Security for high-definition monitor the effect is really nothing to do with the camera chip?
There are media reports that the security for high-definition monitor the effect of the camera chip has nothing to do, "the article caused the industry a sigh. The article said: "At present the development of IP-definition, or HD evaluate the pros and cons, is to choose what chip, with emphasis on what kind of applications based on off-the-shelf programs can make." This perspective has helped many professionals speechless, security HD monitoring the effect is really no relationship with the camera chip?
The answer is no doubt the negative, it is well known, the core components of the surveillance IP camera is an image sensor and a video processing chip, to achieve good image quality, in addition to the distal end lens camera processing, the image processing section, the sensor portion of the light is also not be ignored. ring. Chip as the core processor, the effect of high-definition monitor is plays an important role.

ISP join hands DSP chip to enhance the monitoring quality
The ISP (imagesignalprocessor, image signal processor) is an important device in the CMOS and CCD camera, the main function is for processing the charge information of the CCD (or CMOS) accumulation in the imaging process, including the linear correction, noise removal, removal of dead pixels , the interpolation, white balance, auto exposure control, and so on.
DSP (digitalsingnalprocessor) is a unique microprocessor based digital signal processing large amounts of information devices. Directly from the image sensor is bad, regardless of color or detail of the actual image, can only see the broad contours of the objects in the image. Using a dedicated DSP chip as the ISP can greatly improve the camera's video processing and operational performance. ISP processing, including interpolation, de-noising, go to the dead pixel edge enhancement, color correction, white balance and other operations, you can make the images more delicate, closer to the image of the real world.
Camera with low-light, wide dynamic through the fog often using a dedicated DSP chip for processing. Thus what kind of image sensor processing DSP chip impact effect, thereby affecting the results of monitoring. Thus, monitoring the effect of the camera chip is closely related to the not unrelated.
HD IP Camera inside the compression chip and CPU processing power are higher, and the processing power of the chip is mainly reflected in the resolution, low bandwidth, multi-stream applications. HD IP Camera vast majority of IPC, IPC video codec and compression inevitable loss, there are also different in different video codec and compression processing chip compression ratio and image quality. Processing chip compression ratio is greatly affected high-definition monitor quality better or worse.

Chip upgrade only to improve the monitoring results
The chip has been restricting the development of China's electronic industry, for many years has been the people's heart disease, people have been eager to get rid of "foreign chip" to contain. Terms of security, the chip has been a key factor in restricting the definition of monitoring, in recent years, in order to enhance the image effect, some companies actively developing chips to enhance the functionality. Sony, for example in order to enhance the CMOS chip image effects, including sensitivity and wide dynamic, in particular, has developed a new feature - View-DR. This function contains three advanced technologies: multiple exposures wide dynamic technology, enhanced visibility (VE) technology developed by the professional security monitoring high sensitivity ExmorCMOS.
Generally wide dynamic open sensitivity will be reduced, but by opening the View-DR function, not only the wide dynamic range over 120dB, and compared to traditional wide dynamic sensitivity 2-fold increase, while the contrast increased four times, the image effect greatly enhanced and improved in low light and strong chiaroscuro. Noise control in high-definition surveillance IP Camera, Sony also has a unique Super Dynamic Noise Reduction the technology (XDNR), while noise reduction can be guaranteed of moving objects sharp edges trailing.
With the development of millions of HD IP Camera chip, the degree of integration also getting higher and higher, along with peripheral devices will be less and less, will be getting lower and lower power consumption. In order to achieve the system with digital high-definition IP camera have both suitable for image sensors for security applications, also supported by the decoder chip technology for docking with the back-end, back-end decoder chip performance has yet to be a bigger breakthrough. Therefore, innovation and upgrade of the chip to become the focus of the industry.

Security chip high-definition intelligent direction
Prospects for the development of China's chip industry, the State Council released late last year "speed up the cultivation and development of emerging industries of strategic decision" clearly the chip industry as the core of basic industry. Chip huge space for development, toward what direction is the key. Security Industry, HD and intelligent is undoubtedly a hot topic in recent years, the same, high-definition and smart security chip development direction.
With the security chip market growth, the breakdown of the security chip is imperative. Security chip, depending on the applications, broken down into the following different categories: network camera chip, used in network camera products, which is the market in the last two years IPC gradual maturity of the product, these chips focus on high-definition compression, intelligent and ISP processing , such chip market capacity is not as good as the DVR / NVR chip, but can be expected, after a period of time, these chips will occupy most of the security market share.
Auxiliary chips, mainly used for intelligent and ISP business, DSP and FPGA, and analog cameras, such a large number of applications for ISP's DSP or FPGA chip. Intelligence products Intelligence products currently on the market capacity is still in the primary stage for DSP small amount.
Whether the network camera chip, or secondary chip, high-definition and intelligence will become the development direction of the chip. How the speed of the chip to fast track the development of products and industries, as well as how to guide the healthy growth of the industry chain security chip development challenges and opportunities. Chip high-definition impact monitoring results, to play an increasingly important role in the security industry chain, the nation when the chip will help the morale of the security development, and look forward to many security people waiting.
