Analysis of NVR mainstream chip solution

In recent years, the IPC+NVR solution portfolio has achieved remarkable results in the video surveillance market due to its cost-effectiveness, flexible deployment, and other advantages. With the addition of more and more NVR manufacturers, the NVR market is unprecedentedly prosperous. As the core component of the NVR, the chip plays a decisive factor in the market positioning, performance, and cost of the NVR. Therefore, each upstream chip manufacturer continues to innovate and develop high-definition chips with higher decoding capabilities and stronger processing capabilities. At present, there are mainly four kinds of NVR mainstream chip solutions on the market: TI DM816X series, Hass 35XX series, Entropic EN7530 series, and Marvell ARMADA XP series. Market share, market strategy and planning, and product series from chip manufacturers are as follows: The advantages and disadvantages of the product are briefly discussed.

TI DM816X Series

As a veteran of the video surveillance industry, TI has performed well both in IPC applications and NVR applications.

The DM816X series is widely adopted by manufacturers such as Haikang for its excellent performance, and is used in project-based NVRs, network decoders and other products. DM 81XX is the most flexible and programmable DSP in the world. It can make many innovative products. This is the original intention of TI to design this series of products. It is also the main reason why Haikang and other companies choose this series of chips. Taking the DM8165 chip as an example, the chip can be configured with up to 2GB of memory, and a single chip can meet the access and forwarding of 160M network IPC resources, and can easily handle 16-channel 1080P and 16-channel 1080P decoding. As a leading international chip manufacturer, TI has unparalleled advantages and advantages in its technological leadership.

Since the launch of the DM816X series in 2010, the overall architecture has only been slightly optimized. After three years, its chip processing capability is still ahead of the chip processing capabilities of other manufacturers. The forward-looking nature of the technology is evident. Compared with other chip manufacturers in China, TI is more focused and focuses on the research and development of the core underlying technology, which ensures that TI has a leading edge in technology. Then precisely because of TI's technical focus, which led to its lack of investment in chip applications, the main performance of the following two points:

1. The support for the upper application is not enough, NVR manufacturers often have to invest huge R&D resources, costs, and time to develop products, leading to enterprises with scale advantages such as Haikang can guarantee continuous investment, and other manufacturers rarely dare to try , And domestic chip manufacturers in the application follow up very quickly, for example, Hass recently launched a chip built-in cloud services, can facilitate NVR manufacturers to quickly develop their own cloud applications;

2. Due to the leading technology and forward-looking nature of technology, TI often has to invest more in R&D and production, so the cost of TI chips is higher. In recent years, with the increasingly fierce competition in the NVR market, the TI chip With high costs, more and more small businesses are deterred and the market share is gradually lower. Currently, in addition to Haikang and other high-end or special areas (in addition to video surveillance, TI8168 can also be applied to video conferencing, video telephony and other fields) manufacturers, few other manufacturers use TI's NVR chip.

Hass 35XX series

Hass as the upstream chip manufacturer's performance, its performance in the video surveillance industry has been very bright in recent years. In the NVR market, high-end product lines successively introduced Hass 3531, Hass 3535, and continuously enriched and improved low-end product lines, such as the Hass 3515A and 3520D chips after optimization, and the product line covers different markets of high, medium and low levels. Can develop a variety of performance and application of NVR, NVR market because Hass's space to join the boom. Hassima has been able to become the largest supplier of NVR chips in a short period of time, depending on HiSilicon's focus on chip-level application support and low-cost advantages. Although Hass's chip maturity and technology are inferior to those of TI, Hass offers a complete set of development kits, which reduces the threshold for development. SMEs need only to invest less resources to quickly develop products that can meet their own applications. The satisfaction of the security market for application innovation needs.

With fierce competition in the security industry, Hass uses its advantages in technical support to enable users to focus more on the business application level, reduce SME investment in R&D, and help users quickly introduce on-demand services. Product; Secondly, Hass products have low cost. Although the performance of the products is slightly lower than that of other manufacturers' chips in the same series, it is enough to meet the needs of most applications. In short, Hass chips are technically not the best, but they are the most practical and most satisfying of the current market demand.

Currently, most of the NVR manufacturers on the market use Hass chips, such as Zhejiang Dahua, Shanghai Weishiqing and Hangzhou Xiongmai.

Marvell ARMADA XP Series

Hikvision released the DS-96000 series NVR products based on Marvell chips in March this year. It can access 128 HD network cameras with 400M network access bandwidth. This is based on the release of Shanghai Weishiqing in April 2013. The second official Marvell chip released an NVR manufacturer based on Marvell chips and pushed Marvell's rising star to the spotlight. At this point, large-capacity high-definition storage products from the traditional X86-based IPSAN to the ARM-based embedded IPSAN opened the curtain.

Marvell ARMADA XP is the world's first commercial quad-core ARM server processor designed for server applications in enterprise-class cloud computing environments. More and more Internet and cloud service companies are moving from existing architecture servers to embrace more energy-efficient ARM architecture servers. Baidu's previous deployment in the ARM server industry also confirms the direction of application of large-capacity data storage: ARM technology will drive Everything from mobile devices to large enterprise data centers.
