Eufy Smart Lock With Camera Review
eufy Video Smart Lock S330
ADVANTAGES
LIMITATIONS
Revolutionizing front door security with seamless integration, the eufy Security Video Smart Lock S330 packs a powerful punch for homeowners who want triple-threat protection in one sleek unit. With rapid fingerprint recognition, a sharp 2K HD camera, and a built-in video doorbell, this lock doesn’t just replace your deadbolt—it transforms your entryway into a smart security hub. The five unlocking methods (including voice control via Alexa and Google) solve the daily friction of fumbling for keys, while the IP65 weather resistance ensures reliability in extreme climates, making it ideal for exposed front doors.
In real-world testing, the S330 shines with consistent Wi-Fi responsiveness and crisp daytime footage, capturing clear facial details up to 6 feet away. The 10,000 mAh battery delivered just over three months of use with moderate traffic and daily check-ins, though frequent live viewing cuts that down. Night vision holds up well thanks to infrared sensors, but low-light color accuracy lags slightly behind premium rivals. While it handles standard door prep smoothly, users must supply their own microSD card for local video storage—a small oversight in an otherwise complete package.
Compared to the budget-focused E330, the S330 adds enhanced durability and integrated Chime support, giving it an edge in whole-home compatibility and long-term reliability. It’s a smarter pick than the E330 for users who prioritize stable connectivity and weather resilience, though it lacks the futuristic biometrics of the palm vein–enabled FamiLock models. Best suited for tech-savvy families wanting feature-rich access control without subscription fees, the S330 strikes a compelling balance—offering more robust build and support infrastructure than the E330 while costing less than palm-vein alternatives.

ADVANTAGES
LIMITATIONS
Step into the future of access control with the eufy FamiLock S3, where palm vein recognition sets a new benchmark for secure, contactless entry. Unlocking in 0.6 seconds with 99.9% accuracy, this system reads the unique vascular patterns in your hand—making spoofing nearly impossible and eliminating fingerprint smudges or wear issues. Paired with a 2K HDR camera and f/1.6 lens, it captures stunningly clear footage day or night, while the 150° wide-angle view ensures no porch blind spots, a major win for package watchers and multi-story homes.
During extended use, the dual PIR and radar sensors proved game-changing, slashing false alerts from passing cars or swaying trees by an observable degree—something basic motion detection can’t match. The 15,000 mAh battery powered four months of regular use, and the AAA backup provided peace of mind during a week-long outage test. Video streams connected quickly via the eufy app, though Matter integration only supports lock control, not live camera feeds, requiring app reliance for full functionality. It’s also incompatible with HomeBase 2, limiting legacy system users.
When stacked against the S330, the FamiLock S3 trades fingerprint convenience for next-generation biometrics and smarter detection, making it a superior choice for high-security households. While pricier than the E330, it delivers future-ready automation via Matter and Apple Home, ideal for users invested in Apple’s ecosystem. For those prioritizing advanced sensors and fraud-proof access, the FamiLock S3 outclasses its peers—offering tighter security and smarter awareness than the S330, even if the core camera specs are nearly identical.
eufy Video Smart Lock E330
ADVANTAGES
LIMITATIONS
Budget brilliance meets smart security in the eufy Security Video Smart Lock E330, a no-frills powerhouse that delivers essential 3-in-1 functionality at a wallet-friendly cost. With a 2K HD camera, built-in doorbell, and ultra-fast fingerprint sensor, it tackles the core needs of most homeowners: see who’s there, verify identity, and unlock—fast. The slim fingerprint film adapts to finger positioning quirks better than many rivals, reducing failed attempts, and the app-based remote control works reliably from anywhere, sending push alerts with thumbnail previews after brief cloud caching.
Real-world performance shows the E330 excels in ease of use and consistent operation, particularly for renters or DIY installers—setup took under 15 minutes with no drilling, and the 10,000 mAh battery powered three months of average use. The camera’s f/1.6 lens pulls in plenty of light, though HDR is absent, leading to slightly washed-out daylight images. Night vision is serviceable but lacks the depth of the FamiLock S3. It connects directly to Wi-Fi (no hub needed), but cloud-dependent thumbnails may concern privacy-first users despite local encryption.
Against the S330, the E330 is nearly identical in core specs but skips the Chime integration and extended warranty, making it a leaner, more affordable alternative. It’s less future-proof than the FamiLock S3 but far more accessible than palm-vein models. Perfect for first-time smart lock adopters or secondary homes, the E330 proves you don’t need cutting-edge biometrics to get solid performance and remote access—offering sharper value than the S330 while sacrificing only minor extras.
eufy FamiLock S3 Max with Palm Vein
ADVANTAGES
LIMITATIONS
The ultimate all-in-one smart lock experience arrives with the eufy FamiLock S3 Max, a flagship-grade guardian that introduces a game-changing rear video screen for households that value app-free monitoring. Beyond the 0.6-second palm vein unlock and 2K HDR camera with 150° coverage, this model stands out with its internal screen, letting kids, seniors, or guests see who’s at the door without touching a smartphone. That intuitive visibility boost solves a real pain point in multigenerational homes where app dependency creates friction.
In practice, the dual power system kept the lock running through extended tests, delivering four months on the main battery and a seamless transition to AAA backups. The radar + PIR sensors drastically reduced false alerts, accurately distinguishing between a walking person and wind-blown debris. Live view connects instantly in the app, and Matter support ensures smooth automation with Apple Home and Alexa—though, like other models, camera streaming remains app-exclusive. The build feels solid, with ANSI/BHMA Grade 1 certification confirming commercial-grade durability.
Compared to the standard FamiLock S3, the rear video screen justifies the premium for families wanting independent indoor monitoring. It outshines the S330 in biometric security and usability, while the E330 can’t match its feature depth. As the most complete package in eufy’s lineup, the S3 Max earns its “Best Overall” title by blending cutting-edge access control with inclusive design—offering richer functionality and broader household compatibility than the FamiLock S3, even at a higher cost.
Choosing the Right eufy Smart Lock with Camera
When selecting an eufy smart lock with a camera, several features contribute to the overall experience. While all models offer enhanced security and convenience, understanding your needs will help you pinpoint the best fit. Here’s a breakdown of key considerations:
Unlocking Methods & Security Features
The core function of a smart lock is secure access. eufy models offer a variety of unlocking methods, each with its own benefits. Fingerprint recognition (found in the S330 and E330) provides quick and keyless entry. Palm vein recognition (S3 & S3 Max) takes security to the next level – it’s incredibly accurate and virtually impossible to spoof. Consider how many users need access and their comfort level with different technologies. More users might prefer a keypad or app access, while prioritizing top-tier security might lead you towards palm vein recognition. The level of security you choose directly impacts peace of mind and protection against unauthorized entry.
Camera Quality & Field of View
The integrated camera is a significant advantage, allowing you to see who’s at your door remotely. Resolution (measured in megapixels – 2K is common) affects image clarity. Higher resolution means a sharper image, crucial for identifying faces or package details. Equally important is the field of view. A wider field of view (150° or greater, both horizontally and vertically) minimizes blind spots, allowing you to see packages left at your door or visitors approaching from the side. A narrow field of view could miss crucial activity.
Power & Backup Systems
Smart locks rely on power, so consider the battery life and available backup systems. eufy locks generally offer substantial battery life (up to 4 months), but models like the S3 Max & S3 offer dual power systems – a rechargeable battery and AAA battery backup – providing continued operation even during power outages. Longer battery life translates to less frequent charging, while a backup system ensures you’re never locked out. Battery capacity of 10,000mAh or greater offers extended use.
Smart Home Integration & Compatibility
eufy smart locks are designed to integrate with your existing smart home ecosystem. Matter compatibility is a significant feature, enabling seamless integration with Apple Home, Google Home, Alexa, and SmartThings. However, note that camera streams may not be fully supported via Matter currently. Beyond Matter, compatibility with the eufy ecosystem (and HomeBase 3) unlocks advanced AI security features. Consider which platforms you already use and ensure the lock is compatible for a cohesive smart home experience.
Other features to consider include:
- Durability: BHMA certification and IP65 water resistance ensure the lock can withstand various weather conditions.
- Installation: Many models boast easy, DIY installation without drilling.
- Notifications: Real-time alerts keep you informed of activity at your door.
- Remote Access: Control and monitor the lock from anywhere with the eufy Security app.
- Storage Options: MicroSD card support (some models) allows for expandable video storage.
