Abstract

This paper presents a unique low-cost prototype for an intelligent security system designed to mitigate theft risks in small businesses and homes across Latin America—an innovation that uniquely integrates all key functionalities in a single, cohesive product. The system combines an ESP32CAM for real-time image capture, WiFi connectivity, and direct control of two SG90 servos for dual-axis movement, with a PIC16F887A microcontroller that activates a KY-008 laser module upon receiving a digital high signal. The ESP32CAM establishes a local server to transmit live video to a laptop, where a cascade-based detection algorithm identifies potential threats. Upon detection, the system computes the necessary angular adjustments, directing the servos to orient the laser assembly precisely, while the PIC16F887A triggers the laser module. All components are housed in a modular 3D-printed structure fabricated from black PLA, ensuring ease of assembly, maintenance, and scalability. Experimental evaluations confirm the system’s rapid response and reliability, underscoring its potential as a cost-effective security solution in resource-limited environments. No other product on the market currently offers this level of integrated functionality, making this prototype a pioneering advancement in intelligent security systems.
