Abstract
This research work presents a cost-effective facial recognition alert system using the ESP32 microcontroller to
enhance real-time security. The system integrates high-resolution cameras with Python’s facial recognition libraries to identify
individuals. When an unknown face is detected, it triggers an immediate alert via the ESP32, activating an alarm. This solution
is both scalable and affordable, making advanced security accessible to small businesses and residential areas. The system
improves overall security by automating surveillance, reducing the need for manual monitoring.
