【System Content】

The driving force behind the in - depth development of the security industry stems from people's needs. Nowadays, the management of security systems is no longer simply about constructing separate video surveillance, access control, or anti - theft alarm systems. In terms of integrated management, on the one hand, it is hoped that the above systems can be organically integrated, and they also need to be linked with business systems. This requires that in the overall design, the system structure configuration should be advanced and practical, and the system application management should be linked.

Conventional security systems involve the following subsystems:

1）Video surveillance system;；

2）Perimeter protection system;

3）Access control system;

4）Anti - theft alarm system;

5）Intelligent analysis system;

6）Interface docking between the system and business systems such as GIS and integrated management.

In the structure configuration of the network video surveillance integrated management system, each subsystem (such as audio - video surveillance and recording system, anti - theft alarm system, remote control, remote voice intercom, and remote network transmission system) can be deployed relatively independently. Then, communication and linkage are carried out with the video surveillance system as the core. According to needs, the intelligent analysis system and business systems are linked to achieve the complete integration and seamless connection between subsystems, that is, to realize a system that is organically reasonable, easy to maintain, and mutually linked.

【System Integration】

For integrated management, it is ideal if a single platform can achieve centralized control of each subsystem. However, due to the inconsistent development levels and industry standards of each subsystem, this idea is almost unfeasible at present. The solution then becomes to use a certain system as a link for linked management to achieve the effect of 1 + 1>2.

In terms of digitalization degree and management requirements, the author believes that based on the network video surveillance system, by integrating information sources such as voice, alarm, and access control, visual management can be achieved. By combining with systems such as intelligent analysis and having the system background automatically analyze, intelligent management can be achieved. By docking and integrating with business systems such as GIS, integrated management can be achieved.

【Prospect】

With the increasing demand for security, managers hope that the system is more comprehensive, and users hope that the system is more timely. The definition of security systems is also gradually evolving. From single access control, alarms, and video surveillance to the integration of intelligent analysis, GIS, and business systems, there are more and more security subsystems. However, while the increase in subsystems meets diverse needs, it also increases the complexity of the system, which puts forward higher requirements for the scientific nature of system design and system integration.

With the development of network technology and the in - depth digitalization of each subsystem industry, especially as video surveillance enters the high - definition era, by using the video surveillance system as a hub to integrate information sources such as voice, access control, and alarms, and then providing interfaces to connect to business systems, and even using the geographic information system as a display platform, this series of integrations based on the concept of soft integration have well overcome difficulties in terms of standards and interfaces, scientifically ensuring the collaborative work between systems and constructing a complete and expandable security integrated management system.

With the expansion of the application fields of security systems and the in - depth development of industry solutions, the security systems in fields such as public security, transportation, finance, and education in the future will surely have more scientific management with industry characteristics. In the future, system integration will also see industry convergence based on the needs of urban management and social management.
