The eufy FamiLock S3 Max is a front-door smart lock that combines advanced security with convenient video monitoring. Its standout feature is the palm vein recognition technology, which offers highly accurate and fast keyless entry based on unique vein patterns—this adds a strong layer of security beyond traditional fingerprint or keypad methods. The integrated 2K HDR camera provides clear video with a wide 150° field of view and effective night vision, allowing you to see visitors head-to-toe and monitor packages without blind spots. Two-way audio lets you communicate easily through the video doorbell function.
A practical plus is the rear lock video screen, which lets users check door status without needing a smartphone app—a helpful feature for older adults or children. Power-wise, it uses a rechargeable battery lasting about four months, supported by backup AAA batteries for emergencies, so it keeps working even during outages. Connectivity is via Wi-Fi with compatibility across major smart home platforms like Apple HomeKit (via Matter), Alexa, Google Home, and SmartThings, though full camera streaming requires the eufy app for now.
The lock is a robust, ANSI/BHMA Grade 1 deadbolt made from aluminum, emphasizing durability. Some potential drawbacks include reliance on the eufy app for advanced camera features and the current limitation of not supporting camera streams through Matter. Also, while the biometric palm scan is secure, it might be unfamiliar to some users initially. The device’s size and weight are notable but manageable for most standard doors. This product is well suited for users who want cutting-edge biometric security combined with high-quality video monitoring and easy smart home integration, especially families prioritizing safety and convenience who appreciate quick, app-free access via the rear screen.
The eufy Security Video Smart Lock E330 is a versatile front-door lock that combines three essential features: a fingerprint recognition smart lock, a 2K HD camera, and a video doorbell. This integration allows for comprehensive security and convenience. The camera provides clear visibility with a high resolution and a wide field of view, including night vision capability, ensuring you can monitor your door day and night. Connectivity is seamless with built-in Wi-Fi, allowing remote control via the eufy Security app, Alexa, or Google Voice Assistant. The lock offers multiple ways to unlock, including fingerprint recognition, keypad, and traditional keys, catering to different preferences and situations.
One standout feature is the large 10,000 mAh rechargeable battery, which powers the entire unit and eliminates the need for frequent battery replacements. Installation is simple and quick, compatible with most standard deadbolt spacings, and requires no drilling. The product is supported by excellent customer service and an 18-month protection plan. However, it may require cloud storage for thumbnail previews in notifications, which could be a consideration for those wary of cloud services.
The combination lock type may take some getting used to for users accustomed to traditional locks. With a solid build of aluminum and a user-friendly design, this lock is best suited for individuals looking for a high-tech security solution for their front door, integrating smart home features and robust security measures.
The Lockly Vision Zeno smart lock is a strong choice for anyone wanting a secure front-door lock combined with a high-quality camera and smart features. Its 2K resolution camera with night vision and a wide field of view makes it easy to see visitors clearly, even after dark. The built-in video doorbell and two-way audio allow you to speak with people at your door from anywhere, adding a helpful layer of security. Connectivity is solid thanks to Wi-Fi support, enabling remote control through the Lockly app, voice assistants like Alexa and Google, and integration with Apple Home Key for smooth Apple device users.
Power comes from two rechargeable lithium batteries that can last about six months, which means less hassle than frequent battery changes. The lock itself is a deadbolt made of durable metal, designed to resist weather conditions, making it well-suited for outdoor use. Multiple unlocking methods—including fingerprint scanning, keypad with PIN Genie technology, app control, voice commands, and physical keys—offer flexibility and convenience. Installation is straightforward without needing extra wiring or drilling, suitable for most standard US doors.
On the downside, the smart lock's app and system might feel a bit complex for users new to smart home tech, and the price may be higher compared to basic locks without cameras. Additionally, while the rechargeable batteries are convenient, you still need to remember to recharge them periodically. If you want a reliable, all-in-one security solution that combines modern smart features with robust physical security, the Lockly Vision Zeno delivers a balanced mix of convenience, safety, and tech integration.
