Digital Video Recorder Test Method Of Research And Application

Digital video recorder uses the hard disk video, so it is often referred to as the hard disk video recorder. In recent years with the development of computer technology to gradually developed video surveillance equipment. It is include computer network technology, digital video technology and the traditional Video surveillance technology with the combination of high-tech product. Multi-function security detection system, the production of security products and security engineering with the specified methods test some or certain kinds of specified technical performance index of the technical.In this paper, digital disk recorder detects an example, the multi-function security device detection system research and design, according to the digital disk recorder test content and testing standards, testing research and analysis, in order to build a digital versatile disk recorder detection system.DVR thesis describes detection methods and significance, based on the national standard GB20815-2006based on the detection of content and technology indicators, complete multifunctional detection system design and implementation. And Digital Video Recorder is an object, the completion of the functional test, system test results meet the technical requirements. Finally, for the national standard GB20815-2006is unreasonable given their own proposals at the same time describe DVR common fault and gives corresponding solutions.
