What's the outlook of the security industry?
Overview of 40 years' development of anti TechnologyAt the end of November 2011 I went to Shenzhen to participate in the Shenzhen Expo security, see a lot of companies hit the slogan "HD era", "security industry entered the era of high-definition" etc.. If it is to do some video surveillance enterprises say it, but I saw a lot of media also said "this is followed in the HD exhibition theme" HD "era coming now is that there is something wrong. For a time, give the user an idea, as if now the security industry mainstream technology is "HD", the remaining problem is "HD era" has arrived, or will come, not yet determined.
Surveillance lens and storage developmentSurveillance camera seriesAnalog technology video camera of the 70-80: transistor technology, camera, resolution of about 480 lines, basically no digital technology;Analog technology in 80-90, solid chip camera: CCDCMOS camera, the initial resolution of about 380 lines, gradually increased to 510 lines;90-00's IP digital camera with video server: early video encoding for the IP signal, the subsequent development of IP camera based on IP technology, the total number of pixels is about 300 thousand - 450 thousand, equivalent to about 480 line camera.00-10 HD applications: HD IP cameras, based on high-density CCD technology. The total prime number is about 1 million 300 thousand - 2 million;10- digital analysis technology: ultra high definition IP camera, embedded into video analysis, with early warning function, face recognition, object position identification and other digital security cameras;
The process of technology development in security industry:We use graph to describe the general development process of security technology in the last forty years.The graph briefly describes the technology development process of the security industry in the past forty years, and analyzes the basic five sub industry cameras, pan tilt lens control, video recording, information transmission, detection and alarm. These five sub sectors are listed horizontally. And vertical is along the track of time, from 70s security industry just started in the era, until now, to the end of 2011 security Expo express the trend.
