1. Cloud computing and big data
The era of security cloud and big data has quietly come, which will have an impact on the entire security ecological chain. Cloud computing promotes the transformation of business models in the security industry, and a number of security service companies will emerge to provide security cloud services including cloud storage, so that more people can enjoy security services. Big data can efficiently store and process massive amounts of data, including fast retrieval, efficient analysis, event prediction, pre-judgment, etc., so as to enhance the service capabilities of the security cloud and provide users with better services.
The impact of cloud computing and big data on the security industry is not independent, but complementary. While cloud computing is transforming the business model, more and more data is integrated, processed and shared. Massive data processing puts forward requirements on big data; the application of big data solves the problem of processing efficiency of massive data, and at the same time provides further in-depth The application lays the foundation and can enhance the service capabilities and value of Security Cloud.
However, cloud computing and big data are still in the early stages 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 blossom everywhere in the security industry, and the combination of cloud computing, big data and security will become closer and closer.
With the widespread application of network video surveillance, high-definition video has become the mainstream of the market. However, the current H.264 standard presents more and more limitations in the application of high-definition video surveillance. 1080P video images generally need to occupy 4~10M bandwidth, which brings greater 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 a higher compression ratio to video and reduce network and system construction costs. According to the security system construction model, network transmission and storage equipment usually account for about 50% of the construction investment. How to maximize the efficiency of reducing network bandwidth and storage space needs to be solved by video compression coding technology. The compression efficiency of the H.265/HEVC standard can be increased by more than 50% compared with H.264. According to estimates, the investment savings that may be brought by up to 20 %!
From the current point of view, the H.265 standard will certainly accelerate the popularization of high-definition products in the security industry, and will also change the cost structure of video surveillance products. However, in a short period of time, it is still too early for the large-scale popularization of H.265 in the security industry. In the future, with the increasing popularity of smart consumer electronic products, H.265 will become the mainstream of the industry under the promotion of civil security. choose.
3. Perceptual intelligent analysis
In the past, security was a closed field, and I focused on doing my own LAN and private network services. In the past few years, we have been on the express train of the Internet, and business applications have increasingly used the public network. In the early stage of achieving interconnection, the Internet of Things came again. The future is the era of the Internet of Everything, and the security industry must keep up with the pace. Some people think that security data running on the Internet is interconnected. The data obtained by the sensors and electronic tags of the Internet of Things is easy to process and use. The core part of the security industry is video surveillance. It has to be said that the insufficiency of intelligent analysis applications in the industry has hurt many users, and many companies have exaggerated the functions of their products. At present, intelligent analysis applications in the industry mainly focus on simple alarms and captured information. What users really want is a perceptual intelligent analysis device, which is equivalent to a visual sensor in the Internet of Things, which recognizes the content in the monitoring screen, and performs semantic description and the best picture capture on it, and then calculates it through the cloud The platform analyzes and replaces people's thinking and judgment.
Four, 4K Ultra HD
HD has already made H.264 unbearable. So the arrival of H.265 is inevitable. Although HD can now meet the basic needs of users, H.265, as a recognized 4K encoding method, cannot deny its role in promoting Ultra HD. How clear is 4K? A common 4K pixel count is 8 million, with a resolution of 3840×2160 (QFHD) or 4096×2160 (UHD), which is 4 times that of high-definition 1080P and 8-9 times that of quasi-high-definition 720P.
How much help can such a high resolution be for actual security applications? First of all, the most obvious feature of 4K technology is that the increase in display resolution makes the picture more refined. There are two important key factors that affect the fineness of the picture, one is the pixels of the picture, and the other is the vertical resolution of the picture. The higher the pixels of the picture, the finer the pixels on the picture of the same size, 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 levels the human eye can recognize. What 4K technology realizes in the monitoring field is to increase the pixels while enhancing the vertical resolution of the picture, making the details and levels of the picture more accurate. At the same time, with the special wide-angle monitoring lens, it can realize the coverage of a larger monitoring range.
Those who don't plan for the long term don't plan for a while. Especially the dependence of technology-based enterprises on technology is self-evident. Without technological innovation, its products cannot compete with others. In the future or in recent years, if any company masters these core technologies earlier and better, it will be in a favorable position in the industry competition.
