In the field of security chip manufacturing, international enterprises once occupied the mainstream market; In the past two years, with the in-depth promotion of domestic smart cities, the demand for security has become increasingly strong, the domestic security technology has been greatly improved and improved, and the strength of domestic security chip manufacturers represented by Hisilicon is rising.
1、 Foreign chip manufacturers
Foreign chip manufacturers mainly include NVIDIA, Intel, anba, Ti, Sony, Tewei, Samsung, Google, etc.
As an old chip manufacturer, NVIDIA has been deeply engaged in the security industry for many years and has cooperated with many enterprises in the security industry. In recent years, the chip scheme with GPU as the core has been applied to the new products of many security enterprises such as Hikvision, Dahua Co., Ltd. and Yushi technology.
Intel is another chip manufacturer that cooperates closely with the security industry. Relying on the end-to-end full stack strength of the Internet of things and the advantages of in-depth learning technology, Intel has also established in-depth cooperative relations with Hikvision and Yushi technology.
Anba, as a young team, focuses on video compression and image processing. It adopts ISP coding, which has low code stream and good stability. It is loved by the medium and high-end market, but its lack of openness and simple molding also limits it.
Sony, Samsung, Google and other international well-known enterprises’ involvement in security chips mainly stems from the development of artificial intelligence and the company’s demand for the expansion of security business. At present, there is little cooperation with security manufacturers.
2、 Domestic chip manufacturers
Domestic manufacturers mainly include Hisilicon (Huawei), guokewei, zhongxingwei, Beijing Junzheng, fuhanwei, jingjiawei, Cambrian, Shenjian, zhongkeshuguang, etc. they have layout in the field of security chips.
As a chip manufacturer of Huawei, Hisilicon is a pioneer in domestic chips in the security industry. Hisilicon’s technology with h.265 standard as the core is a cost-effective choice for domestic security manufacturers. The chips developed by Zhongxing micro with SVAC standard as the core also have a certain influence in the domestic security industry. Taking the development needs of artificial intelligence as the core,
The development of DPU chip (FPGA) of Shenjian technology, NPU coprocessor (ASIC) of Beijing Junzheng and AI server chip (ASIC) of Cambrian have injected vitality into China’s chip industry!
Among them, Hisilicon has a relatively perfect layout, occupies a large share in the ipcsoc market, and has covered the cloud and edge. The following is the layout of major domestic manufacturers in the field:

3、 Rise of Hisilicon chip
In 2018 and 2019, the large-scale application of security industry combined with artificial intelligence technology ushered in new development. The development of the industry brought by AI + security is inseparable from three basic elements, namely algorithm, data and computing power. Among them, the key of computing power is the chip. As the global leader of IPC chips, Hisilicon has brought up to 20 highly competitive and advantageous chips, accounting for 70% of the global SOC market.
The rise of Hisilicon should start with the improvement of video surveillance resolution. Video surveillance accounts for about 60% in the security industry. With the improvement of lens quality and sensor performance, the resolution of video and image is higher and higher, and the amount of original data is also larger and larger. If there is no good coding algorithm to compress the volume of files, these data can not be stored and transmitted at all. The video based codec standard came into being in the late 1990s with the emergence of video recorders, VCDs, DVDs and other devices. The MPEG2 compression standard is used in VCDs.
As the back-end equipment of video surveillance, the traditional video tape recorder needs to use a large number of tapes, which consumes a lot of storage space and physical space, and it is very inconvenient to access historical data. Hard disk video recorder DVR has large storage capacity and can manage multiple hard disks, so the large-scale back-end digital transformation began. The mainstream hardware solution of the first generation DVR is still from foreign manufacturers, such as SAA7113 + pnx13 of Philips; By 2005, the second generation of DVR began to adopt MPEG4 / H.264 compression algorithm. Hisilicon’s H.264 video codec chip appeared in the market at this critical time point. In the period of rapid development of DVR, it grasped the core demand of the industry – video codec capability, so as to develop and grow rapidly.
Now, on the premise of the same image quality, the compression ratio of H.264 is more than twice that of MPEG-2 format, the compression ratio can reach more than 100:1, and the compression ratio of h.265 is twice that of H.264. Huawei now has a great participation in the international standards of codec, and a large part of its contribution comes from Hisilicon.
Looking at the whole chip market, NVIDIA (for GPU) and Intel (for CPU) are still at the top. For the security monitoring SOC market, Hisilicon can be said to comprehensively suppress other competitors. Now, video codec chips are concentrated on SoC system level chips (system on chip, which encapsulates multiple chips on the circuit board and embedded software into one chip, and can complete the function of an electronic system on a single chip). In the IP Camera SOC market, codec capability is the core element. It is not difficult to understand that Hisilicon can do well in codec, so it can integrate on-chip peripheral resources to provide a series of SOC solutions. Now, based on the IP Camera SOC, Hisilicon has launched a new intelligent chip and has formed a series of products: hi3559av100, hi3519av100, hi3516dv300 and hi3516cv500.
