On NVR mainstream chip solution
In recent years, IPC + NVR its portfolio of cost effective, flexible deployment and other advantages in video surveillance has made remarkable achievements in the market, as more and more of NVR manufacturers to join, NVR market unprecedented prosperity. NVR chip as the core components of NVR's market position, performance, cost plays a decisive factor, therefore each upstream chip manufacturers continue to introduce new, higher R & D decoding capabilities, more processing power of HD chip. NVR currently on the market mainstream chip solution mainly in the following four kinds, namely TI DM816X series, Hass 35XX series, Entropic EN7530 series, Marvell ARMADA XP series, the occupancy from chip manufacturers to the market, market strategy and planning, product line explore the advantages and disadvantages such as product simple.
TI DM816X series
TI as a powerhouse video surveillance industry, whether in the application or in the IPC NVR applications, both have good performance.
DM816X series rely excellent excellent performance, Kang and other manufacturers are widely used for the NVR project type, decoders and other network products. DM 81XX is the world's most flexible programmable DSP, can make a lot of innovative products, which is the original intention of TI design of the products, but also the main reason for the chips of Kang and other companies use. With DM8165 chip, for example, the chip can be configured with up to 2GB of memory, a single chip can meet access network IPC resources and 160M forward, easy to deal with 16 and 16 1080P 1080P decoding. As a leading international chip manufacturers, TI superiority and advantages in terms of technology leadership glance.
DM816X series since the 2010 launch, the overall architecture only do a little optimization, three years after its processing power is still ahead of other manufacturers of chip processing power, its forward-looking technology is evident. Compared to other domestic chip manufacturers, TI is more focused, more focused research and development of the core underlying technology, which guarantees TI technical lead. It is because TI then focus on technology, resulting in insufficient investment in its chip applications, mainly the following two points:
1, the upper application support is not enough, NVR manufacturers often have to put a huge R & D resources, costs, time to develop the product, resulting in addition to Kang and other companies have advantages of scale to ensure continued investment in other manufacturers rarely dare to try , while domestic chip manufacturers to follow up on the application very quickly, such as the introduction of chip Hass recently built cloud service, they can easily NVR manufacturers to quickly develop their own cloud applications;
2, due to the type and forward-looking technology leadership, TI in R & D and production tend to put higher costs, higher costs TI chip, but in recent years with NVR increasingly fierce market competition, TI chip cost more and more small businesses are prohibitive, so the market share gradually decline. With the exception of some specific areas targeted at high-end or for Kang, etc. (in addition to video surveillance, TI8168 can also be applied with video conferencing, video telephony and other fields) manufacturers, few other manufacturers use TI's chip NVR.
Hass 35XX series
Hass upstream chip manufacturers as the mainstay of its performance in the video surveillance industry in recent years, very bright. NVR market in high-end product line has introduced a 3531 Hass, Hass 3535, while continuing to enrich and improve the low-end product line, such as optimized Hass 3515A, 3520D and other chip, low product line covers high school different markets, users NVR can develop a variety of performance and applications, NVR market because Hass added space prosperity. Hass has been able to NVR became the largest supplier of chips in a short time, depending on Hass chip attaches great importance to the application level support as well as low-cost advantage. Hass chip and technology maturity, though not as TI, but Hass offers a complete development package, reducing the threshold for the development of SMEs only need to invest fewer resources can quickly develop products to meet their application, good to meet the security needs of the market for innovative applications.
Security industry competition, Hass virtue of its advantages in terms of technical support, allowing users to devote more energy to focus on business application level things, reduce the investment on R & D in SMEs, to help users quickly launch on demand products; secondly Hass low-cost products, although compared with the same series of other chip manufacturers, slightly less performance, but good enough to meet the needs of most applications. In short, Hass chip though not the most technically excellent, but they are the most practical and best meet the current market demand.
Currently on the market most of the NVR manufacturers are used in Hass chip, such as Zhejiang Dahua, Shanghai Wei as clear, Mai Xiong Hangzhou and so on.
Marvell ARMADA XP series
Hikvision in March this year released a DS-96000 Series NVR products based on Marvell chip 128 can access high-definition network cameras , network access bandwidth 400M, which is following the Shanghai Wei Qing, as the release based on April 2013 the second house after the official release Marvell chip-based NVR chip manufacturer Marvell, the Marvell rising star pushed into the spotlight. So far, large-capacity high-definition storage products from traditional X86 architecture IPSAN embedded ARM architecture IPSAN transition toward the curtain opened.
Marvell ARMADA XP is the world's first commercial quad-core ARM server processor, the server computing environment designed for enterprise-class cloud applications. More and more Internet and cloud services companies are shifting from the existing server architecture to embrace more energy-efficient ARM-based servers, Baidu had deployed in the ARM server space also confirmed the application direction of the large-capacity data storage: ARM technology will drive all fields from mobile devices to large enterprise data centers.
In the security industry, currently Hass, TI and other chip manufacturers, NVR single chip can be expanded to 36 channels and decode HD access network cameras, there are thousands of paths for the IPC distal end, a rear end of the large capacity storage needs centralized deployment program, if using an existing NVR, often require dozens NVR stack up very occupied room space and caused great difficulties to management; and traditional centralized storage deployment is generally used to build X86 architecture IPSAN each device can access passage 100 or more high-definition cameras , but this is expensive, and based on the X86 architecture IPSAN high due to the coupling, between a high-power chip hardware is often poor stability. In response, Wei as SD Hikvision launched based on Marvell chip (model MV78460, 4-core 1.6GHz) ARM architecture can support multiple number, mass storage, iSCSI protocol support, specifically applied to video surveillance industry the IPSAN, with high stability, high cost and so on. Trends mass storage device will be like the analog era, industrial-type embedded NVR DVR as to change, based on ARM architecture-based embedded IPSAN will gradually replace the X86 architecture IPSAN.
Currently, the Hikvision Wei as clear and ARM-based embedded IPSAN once launched immediately sought after by the market, I believe more and more companies will be added to the Marvell camp. However, compared with the Marvell chip Hass, TI chip, there is a lack of decoding chip itself does not have the display function, the need for expansion decoding display interface through PCIe. But the wall itself is stored on the real-time decoding applications for real-time monitoring of the user application can be achieved by incorporating the image decoders and other network equipment as a centralized storage device, users are more concerned yes.
Entropic EN7530 Series
Then the late show of Marvell, have to mention the video surveillance industry decline of aristocracy Trident. This from the door NXP multimedia department, and later with the acquisition of Entropic business on the road network high-definition monitor does not go smoothly, because of its corporate positioning, the security industry is now gradually fade out.
In 2010, Trident and TI almost the same time released a high-definition video storage decoder chip PX8400, can handle access to store and decode 16 720P, and this has focused chip manufacturers high-definition set-top boxes, and chip a launch, because of its excellent image sharpness, color saturation, image reproduction, and ultra-low power consumption advantages, has attracted a large number of manufacturers to join Trident camp, of which there are Shanghai Wei as clear, Hanbang Beijing, Shenzhen and other professional NVR same manufacturer, however, due to a serious lack of difficulty of its product development and technical support, so that some manufacturers for R & D investment and development cycle considerations and early exit. NVR manufacturers due to the lack of participation is not formed on the downstream ecosystem integrity, making TRIDENT video surveillance industry has been hobbled, though late Trident launched a higher-performance chip, but it has reduced the number of SATA interface, leading to the chip can not expand 8 SATA interface, making the NVR manufacturers can not produce the 8-bit market share NVR mainstream status. With the exception of Shanghai Qing Wei as the use of Entropic EN7350 developed and produced a bit NVR, but now very few companies use Trident chips.
Conclusion
With the NVR industry development and maturity, the future pattern located upstream chip manufacturers exactly what changes will happen, we'll see
