Security has always been a relatively independent, closed market, and with the video surveillance, especially network video surveillance in 2007, the popularity of monitoring equipment and monitoring systems rapidly toward the digital, network-oriented direction, IT technology to become the security field Support technology, play an increasingly important role in the construction of safe city and safe community. With the accelerating pace of China's urbanization progress, China is already the largest construction market in the world with an annual completed floor area of ​​nearly 2 billion square meters. Most of these buildings are located in cities, making them intelligent and safe High expectations. Particularly worth mentioning is the stimulating effect that Beijing hosted the Olympic Games in 2008, the World Expo in Shanghai in 2010 and the Asian Games in Guangzhou, making the safety investment in transportation and public places in these cities rapidly increasing. At the same time, the security needs of public places such as libraries, museums and parks have also spawned the start of mass surveillance of video surveillance systems. Video Security Monitoring System has become an important measure of security. Through experience, we summarize the technology of video security monitoring system into four categories to adapt to the combination of modern video development technology and Internet communication technology, improve the technology of image recording and transmission and conversion, Promote the development of video security monitoring system and realize the smooth and stable operation of security monitoring system. The following, mainly from the following four aspects of the video security monitoring system of key video technology to explore: First, infrared thermal imaging technology Surveillance cameras can be monitored to the naked eye can not see the picture, it is because of the use of infrared, the use of infrared imaging technology, this infrared image is called thermal images to detect such as nighttime targets, and through photoelectric conversion, signal processing and other means, The device that converts the temperature distribution image of the target object into a video image is called an infrared thermal imager. Infrared imaging in the field can play an important role: 1. Night and low visibility monitoring applications 2. Smoke, fire monitoring 3. Hidden target and camouflage target identification Second, the image sensor technology Video security monitoring system is the core part of the spread of video images for the monitoring of the screen image sensor from the CCD to the CMOS change from the two technologies are different, CCD-based probe compared to CMOS probes with higher integration Because CMOS sensors integrate many peripheral processing functions, fewer components are required than CCD probes and CMOS probes consume much less power. From the entire system point of view, CMOS sensors can greatly reduce the cost. However, the CCD has neither the ability to record graphics data, nor the ability to permanently save, or even do not have the "exposure" capability. The CMOS processing can also be used as a digital camera sensor, you can largely reduce the cost. Third, intelligent monitoring of video display technology Intelligent video processing technology is a certain analysis capabilities to achieve artificial intelligence on the image and image description to establish a mapping between the image analysis and processing, automatic analysis and extraction of key information in the video source. Helps people to automate identification and reduce manual labor. Fourth, streaming media technology The monitoring of the screen to store and playback are two basic essentials, on the one hand to ensure smooth video, on the other hand to ensure the clarity of transmission, we can front-end camera as a real-time A / V source, and the video file Think of it as a stored A / V file, so a good way to solve such problems is to use streaming media technology. Through the brief analysis of the above technical principles to meet the installation and transmission of video surveillance essentials, Shanghai monitoring project in the installation of technology and function to achieve the above standardization, but also need a comprehensive set of media distribution and scheduling mechanisms to ensure efficient media delivery.
