Distributed Video Antifire Surveillance System Based on IoT Embedded Computing Nodes

摘要

This paper shows the design and (he implementation of a distributed video antifire surveillance system based on Raspberry Pi embedded computing board and RPi Camera, able to detect the smoke and trigger autonomously a fire alarm. These smart cameras will be placed in different areas under surveillance, connected together according to an IoT-scheme via wired (e.g. ethernet) or wireless (e.g. Wi-Fi) links, and accessible to several users via web browser. A centralized web interface node shows the video stream of each camera in real time, while a video processing algorithm is responsible for the smoke identification and for the decision making of a fire alarm. Furthermore, the system is able to auto record the video in case of fire alarm. Target applications are distributed smoke/fire alarms in smart cities or smart transport systems or smart factories.
