With the continuous development of monitoring technologies and requirements, the deployment scope and system scale of video surveillance applications have also gradually increased. Campus network monitoring has become the most important market in the field of security surveillance, and its scale and complexity are also increasing. For example, in the Shanghai Expo Park, which was formally put into operation in May 2010, in addition to the more than 10,000 surveillance cameras built by each stadium, only the surveillance video directly under the Expo Command Center is as many as 3,800, and the park’s The monitoring system also effectively cooperates with GIS, passenger flow analysis and traffic management systems, and integrates monitoring screens and intelligent analysis systems to upload information and provide integrated management services such as emergency command and real-time dispatch.
What is park monitoring
The so-called park monitoring means that within a fixed perimeter, there is a certain scale of monitoring systems with related application linkages. The monitoring coverage of the park is relatively large. It usually involves multiple buildings. The management has relative independence and completeness. Generally there is a certain perimeter; at the same time, the company/unit that owns the park network usually also owns the physical lines used in the park.
The park is the most common geographical area involved in the production, office, and life activities of current social organizations (plants, mines, enterprises, institutions, etc.). Therefore, it is also the most widely used type of IP surveillance networking. Park monitoring covers major monitoring applications in multiple industries such as enterprise parks, campus parks, government office parks, prisons, ports, and airports, and is mainly applied in the following two aspects.
One is the field of security monitoring. In other words, video surveillance is used as a technical defense means to prevent theft of property and intrusion of busy personnel. It provides real-time weather monitoring of the destination, entrances, factories, office buildings, perimeter fences, warehouses, and other targets. It also has surveillance videos. , alarm linkage and other functions, become an aid to security work.
The other is the field of production monitoring. In some specific industries, in order to strengthen management and improve work efficiency, monitoring will also be used to assist the production system, which is usually called production monitoring. In this case, video monitoring is used as a management means, for example, a manufacturing company uses video surveillance for The visual management of the production line, the school will use video surveillance as a means of remote proctoring. In this case, the choice of monitoring points is more dependent on the needs of business and management, and is generally set in the main production service area.
Four key requirements for campus monitoring
For the campus monitoring, on the one hand, the user's control experience on the video surveillance system itself requires more and more humanized, such as high-definition picture display, event-based video fast retrieval accurate positioning, three-dimensional simulation GIS and configuration, etc.; on the other hand The user's positioning of the video surveillance system is no longer an isolated video image acquisition and reproduction system, but is an integral part of the security system or other professional application systems. The video surveillance system should be connected with other subsystems of the security system (such as access control and alarms). , Firefighting, etc.), or other subsystems of professional application systems (such as SCADA power environment systems, time and attendance systems, image intelligence analysis systems, etc.) to achieve full integration and interaction. In addition, with the expansion of the scale of the park or the continuous joining of branches of enterprises and institutions (such as branch schools, branch factories, and off-site plant sites), the demand for cross-domain networking and unified application management of multi-site monitoring systems will increase. In this situation, many changes have taken place in the demand for park monitoring. There are four key issues that need to be addressed.
The first is the requirement for scalability and the use of existing resources.
With the expansion of the park's scale and the continuous participation of branch offices of enterprises and institutions (such as branch schools, branch factories, and off-site plant sites), the monitoring scale and density of the park have increased a lot more than before, and IP-based network monitoring has gradually become mainstream. At the same time, there will be more and more demand for integration of existing monitoring resources and cross-domain networking of multi-site monitoring systems.
Followed by the unified management of global resources.
After more and more IP technologies have been integrated into the video surveillance field, it has become possible to share and integrate services with different purposes, such as security monitoring and production monitoring, in the video surveillance system. This has led to the further expansion of the monitoring scale. The system needs to manage a large number of monitoring resources in a unified manner, maintain a large number of front-end equipments, and improve the efficiency of fault discovery and processing.
Again, it is the integration of openness and business applications.
With the continuous development of video technology, security technology and IT technology, on the one hand, the user's control experience on the video surveillance system itself requires more and more humanized, such as high-definition picture display, event-based video fast retrieval and accurate positioning, 3D simulation GIS and Configuration, etc.; on the other hand, the user's positioning of the video surveillance system is no longer an isolated video image acquisition and reproduction system, but an integral part of the security system or other professional application system, video surveillance system needs and security system Other subsystems (such as access control, alarm, fire, etc.), or other subsystems of professional application systems (such as SCADA power environment system, time and attendance system, image intelligence analysis system, etc.) are fully integrated.
There is a requirement for reliability. With the increasing importance of video surveillance systems in security systems, the reliability of the system has become more and more important. From the reliability of the front-end equipment to the reliability of the network link, the reliability of storage, and the reliability of the management platform, they all need to be upgraded on the basis of past monitoring systems.

Faced with the ever-increasing construction demand, what developments and changes will occur in the campus network monitoring and how to effectively deal with these issues is the key we must consider.
