In the market Wuxi Monitoring Introduction to the development direction of
Wuxi Dehang Technology Co., Ltd The monitoring system is one of the application systems in the security system. Now the more suitable site monitoring system in the market is handheld video communication equipment, and video monitoring is now the mainstream. From analog monitoring to hot digital monitoring a few years ago and now to the emerging network video monitoring, earth shaking changes have taken place. With the gradual unification of IP technology in the world today, it is necessary for us to re understand the history of video monitoring system. From the technical point of view, the development of video monitoring system is divided into the first generation of analog video monitoring system (CCTV), the second generation of digital video monitoring system (DVR) based on "PC+multimedia card", and the third generation of completely IP based network video monitoring system (IPVS).
With Wuxi remote monitoring The development of network technology, recognition technology, microelectronics technology, encoding and decoding technology, operating system technology, etc. will make embedded DVR develop in the direction of intelligence, integration, wireless, high-definition, personalization, and interaction.
1. Hardware processing speed is faster and storage time is longer
With the development of chip technology, the higher performance CPU makes DVR faster and more powerful. From earlier CIF Digital Video Recorder , D1 hard disk video recorder, 960H hard disk video recorder, hybrid hard disk video recorder, HD-SDI hard disk video recorder. In addition, along with Wuxi Security Monitoring With the trend of high-definition, the demand for storage is also increasing, and DVR hard disk management technology is also improving. Basically, DVR may support more hard disk interfaces, RAID technology, and compatibility of storage technologies such as DAS, SAN, and NAS.
2. More advanced coding mode
The mainstream DVR compression technologies in the market are MPEG-4, H.264, M-JPEG. MPEG-4, H.264 are common compression methods in China, and H.264 has become the mainstream because it is more suitable for network transmission requirements. In order to make embedded DVR more widely applicable in the future, the unification of various algorithms will be the trend of future development. However, this unification is not based on the standards of which domestic enterprises, but requires the extensive participation of a wide range of government functional departments and various enterprises in the DVR industry chain. For example, the AVS compression algorithm with independent intellectual property rights in China and the H.265 compression algorithm have revolutionized in many aspects compared with H.264.
3. Intelligence is an important development direction
From the technical point of view, intelligence is an important development direction. Only through intelligent analysis technology for video information management can people's work be freed from complicated affairs. In fact, the functions of real-time monitoring, early warning, information processing and retrieval all need intelligent technology applications. Although it is difficult to fully realize the management of intelligent analysis technology in a short time, the technology can already achieve semi-automatic monitoring intelligence to some extent. In most cases, the use of intelligent analysis technology can complete most of the work, and staff can focus on management and coordination. This is a good application mode at this stage. In terms of intelligence, the market demand is strong. Many manufacturers have launched DVR with intelligent analysis technology. The current intelligent analysis technology also does not have 100% accuracy, and the technology still needs great breakthrough and progress to meet the market application.
