The development of video surveillance technology can be divided into three stages, namely, the analog video surveillance phase that began in the 1970s, the digital video phase that began in the 1990s, and the intelligent network video surveillance phase that has emerged in recent years. Let's take a look at the related content with the security electronic editor.
(1) Analysis of the stage of industry developmentFigure 1: Analysis of the development stage of video surveillance technology
From the perspective of the industry chain, the upstream is mainly for processing chips, optical devices, and algorithm providers; the middle reaches are monitoring equipment manufacturers and system integrators; the downstream is end users.
Figure 2: Video surveillance industry chain
Processing chips mainly refer to the key chips of devices such as decoder cards and DVRs. At present, most of the domestic DSP chips are used in China. Huawei HiSilicon has also developed integrated chips to make the video back-end devices easier to manufacture, but it also limits Customized space. At present, in general, chip providers are mainly foreign.
The optical device mainly refers to the CCD imaging device in the camera, because the front-end imaging accuracy is the primary determinant of the video monitoring effect. At present, many domestic and Korean manufacturers such as SONY and Samsung are selected.
Video and audio algorithm provider: At present, the domestic AVS algorithm with its own copyright is the main one.
(2) Development of the mid-stream industry--Hikvision has been the first in the world for six consecutive years.The monitoring equipment mainly refers to the back-end DVR digital hard disk recorder and NVR network video recorder, video and audio decoding card and various types of cameras at the front end. The strength of domestic equipment manufacturers is strong. According to IHS's “2016 Global Video Surveillance Equipment Market Research Reportâ€, Hikvision's global market share in video surveillance increased from 19.5% in 2015 to 21.4% in 2016. For the sixth consecutive year (from 2011 to 2016) IHS has the world's largest market share in video surveillance. From the perspective of equipment development, the main focus is on digital and networked equipment growth, and the proportion of analog equipment is already very low.

From the perspective of downstream industry distribution, Ping An City and Intelligent Transportation are the two areas with the greatest demand in the security industry, accounting for 44% of the market share. In the field of video surveillance, the two are also the largest demanders, accounting for 34% of the total.
Figure 4: Video surveillance application area (unit: %)
As an important part of security products, video surveillance products account for about 50%. During the period of 2014-2016, the proportion of video surveillance in security products applications was 47.06%, 48.33% and 50.63% respectively. During the period of 2010-2017, the scale of China's video surveillance market increased from 24.2 billion yuan to 112.4 billion yuan, with an average annual compound growth rate of 24.53%.

At the same time, China's camera coverage density is still relatively low compared to developed countries such as the United States and the United Kingdom. The United States has an average of about 96 surveillance cameras per 1,000 people. The UK has an average of about 75 surveillance cameras per 1,000 people. The city has fewer than 40 cameras per thousand people. Therefore, video surveillance still has a large room for development in China in the future.

The expressway distance is long and the traffic volume on the expressway is large. Therefore, it is necessary to rely on the highway video surveillance system to have a specific and macro control of the expressway's operation status, so as to realize the dispatch and guidance of the expressway traffic vehicles. To ensure the smooth passage of the highway. On the one hand, the highway video surveillance system can provide real-time, accurate and reliable traffic information for the traffic management department; on the other hand, it can effectively improve the monitoring efficiency and effect of highway traffic events, so as to quickly discover traffic events, which is conducive to timely implementation. Rescue, real-time traffic diversion and avoid secondary accidents, improve the safety of expressway traffic, and maximize the operational efficiency of expressways.
Highway video surveillance has a wide range of applications and application scenarios on the expressway, including road monitoring, tunnel monitoring, tunnel entrance and bridge monitoring, toll lane and toll booth monitoring, toll plaza and service area monitoring. In recent years, China's expressway construction has developed rapidly. By the end of 2016, the national highway mileage exceeded 130,000 kilometers.
According to the public data of China Highway Network, Ministry of Transport and China Knowledge Network, by the end of 2020, the country will open 165,500 kilometers of expressways, an increase of more than 37% compared with 2015, and will maintain a relatively fast growth rate. In addition, in addition to the incremental highway sections requiring new video surveillance equipment, with the advancement of technology, the stock highway video surveillance system also has the need for replacement. The development of highway video surveillance systems in China has evolved from the transmission and application of the earliest analog video optical transceivers to the integrated transmission phase of optical platforms in the mixed analog and digital scenarios. The all-digital monitoring system has undergone a revolution in the transmission mode of the three-generation highway video surveillance system.

With the construction of China's road transportation infrastructure and the acceleration of the construction of “Safe Cityâ€, the “13th Five-Year Plan†period will remain an important period for the development of China's video surveillance industry. Video surveillance will also extend to grassroots and underdeveloped areas, such as Urban and rural areas, urban villages, small towns, administrative villages, natural villages, etc. It is estimated that the annual growth rate of China's video surveillance market will reach about 10% during the “13th Five-Year Plan†period. That is, the scale of China's video surveillance market is expected to reach 155.8 billion yuan by 2020, and it is expected to exceed 190 billion yuan by 2023.

A waterproof slip ring is a type of sealant that can be used to create a watertight seal between two surfaces. This seal can be used in a variety of applications, including plumbing and automotive manufacturing. Waterproof slip rings are often used in conjunction with other types of seals to create a watertight system. It enables liquid and gas to flow freely between the two, without any leakage. This essential technology is used in a variety of industries, from automotive manufacturing to food processing.
Waterproof slip rings are mainly made of silicone rubber. They can be used in harsh environments and have a long life span. Silicon is an inert material and does not corrode in water or other liquids. It also has a low coefficient of friction, which makes it ideal for use in moving parts. Slip ring motors are typically used in high-power applications where large amounts of the current need to be transmitted. They are made of copper or aluminum to provide good electrical conductivity.
The Oubaibo waterproof slip ring is very popular on the market. It is made of high-quality materials and has a long lifespan. The slip ring is also very easy to use, and it can be connected to a wide range of devices. Additionally, the slip ring is Ethernet-enabled, which makes it perfect for industrial applications.
