1 system integration product integration In recent years, technologies such as cloud computing, cloud storage and big data have enjoyed rapid development in the Internet industry. Technology and products have been well tested by the market and have been widely recognized by the whole society. In the security industry, led by the objective demand of the market, mainstream vendors are actively introducing related technologies into the industry and evolving in line with industry characteristics to promote the rapid development of cloud computing, cloud storage and big data in the industry. Meanwhile, a series of broad Recognized by the market products and ideas, and cloud computing, cloud storage products have become the mainstream manufacturers in the safe city solutions one of the core system, which used the core technology has become a measure of the status of the company's industry Key indicators. Video monitoring technology trend one: the system integration of product integration Conform to the needs of business development, video surveillance products gradually emerged convergence industry trends. A host of modules can be deployed to provide a variety of services, such as storage, streaming media, management systems, computing units and other integrated deployment of products, or a persistent multi-virtual machine storage server. A product integration of a variety of software modules to provide an integrated solution, has a very good competitive advantage. However, in the meantime, the multi-module hybrid deployment requires relatively high resource requirements for each module because resource isolation is required under limited hardware resources, hardware performance is fully utilized, extra overhead is avoided, and flexible adjustment capability is required. Container technology which has many advantages, especially as a lightweight virtualization technology means, combined with a reasonable management software system, and application software system quota, will be a very good direction. Video surveillance technology trends II: formats tend to diversify Cloud computing, the development of the video surveillance industry under the age of big data shaped the diversification of business patterns. The Internet trend and application scenarios require innovation in the traditional video surveillance industry development model, such as lower stream, higher concurrency, live on-demand, more friendly terminal experience. At the same time, with the country vigorously promoting the construction of smart cities and safe cities, the video surveillance industry has also gradually integrated into the construction of other industries and formed a complementary advantage with other industries. As a result, video surveillance solutions have become the solutions of various industries The key part, so this video surveillance system platform openness, interface rationality and other performance put forward very high requirements. 2 Security is the real "Big Data" industry Security is the real "Big Data" industry Security is a real "big data" industry, with different characteristics from other industries, how to break the bottleneck of security data applications, bringing massive value, to the related technology presents a huge challenge. Security industry data comes mainly from the massive surveillance cameras to a high-definition camera (code stream of 4Mbps), a month produces about 1.2TB of data, and a medium-sized cities deployed up to tens of thousands of cameras, So a medium-sized city a month can generate dozens of PB video data accumulation. The face of massive video data, the traditional storage system does not improve the low value of the video data density problems, and the system construction cost-sensitive and cost-effective low prevalence of the problem. In this context, a high-performance system video cloud storage system that can meet the sustained and intensive reading and writing demands of video streaming data has emerged. Based on distributed storage technology, erasure code can be used to achieve the perfect combination of cost and reliability based on a low-cost storage server and low-end high-capacity disk, while providing optimization for video streaming features without loss of versatility The storage capacity of the object can meet the demand of the video storage business and accord with the open sharing requirement of storage for cloud computing technology development. The rise of cloud computing puts forward different requirements for the openness and read performance of video data. Therefore, the traditional block-based private video storage technology and related solutions will gradually lose their market competitive advantage. The increasingly accelerated development of SSD (Solid State Drives) storage technology, will also be the potential for the development of video cloud storage has brought significant changes.
