Let us see more clearly — explore high-definition video surveillance (1)

In 2008, for the security industry, is a year of rapid development, city of modernization and rapid economic development, building a harmonious society, the city of industry system security monitoring work presents many new demands and issues.

At the same time, safe city project, Olympics, all for the security industry for the development of a broad platform for the industry in technology development. The security industry in occupies a very important position at video monitoring products, rapid development in the security market, while exposing a lot of problems.

With video monitoring technology for high-speed development, customer for video surveillance product requirements are rising, the functional requirements of a more perfect, stability, and performance requirements of clarity and accuracy.

At the same time, shopping malls, Office, monitoring sites how to see a person's facial features and how do I see high speed vehicle licence? crowded noisy train station, stadiums, squares, etc, how to quickly and accurately find target ...? These are video monitoring product need to be addressed.

Panoramic view of the current video surveillance product market can be said to be a clash of the era, and many research and development strength, a high market share.

But their product development to a certain stage, now have access to a bottleneck. A very important performance is the market for video surveillance product homogeneity, lack of people "eyes bright" products. Motion detection, dual stream, network storage, 16-channel full D1 products that are in one or two years ago still very advanced technology, and now almost all products can be realized. Product homogeneity has one problem is that in many projects, products, competition has evolved into a simple price competition, have serious extrusion manufacturers, engineering business profit.

Video monitoring products in the digital, a network of two important stage of development, video surveillance product development?

High-definition demand highlights

"Let us see more clearly", this is the number of users in the use of digital video monitoring products made of a very urgent needs.

United States authority IT market research company MultiMedia Intelligence President Mark kirstein refers to the promotion of video surveillance equipment market development of four technical factors: million pixel camera, high-performance codec, powerful analysis technology, as well as easy from closed-circuit television (CCTV) migrated to IP/network video monitoring of all underlying technology. From his words, we can see, the four technical factors in the million pixel camera, high-performance decoder, and IP network technologies, and high-definition products, represents the high-definition products collection, coding, network transmission development direction.

Hikvision as video monitoring products of major vendors, they feel "high definition" of this trend.

In the past two years, hikvision full D1 high definition codec decoding products throughout the product system share in the rapidly expanding. In hikvision participation of many large projects, such as Shanghai six Summit, Germany World Cup and the 2008 Beijing Olympic Games, the world's attention, many important places of the monitor have all used hikvision most high-end full D1 DVR, and video server products. And financial, education, safe city and other key items on the clarity of the video surveillance products also put forward higher requirements.

What is high definition?

What is HDTV? in recent years more and more manufacturers to launch the "high definition" of products.

And monitoring industry inside some unwritten understanding for HD. For example, many occasions we speak of high definition products, in fact, the resolution can reach D1 or 4CIF products. Then, the video surveillance industry, the concept of "high definition"? what is the real "HD"?

We look for high-definition digital television technology.

The main points HDTV standard definition television and high definition TV. Standard definition TV (SDTV) refers to the image quality equivalent to the current conventional analog TV system with digital TV systems such as PAL, clarity about 500 TV lines, the rate of about 5Mbps; high-definition television (HDTV) refers to the level of sharpness and clarity about the current vertical analog TV system doubles as the aspect ratio of 16: 9 TV system, definition of about 800 TV lines or more, the rate of about 20Mbps.
