## Understanding Face ID Technology Face ID has revolutionized how we unlock our smartphones, and now this same technology is available for your home's entry points. But how does it work, and is it really secure? ### How 3D Facial Recognition Works Unlike simple camera-based facial recognition, true Face ID uses 3D mapping technology: 1. **Infrared projection** - Thousands of invisible dots are projected onto your face 2. **Depth mapping** - A camera captures how these dots create a 3D map of your facial features 3. **Neural processing** - Advanced algorithms compare this map against stored profiles 4. **Authentication** - If matched, access is granted in under 0.5 seconds ### Why It's Secure 3D facial recognition is extremely difficult to fool: - **Can't be tricked by photos** - 2D images don't have depth information - **Adapts to changes** - Glasses, beards, aging—the system learns over time - **Works in darkness** - Infrared doesn't need visible light - **Encrypted storage** - Facial data is stored locally and encrypted ### The Convenience Factor The real magic of Face ID for doors is the hands-free experience. Imagine walking up to your door with groceries and having it unlock automatically as you approach. No fumbling for keys, no typing in codes—just seamless entry. ### Avyra's Implementation Our smart doors and Elite Pro lock use the latest 3D facial recognition technology, the same grade used in high-security applications. Combined with our other unlock methods, you get ultimate flexibility and security.
