Design And Implementation Of Video Surveillance System Based On IP Network

As the socio-economic development, the emphasis of our security system is a gradual increase in the first decade of the21st century, China’s security industry has been rapid development in the residential area of safety control on hospital care wardobserve aspects of patient safety, personnel safety protection in the important commercial centers, schools and government agencies have video surveillance figure. As electronic technology continues to progress, the field of security industry continues to expand, more and more types of security products, relate to various industries and areas, for the protection of the commercial interests of the individual or collective property rights and inherent assets plays an irreplaceable role.In this paper, in a lot of preparation work system built pre-building and laid a solid foundation for the smooth progress of the system. The main content of the paper include:1.The development of video surveillance systems:Introduction to the development of a video surveillance system, from first-generation analog video surveillance system, and half to the second-generation digital video surveillance system, and then to the third-generation digital video surveillance system, a detailed description of thethe advantages and disadvantages of each, and analysis of the prospects for the development of the future under the conditions of an IP network video surveillance system.2. Video surveillance system architecture:the architecture of the video surveillance system description and analysis of a video surveillance system in the central platform consisting of four levels, each level is introduced. System requirements, and finally the network video surveillance system based on broadband eh, such as point-to-point implementation of network.3. Information storage technology:We introduce a centralized information storage technology, DAS, NAS, SAN and iSCSI, the specific contents of these storage protocols, their strengths and weaknesses, is a microcosm of the development of storage technology. Details of the basic principles of the iSCSI protocol, communication theory, and IP protocols, and the relationship between iSCSI and SCSI.4. Video surveillance system construction:the development of video surveillance systems in this article is based on DirectShow technology is based on windows operating platform, system design and implementation, the system achieve up to16-way video models while monitoring, and can automatically switch the lens paper log system to build a video surveillance system, run clear and complete record system, the use of the user’s convenience for normal use and maintenance of the system.
