Raspberry Pi-Based IP Public Address, CCTV, and Access Control System for Educational Purposes

Abstract

This paper presents a cooperative project developed by two technical vocational schools. The project consists of the design and implementation of a prototype of an IP Public Address, closed circuit TV (CCTV) and access control system that uses the “Raspberry Pi” single-board computer as control system and non-electronic parts made with a 3D printer. The aim of the project is training students in maintenance of Voice over IP, audio and video. The project has been funded by the regional government Xunta de Galicia.
