The monitoring system is the first video of all analog video surveillance systems, also known as Monitoring System Closed-circuit television (CCTV). Information on the image using the video cable to simulate the mode of transmission, the transmission distance is usually not too far, mainly used in monitoring small-scale image control, generally in the control center perspective . All analog video surveillance systems for video analog device Videotaping Matrix-type and tape core. With the development of digital technology, digital video surveillance system from the mid 20th century, began to appear 90 to control digital video analog video matrix replace original matrix to set the DVR Replace original simulation time- Lapse DVR recorder, the soundtrack mode memory storage digital video, analog video to make digital video. DVR set the VCR, the image features Splitter, take the first step in digital surveillance. On this basis, produced a video surveillance system can be fully digital PC based or embedded systems, constitute a system of monitoring and media management. These video surveillance systems is the main market. With the popularity of broadband, video surveillance gradual development of local control of remote monitoring, there was a Network Video Server on behalf of the surveillance system remote video network. Network Video Server to solve the problems of streaming video transmission over the network, from image capture digital processing, transmission, allowing greater diversity in the choice of the transmission line, as long as the place network, provides a video transmission possible. The whole system to the platform and intelligent. Many of the company via the Internet has begun to engage in the development of such video surveillance systems, now even the early stage of the market. Advances in video surveillance technologies (1) CMOS Image Sensor Technology échéanceCapteur comes to monitoring the photographic image is a gradual shift from traditional CCD CMOS changes. The two probes have a long, but has been gradually decreasing CMOS sensor faults. CMOS image sensors, low cost, high integration of its main features, image quality has not lost in the CCD. Compared to the sensor based on CCD, CMOS integrated high because CMOS sensor incorporates several treatment devices, the necessary minimum the CCD and CMOS sensor energy consumption is much lower. In the opinion of the whole system, a CMOS sensor costs can be significantly reduced. (2) technology of IEEE intelligent analysis of intelligence imagery analysis is a more substantial results, such as motion detection, face recognition, target tracking. motion detection is the image in the designated area to identify changes in the presence of moving objects detection and avoid interference caused by light changes. As the background image of dynamic changes, such as weather, light, darkness and confusion of interference effects, allows the detection of movement in a very difficult task. Rapid detection of movement is coded I frame produced a comparative analysis of the video image by comparing the image change detection. The methods most commonly used background subtraction (Background subtraction), the time difference (Temporal Difference), optical flow (OpticalFlow) method for detecting motion vector. (3) chip technology to provide new products for IP video cameras monitoring programs are generally integrated video capture, video encoding / processing and network interface functions. In the video surveillance market, to support these functions, the performance of different video chip signal processor vary considerably, but also highlight the benefits of most products. At least from the functional needs of low-end processor high performance multicore digital signal (DSP) chip for high-end products for different market needs video signal processor very different. High performance DSP chip video processor to improve performance significantly. DSP is the birth of these key elements of smart cameras. Because of the DSP, IP video servers qualified for multiple video streams simultaneously on the intelligent management. (4) video compression format for more avancésPrécédent surveillance digital video image format MJPEG and MPEG-2 mainly based. With improved technology of image compression, there were more advanced video compression formats such as MPEG-4, H. 264, China is to develop property rights independent of AVS encoding format. video compression technology for video surveillance in the transmission of images, video storage and thus bring great benefits. New features video surveillance market with the popularity of broadband, video-surveillance monitor room for progressive development of remote monitoring, appeared on behalf of a network video server for the network system remote video surveillance. Network Video Server to resolve problems in streaming video transmission over the network, from image capture digital processing, transmission, allowing greater diversity in the choice of the transmission line, provided that the of the network, provides a video transmission possible. The whole system to the platform and intelligent. many Internet companies have begun to engage in the development of such video surveillance systems, now even the early stage of the market. In parallel, we also noted that the activities of video surveillance classic terms of geographic coverage, coverage or group of users, the range is very narrow, and this year the development of video monitoring platform has features different from the past and little by little to the vast geographical spread, multi-domain wide range of applications, more global. 1. From a person with multiple areas of industrieDans the past, applications of video surveillance in China, mostly in departments and finance, public safety, transportation, electricity and other special services and industry. Among them, the government and the financial sector accounted for 20. 9%, respectively, and 20. % 6 shares market. However, with advances in information society, more and more industries and areas of significant increase in demand for video surveillance, even the traditional users of public safety that are “green city” of City has a new control scheme and function. This year, surveillance video began banking, transportation and other specific areas extend to many fields, from traditional management control and security surveillance to monitor the production and operation . In addition, the video surveillance industry, the situation for businesses have gradually been broken, the public has also become home video surveillance applications in 2008 a new market. The family in the public market, used primarily in residential video surveillance security and surveillance of property. Users can install the device at home, using home gateway as a video server, the remote user via the Internet in real time home security monitoring. Although the full realization of the digital home away from relatively far, but with IPv6 technology and device information, a further optimization of mobile monitoring equipment
