With the increasing complexity and diversification of campus safety issues, traditional security management methods are no longer sufficient to meet the security needs of modern campuses. Frequent incidents such as stampedes, knife attacks, and hostage situations not only pose serious threats to the lives and property of teachers and students but also severely disrupt the normal teaching order of schools. To effectively improve campus safety management, we propose a campus visual command and safety dispatch system solution based on advanced information technology. This system aims to provide comprehensive and intelligent protection for campus safety through real-time monitoring, intelligent early warning, and rapid response.

The campus visual intelligent safety dispatch system uses streaming media exchange transmission, audio and video encoding and decoding, mobile communication networks, and cloud computing services as core technologies. Through portable smart terminals, it enables real-time audio and video transmission and sharing, cross-regional group intercom, linked alarms, image capture, GPS/BeiDou location query, trajectory tracking, electronic fence attendance, task dispatch, command issuance, and dynamic group dispatch. This system aims to achieve comprehensive intelligent command and dispatch from front-end equipment to the dispatch platform, thereby improving campus safety.

The emergency response system topology diagram for schools in the area includes key nodes such as the school alarm dispatch platform, the public security bureau command center, the dispatcher's command and dispatch console, and the security post at the school gate where police officers respond to calls. Through devices such as one-button alarm devices, law enforcement recorders, cameras, and loudspeakers, rapid coordination between schools and the public security department is achieved.

System Architecture

The campus visual command and safety dispatch system mainly consists of three parts: school-side equipment, platform layer, and terminals for relevant responsible persons.

• School-side equipment‌：These include one-button alarm devices, cameras, loudspeakers, and AI edge servers. These devices are deployed in key areas of the campus for real-time monitoring and intelligent early warning.
• Platform layer‌：The city-level public security internal security command center platform was deployed. This platform supports functions such as multi-terminal video fusion, AI analysis, and alarm distribution, and is the core processing center of the system.
• Relevant responsible persons' terminals‌：This includes terminal equipment for officials from public security bureaus, education bureaus, and schools, used to receive alarm information and conduct command and dispatch.

Application Functions

The district's school emergency response system includes a tiered response mechanism, a psychological crisis intervention module, video surveillance, AI analysis, communication linkage, broadcast linkage, online roll call, and customized contingency plans. The system automatically issues alerts when abnormal behavior is detected by AI cameras, or when security personnel manually trigger an alarm. It can then automatically push video streams to the public security platform and trigger the corresponding emergency plan.

Contingency Plan Process

The single-school command and dispatch system is a comprehensive communication system integrating video conferencing, command and dispatch, and real-time monitoring. It mainly comprises a server cluster with a visual command and dispatch server and a video conferencing server, an IP network video conferencing terminal in the command center, and a monitoring platform integrated through a video access gateway. The system supports smart terminals (such as law enforcement recorders) connecting to a VPN private network via 3G/4G/5G base stations to achieve functions such as group intercom, real-time video transmission, GPS positioning, SOS one-click alarm, and video conferencing. Simultaneously, relying on diverse network environments such as the campus private network, it links video access, hybrid intercom, and emergency command to form a three-dimensional command and dispatch solution covering remote collaboration, dynamic monitoring, and emergency response.

The Campus Visualized Command and Safety Dispatch System Solution, with its advanced technical architecture, rich core functions, and wide range of application scenarios, provides strong technical support for campus safety. Through the deployment and application of this system, schools will be able to achieve real-time monitoring, intelligent early warning, and rapid response to campus safety issues, effectively improving campus safety management. At the same time, the system will also help optimize emergency response processes and improve system performance, safeguarding campus safety.
