Architecture Engineering and Science

With the advancement of IoT, artificial intelligence, and big data, intelligent building security systems are shifting from passive defense to proactive perception and intelligent decision-making. Based on the intelligent building concept, this paper proposes a “perception–transmission–analysis–execution” architecture, analyzes key technologies including multi-sensor fusion, AI-based video analytics, big data with cloud computing, edge computing, and network security, and discusses system integration, interoperability, and sustainable maintenance strategies, providing references for enhancing the intelligence and integration of building security management.
