The problem
Standard smart doorbells tell you that someone is at the door — not who — and bury the moment in a cloud subscription.
The solution
A Raspberry Pi facial-recognition system (OpenCV + scikit-learn) hitting 85% detection accuracy, paired with a React Native + Firebase app for real-time monitoring and user management — known faces are recognized, unknown visitors trigger an alert, and households manage their own face library.
