Eufy Familock S3 Max Video Smart Lock

eufy Security FamiLock S3 Max – 2K Video Smart Lock with Palm Vein Recognition

The eufy Security FamiLock S3 Max is a revolutionary smart lock that combines advanced biometric security, built-in video monitoring, and seamless smart home integration. Featuring palm vein recognition technology, a 2K camera, and a built-in digital screen, this lock provides unmatched security and convenience for families.

Palm Vein Recognition – A New Standard in Biometric Security

Unlike fingerprint scanners, palm vein recognition ensures highly secure, contactless unlocking. The sub-palm vein technology detects blood flow through veins, making it more accurate and reliable than traditional fingerprint sensors. This technology works seamlessly for children with faint fingerprints, seniors with worn skin, and even wet or sweaty hands.

2K Video Camera with Live View & Smart Alerts

The built-in 2K camera provides a clear, head-to-toe view of visitors and packages on your porch. With a 150° vertical and 180° diagonal field of view, you can monitor everything at your doorstep. The live feed is displayed on the lock’s built-in screen, allowing you to see who’s at the door without needing a smartphone.

Multiple Unlocking Methods for Maximum Convenience

The FamiLock S3 Max supports five different unlocking methods, including:

• Palm Vein Recognition – Simply wave your hand over the sensor for a secure, touch-free entry.

• Touchscreen Keycode Entry – Set personalized PIN codes for family members and guests.

• Eufy Security App – Unlock remotely from anywhere.

• Physical Key Backup – A hidden keyway button conceals the key slot for emergency access.

• Matter Compatibility & Smart Home Integration – Works with Apple Home, Amazon Alexa, and Google Assistant for seamless automation.

Built-In Digital Peephole for Instant Visibility

Unlike other smart locks that require an app, the FamiLock S3 Max includes a rear screen that shows a live feed of visitors. The screen activates within one second of motion detection, allowing anyone at home—including children or babysitters—to instantly see who’s at the door without needing a phone.

Reliable, Long-Lasting Battery Life

Powered by a 15,000mAh removable rechargeable lithium battery, the lock provides six to twelve months of battery life on a single charge. To prevent downtime, the lock can also run on four AAA batteries as a backup, ensuring it stays online even while charging.
