eufy FamiLock S3: Palm Vein Smart Lock with 2K Camera & Doorbell

Elevate your doorstep security with the eufy FamiLock S3

Meet a smart lock designed for modern households that value convenience, privacy, and reliable protection. The FamiLock S3 combines palm vein recognition with a high‑resolution camera and doorbell features to create an all‑in‑one entry solution. The palm vein system reads unique vein patterns in just fractions of a second, and your biometric data is stored locally on the device, helping keep sensitive information off the cloud.

In addition to keyless entry, the lock integrates a 2K HD camera with an f/1.6 lens and HDR to deliver clear footage even when lighting is challenging. The wide field of view minimizes blind spots, so you can observe visitors and packages from an expansive angle, reducing uncertainty when you’re not at the door.

What makes it dependable

• Palm Vein Unlocking: Quick recognition (about 0.6 seconds) with forgery‑resistant authentication and on‑device data protection.
• 2K Camera with Wide Coverage: HDR, low-light clarity, and up to 150° vertical, 150° horizontal, and 180° diagonal views.
• Power Assurance: A 15,000 mAh rechargeable battery runs for several months, with 4 AAA backups for continued operation during outages.
• Smart Detection: Dual PIR and radar sensors reduce false alarms while delivering timely access alerts.
