Million HD monitoring heat expands the potential of princes for hegemony

As 2010 is about to pass, we can look back at the exhibitions across the country and even around the world. People can clearly feel that the industry's enthusiasm for the "million-high-definition" is soaring. It can even be said to be passionate. This is not surprising, although in the early years it also caused "high-definition fever", but after all, the timing did not arrive, and the thunder and rain were small. At the moment, everyone is aware that high-definition surveillance is already within easy reach. In the face of such a difficult industry change, the security professionals in the security industry are not yet ready to do anything and try to compete for dominance.

Millions of high-definition video has already hit the video surveillance market with torrents, and even shakes the entire security industry. The more in this transformation, the more colleagues in the industry need to respond wisely to the market, face the users, and understand what kind of "high definition" we really need.

If you choose only the right ones, you will not blindly pursue high-pixel surveillance instead of the highest-level HD surveillance. You must pay more attention to the practicality of products and technologies. Rational choice is justified, and it should have been the slogan: Choose only the right one, not the expensive one. We need high-definition pixels is not the higher the better?

Currently, there are two types of resolutions, 1080P and 720P, which are popular on the market. Let's compare them first. As there is no uniform standard for high-definition in the security industry, from the perspective of the field of broadcasting and television, 720P is a format standard for high-level HD digital television developed by the United States Film and Television Engineers (SMPTE), and it is a D4 standard digital television display mode. The effective display format is 1280×720; 1080P is the D5 standard digital television display mode, which is generally 1920×1080.

Technically speaking, 1080P and 720P use a progressive scan method. The actual scan lines for each frame of image are 1080 lines and 720 lines. The progressive scan method can solve the flicker phenomenon caused by interlace scanning, and it can provide a clearer and more stable image cage-face. The most suitable human eye vision standard for progressive scan is 75 images per second, but in security monitoring, 30 images per second can already meet user requirements.

From the perspective of market applications, the 720P and 1080P markets are obviously not on the same plane. 1080P needs 23, 24 inch or above LCD screen to be able to watch from point to point, CPU frequency is probably more than 3G, or there is hardware decoding graphics card, aiming at high-end consumers, need product excellence. The 720P market faces a large number of ordinary consumers. In addition to the difference in the application of positioning, the two also have a big difference in price. Take consumer digital DV as an example, the price difference between 720P and 1080P is more than 1,000 yuan. For security monitoring, product features and performance are focused on "use," and users do not need to "play" cool, nor do they pay for unnecessary features.

From the ultimate goal of security monitoring, a video that is clearly visible is a valuable video for us. On the one hand, consumer electronics products stimulate security surveillance to quickly enter the high-definition era; on the other hand, it is easy for people to regard consumer video as a goal, thinking that high-definition surveillance, the higher the pixel, the better.

Although in the field of broadcasting and television, 720P has begun to show decline, but in the field of security, it can be said that the prologue of the 720P era has just been opened, with the increasing popularity of millions of high-definition monitoring, 720P will become the mainstream representative of the future industry standards, it and 1080P There is competition among them, but more is a complementary relationship. The diagnosis formed by this situation is mainly based on equipment costs and the pressure of transmission and storage links.

High-definition, a set of integrated solutions High-definition monitoring brings new challenges to video encoding, transmission, and storage systems, because their industry standards have not yet been unified. Therefore, one million HD surveillance is a system solution, and all links must support high-definition, rather than buying a camera with millions, millions or even tens of millions of pixels.

Therefore, at the exhibition and in the media, users should not be easily impressed by high-definition manufacturers' eye-catching titles and exciting advertising slogans. They are blindly pursuing high-resolution pixels driven by “emotions”. As a result, they are extravagant in the front-end, but ignore the back-end. The end of the game. It is like buying a high-grade suit. When you look in the mirror, you find that you wear double-sneakers on your feet. If you want to match, you have to continue to “blood the blood.” In the end, it is not a cocktail party but a fellow party.

A complete set of high-definition solutions, to cover video capture, encoding, transmission, storage, control, decoding output until the center management platform. The realization of high-definition video capture is only the first step to complete the high-definition monitoring system. The next step is to perform high-definition encoding and transmission of high-definition code streams, exchange control of high-definition digital signals, and high-definition codestream access and high-definition display. Especially in the current situation where the HD network camera industry standard is not yet uniform, this puts very high demands on millions of HD manufacturers and sets a high threshold for the millions of HD market.

At present, after few years of painstaking research, few domestic excellent security companies have already had their own core technologies in the field of millions of high-definition surveillance technology, launched a complete high-definition intelligent monitoring product and overall solution, and successfully applied in some major projects. . As a professional and leading provider of millions of high-definition surveillance products and total solution providers, Wavelite already has a full range of front-end cameras including bolts, infrared cameras, domes, and domes, with low illumination, wide dynamics, and 3D intelligence. Noise reduction and other functions are complete, and a full set of back-end equipment such as digital hard disk recorders, high-definition decoders, optical fiber transceivers, and millions of high-definition system cards are also developed. In addition, Wave and Particle has an independently developed one-piece movement.

In addition to focusing on the improvement of the definition, the high-definition monitoring system also needs to combine the application requirements of different industries, and launch a personalized customized solution, so that high-definition technology can fully serve the actual combat. For example, for traffic monitoring, there are high-definition bayonet systems dedicated to bayonet monitoring, high-definition license plate recognition systems, etc. These systems implement high-definition image acquisition and analysis applications in a number of specific sectors such as capture, panoramic video recording, and license plate recognition. Let the public security department detect cases to become efficient, intelligent and convenient.

In short, during the ups and downs of the industry, people tend to be sensible and ignore the maintenance of reason. If the competition is focused on the resolution, it will lead to homogenization of HD surveillance at the front end, misleading consumers, and thus wasting social resources. At this time, whether it is the industry's manufacturers, distributors, engineering companies or end users, we must maintain rationality, according to actual needs to select products in order to truly enjoy high-definition monitoring.
