Analysis: video surveillance-related technology development and market trends – video surveillance, development, marketing – Security Industry
The first video surveillance system is all analog video surveillance systems, also known as closed-circuit television monitoring system (CCTV). Image information using the video cable, to simulate the way of transmission, transmission distance is usually not too far, mainly used in small scale monitoring, control image usually only in the control center view. All analog video surveillance systems for analog video Matrix VCR-type recording device and tape core. With the development of digital technology, digital video surveillance system from the mid 20th century, began to appear 90 to digital control of the video matrix replace the original analog video matrix, in order to figure DVR Replace the original time-lapse simulation DVR recorder, the original tape storage mode into digital storage of video, analog video to achieve digital video. DVR set the VCR, the picture Splitter Functions, taken the first step in digital surveillance. On this basis, produced a fully digital video surveillance system can be based on PC, or embedded devices, constitute a monitoring system, and multimedia management. Such systems is the video surveillance Market Mainstream. With the popularity of broadband, video surveillance gradually from the local control to remote monitoring development, there have been Network Video Server on behalf of the remote network video surveillance system. Network Video Server to solve the video stream transmission problems on the network, starting from the image capture digital processing, transmission, thus allowing more diversity in the choice of transmission line, as long as the network place, provides a video transmission possible. The whole system towards platform and intelligent. Many Internet Enterprise Has started to engage in the development of such video surveillance systems, now is still the market early stage. Advances in video surveillance related technologies (1) CMOS Image Sensor Technology matures
Surveillance camera image sensor is a gradual shift from the traditional CCD to CMOS changes. Both sensors have length, but has been, CMOS sensor defects gradually decrease. CMOS image sensors, low-cost, high integration of its main features, image quality has not lost in the CCD. Compared with the probe based on CCD, CMOS sensor’s integrated high, because CMOS sensor incorporates many peripheral processing, the device required less than the CCD sensor and CMOS sensor’s power consumption is much lower. From the view of the whole system, CMOS sensor costs can be greatly reduced. (2) intelligent analysis technology IEEE Intelligent image 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 to avoid the interference caused by the light changes. As the background image of the dynamic changes, such as weather, light, shadow and confusion interference effects, makes motion detection into a very difficult task. Early motion detection is encoded I frame produced a comparative analysis of the video frame by comparing the change detection image. The methods most commonly used background subtraction (Background Subtraction), the time difference (Temporal Difference), optical flow (OpticalFlow), motion vector detection method. (3) chip technology to provide new products for video surveillance programs
IP cameras are usually integrated video capture, video encoding / processing and network interface functions. In the video surveillance market, to support these functions, the performance of various video signal processor chips vary widely, but also highlight the advantages of most products. At least from the functional requirements of the low-end products to high-performance multicore digital signal processor (DSP) chip for high-end products for different market requirements of the video signal processor very different. High performance DSP chip video processor to enhance 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 advanced
Previous image format digital video surveillance mainly MJPEG and MPEG2-based. With the improvement of image compression technology, there has been more and more advanced video compression formats such as MPEG-4, H.264, China is to develop with independent property rights of AVS encoding format. Video compression technology for video surveillance in image transmission, video storage and so bring great benefits. New features video surveillance market With the popularity of broadband, video surveillance from a local monitor to the gradual development of remote monitoring, appeared on behalf of a network video server for remote network video surveillance system. Network Video Server to solve the video stream transmission problems on the network, starting from the image capture digital processing, transmission, thus allowing more diversity in the choice of transmission line, as long as the network place, provides a video transmission possible. The whole system towards platform and intelligent. Many Internet companies have started to engage in the development of such video surveillance systems, now is still the market early stage. Same time, we also noted that the traditional video surveillance business in terms of geographical coverage, or user group coverage, the range is very narrow, and this year the development of video surveillance platform presents some characteristics different from the past, and gradually to the large geographical , multi-field extension of the range of applications broader, more comprehensive. 1. From individual to multiple areas of the industry
In the past, China’s video surveillance applications, mainly in government departments and finance, public security, transportation, electricity and other special departments and industry. Among them, the government and the financial sector accounted for 20.9%, respectively and 20.6% market share. However, with advances in information society, more and more industries and areas of significant increase in the demand for video surveillance, even the traditional users of public security that are “Green City” of the city made a new pattern of control and function requirements. This year, the video surveillance began banking, transportation and other individual areas extend to many fields, from the traditional management control and security monitoring to monitor the development of production and operation. In addition, the video surveillance industry, the situation only for enterprises have gradually been broken, the public has also become home video surveillance applications in 2008 a new market. Family in the public market, mainly used in residential video surveillance of security and property surveillance. Users can install the camera at home, using home gateway as a video server, the user remotely through the Internet in real-time monitoring home security. Although the full realization of the digital home away from relatively far away, but with IPv6 technology and information appliance technology, further optimization of mobile monitoring equipment
