Dispositivo de seguridad basado en reconocimiento facial y lector de tarjetas RFID

Abstract

This work presents the development of an intelligent access control system based on the Raspberry Pi 4, aimed at effectively enhancing the security and management of restricted areas through automatic identification technologies. The proposed solution integrates facial recognition, RFID card verification, physical access control via a relay, and real- time notifications through the Telegram application, resulting in a comprehensive and easily monitored system. For its implementation, a facial database consisting of 300 images of the authorized user was created, enabling model training and improved recognition accuracy. Access validation is performed through a two-level security process, with facial recognition serving as the first authentication layer and RFID card verification as the second. Each access attempt, whether authorized or unsuccessful, automatically triggers a notification to the system administrator, allowing immediate and remote monitoring. Experimental results demonstrated efficient performance under various access scenarios, significantly reducing the risk of unauthorized entry and ensuring reliable control, thus confirming that the integration of these technologies provides a secure, cost-effective, and practical solution for environments requiring continuous surveillance and enhanced security.
