With the rapid development of China's security market in recent years, the security chip market has also experienced strong development. The needs of the security industry have gradually become clear, and chip manufacturers have begun to pay attention and take the initiative to promote security, a market with huge potential. The development of the security industry has attracted more and more chip manufacturers to join and become a new profit focus point after industrial automation, consumer electronics and other fields. However, in the era of China's lack of core chip technology with self-owned property rights, the localization and industrialization of security chips have also become a constraint for Chinese security companies to seize technological heights.
At present, domestic production resources are very abundant. At the same time, industrialization, standardization, and the involvement of third parties provide the chip design industry with the possibility of rapid market entry, thus promoting the gradual upgrading of localization and industrialization of chips. The vigorous development of the security industry has made domestic chip manufacturers see hopes. A group of companies dedicated to R&D production of domestic chips, such as Hass, Zhongxingwei, Shanghai Fushen and Hangzhou Jingtu, will focus on security chips and try to In the security industry to flex its muscles and maximize its value.
After more than 30 years of development, China's security industry has grown into a new industry in the national economy that has begun to take shape, has a complete product range, a wide range of applications, and a high level of technology. In particular, since the launch of the safe city construction in 2004, with the intensified implementation of the strategy of strengthening science and technology and the increase in people’s living standards, the demand for the civil security market has increased, together with the Beijing Olympics, the Shanghai World Expo, the Guangzhou Asian Games and other large projects. The security requirements have provided an opportunity for the rapid development of China's security industry.
According to data from the survey, the total size of China's security market in 2009 was about 180 billion yuan. In 2010, the total market size reached 230 billion yuan, an increase of over 23% compared with 2009. Among them, in the total scale of RMB 230 billion, the output value of security products was approximately RMB 105.0 billion, accounting for approximately 46% of the total. According to the "12th Five-Year Development Plan for China's security industry," the total industrial output value in 2015 will reach 500 billion yuan. According to the compound annual growth rate of 20% in the whole industry, the output value of the video surveillance system will exceed 100 billion yuan, accounting for more than 50% of the security electronic system, and become the largest segment with the most growth potential. The increasing demand for video surveillance market, in addition to causing concern of security monitoring equipment manufacturers, also caused widespread concern for the chip manufacturer, the core device of video surveillance.
With the rapid development of China's security market in recent years, the security chip market has also experienced strong development. The needs of the security industry have gradually become clear, and chip manufacturers have begun to pay attention and take the initiative to promote security, a market with huge potential. The development of the security industry has attracted more and more chip manufacturers to join and become a new profit focus point after industrial automation, consumer electronics and other fields.
However, in the era of China's lack of core chip technology with self-owned property rights, the localization and industrialization of security chips have also become a constraint for Chinese security companies to seize technological heights.
The Status of China's Chip Industry For many years, the chip has been restricting the development of China's electronics industry. To overcome this bottleneck, many generations have made unremitting efforts to get rid of the "foreign chip" constraints. After more than 30 years of hard work, the Chinese people finally saw the dawn of the national chip industry. According to statistics, there are as many as 1,188 chip companies registered in "China Manufacturing Network." The growth rate of Chinese chip companies is also alarming. Once in a day, four new chip companies were registered. It can be said that China has launched a "chip business boom." According to statistics, there are nearly 1,000 "chip design" companies that specially design chips and employ about 20 to 50 people.
At present, China's IC industry has developed rapidly. During the “Eleventh Five-Year Plan†period, China’s integrated circuit production increased from 26.11 billion to 65.3 billion, with an average annual growth rate of 20.1%. Sales revenue increased from 70.21 billion yuan to 144.02 billion yuan, an average annual growth rate of 15.4%. Among them, the chip manufacturing industry grew from 23.29 billion yuan to 44.71 billion yuan, an average annual growth rate of 14%. Ms. Wang Qinsheng, director of IC Design Branch of China Semiconductor Industry Association, pointed out that from the perspective of the design industry, it is divided into three industrial bases in the Yangtze River Delta, the Pearl River Delta, and the Beijing-Tianjin region, and each has its own strengths. Among them, the Yangtze River Delta region is the region with the most abundant and complete production chain, and has been developing rapidly in the past two years. The Pearl River Delta region is the frontier of applications and markets, and is the region where Chinese industries are in line with international standards. The advantages of the Beijing-Tianjin region are: Many scientific research talents and strong design capabilities. At present, Pudong has become the main force of the chip industry in mainland China. The leap-forward development of Pudong's chip industry has increased the manufacturing level of Chinese chips and enabled domestic related industries to initially have the ability to compete with other companies in the world.
Regarding the development prospects of China's chip industry, the “Decision to Accelerate the Cultivation and Development of Strategic Emerging Industries†announced by the State Council at the end of last year clearly defined the chip industry as a core basic industry. This year marks the beginning of the implementation of the national "Twelfth Five-Year Plan". How to insist on the application of the whole machine as the traction, and take the market as the guide, focuses on promoting technological innovation, mastering core technologies, developing superior products, forming innovative features, and adjusting product structure, Cultivating and forming enterprises with international competitiveness and realizing the rapid development of industrial groups has become the direction of future development of the chip industry.
Security chip foreign brands dominated At present, the security chip industry located in the upper reaches of the security industry chain is basically controlled by foreign companies; hardware equipment manufacturers in the middle reaches of the industry chain have a certain degree of research and development technology, in some areas have also occupied a higher The market share; while the system integration industry downstream of the industry chain is still in the initial stage of development, the market is relatively decentralized. Chips and key devices used in the security field are basically imported from abroad, which has become a bottleneck restricting the further development of the industry. Due to the lack of core technology, many companies only earn processing or assembly fees for their products, earning only one-fifth to one-tenth of profits from upstream technology companies.
After years of development, China's security companies have greatly improved their product quality and technological content, and they have a clear competitive advantage in the domestic and international low-end product markets. The strong market demand also provides favorable conditions for the development of security chips. Security chips are likely to become another new area of ​​concern for IC design companies. A large number of international semiconductor companies such as TI, NXP, ADI, Techwell, and Nextchip have set their sights on China's security market. Tailoring some chips that meet China's security market has played a positive role in promoting the vigorous development of China's security market.
In 1999, NXP (formerly Philips) PNX1300 chip was promoted and applied in China's security market, becoming the first chip dedicated to the security industry. In 2003, TI launched the universal digital media processor TMS320DM642, which unveiled its formal entry into the digital video surveillance field in China. Subsequently, TI successively introduced several chips for video compression codec such as the DM644x, DM3xx, DM646x, and DM648. This laid the TI's "dominant" status in security video surveillance.
The emergence of China's "security core" from the technical point of view, the security application system has been clearly divided into front-end, management platform, communications, exchange, storage management, etc., also produced a lot of business applications combined with the management platform. Prof. Chen Long, a researcher at the Institute of Automation of the Chinese Academy of Sciences, said that at present, engineering companies, equipment manufacturers, integrators, and engineering companies are at a game stage. It is unclear who will play a leading role in the industry in the future, but it is networked, intelligent, IT, and security. Integration and application will be the main direction for the future development of the security industry. This integration will not only broaden the development of the industry, but will also change and improve the various products in the industry chain and promote the industry to achieve better development. With the continuous improvement of domestic chip technology, pure localization in the security industry chain will also be realized.
Users need to see more clearly, save more, use more convenient, expand the application from islands in the past to horizontal and vertical networking, system capacity rises sharply, and security moves toward digital, network, and intelligent. The security, technology and product and system form have undergone changes. Whoever has the ability to independently research and develop and master the advantages of core technologies will be able to become the leader in the transformation. As the core link in the security industry chain, chip technology has also become a market that Chinese chip manufacturers compete for.
At present, domestic production resources are very abundant. At the same time, industrialization, standardization, and the involvement of third parties provide the chip design industry with the possibility of rapid market entry, thus promoting the gradual upgrading of localization and industrialization of chips. The vigorous development of the security industry has made domestic chip manufacturers see hopes. A group of companies dedicated to R&D production of domestic chips, such as Hass, Zhongxingwei, Shanghai Fushen and Hangzhou Jingtu, will focus on security chips and try to In the security industry to flex its muscles and maximize its value.
Among them, Hass is the main supplier of video surveillance chip, providing video surveillance SoC chip solutions, which account for about 70% of domestic DVR products. And, in Taiwan and South Korea, it has become the main supplier of video surveillance chips. Fuhan's main push is pure codec (CODEC), which has already been shipped on Haikang hard-pressed cards. Hangzhou Jingtu also does codec (CODEC), which is mainly used by Dahua. Prior to China Star Micro, MPEG4 video compression chip with VGA resolution was introduced, and later it took the opportunity of the SVAC standard to promulgate its leading position in chip core technology.
Shenzhen Raystar Semiconductor Co., Ltd. Rayong told reporters that as a chip design company, Hass consider more to provide a flexible and easy to use development platform. Based on the booming surveillance situation in the country, Hass since 2006 launched the world's first H for security applications. The 264 SoC chip has begun and it has been developed to the third generation of SoC chips. It has become a leading provider of video surveillance solutions in China. In 2011, Hass introduced five chips Hi3531, Hi3532 and Hi3507, Hi3516 and Hi3517 for DVR and IP cameras.
In June last year, China Star Microelectronics released the VC0358 series of multimedia image processing chipsets for security surveillance industry. It adopts a multi-core heterogeneous low-power multimedia processor architecture technology and is a DSP chip widely used in next-generation IP video surveillance cameras. Zhongxingwei Chairman Deng Zhonghan stated that ChinaStar Micro chose digital multimedia chips as its breakthrough point and vigorously explored new areas. At present, it has begun to enter the digital multimedia chip market of video surveillance products. In addition, Vimicro has successfully participated in the development of the national standard for security monitoring, SVAC, which has laid a good position for Vimicro's leadership in chip core technology.
Fu Hao Microelectronics released by Shanghai Fuhao Microelectronics FH8735/FH8736 Series H. 264 video coding chips provide product solutions for multi-channel high-definition DVR boards, embedded DVRs, video servers, and high-definition network camera applications.
The promulgation of the SVAC standard enhances the status of China's "core" For a long time, China's security products lacked the "Chinese core" and were subject to restrictions imposed by foreign chip makers. As the industry's first audio and video codec technology standard with independent property rights, the impact of SVAC is far-reaching. The national security chip industry, which has always been in a weak position, has introduced new vitality, and it has also maintained a good impetus for the development of national brands. As one of the units involved in the formulation of the SAVC standard, China Star Microelectronics released a digital multimedia chip supporting national standard SVAC. In addition to its core multi-core heterogeneous low-power multimedia processor architecture technology, scene-based high-fidelity images are used in the front-end image processing section. The image acquisition and imaging processing in the processing technology enables to record as much image information as possible in a wide dynamic range scene and obtain a clear image restoration visual effect, accurately reflecting a real-world scene.
With the increasing maturity and continuous development of these digital video systems, a series of corresponding audio and video coding standards for digital video surveillance are rapidly developed and continuously improved. From MPEG-1 to MPEG-4 to H. 264, China has not had its own security video surveillance digital audio and video encoding and decoding standards. The promulgation of the SVAC standard has solved the practical problems faced by surveillance video and audio coding, and it is in line with China's security monitoring and application requirements, and has the video and audio codec standards of China's independent intellectual property rights. The development of the SVAC standard is conducive to achieving a breakthrough in international security standards in the field of security.
The SVAC standard is the basic technology for digital, high-definition, and intelligent security. The core of the SVAC standard is that it not only addresses the actual needs of monitoring, solving the practical problems faced by the monitoring of audio and video coding; but also faithful to the audio and video encoding of the scene. Under the premise of guaranteeing the quality of audio and video, SVAC standard can provide high coding efficiency; under the premise of equal performance, the specific algorithm preferentially adopts a scheme with domestic independent intellectual property rights, and has a flexible and extensible architecture.
Chen Chaowu, deputy director of the Ministry of Public Security, stated that SVAC, as the basic standard for video surveillance systems, will provide strong technical support for the construction of urban public security comprehensive prevention and control system. On the one hand, it can solve the current audio and video codec in video surveillance systems. The inconsistency of the standard leads to the system's difficulty in interconnecting and interoperability. On the other hand, it can propose appropriate solutions for security and special applications, and solve the problem that the current video surveillance field can only adopt the standard of radio and television and cannot meet the special needs of security.
Faced with high-definition demand, China's "security core" should be moved from time to time. The rapid development of the digital video surveillance market has brought new development opportunities to chip suppliers. In terms of digital signal processing, analog power supply, and monitoring platforms, major chip suppliers have stepped up research and development and have introduced new products to seize market opportunities. According to statistics, the cost of a digital network HD camera with a resolution of more than 720p a few years ago was 7,000 yuan per unit. With the maturity of compression technologies such as Hass, TI, and ADI, the cost of the chip has been declining. The cost of HD network cameras began to fall dramatically. From the point of view of clarity, 1080p has already entered the practical stage.
Zheng Xiaolong, DSP business development manager at Texas Instruments, told reporters that TI’s new single-chip architecture for network cameras supports 1080P@60 video compression capacity equivalent to four million HDs this year, and the main processor is the Cortex A8. Frequency up to 1GHz, front-end enhanced ISP, can capture high-definition video directly. Internally, the industry-popular C674x universal DSP core is also integrated, enabling various advanced intelligent video analytics to be brought to a new level in the application of network cameras. In addition, TI's megapixel camera core platform, TMS320DM365, is widely popular in the market. The SoC integrates a reliable but powerful ISP that can support a wide range of megapixel CMOS video sensors including Aptina, OVT and Sony.
In the face of a flourishing high-definition surveillance market, chip makers should be on the move. According to Liu Xing, director of marketing monitoring for HiSilicon's line of product lines, from Hass's point of view, to achieve high-definition video surveillance, full HD must be realized from front-end video capture to background playback, storage, and management. Hass invested relatively late in the IP Camera and began to work hard in 2011. This year it released Hi35107, Hi3516, and Hi3517 high-definition IP Camera chips. With Hi3531, Hi3532 high-definition DVR/NVR solutions, it will provide full HD system solutions.
It is understood that the Hi3531/Hi3532HD DVR single chip's encoding capability has been upgraded to 4 channels of 1080p@30fps H. 264. Hi3531 provides dedicated intelligent acceleration engine and dedicated network acceleration engine to relieve CPU pressure for high-definition computing. Combined with the latest ARM Cotex A9 dual-core CPU, a more brilliant user interface and rich smart applications will become possible. For the IP Camera series, the Hi3507 (up to 720P@30fps) can be docked with a CCD headend and a CMOS Image Sensor with ISP. Its proven and stable solution will accelerate time to market; H i 3 5 1 6 (up to 1080p @50fps) is a 1080p@30 frame 5-stream SoC chip designed for IP Camera. From the technical point of view, intelligent video analysis is divided into two processes of information collection/separation and data processing. In the future, Hass considers that the intelligent monitoring algorithm information collection/separation part can be completed on the chip, reducing the threshold for the development of intelligent monitoring technology.
Conclusion Continual introduction of new technologies, new products, and new services in the security industry has accelerated the application and popularization of these products, resulting in a large number of new demands and greatly expanding the development space for the security chip industry.
The technological evolution path of China's security chips is also becoming clearer, and the trend of functional diversification is becoming increasingly apparent. With "China Core", on the one hand, all chip product definitions really come from domestic customers, system integrators, and end-users in the industry, ensuring that the chips truly meet customer needs at the source. On the other hand, it closely follows the evolution of domestic customers' products in the chip layout and promotes the continuous upgrading of the video surveillance industry from CIF to D1 to Full HD. After more and more "China Core", it will reduce the access threshold for the security industry, so that more and more manufacturers can participate in the development and production of video surveillance equipment. In addition, the use of a drop in the threshold makes video surveillance equipment not only confined to such sectors as banking, transportation, and safe city users, but will also lead to the rapid development of the civilian market, which will make the security monitoring industry bigger and bigger, and the market prospects considerable.
At present, domestic production resources are very abundant. At the same time, industrialization, standardization, and the involvement of third parties provide the chip design industry with the possibility of rapid market entry, thus promoting the gradual upgrading of localization and industrialization of chips. The vigorous development of the security industry has made domestic chip manufacturers see hopes. A group of companies dedicated to R&D production of domestic chips, such as Hass, Zhongxingwei, Shanghai Fushen and Hangzhou Jingtu, will focus on security chips and try to In the security industry to flex its muscles and maximize its value.

Frequency up to 1GHz, front-end enhanced ISP, can capture high-definition video directly. Internally, the industry-popular C674x universal DSP core is also integrated, enabling various advanced intelligent video analytics to be brought to a new level in the application of network cameras. In addition, TI's megapixel camera core platform, TMS320DM365, is widely popular in the market. The SoC integrates a reliable but powerful ISP that can support a wide range of megapixel CMOS video sensors including Aptina, OVT and Sony.
In the face of a flourishing high-definition surveillance market, chip makers should be on the move. According to Liu Xing, director of marketing monitoring for HiSilicon's line of product lines, from Hass's point of view, to achieve high-definition video surveillance, full HD must be realized from front-end video capture to background playback, storage, and management. Hass invested relatively late in the IP Camera and began to work hard in 2011. This year it released Hi35107, Hi3516, and Hi3517 high-definition IP Camera chips. With Hi3531, Hi3532 high-definition DVR/NVR solutions, it will provide full HD system solutions.
It is understood that the Hi3531/Hi3532HD DVR single chip's encoding capability has been upgraded to 4 channels of 1080p@30fps H. 264. Hi3531 provides dedicated intelligent acceleration engine and dedicated network acceleration engine to relieve CPU pressure for high-definition computing. Combined with the latest ARM Cotex A9 dual-core CPU, a more brilliant user interface and rich smart applications will become possible. For the IP Camera series, the Hi3507 (up to 720P@30fps) can be docked with a CCD headend and a CMOS Image Sensor with ISP. Its proven and stable solution will accelerate time to market; H i 3 5 1 6 (up to 1080p @50fps) is a 1080p@30 frame 5-stream SoC chip designed for IP Camera. From the technical point of view, intelligent video analysis is divided into two processes of information collection/separation and data processing. In the future, Hass considers that the intelligent monitoring algorithm information collection/separation part can be completed on the chip, reducing the threshold for the development of intelligent monitoring technology.
Conclusion Continual introduction of new technologies, new products, and new services in the security industry has accelerated the application and popularization of these products, resulting in a large number of new demands and greatly expanding the development space for the security chip industry.
The technological evolution path of China's security chips is also becoming clearer, and the trend of functional diversification is becoming increasingly apparent. With "China Core", on the one hand, all chip product definitions really come from domestic customers, system integrators, and end-users in the industry, ensuring that the chips truly meet customer needs at the source. On the other hand, it closely follows the evolution of domestic customers' products in the chip layout and promotes the continuous upgrading of the video surveillance industry from CIF to D1 to Full HD. After more and more "China Core", it will reduce the access threshold for the security industry, so that more and more manufacturers can participate in the development and production of video surveillance equipment. In addition, the use of a drop in the threshold makes video surveillance equipment not only confined to such sectors as banking, transportation, and safe city users, but will also lead to the rapid development of the civilian market, which will make the security monitoring industry bigger and bigger, and the market prospects considerable.
