Let us see more clearly – Discovery HD monitoring solution …

Safe City Project, the Olympics are for the security industry for the development of a broad platform for the industry

Technology Development. The security industry plays a very important position in the current video surveillance products, security

Market Rapid development, but also a lot of problems.
With the rapid development of video monitoring technology, customer demand for video surveillance products have also been improved, more complete functional requirements, stability, and performance requirements more clear and accurate. At the same time, in shopping malls and savings and other monitoring sites to see a person's facial features? How to look at a high-speed vehicle license? Noisy crowded railway station, stadiums, squares and so on, how to find the target quickly and accurately ... ...? These are video surveillance product problems to be solved.

Look at the current video surveillance market, can be said from the time a warlords and the emergence of many R & D strength, high market share

Enterprise . But these enterprises to a certain stage of product development, and now have entered a bottleneck period. Performance is a very important market, video surveillance product homogeneity, the absence of people, "eye-catching" product. Motion detection, dual streaming, network storage, 16 full D1 products, which two years ago, or at a very advanced technology, and now almost all of the products can achieve. Product homogeneity is an issue brought in many projects, products, competition has evolved into a simple price competition, a serious pressure on the manufacturers,

Contractors Profit margins. Video surveillance products through the digital, network, two important stages of development, the video monitor where the direction of product development?

HD demand highlights "Let us see more clearly", this is the number of users in the use of digital video surveillance products made in a very urgent need. U.S. IT market research authority

Company Mark Kirstein, president MultiMediaIntelligence referred to promote the development of video surveillance equipment market, the four technical factors: megapixels camera, high performance codecs, powerful analytical techniques, and to facilitate the closed circuit television (CCTV) to migrate to IP / networked video surveillance of all the underlying technology. From his words where we can see, these four technical factors in megapixels camera, high performance codecs and IP network technology, are associated with high-definition products, representing high-definition products in the collection, coding and decoding, network transmission areas direction.

Hikvision As the video surveillance products, major suppliers, have long felt the "HD" this development. In the past two years, full D1 high-definition Hikvision codec codec products in the whole product system share is rapidly expanding. Hikvision participation in many large projects, such as six-nation Shanghai summit, the World Cup and the 2008 global attention

Beijing Olympics , And many important sites to monitor, without exception, the most used Hikvision full D1 high-end hard disk recorders and video servers. And finance, education, safe cities, and other key projects on the clarity of video surveillance products also put forward higher requirements.

What is HD? What is HD? In recent years, more and more manufacturers began to introduce "high definition" of products. And monitoring within the industry there are some unwritten understanding for high-definition. Now many occasions, such as high definition products we are talking about, in fact, up to D1 or 4CIF resolution products. Then, the video surveillance industry, "HD" concept of what? What is the real "HD"?

Have a look at high-definition digital TV technology on the definition.
The main points digital TV standard-definition TV and high-definition television. Standard-definition television (SDTV) refers to the image quality equivalent to the current conventional analog color television system, digital television systems such as PAL, is about 500 TV lines resolution, bit rate of about 5Mbps; high-definition television (HDTV) refers to horizontal resolution and vertical resolution is about the current analog color television system twice a 16:9 aspect ratio digital television system, definition is about more than 800 TV lines, bit rate of about 20Mbps.

ITU Recommendation ITU-RBT.1201 proposed ultra-high-resolution images (HRI) in a number of criteria, the essential element is the smallest image resolution 1920x1080, HRI four levels, including HRI0, HRI1, HRI2 and HRI3, the resolution was 1920x1080, 3840x2160, 5760x3240, 7580x4320.

As defined above, corresponding to the video monitor, using the analog and digital combined surveillance cameras up to standard definition, if by digital processing, the highest resolution up to 4CIF or D1 resolution, about 40 million pixels, resolution between 300 to 500 lines; by HD IP network camera surveillance, to achieve 800 TV lines of resolution, then the network camera's resolution to 1280x720 at least the standard, about 90 million pixels, is the modulus of mixed more than twice the control; the use of a network of 2 million pixel camera, ultra-high definition images to achieve the requirements of the network camera aspect ratio of 16:9, corresponding to a resolution of 1920x1080, aspect ratio of 4:3 in the network camera, corresponding to a resolution of 1600x1200.

Discovery HD monitor Analog products and digital high-definition products than there are many design flaws, making it difficult to present the technical architecture in the resolution, frame rate, etc. have greatly improved. Take clarity, the existing analog CCTV surveillance system, cameras capture the vertical resolution, PAL 625 scanning lines under standard, to 575 after blanking line, the existing ultra-high-definition products has reached 530,540 lines to the basic simulation system to the limit. With the digital system resolution of about 800 lines, compared difference is quite large.

Hikvision very early in the HD field lots of manpower, material resources to new product development and production. In the last year just concluded Beijing 2008 Security show, Hikvision introduced a full range of high-definition video surveillance products and system solutions. In terms of products, Hikvision introduced the industry's highest resolution high-definition IP cameras DS-852MF and DS-862MF, and based on
