The Application And Improvement Of Video Surveillance System In Investigation

With the " use science to arm police " concept of deepening, installation construction " Skynet project", " Golden Shield Project", "Green City " of the building as well as a large number of advanced video surveillance systems, video surveillance systems used in practice as if the investigation opened up a new, fast, high-energy detection means. But with the current construction of the high frequency of video surveillance systems, a very wide range of coverage, the use of high-intensity compared to the relatively weak video surveillance investigative research in theoretical circles that have not yet reached a uniform title for the video surveillance system in the investigation the application of the definition, can not give the theory in practice and guidance bedding, Moreover, the video surveillance system has a large number of problems in the investigation of the application : the regulatory body, the whole fabric construction, staffing, work mechanism, technical construction, maintenance, management, information sharing and resource preservation and other aspects of the investigation as a constraint to the problem of video surveillance lies. So find a full range of questions, the perfect remedy formula proposed initiative is not only an urgent task, but also a video surveillance system to provide theoretical support in the investigation of the application.This paper is divided into five parts, the main contents are:The first part is about the basic concepts of video surveillance systems comb. Current use of more concepts for analysis, such as video investigation, criminal investigation video, video detection technology, video detection, video surveillance systems, video surveillance data, identification of certain video image analysis, and finally that " Video Surveillance investigation " to define the concept of the video surveillance system in the investigation of why the matter.The second part is the application and comparison of foreign real video surveillance system in the Investigation. This section first describes the application status select the UK, the US, Japan, the three representative countries presented their development status and application process, then back home perspective, mainly introduced in China started earlier, more large scale development in Guangdong( Guangzhou, Huizhou), Tai zhou, Hangzhou describe the reality of their respective applications.The third part is the video surveillance system application value and functionality in Investigation. First introduced in the use of video surveillance systems detect fundamental value, mainly reflected in: the value of efficiency, safety, value and order of value; after the introduction of the video surveillance system in the investigation of the application of functional manifestation concept from the micro, macro three angles.The fourth part is the video surveillance system in the investigation of the application of the existing problems. From a different perspective, Can be summarized as the main deployment between multiple clutter, lack of regulatory body; a lack of systematic layout planning, poor post- use effects; yet professional team overall, comprehensive quality is not high; the lack of appropriate practices, working mechanism has not been established; technical construction in its infancy, the application root out too facile; heavy construction, light use, management and maintenance of lax lag; information preservation big shortfall of inadequate protection of privacy of citizens; by restricting the sharing of resources, poor utilization efficiency.The fifth part is perfect countermeasures about video surveillance system applied in the investigation. Unified regulatory body, more harmonious operation of the mounting body; the overall planning and steadily built fabric, numbers positioning system to achieve convergence; established professional team, improve the level judged; focus on training staff awareness and application of literacy skills; management and front-end monitoring equipment maintenance, pto provide protection for the overall operation; strictly limit the scope of the program video information, taking into account the mutual benefit of shared resources.
