Overall solution of HD digital monitoring system
With the progress of science and technology and the development of computer network transmission and storage technology, video digital encoding and decoding technology, the application of video monitoring system in the security industry has made a leap forward development. The security video monitoring industry usually divides the development of video monitoring technology into several stages: analog monitoring, digital analog combined monitoring and full digital intelligent monitoring. As an epoch-making revolutionary product, the IP HD full digital intelligent monitoring system has solved many bottlenecks in the traditional sense after years of development. The IP HD era is coming! Firstly, the rapid development of video coding and decoding technology and computer storage technology has directly led to the possibility of network transmission and storage of high-definition images. We can effectively use the most advanced coding and decoding technology to compress high-definition images into an acceptable size that is easy to transmit and store, laying a solid foundation for the rapid development of high-definition systems; Secondly, the widespread deployment and rapid development of IP networks have promoted the emergence of network video monitoring. In fact, after the IP based video monitoring, especially the increasingly mature and perfect CMOS technology and the introduction of 720P and 1080P high-definition cameras, many broadcast level IP video technologies have been introduced into video monitoring applications in large quantities, in addition to the traditional sense of technical defense monitoring, It extends to the management level of all walks of life, making the application scope of video monitoring expand to a wider range; Third, because the IP high-definition camera has brought about a significant improvement in the quality of video images, a large amount of video capture information has provided sufficient analysis sources for various intelligent video analysis tools, which has greatly promoted the development of video monitoring to intelligent monitoring. With the maturity of the HD IP monitoring system, it can be expected that the HD IP monitoring system will eventually push the video monitoring system to the peak of digitalization, networking, and intelligence, and achieve a truly comprehensive application. At the forefront of the upgrade and reform of the video monitoring system, the Asia Olympic D (digital) I (intelligence) N (net) S (system) DINS system came into being, bringing a new construction and application mode by organically combining the high definition of images that the monitoring industry has been pursuing for years with the digitalization, intelligence and networking of the system. 3. Some contents and pictures of the scheme 1 Support IP SAN extended storage to achieve fast and high reliability. The storage of the IP monitoring system itself adopts an IP SAN professional storage architecture, so the equipment reliability is much higher than that of traditional DVRs, including support for various RAID protection technologies, hard disk hot backup and online maintenance, no data will be lost if any hard disk is damaged, and power redundancy is supported, which are not available in traditional DVRs. 2. Rich value-added services to achieve intelligent security. The IP monitoring solution can realize system linkage such as professional alarm, access control, SCADA, fire protection, intelligent analysis, etc., help users solve problems in cross system linkage integration and application management, greatly reduce risks in project implementation, coordination, integration, etc., and enrich various value-added applications of the system. In traditional monitoring, images can only be transmitted, monitored and recorded. It is impossible to analyze and process images. The IP based digital monitoring scheme enables video monitoring to integrate with intelligent services such as access control, alarm, intelligent analysis, intelligent tracking, traffic statistics, and realize real security automation. Network video monitoring is based on digital signal processing. It uses a networked way to realize signal transmission, exchange, control, video storage, and on-demand playback. It also establishes a powerful central business platform to realize the unified management and centralized control of all encoding and decoding equipment and video storage equipment in the system. For users, they only need to log in to the central business platform to realize the unified call and browsing of the whole network monitoring resources.
