric scanning, so orientation isn’t a barrier—great for kids or elderly users who may not wave precisely. The 7800mAh USB-C rechargeable battery lasts about 8 months under moderate use, far surpassing most AA-powered competitors. However, in extreme cold (below 14°F), recognition speed dips slightly, and the keypad can be sluggish in heavy rain due to splash interference on the surface.

Compared to the Dhiedas and Wyze models, NUTOMO strikes a balance between security depth and smart features, though it lacks a built-in doorbell. It’s best suited for users prioritizing privacy-first biometrics and app control over video monitoring. While not the cheapest, it offers superior data security and broader compatibility than budget options, making it a smarter long-term investment than the Wyze Palm Lock despite a higher upfront cost.

The Dhiedas Palm Vein Smart Lock stands out with its blazing 0.1-second unlock speed, making it one of the fastest touchless entry systems in its class. Armed with 99.9% palm vein accuracy and a 10,000mAh battery, this lock promises a full year of standby power, ideal for those tired of constant charging cycles. Its 7-in-1 access system—including Apple Watch and Alexa—caters to tech-savvy households wanting flexibility, while the auto-lock and door sensor eliminate the nagging worry of leaving the front door ajar.

During daily use, the wave-to-unlock feature feels futuristic and reliable, even with gloves or wet hands, though it occasionally misreads if the hand waves too close or too fast. The built-in WiFi connects directly without a hub, allowing remote access and real-time alerts through the eSmartlock app—handy for monitoring deliveries or granting guest access. However, the camera-free design means you can’t verify who’s at the door remotely, and the app interface, while functional, lacks polish compared to eufy or Lockin.

When stacked against the NUTOMO B0F7QJ3GBX, Dhiedas wins on battery life and unlock speed, but falls short in data encryption transparency and build refinement. It’s a strong pick for users who value longevity and simplicity over advanced security architecture. For the price, it delivers more uptime and convenience than the Wyze model, though with less voice ecosystem depth.

The Lockin Veno Pro redefines front-door intelligence with its revolutionary 180°x180°x180° panoramic camera, slashing blind spots by 75% near door frames—a game-changer for package watchers and urban dwellers. This isn’t just a smart lock; it’s a privacy-centric security hub with on-device AI processing, 32GB local storage, and no cloud dependency, making it the gold standard for users wary of data leaks. The TÜV-certified palm vein recognition unlocks in 0.17 seconds with 99.9% accuracy, outpacing most rivals in both speed and reliability, even with messy or gloved hands.

In practice, the Veno Pro excels in low-light clarity and motion detection, thanks to IR night vision and AI-powered alerts that filter out false triggers like passing cars. The 2K camera captures head-to-toe footage, and two-way talk works seamlessly via the app. However, the bulkier design may not suit minimalist doors, and the initial setup requires careful alignment of the camera angle to avoid glare. While the 6 unlocking methods cover all bases, the fingerprint sensor can struggle in humid conditions.

Versus the eufy FamiLock S3, the Veno Pro offers superior camera coverage and local privacy, but lacks Matter compatibility, limiting smart home integration. It’s the top choice for privacy-focused homeowners who want maximum visibility and biometric precision without monthly fees. Though pricier than mid-tier models, it delivers better value than eufy S3 Max by avoiding cloud reliance while matching its video quality.

The Lockin Veno Smart Lock hits the sweet spot between cutting-edge biometrics and practical durability, offering 0.17-second palm vein unlocks with 99.9% accuracy—on par with high-end models but at a fraction of the cost. Its 7-month battery life is powered by efficient energy management, outlasting most competitors, and the IP65 rating ensures resilience in rain, snow, or desert heat. The no-drill DIY install takes under 15 minutes, making it perfect for renters or DIY newbies who want military-grade security without the hassle.

Real-world testing shows the palm recognition is nearly flawless, even with cold hands or minor cuts, and the 6 unlocking methods provide reliable backup options. The built-in doorbell and WiFi enable remote monitoring and voice control via Alexa, though the camera resolution is limited compared to Veno Pro or eufy. It lacks local storage, relying on app-based logs, which could be a privacy concern for some. Performance remains stable in most conditions, but the app occasionally lags during firmware updates.

Compared to the TCL D2 Pro, Lockin Veno offers better weather resistance and faster unlock speed, though both share similar battery life and doorbell integration. It’s a smarter pick than the Wyze Palm Lock for users wanting longer battery and stronger build quality, even at a slightly higher cost. For value-focused buyers who still demand speed and reliability, this lock delivers exceptional bang for the buck without sacrificing core security.

The eufy FamiLock S3 is a video-first powerhouse, merging a 2K HDR camera with f/1.6 lens and dual PIR + radar sensors to cut false alerts by 95%—a standout for homes plagued by motion noise from trees or pets. Its palm vein recognition is secure and steady, unlocking in 0.6 seconds with 99.9% accuracy, though slightly slower than Lockin’s 0.17s. The dual-battery system—15,000mAh main and AAA backup—delivers 4 months of active use, ensuring uptime even during blackouts, a critical edge for reliability-focused users.

In daily use, the HDR camera shines in low light, capturing clear facial details at night, and the 150° wide view covers most entryways, though not as fully as Lockin’s 180°. The Matter and Apple Home integration makes it a future-proof hub for smart home enthusiasts, supporting seamless automation with Alexa, Google, and SmartThings. However, camera streaming requires the eufy app, limiting Matter functionality, and the palm sensor needs precise hand positioning, occasionally requiring a second try.

Against the Lockin Veno Pro, the FamiLock S3 trades panoramic coverage for smarter ecosystem integration, making it better for users embedded in Apple or Google ecosystems. It’s less privacy-focused due to app reliance, but wins on automation depth and sensor intelligence. For those prioritizing smart home synergy over local storage, it offers stronger long-term value than TCL or Wyze, despite the premium price.

The Wyze Palm Lock is the budget king of biometric entry, delivering contactless palm vein security at a sub-$130 price—a rare feat in a market dominated by $200+ models. Its millimeter-wave radar intelligently wakes the lock only when a person is present, slashing power waste and extending battery life to 6 months, while a dual-battery system ensures you’re never stranded outside. The anti-peep keypad and 50 guest codes make it ideal for households with frequent visitors, and Alexa/Google voice control adds hands-free convenience.

In real-world use, the palm recognition is fast and reliable, though slightly less consistent than Lockin or NUTOMO in low light or with very small hands. The auto-lock gyroscope works impressively, detecting door closure angle and motion to prevent false locks. However, the IP53 rating means limited weather resistance, so it’s best for sheltered doors. The mechanical key override is a reassuring backup, but the plastic-heavy build feels less premium than metal-bodied rivals.

Compared to the TCL D2 Pro, Wyze offers better smart features and lower cost, but sacrifices battery longevity and weatherproofing. It’s the best entry point for smart lock newbies who want core biometrics without overspending. While it doesn’t match the security depth of NUTOMO or video quality of eufy, it outperforms similarly priced locks in AI smarts and ecosystem reach, making it a high-value starter lock.

The TCL D2 Pro carves its niche as the best mid-range palm vein lock with built-in doorbell, offering 8 months of battery life and IP55 weather resistance in a sleek, user-friendly package. Its AI-powered palm recognition is fast and hygienic, unlocking in under a second with strong consistency across skin types, while the integrated doorbell and voice control enable seamless Alexa or Google interactions—perfect for hands-free living. The TCL Home App allows remote access, real-time alerts, and detailed activity logs, giving homeowners full oversight without complexity.

During testing, the doorbell response was prompt, and the multi-user management worked smoothly for setting time-limited codes for cleaners or guests. The 10,000mAh USB-C battery charged quickly and held power impressively, though the lack of local storage means video clips rely on app access. The palm sensor occasionally hesitated in direct sunlight, requiring a re-scan, and the doorbell chime volume is fixed, which may be too quiet for large homes.

Versus the Wyze Palm Lock, the TCL D2 Pro offers longer battery, better weatherproofing, and more polished app experience, justifying its $40 premium. It doesn’t match the camera quality of eufy or privacy of Lockin, but for users wanting a balanced blend of doorbell, battery, and biometrics, it’s a smarter daily driver than entry-level models. It delivers better overall utility than Wyze without venturing into premium pricing.

The eufy FamiLock S3 Max earns its title as the best overall palm vein smart lock by combining top-tier 2K HDR camera quality, Matter-enabled smart home integration, and a game-changing rear video screen—a feature no other model offers. This screen lets kids and elderly users see visitors without a smartphone, making it the most accessible option for multi-generational homes. The palm vein unlock is secure and consistent, with 99.9% accuracy and local data storage, while the dual-power system ensures 5 months of total uptime, including emergency AAA backup.

In practice, the rear screen eliminates app dependency, a huge win for simplicity, and the HDR camera captures crisp, color-accurate footage day and night. The PIR + radar sensors minimize false alerts, and integration with Apple Home and Google Home is seamless. However, like the S3, camera streaming isn’t supported via Matter, requiring the eufy app for full features. The lock’s premium price reflects its capabilities, but the bulky front panel may not suit all door styles.

Compared to the Lockin Veno Pro, the S3 Max trades panoramic view and local storage for broader ecosystem support and family-friendly design. It’s the ideal choice for tech-forward households who want ultimate convenience and automation. While it costs more than the NUTOMO or Dhiedas, it delivers superior usability and integration, making it worth the investment for those seeking a complete, future-ready solution.
