In the global digital image surveillance market industry, in recent years, with the advancement of digital imaging technology and the gradual popularization of prices, the global output value has continuously reached new highs. It is estimated that the output value of the global digital video surveillance market has reached US $ 10.5 billion in 2011, a growth rate of 23% from 2010. In 2012, it is estimated to increase to 13.5 billion US dollars, a 28% increase from 2011. At the same time, with the increasing demand for digital video surveillance in the global market, it is estimated that the output value in 2015 will reach 25.5 billion US dollars. Among them, the compound growth rate from 2011 to 2015 reached 20%, better than the general electronics industry level.
According to PIDA, with the emergence of a series of related digital video surveillance (Digital Video Surveillance) products based on digital cameras, plus technology and price specifications are cheaper than in the past, so now "Digital network video surveillance" has gradually replaced the old analog CCTV (Closed Circuit TV) video surveillance system.
In the future, network image monitoring related application products, due to the continuous progress of semiconductor manufacturing processes, the current CMOS Sensor can provide faster speed and cheaper price than CCD. The CMOS image sensor image monitor with IP network can provide a more comprehensive monitoring system than the previous analog monitoring system. The common surveillance cameras (Network Surveillance Camera) in daily life are generally known. According to whether they are connected or not, they can be divided into network IP surveillance cameras (IP Surveillance Camera) and remote control surveillance cameras (Remote Control Surveillance), for example: now common The remote control surveillance system (Remote Control Surveillance) of the outdoor parking lot image surveillance system needs to operate in a place with a high temperature difference, so the required specifications are high, and the specifications such as high resolution, high pixels and H.264 compression standard specifications are taken into account. The development of mainstream digital CMOS image monitoring systems is booming.
