First, the explosive growth of high-definition monitoring At this year's Beijing Security Exhibition, whether it is the outdoor advertising of the exhibition hall or the booths of enterprises in the museum, the focus of the exhibition is not just HD, HD, or HD. Video surveillance vendors only have three main points of publicity: high-definition smart, the entire line of product supply, the industry's overall solution. Almost all monitoring equipment manufacturers are aware of the importance of the full range of products in the market competition. In addition to several years ago, it has already proposed to provide a full range of video surveillance equipment suppliers in the world Albert, in recent years, Hikvision began to launch a full range of monitoring equipment and enter the field of system integration, Dahua, Skyworth Qunxin, Dejiala also began Do network HD cameras. The same trend is also spreading in analog surveillance equipment vendors. Regardless of the size of the manufacturer, the product line is continuously expanding, and the entire line of products and providing total solutions have become “necessary†for market competition.
Second, the acceleration of the capitalization of security companies, the rapid growth of leading enterprises In 2011, security companies ushered in a intensive wave of listing. Hikvision, the leading company in the video surveillance industry in China, is listed on the Shenzhen Stock Exchange. Immediately thereafter, Shenzhen Das Intelligent Co., Ltd. was listed on the Shenzhen Stock Exchange; Shenzhen Infino Technology Co., Ltd. was listed on the SME Board of the Shenzhen Stock Exchange and became the first American-funded enterprise to visit the Shenzhen Stock Exchange; Guangdong Anjubao Digital Technology Co., Ltd. landed. The Shenzhen Stock Exchange's Growth Enterprise Board became the first listed company in the domestic building intercom industry. In addition, Shenzhen Jieshun Technology and Diwei Video are also coming soon. Listed companies have obtained considerable funds through financing in the capital market. For example, Hikvision raised more than 30 billion yuan, and fewer companies also received several hundred million, which provides strategic planning and scale expansion for enterprises. A very adequate financial support has also greatly enhanced the market competitiveness of enterprises.
In the past two years, listed companies in the security industry, Hikvision's listing is undoubtedly the most market concern. Through listing, Hikvision raised a total of 3.338 billion yuan of funds to shareholders of listed companies. Abundant funds have created a relaxed development space for Hikvision's strategic planning. Hikvision regards the overseas market as the main development direction of the company's future strategy. Based on the current wholly-owned overseas subsidiaries of Hong Kong and the United States, the European Dutch subsidiary and the Indian holding subsidiary, the company has passed the emerging rules that the market rules are still immature. In the economy, joint ventures and cooperation with local companies are set up to establish holding subsidiaries, and wholly-owned overseas subsidiaries are established in mature markets with mature market rules to complete the layout and landing of global sales networks in 2-3 years, and to achieve markets. Localization and no-time difference plans for promotion and sales support.
Third, the national strategy of the Internet of Things, the biggest winner is the three levels of the security of the Internet of Things is the perception layer, the network layer to the application layer. From the perspective of the security industry, it includes video surveillance, burglar alarms, access control management, fire warning and security services, and command and control. In these areas, security products and technologies are already very independent and mature. Application is an important part of the Internet of Things. For example, the camera in video surveillance is an image sensor, which plays a role in perception and is a typical Internet of Things application. With video surveillance cameras as sensing and acquisition front-ends, security video surveillance systems throughout the country have woven into a network. The digitized and intelligent development of the video surveillance system will further enrich the content of the Internet of Things in security applications.
In other areas of application, security technology products together with RFID and wireless sensor technologies have jointly built a more complete and three-dimensional application system. For example, intelligent transportation, perimeter prevention, smart homes, and more complex industrial applications.
Fourth, security The Twelfth Five-Year Plan guides the development of the security industry in the next five years 2011, which is the beginning of China's Twelfth Five-Year Plan. China's security industry authorities organized and organized the preparation of the “Twelfth Five-Year Plan for Development of China's Security Industry†(2011-2015). The Security Twelfth Five-Year Plan will undoubtedly guide the development direction of our security industry in the next five years. The draft of the 12th Five-Year Security Plan proposed that during the 12th Five-Year Plan period, the development goal of China's security industry is to double the industrial scale by the end of the “Twelfth Five-Year Plan†period. The annual growth rate is about 20%. In 2015, the total output value reached 500 billion yuan, and the added value was 160 billion yuan. The annual export delivery value reached 60 billion yuan or more. Industrial restructuring has achieved initial success. The proportion of security operations and various service industries has reached more than 20%.
The draft proposes that during the 12th Five-Year Plan period, China’s security industry will, in accordance with the requirements of strategic emerging industries, continue to enlarge and strengthen the scale of the industry, at the same time promote the adjustment and upgrade of the security industry structure, further transform the growth mode, and promote the development of industrial intensification. . Rationally guide the industrial layout and actively play the role of industrial agglomeration. In addition to continuing to foster the Pearl River Delta, Yangtze River Delta and Bohai Rim three major security industry clusters, supporting part of the processing and manufacturing and R & D business to transfer to the central and western regions, guiding the Chengdu-Chongqing Economic Zone, Wuhan city circle and other security industry groups to the direction of specialization. development of. Encourage and support conditional enterprises to adhere to export-oriented development strategies and develop international markets. We will gradually reduce the exports of simple OEM and resource-based low-end products, increase the export business of products with high added value and proprietary intellectual property rights, encourage integrated and service companies to go abroad, and actively explore new modes of international business.
The development of the security industry is still relying on the key needs of the domestic security market, comprehensively broadening the field of security applications, and improving the status and role of security in public social security services; focusing on entering the international market and expanding the share of domestic security products in the international market .
Four Drivers of China's Security Industry Development in 2011
In recent years, China's security companies are constantly accelerating the pace of new product development, production, and mass production, and the market presents a scene of both supply and demand. From the perspective of the overall performance and industry development trend of China's security enterprises in 2011, the driving forces from the industry itself to promote the sustainable development of the security industry are mainly reflected in four areas: the explosive growth of high-definition monitoring, the intensification of the capitalization of security companies, and the national strategy of the Internet of Things. The 12th Five-Year Plan for Safeguarding and Safeguarding Security has led to an increase in the tilt of the industrial policy toward the security industry and the increasing degree of attention and support from local governments to local security companies.
