In recent years, as the sensor-based front end of the Internet of Things, the sensor is recognized as a promising high-tech industry at home and abroad, attracting worldwide attention due to its high technical content, good economic returns, strong penetration ability and wide market prospect. Under the vigorous promotion of the market of electronic information industry, a certain industrial base has been formed and considerable progress has been made in technological innovation, independent research and development, achievement transformation and competitiveness, which have made important contributions to the promotion of national economic development. Status quo: Market concentration is low At present, there are many small and medium-sized enterprises in the sensitive component and sensor industries in our country and a low market concentration. Compared with developed countries, there are technical gaps, some core technologies and products still need to be imported, and there is an urgent need for localization. Domestic sensor manufacturers to occupy the low-end market From the development trend, the domestic sensor manufacturers have three cases: First, private or joint-venture products occupy the low-end market, the traditional techniques and equipment to meet the vast majority of manufacturing requirements, the market in good condition. In addition to individual manufacturers in individual varieties of chips produced abroad to get the domestic package of related products, accounting for a larger share of the market, other high-end products are monopolized by foreign manufacturers. Second, with the rise of emerging industries such as Internet of Things, the sensor industry has become an important area where all countries in the world contend for the development of new and high technologies. In recent years, China's sensor industry has grown rapidly and its application model has become increasingly mature. However, due to the low grade of the industry and the poor capability of technological innovation, the domestic sensor industry presents a market pattern with low-end surplus and high-end foreign monopoly. Sensor technology has lagged behind the development of domestic strategic new industries smoothly. Foreign-funded enterprises occupy the vast majority of the domestic high-end market share and will continue to dominate the high-end market for a long time to come. Such momentum will not be fundamentally changed in the short term. Third, the development of state-owned enterprises is in a steady state of growth. Generally speaking, the pace of the latest technological developments in foreign countries can not keep up. With the exception of a few manufacturers, the overall gap has been expanding. This is due to the rapid development of sensor technology, faster process and manufacturing equipment updates, and the failure of many domestic manufacturers of new equipment to manufacture them. And the single device price is as small as several hundred thousand dollars, many millions of dollars, the vast majority of manufacturers rely on their own hard to buy new equipment, resulting in many new technologies, new technology can not keep up with the rapid development of foreign companies pace. Development: The general trend of wireless, network terminal battle The composition of the basic operation of the Internet of things is the "sense" of the front end, the "biography" of the middle end and the "count" of the back end. By grasping these three links, this invisible line is clarified. The middle part of the "Biography" also saw some new trends this year, laying the foundation for the integration of the burglar alarm in the large system of Internet of Things. With the gradual application of 3G, WIFI and other means, the trend of wireless alarm products is becoming clearer and clearer. Today, the market application of alarm system, the proportion of wireless products is more and more large, reaching more than 30%. Some traditional wired products to domestic manufacturers, this year also began the introduction of multi-network alarm host, such as Horn's 8003 wireless series, incorporates 3G, GSM, GPRS, CDMA and other communication modules, communication options, greatly enhanced compatibility, installation Easy to use, has won many new and old customers of all ages. Network has become another major direction of alarm products, as closely linked with people's lives alarm products, have also launched a large number of network products. IPC's development has been more mature, this product is compatible with the dual monitoring and alarm protection, and through the INTERNET remote monitoring and storage can be achieved, realize the dream of the world. The development of IPC also makes more end consumers have access to the alarm system. If the alarm companies can take a step further in the alarm platform and information security, the future prospect of IPC is very impressive. In order to comply with the pace of network development, TCP / IP products have become the direction of the alarm system. For example, some IP security host systems introduced by some manufacturers adopt IP technology this year, taking the computer as the main body of operation and sharing the TCP / IP network with other devices, thereby greatly saving the installation cost; and detecting and automatically managing alarm devices by using dedicated software Operating conditions, greatly facilitate the user's management and use. For international well-known alarm brands, wireless and networking have always been the key development directions in recent years. International well-known enterprises generally have gradually increased their communication methods such as TCP / IP, GSM and GPRS, and some also support mobile terminal control. In the civil field, the emphasis on consumers' psychological appeals is also reflected. In 2011, many international products gave people a fresh look and feel. The elements of the application changed the industrial texture of the traditional alarm products and began to take the fashion, Art style. At the same time, the network terminal products require a dazzling appearance and cultural design, the wireless keyboard, remote control has a very high texture requirements. See now some foreign manufacturers launch of the product is very mature, strong system, all with a full set of wireless alarm accessories, products include the host, all kinds of detectors, magnetic door, multi-function remote control, portable remote control, wireless keyboard, wireless alarm, Wireless repeaters, wireless switches and a series of wireless products, truly create a full set of wireless home kits. Technology: the latest scientific research image sensor 2012 CMOS image sensor is favored by the market The important reason is that in the past greatly lower than the CCD sensitivity problems due to the use of new sensor technology, such as back-illuminated CMOS, and gradually resolved. Compared with the CCD sensor, the CMOS sensor has better mass productivity, and it is easy to realize the SoC (SystemonChip) product including other logic circuits, which is very difficult to realize in the CCD chip. CMOS sensors, in particular, do not require a special manufacturing process like CCD chips, so they can directly use production equipment for large-volume products such as DRAMs. As a result, the CMOS image sensor may form a completely different from the cost structure of the CCD image sensor, but also for the highly integrated CMOS sensor has opened up a new direction of development. Early on the market had introduced the CMOS sensor comes with ISP processor, containing 2A (AE, AWB) control algorithm. The development so far, such products are extremely popular and favored by the market. Many small businesses that do not have the ISP image processor / ISP algorithm development capability can use their own 2A-processing CMOS sensors to make HD cameras. Traditional HD camera architecture, from front to back generally divided into several components: the image sensor SENSOR, ISP image sensor, compression / signal conversion processing; and if using an integrated ISP CMOS sensor, the middle part of the FPGA chip to achieve ISP unit can be omitted, so as to effectively reduce the overall BOM cost of the device, but also bypass the ISP algorithm R & D threshold. Currently on the market more affordable 720P HD network camera most of these programs are used.
