In security products, the chip is in a very core position. The chips in security are mainly front-end cameras, codec devices, NVR, DVR, video storage IPSAN and various processors used by various back-end servers, which are similar to the CPU of a computer. The security industry is generally called DSP or ISP, SOC, etc.

classify

According to different products, we can divide the processors in security products into the following categories:

camera

There are two kinds of processors in general cameras, one is to process images. For example, the processor commonly used in analog cameras and SDI digital cameras is called ISP. The other is used by network cameras and coding equipment. Its main function is to encode and compress analog and digital signals into network signals, called SOC or DSP. Generally, this processor also comes with ISP function.

Suitable for NVR/DVR

? The main function of the processor used by DVR/NVR is to encode and compress the video signal connected to the camera (whether the camera is analog or network), and at the same time support VGA/HDMI decoding output display and access to the hard disk for storage. At the same time, it also supports audio, alarm input and output, network, intelligent analysis and other functions.

Server usage

The security server uses the same processor as the ordinary professional server. The core functions are calculation and operation, information processing, program running, etc.

General processor of network camera

General processor for analog camera

General processor for DVR/NVR

Server processor

development trends

Mainly from abroad, occupying the vast majority of the domestic market.

The early safety processors were mainly produced by foreign and Taiwan Province manufacturers such as Ti and Anba, but now they are mainly produced by domestic manufacturers such as HiSilicon, Guo Ke and Zheng Jun. Among them, Hayes should occupy 70% market share at present.

From SD to HD.

At present, 3 million, 5 million, 8 million or even 6.5438+0.2 million webcam processing chips encoded by H.265 are increasingly entering the market. Push security from early standard definition, high definition and full high definition to 3 million, 5 million or even higher high definition era.

More AI functions.

The early intelligent analysis function of the security chip was weak, and now the basic intelligent analysis function is standard. The processor has built-in functions such as human detection, face recognition, demography, license plate recognition and so on.

Bring your own computing power.

In addition to the common AI functions, relatively high-end processors also have their own computing power, support deep learning, and can perform more operations related to intelligent algorithms.

Cloud edge combination, decentralization.

More and more front-end camera chips have AI function and their own computing power. Many intelligent analysis that can only be done in the center in the early days can be done on the camera side, which reduces the pressure on the center. The combination of cloud and edge makes the system data more reliable, safer and more disaster-tolerant.
