Unlock with a Wave — Palm Vein Security Meets a 2K Video Doorbell
The eufy FamiLock S3 Max reinvents your front door with palm vein recognition — infrared sensors read the unique vein pattern beneath your skin, a biometric that's extremely hard to copy and isn't affected by age or skin condition. Recognition takes under 0.1 seconds, and a 158.5° wide-angle lens with 360° adaptive detection reads hands of any size from any angle, even in bright direct sunlight.
It's also a full video doorbell: a built-in 2K HDR camera covers 180° of your doorstep with 16GB of built-in storage, while the 4-inch 1080p interior display gives you instant live view from inside. Dual motion sensors with AI loitering detection cut false alarms, and real-time video calls plus remote unlocking are handled from the app.
Power comes from a PowerDuo system — a 15,000mAh rechargeable battery backed by 4 AAA batteries — for up to 5 months per charge. ANSI/BHMA Grade 1 certification and IP65 weather resistance keep it secure outdoors, and it integrates with Apple Home, Alexa, Google Home, SmartThings, and Matter.
