| As web technology, video surveillance technology has been development, but there is still some Inadequate in the development. In order to solve the existing problems of video surveillance systems. Design and implement a credible high-compression video surveillance system based on a new generation of rich internet application technology Flex technology and FMS technology .System of using Flex technology greatly improves the user experience of video surveillance systems. Flex greatly reduce the burden on the server with powerful data processing and business logic capabilities. FMS technology can facilitate the realization of a simple extraction of online video. By using Adobe's latest F4V video encoding, a very small volume can get higher video resolution, while also reducing the network transmission delay.This thesis is presented in the following several parts. then, the video surveillance system related technology is introduced. the characteristics of the Flex technology is described. The differences are between Flex technology and the traditional B/S structure technology. We introduced Flex related technology, FMS technology and F4V streaming video encoding formats, and the video surveillance system used Flex technical .Then, we introducted the system requirements analysis, functional structure of each module. the important part of this article ,Flex-based video surveillance system technology , design and implementation part describes the Flex technology and FMS ased on B/S structure of the system design structure of the system design, also made a description of each module: the user login screen, user registration interface, the administrator management interface, the device management interface, the device management interface ,online video storage modules, video modules asynchronous online storage ,online streaming video on demand module ,online video to achieve playback module is in the next setp . these modules detailed description and annex of the program code. then we describes the performance tests , including software testing, functional testing module. Finally, there is the summary of the results and shortcomings, we can continue to improve the places described.As a result of this short thesis written in Flex technology, video surveillance system with interface performance ability, excellent support for multimedia, can provide a good user experience; while using the F4V HD video encoding format and improve the integrated use of motion detection algorithm, so to achieve the credibility of this thesis, high-definition compression requirements. |
