The Design Of The Monitoring System For Urban Public Order Dynamic Video

With the rapid development of urban economy and urban construction, the explosive increase of the urban population and the floating population brings great pressure to the public security. The urban public security has been the top priority among priorities of the society public security. The security has been one of the most important criterions in weighing the urban modernization. A city without security would be far from modernization never mind a civilized city no matter how prosperous its ecology is. With the development and demand of society, the monitoring system for urban public order dynamic video must come to one of the important criterions in weighing the modernization of a city from now on.The monitoring system for urban public order dynamic video aims at cracking down and preventing a crime. The video monitoring points are set on the spots with complicated order, the key positions, the key streets, the districts of the crime and the key crossings. The monitored images are transmitted to the public security organs and other related departments. The public security organs and other related departments know and master the dynamic conditions of the order in the monitored regions visually by scanning and recording the images by which the management level for society order is improved efficiently.The quantity and quality of video image information system are often looked as important targets in weighing the government's management of a city and the ability of prevention and control system for public security. Keeping peace and security depending on science and technology is the guarantee in constructing a peaceful city while the monitoring system for urban public order dynamic video as a valid method in achieving the safety precautions has practiced a lot in many cities in China. It is not realistic to increase the police unreasoningly although the police numerical strength is relatively inadequate. So the introduction of safety precautions depending on technologies is necessary in solving the present contradiction between'effective management' and 'economic cost' in the police system and the urban management system. The monitoring system for urban public order could achieve dynamic monitor to the key crossroads, the key districts of trade communities and the spots with complicated order. The administrative staff could get the visual information and real-time dynamic state of the monitored regions at the first time. The system could be combined with the 110 alarm, the region networking alarm, the wire and wireless communication, the information process and the traffic guidance which plays an important role in keeping the peace and preventing and cracking down a crime.The influence bought by the monitoring system for urban public order to the community public safety is self-evident. The system could achieve searching around the scene, recording the images and tracking the suspects after the accident. What is more important is that it would deter the suspects.According to the requirement of the public order situation and the actual situation of regions the paper builds the network stretching over analogy and digital multilevel video transmission and achieves the real-time monitor to the front end video. The monitored video in the area under jurisdiction is switched in the police station and after being compression coded the video from the police station is switched in the network special for the police. The monitor centre of district (county) level and city level could control and transmit multiplexing images simultaneously and call the next lower level image information. The monitor centre of province level could retrieve the monitoring video of relative video monitoring points through the video monitor platform and upload some relative video information according to the order from Ministry of Public Security. Four levels network forms the star configuration based on the network special for the police and constitutes a dynamic video monitoring network interconnecting among the whole province.
