Abstract


The modern enterprise has been widely used as the core video surveillance system based on embedded server, in order to facilitate the control of business-critical nodes working condition and progress, recording and retrieval node information to improve management efficiency. The new situation under the new management of cross-regional cross-cutting management, so companies are not satisfied with fixed monitoring and management of a single node, but also to achieve cross-regional, multi-client remote monitoring node parallel data acquisition and implementation of management new demand. The author analyzes the development status from the field of video surveillance and demonstrates the potential problems in the current video surveillance system architecture, the establishment of ADSL new embedded video surveillance system architecture-based system. First of all, to a more mature dynamic sensing algorithm, and modify the pitfalls inherent in the known algorithm established a new algorithm theory based on experimental data in the simulated environment, and the specific implementation of the project will be in the enterprise algorithm theory to the new structure of the embedded server system, and then use the actual test data, the algorithm was verified in the application system, making the new structure embedded video monitoring system has a 24-hour unattended monitoring client node automatic monitoring alarm recording function; Second, the principle of ADSL with DDNS technologies, analysis, discussion and establishment of functional structure of the remote monitoring terminal on the video server Web access and video transmission mode using a combination of the two technologies in a new system architecture and implementation of method, combined with a good selection and positioning of the digital image and video compression standard MPEG4 video surveillance system under the new system architecture with high-quality remote screen transmission effect. In the field implementation of the new system architecture as the core embedded video monitoring system applications, enterprises realized via ADSL Internet network for the media, a internal precious metals warehouse Accessible Distance WEB monitoring and management; 4-way monitoring screen at the same time transfer case, access to high-quality monitoring transmission screen resolution of 320 x 200dpi, 25 frame / sec; reached offsite storage monitoring node data to ensure data security target, get a good evaluation of the enterprise, at the same time also made a guidance for the future development direction of the video surveillance system with the pre-research trends.
