High-definition surveillance integrated movement competition intense survival of the fittest

After Hitachi introduced the first truly high-definition movement product in 2010, many movement manufacturers also saw the development of the domestic security industry in the direction of high-definition, while the demand for high-definition movement products accounted for an important market share. Huge business opportunities, have launched the corresponding high-definition movement products, the market is fierce competition. When Hitachi launched the 1.3-megapixel high-definition movement DI-SC110-C in 2010, Sony and Samsung launched 2 million CMOS high-definition movements to gain market share. Subsequently, LG's LNM1220 12x zoom full HD 1080P and LNM2810 28x zoom 720P HD machine movement, Panasonic 4 million pixel GP-MH310 HD one machine movement has also been available. However, Hitachi did not show weakness. In mid-2011, Hitachi’s DI-SC220-C 1080P Full HD All-in-One caliber movement was also born. It is reported that this year Hitachi will launch a new 720P high-definition movement, although Pixels did not perform much, but this product is the world's first truly high-definition movement with a fog-fighting function, and its performance in low-light conditions has also been a qualitative leap compared to previous products. So it seems that in the field of high-definition movements, the fierce competition of foreign manufacturers is not tragic.

Although Japanese and Korean companies have certain advantages in high-definition movement technology innovation compared with domestic enterprises, from the 2011 CPSE Expo and the security exhibitions in the first half of the year, domestic companies exhibited HD high-tech one-piece movement products. In terms of technical performance or design, it is not inferior to foreign manufacturers, but also some excellent HD movement manufacturers. For the status quo of domestic high-definition movement manufacturers, Zhong Wei, product manager of Zhejiang Dahua Technology Co., Ltd. stated: "For domestic manufacturers, sensors and lenses are selected from other homes, and will focus on image processing, autofocus algorithm research To improve their core competitiveness."

For example, in the year 2011, Wave Particle launched its own BL-1080DC, which is one of the few million high-definition all-in-one camera manufacturers in China, breaking the monopoly of foreign high-definition video surveillance technology. The high-definition movement boasts 2 million pixels, a minimum illumination of 0.01 Lux, a 36x optical zoom, and day and night double filter automatic conversion. It has exceptional performance in low illumination, high definition, and remote monitoring. It also has good performance with low energy consumption and low calorific value. After the launch of BL-1080DC, it received a great deal of attention, which had a great impact on foreign companies.

Dahua’s 2 million 20-times ICR day and night HD camera DH-CA-HZ2020 is also quite representative. The device uses a high-reliability, high-performance industrial FPGA chip as image acquisition, processing and control chip, the maximum effective pixel up to 2.4 million, the optical imaging, image acquisition, image processing, automatic white balance, automatic exposure, automatic Focus, zoom control design as a whole, high reliability, image color reproduction ability and can automatically adapt to different color temperature, different illumination, different object distance shooting environment, image output and control signals use LVDS interface to open to the outside, back-end use wiring Convenient, high reliability of signal transmission, reliable operation in all-weather all year round in the range of -20°C～+60°C.

There are Jingyang's SN-CMD7100DN/Z18 megapixel high-definition one machine movement, which is equipped with an 18x high-performance optical zoom lens, combined with Jingyang's own research and development of high-precision image focusing algorithm, the zoom speed is extremely fast It not only provides the ideal surveillance field of view, but also enables perfect autofocus.

In addition, Aipu Vision, Haoyu, Tomorrow Industrial, Shenzhen Jiegao, eyewitnesses, etc. are the main force of the domestic high-definition one machine movement manufacturers, their appearance to a foreign high-definition movement manufacturers came to an attack. , Let some well-known foreign high-definition integrated machine movement manufacturers have to pay attention to the domestic security technology update speed and market share. The advantages of foreign manufacturers are in technology, and domestic manufacturers are more cost-effective. In today's increasingly fierce competition in the domestic security industry, the principle of “natural selection and survival of the fittest” also applies. It is not the high-priced product that is the preferred choice. it's the best.

From the perspective of many high-definition movement manufacturers at home and abroad to increase the R&D and marketing of high-definition all-in-one machine movements, it shows that the spring of high-definition movement products has come, and its market performance also appears to be “vital”. Although the competition is extremely fierce, but both domestic and foreign manufacturers need to rationally treat the high-speed growth performance of the current high-definition movement market, rational competition, and maintain a good order of the HD movement market.
