Design And Implementation Of Video Surveillance System Of Social Dynamics For Public Security Bureau

Public security bureau of the social dynamics of video monitoring system is an important part of intelligent security system, the system is in the social information display and record events, such as events to help officials later for analysis. Video monitoring system is indispensable an important part of prevention engineering. In this thesis, the analysis and research on the social dynamic monitoring of video monitoring system and the software to the client.Firstly of all, the development of video monitoring system are analyzed and the characteristics of video storage, then the concept of digital video monitoring system are analyzed, and the development of key technology and system planning need to solve the problem; Video monitoring system are emphatically analyzed video, image storage technology, this paper introduces the technical characteristics, video storage management cycle, solution and realization process, and introduces the development of image processing software technology and the environment.Secondly, analyzed the system construction goal, and then to the overall design of the video monitoring system, including the design objective, overall structure design, functional design, network structure design, etc., focus on the key technology of system design, design the alarm transmission device, monitoring management center system, the monitoring center called workstations, monitoring network management and service functions, and some auxiliary function of the system, and studies the design of video monitoring system data storage solution, the overall design of video monitoring system based on social security and management functions.Finally, the module of video monitoring system design and implementation, respectively designed: video monitoring hardware, communication service, monitoring network and monitoring the client’s design content; Then, designs the video storage system module, system of video storage, basic data processing, centralized and distributed storage design; Finally, the detailed design of the video image processing functions, including read, contrast of the image adjustment, grayscale, edge, binarization, calculated trajectory drawing functions, such as image processing of client acquisition of image analysis and processing for implementation.All in all, social dynamic video monitoring system of research, when dealing with daily security events, the public security bureau can make the work of communication barrier-free space, shorten the time consumption, reduce costs, speed up the information transmission. Dynamic video monitoring system, public security bureau of social security integration of video monitoring system, and makes the system runs stable and reliable, the construction of the monitoring system of the public security department, across space and time, cut off the remote monitoring of work, improve the business efficiency of the public security bureau, has higher application value.
