CMOS sensors have been able to revitalize the growth of the CCTV surveillance market in the past two years. The main reason is that due to the significant increase in the performance of CMOS sensors, the image resolution has increased to 600-700 TVL, and in the future it can even jump to 750-800 TVL. CMOS itself has made great progress in high temperature range performance, high integration, chip size, low power consumption, and low cost, thus laying a solid foundation for the development of analog surveillance cameras toward higher definition.

According to surveys, the global surveillance camera market will maintain steady growth in the next five years. In 2013, global surveillance camera shipments are expected to be about 85.6 million units. By 2017, this figure will rise to 114.5 million units. On the one hand, in the analog surveillance market, especially in the past year or so, camera solutions based on lower-cost CMOS sensors have been widely recognized in the market, and the image resolution has been raised from the original 500 TVL to 700 TVL. And the overall cost of the camera is also much cheaper than the CCD sensor solution. These immersed analog surveillance markets have triggered a new wave of image resolution upgrades. It also allows people to see that the analog surveillance market is still full of vitality while the networked solutions are rapidly developing.

On the other hand, the high-speed growth of the IP surveillance market is still the main theme in recent years. 720p and 1080p high-definition cameras have become the main force in the market at present, and products with higher image resolution of 10MP and 4K2K are also in the making. . After obtaining the high-definition monitoring experience, the user also puts forward higher requirements on the IP monitoring system. It is hoped that the high-definition IP surveillance camera can bring greater commercial value and have more intelligent functions.

With the rapid growth of analog surveillance and IP surveillance markets, in order to further meet the application requirements of the surveillance market, many top security companies adopt a different approach than the traditional RGB color filter method, in which full-color clear pixels span the visible spectrum and collect more than green pixels. Multiple times more light to achieve better low-light performance, and the spectral shape of the transparent pixels has been carefully designed to greatly improve image quality, signal-to-noise ratio (SNR), color reproduction, and system robustness.
