First, system overview
Video surveillance as a high-tech security means its importance is self-evident. In banking finance, transportation, public security, electricity, justice, public transport and other industries, with the continuous improvement of the level of security monitoring, the number of monitoring equipment and the amount of information are also increasing rapidly, and the difficulty of management is increasing. Previous field equipment control has been followed. Not on the development trend of security monitoring, the traditional monitoring methods are also difficult to quickly and timely analysis of monitoring information processing, low level of automation. Therefore, by establishing a highly integrated centralized management platform, remote control of front-end equipment, remote call and analysis of monitoring information, and operation and maintenance management of monitoring equipment have become new requirements for security monitoring. This raises higher requirements for management servers, such as central management servers, storage management servers, professional and reliable system integration platforms, and integrates video monitoring, alarm systems, intercom systems, and access control systems, and integrates unified scheduling management.
Second, the system requirements
The server must have many advantages such as high transmission speed, compatibility and security. With Xeon's multi-core processor, it has high performance, high reliability and flexible configuration and scalability, enabling more economical and faster application expansion. The humanized design incorporates professional server operating system software. There are two places in the industry that use servers: central management servers, storage management servers.
Third, the system description
Security monitoring industry common solutions are mainly divided into front-end monitoring layer, center management layer, and business processing layer.
The central management server and storage management server belong to the central management level.
Central Management Server: User Management (Permission Verification, Log Management), Device Management (Front End Device Management), Organization Management (Business Client Management)
Storage Management Server: The audio and video data storage coming from the DVR is packaged by the server and stored in the IP SAN. A set of "timing synchronous storage" and "timing asynchronous storage" strategies can be defined on the server for each video for each collection point. If a policy is defined, the system will automatically start/stop collecting data from the front-end device and store it on the hard disk of the server according to the policy timing. The description information of the data file will be stored in the database. The user can automatically query all the video data authorized to him. Information and on demand.
The network storage management service includes the functions of system authentication such as resource verification management, user management, WEB service, and centralized storage. It adopts the Windows Sever 2003/2008 operating system and can implement multiple server clusters and cascade management.

As we all know, high-definition images are clearer, more detailed, and more accurate. However, the high-definition monitoring brings about the transmission, storage and analysis of massive HD data, which not only imposes higher requirements on the product technology of the entire monitoring system, but also puts great pressure on the system cost. These have become major market obstacles for large-scale popularization of high-definition and intelligent surveillance. At present, EVOC has cooperated with a large number of video surveillance product manufacturers and integrators, and its industrial server products are in many areas of the Safe City project as well as banks, large and medium-sized branches/branches, networked centralized monitoring and management systems, subways and other monitoring projects. Got applied. The important role of EVOC Industrial Server in the video surveillance system is to make security and IT inherently relevant and to secure IT products in the backend. To solve the obstacles that hinder the development of the market of high-definition and intelligent video surveillance, using the most advanced IT technology is absolutely an effective means. The EVOC Industrial Server has higher reliability, processing capacity and scalability, and can fully meet the data storage and processing requirements of high-definition and intelligent monitoring.
