🏠 Design & Build Quality
Both the Famillock S3 and S3 Max feature premium metal construction, brushed finishes, and BHMA Grade 1 certification—placing them among the strongest consumer smart locks available. The S3 Max adds an interior display screen, letting you view live camera footage without using a phone, while the S3 keeps a slimmer, minimalist interior profile.
✋ Advanced Authentication & Access Control
Both models support palm vein recognition, offering 99.9% accuracy in under 0.6 seconds—more secure and hygienic than fingerprints. You also get:
• PIN codes (temporary, scheduled & permanent)
• Anti-peep scramble passcodes
• Auto-lock & intrusion lockout protection
The S3 Max’s internal screen adds an extra safety layer by allowing instant visitor verification from inside.
🔋 Battery Life & Backup Power
Eufy’s dual power system includes a massive 15,000mAh rechargeable battery plus AAA backup batteries. Even if the main battery runs out, the backup keeps your door working for weeks—great for peace of mind and busy households.
📷 Camera & Video Quality
Both smart locks feature:
• 2K HD resolution
• 150° head-to-toe view
• HDR for challenging lighting
Daytime footage is sharp and reliable, while night vision relies on IR (no spotlight). Audio is decent but not doorbell-level—acceptable for an all-in-one lock-camera system.
🌐 Smart Home Compatibility
Both models support:
✔ Matter
✔ Apple Home
✔ Google Home
✔ Alexa
✔ SmartThings
Camera streaming still runs through the Eufy app, but smart lock controls integrate seamlessly into your existing smart home ecosystem.
🏆 Final Verdict
👉 Choose the Famillock S3 Max if you want the most complete, family-friendly solution with an interior display—ideal for kids, seniors, or anyone who prefers screen-free monitoring.
