    Four Technologies for Left and Right Security in the Future

    time:2019-04-28 Publisher: Number of visits:827次

     First, the era of cloud computing and big data < br/> Security Cloud and big data has come quietly, which will have an impact on the whole security ecological chain. Cloud computing promotes the change of business model in security industry, and a number of security service-oriented enterprises will emerge, providing security cloud services including cloud storage, so that more people can enjoy security services. Big data can store and process massive data efficiently, including fast retrieval, efficient analysis, event prediction, pre-judgment and so on, so as to enhance the service capability of Security Cloud prevention and provide better services for users. The impact of cloud computing and big data on security industry is not independent, but complementary. While cloud computing transforms business model, more and more data are integrated, processed and shared. Massive data processing puts forward requirements for large data. The application of large data solves the problem of processing efficiency of massive data, and lays a foundation for further in-depth application, which can improve the service capacity and price of security cloud protection. Value.
    However, cloud computing and big data are still in the initial stage of development, the business model of cloud computing is not mature enough, and the business application of big data is not deep enough. It is believed that in the near future, cloud computing and big data will flourish everywhere in the security industry, and the combination of cloud computing, big data and security will be closer and closer. With the wide application of network video surveillance,
    2 and H.265
    high-definition video has become the mainstream of the market. However, H.264 standard shows more and more limitations in the application of high-definition video surveillance. 1080P video image usually takes up 4 ~ 10M bandwidth, which brings great cost pressure to network and system construction. Bandwidth, cost, technology and other reasons have become the bottleneck restricting the rapid development of the industry to high definition. The maturity of
    H.265/HEVC technology will bring higher compression ratio to video and reduce the cost of network and system construction. According to the security system construction model, network transmission and storage equipment usually account for about 50% of the construction investment. How to reduce network bandwidth and storage space to the maximum efficiency needs to be solved by video compression coding technology. Compression efficiency of H.265/HEVC standard can be increased by more than 50% than that of H.264. According to estimates, investment savings may be as high as 20%.
    At present, H.265 standard will certainly accelerate high-definition products in security industry. The popularity of video surveillance products will also change the cost composition. But in a short time, it is still too early for H. 265 to be widely used in the security industry. In the future, with the increasing popularity of intelligent consumer electronic products, H. 265 will become the mainstream choice of the industry under the promotion of civil security. < br /> 3. Sensory Intelligence Analysis < br /> & nbsp; & nbsp; & nbsp; & nbsp; Previously security was a closed area, dedicated to their own LAN, private network business. In recent years, with the rapid development of the Internet, business applications have increasingly utilized the public network. In the early stage of realizing interconnection, the Internet of Things came again. The future is an era of interconnection of all things, and the security industry must keep pace with the rhythm. Some people think that security data is interconnected when it runs on the Internet. Data acquired by sensors and electronic tags in the Internet of Things is easy to process and use. Video surveillance is the core part of security industry. It has to be said that the shortcomings of intelligent analysis applications in the industry have hurt many users, and many enterprises exaggerate the functions of products. At present, the application of intelligent analysis in the industry mainly stays in simple alarm, snapping information and so on. What users really want is a perceptual intelligent analysis device, which is equivalent to a visual sensor in the Internet of Things. It recognizes the content of the monitoring screen, describes its semantics and captures the best picture, and then carries on the analysis through the cloud computing platform to replace people to make thinking and judgment. The < br /> 4K and 4K ultra-high definition < br /> HD has made H. 264 suffer from unbearable pain. So the arrival of H. 265 is inevitable. Although HD can meet the basic needs of users, H. 265, as a recognized 4K coding method, can not deny its role in promoting UHD. How clear is 4K? The common 4K pixels are 8 million, the resolution is 3840 *2160 (QFHD) or 4096 *2160 (UHD), which is 4 times higher than 1080P and 8-9 times higher than 720P. How much help can < br/> such a high resolution bring to practical security applications? First of all, the most obvious performance of 4K technology lies in the improvement of its display resolution, which makes the picture more fine. There are two key factors affecting the accuracy of the picture, one is the pixel of the picture, the other is the vertical resolution of the picture. The higher the pixels of the screen, the finer the pixels on the same size screen, and the smaller the lattice. The human eye is very sensitive to the vertical resolution of the image. The higher the vertical resolution, the more details and layers the human eye can identify. In the field of monitoring, 4K technology not only improves the pixels, but also enhances the vertical resolution of the picture, which makes the details and layers of the picture more precise. At the same time, with the wide-angle monitoring special lens, it can achieve a wider coverage of the monitoring range. < br /> summary: < br /> those who do not think long-term are not short-term. Especially, it is self-evident that technological enterprises depend on technology. Without technological innovation, its products will not compete with others. In the future or in recent years, if any enterprise grasps these core technologies earlier and better, it will be in a favorable position in the industry competition.
