HD monitoring system in 2011, volume

Editor's Note: video surveillance is in fact an emerging market, due to the application of industry and customer relatively dispersed, this area of supplier diversity but size is not large.

Over the past several years of development, industry suppliers on digital, HD, and intelligent, rational understanding began to tend to, platform vendors also found applicable technology roadmap.

IP cameras: 2010 is the first

A few years ago, different market research institutions on IP cameras and network video surveillance presents exciting growth forecasts that it will soon be alternative in the market is in the mainstream of analog video monitoring technology.

But today, IP cameras and network video surveillance market still does not scale.

When will the "IP cameras over analog video camera, I now have no way to reply.

"The biggest video surveillance camera vendors — — Hangzhou hikvision digital technology co., Ltd. CEO on the Populus euphratica-China Electronics News reporter said," but we have a consistent view that this is the IP of the domestic market of the year, driving force from megapixel high definition programmes addresses see clearly. Because if you want to see, and now the most effective way is to use IP cameras. This is different with the foreign markets, foreign demand for IP camera is mainly due to the pressure of human construction costs. ”

While in some domestic market segments, IP cameras and network video monitoring growth this year is quite fast.

"We see the application project, whether it is a safe city, or some government projects, mostly need IP network video monitoring. "Shanghai Wei Gan Zhaoguodong told reporters that" in our case, it is estimated that this year's IP network video monitoring of up to 200 percent. ”

This reporter has learned that, in the IP network video monitoring's promotional, Government and industry funding relative abundance of plays the role of the "pioneer".

Texas Instruments video monitoring Department Manager Cyril Clocher said: "according to market research company IMS in traffic and Government industries, nearly 40% of applications with network video monitoring; health and education, network video monitoring of the proportion reached 40%. And together, the next 10 years, IP network camera's CAGR will reach 18%. "At the same time, he also pragmatic view, analog monitor market still. In the market, 4-, 8-and 16-channel D1 30 frames/second product is the industry chain link in the focus of this promotion.

However, in order to seize the upcoming IP network video monitoring development opportunities, and some cities have begun to develop appropriate planning.

Recently, Beijing security industry association is the Beijing city video surveillance industry development strategy, organization of seminars to discuss. Beijing Security Association Secretary Li-Ping on reporters, in the development of strategic vision that Beijing should seize the analog video camera will be replaced by a digital camera, create relevant industrial chain.

HD: impulse 720p next year

HD concept in the video surveillance industry has been hot noisy for many years, but the current application market.

For the application of the effect of high-definition of bottlenecks, hikvision Populus euphratica-CEO of analysis that, above all, technical problems, high-definition of the technical barriers still exist. For example, CCD sensor, power consumption, wide dynamic range CMOS sensor. Secondly, the product price is too high. Once again is the user's understanding and acceptance of a process. "The user to see the successful solutions. "He said," at present, there is little success. It can be compared to water have not boil, so also does not have to ' outs '. "Moreover, he believes that HD has no longer a specific product, but rather a system. With the HD market is gradually taking shape, the standard will be gradually mature market conditions can clarify. "I think the HD market is still in relatively chaotic state. "He said.

Fiberhome communications related persons added that network environment is the hard limit high-definition video surveillance is an important factor in promotion.

"Video surveillance network hosting in general there are three ways. The first is that the 3 g wireless network, the second is the wireless network, the third optical network. "He said," If the transmission of HD video, today's 3 g wireless network does not meet requirements. High-definition video upload needs 2MB bandwidth, but today WCDMA and CDMA2000 upload bandwidth only 600KB to 800KB, TD-SCDMA bandwidth to narrower, but such conditions can only transfer resolution bandwidth low 4-channel D1, CIF or road transport is not yet a high-definition video. "Also, optical networks can only transmit 2-channel high-definition, transmission efficiency is not too high, the relative costs will be more expensive.

To this end, the industry believes that from a pragmatic point of view, high-definition video surveillance will start the product start 720p resolution.

"By 2012, half of the world's IP camera will exceed 720p. "Texas instruments of Mr. Cyril Clocher," then 500 m to 1000 m pixel cameras began to enter the high-end market. ”

This view has been the market's largest CMOS camera company Aptina is responsible for business development in the field of video surveillance of the Cliff, Mr. Cheng.

His analysis to the reporters said: "Although everyone is talking about 1080p high-definition video camera, but I think the programme is consistent with 720p today all qualified elements of technology. Since the cost from the camera, the camera can already 720p and high-end analog camera (VGA) almost, and required network bandwidth is not as high as 1080p. Next year will probably 720p product market momentum before is 1080p. ”

Intelligent analysis: from hype to pragmatic

Intelligence analysis in the last two years in the field of video surveillance as an important direction of development.

Many video supervision enterprises launched facial recognition, vehicle identification, population control and turnFlux flow control solutions. But beginning this year, manufacturers on intelligence analysis technology awareness tends to provide programmes, but also more pragmatic.

"These two years, the industry is indeed for many smart analysis of programme promotion, but the results were not good.

"Haisi semiconductor Beijing sales and technical service department FAE Manager Li Qiang said," because those intelligent analysis techniques are mostly manufacturers selling product of gimmick. "For this reason, this year haisi semiconductor introduces some seemingly simple smart solutions, for example, cordon, retrograde, wandering and other surrounding protection application and brightness exception, video noise, video and video freezing and other missing video Diagnostics programme. Although they look past intelligence analysis capabilities to the "inferior", but more practical.

Texas instruments is responsible for video monitoring of Wang Ning analysis, intelligent analysis is a very deep technology.

Based on the number of statistics, for example, human fat, thin, who is standing for walking or crawling, snow weather and other factors are likely to become some of the statistics, so the noise be accurate statistics need to research and development is a professional algorithm, to have a dedicated company to do it. To this end, the Texas instruments will not be involved in the field of high-end smart analysis algorithms, will not be arranged all the Intelligent analysis of technology, but to provide some basic intelligence analysis capabilities. Their first video co-processor DMVA, providing 5 basic intelligence analysis, including the trigger area, population statistics, camera tampering detection, intelligent motion detection and the corresponding data transfer back to the back-end technology for complex analysis. Wang Ning said: "we provide these capabilities is designed to help the camera manufacturers to achieve differentiation. ”

"The Intelligent analysis of the years did not obtain a good break, because the technology itself is not perfect, make a programme from the user's expectation is still a long way.

"Populus euphratica-said," we will depending on customer requirements, starting from the encoding, video analysis and pattern analysis, road crossing vehicle license plate recognition, demand is high. ”

Semiconductor package: planning for the road map

In the running-in of the manufacturer, the sensor, processor chip infrastructure technology vendors made applicable technology roadmap.

In the field, while the camera is still dominated by CCD, but if 720p high definition impulse in the next year, will bring great opportunities CMOS camera.

Currently on the market two CMOS camera Aptina and OmniVision enterprises are preparing for high-definition market.

"In high-definition market, more than CCD CMOS has advantages.

"Mr. Cheng Aptina Cliff of analysis that" CMOS cameras have improved in low light conditions, photosensitivity is not high and wide dynamic range, so that it compared with CCD exist two disadvantages does not already exist. "Moreover, CMOS camera can achieve high-speed capture, do 1080p 60 frames/sec, CCD can do 1080p 15 frames/sec. In addition, CCD power than CMOS 20% ~ 30%. In terms of cost, high-definition CMOS prices already and standard definition analog prices. He also said that easier than CCD CMOS do intelligent analysis, because CMOS output digital information directly to the processor requirements, send the information. While CCD you need lots of accessories, more cumbersome.

OmniVision programme ' ASD Peng Court Group also told reporters that in this year's 4, 5 months, the camera market for high-definition CMOS camera raises urgent needs.

This indicates a CMOS camera.

At the same time, in the areas of sensor processors, Texas instruments, put forward the concept of a unified platform.

It leverages IP multiplexing technology that will be important for video surveillance IP, such as video co-processor, ISP5 and 2D/3D peripherals, Cortex-A8 and DSP, and display sub-systems C674X, in high school the low-end DVR products and IP network camera products for reuse, allowing customers to invest in unified platform, developing different products, not only simplifies the customer's research and development work, reduces customer costs of maintaining software platform, also accelerates time to market. And to the video surveillance market shocks haisi semiconductors ASIC platform also strengthen the algorithm provides rich peripheral cured and interface methods that reduce customer development threshold and verify the degree of difficulty.
