This article presents the architecture of an autonomous security system designed to protect automated monitoring equipment for water resources located near open water bodies. The basis of the proposed solution is a sensor platform based on the use of a single-mode optical fiber as a sensor, capable of registering the presence of people in the protected area. The system is implemented on a Raspberry Pi single-board microcomputer. The key element of the architecture is a multi-level structure of interaction between components: the optical fiber registers external influences, changes in the optical signal are recorded by a photomatrix, then the information is analysed using built-in algorithms, and if an anomaly is detected, video surveillance and alarm notification modules are activated. The architecture is complemented by an IoT module that provides data transmission and centralized control in a distributed system. The developed software is an integral part of the system and provides real-time control of all components of the complex. The proposed system operates in a completely autonomous mode thanks to the use of a solar panel as the main source of power supply, which eliminates the need to connect to a centralized power grid and the constant presence of maintenance personnel.
