Previously introduced PC-based ip camera DVR card without departing from the PC system : PC appearance, the architecture of the PC , PC operating systems , PC interface, ...... . Thus it can be considered an extension of a PC application , as long as the exit DVR application (or the application into the background ) , this DVR is a standard PC , the user can easily in MS Office environment document editing , reports, statistics and other operations, ...... . However , because of this , DVR this structure can easily be led invasion of viruses and system failures ; may also be due to hardware compatibility issues or because of some BUG system software , which results in system downtime ; worse, may even be due to system managers own problems ( for example, operating personnel will be placed in the video program running in the background while in the foreground playing games ) and because some mistakenly set , misuse resulting video system unusable. In order from the PC system, a business launched a quasi DVR . But in essence , this DVR does not really from the PC system , because it still uses a PC 's hardware configuration : CPU surveillance camera security systems and motherboard in addition to other peripheral devices , also integrates graphics , sound card , network card , there used to plug PCI video capture card expansion slot , the power section is also used power switching power supply with a fan . However, in order to make it appear in the form of specialized equipment for monitoring the market , the machine adopts the overall design. Based DVR PC compared with the preceding , this quasi- embedded DVR PC full use of hardware resources , and to effectively take account of the overall spatial layout of the machine is more compact , but also effectively reduce the volume dedicated to achieve control the hard disk recording system . Equator has introduced high-speed broadband DSP chips , also known as MAP-CA Broadband Signal Processor (BSP, Broadband Signal Processor), which can operate at high speed clock of 300MHz , the processing capacity of 30 GOPS (Giga Operations Per Second, that every 30 billion times a second integer arithmetic ) , equivalent to approximately 6.4 times the processing speed of the Pentium III , mainly for high-performance, large amounts of data broadband video applications, such as embedded DVR (DVR), embedded network video server (DVS) as well as digital set-top boxes , digital TVs, video conferencing systems, medical imaging products. Here , MAP-CA is Equator's MAP series of very long instruction word VLIW (Very Long Instruction Word) processor in one of its latest MAP-BSP-15 to further increase the operating frequency of 400MHz, so the data processing capacity of 40GOPS ( video encoding ) . MAP-CA consists mainly of a very long instruction word processor core , a programmable bit-stream coprocessor (The VLx), video filtering coprocessor , the display refresh controller and rich digital I / O interfaces. MAP-CA supports a variety of software to achieve video compression and decompression of image and signal compression algorithms such software is relatively hardware implementation has great advantages , very easy to upgrade . ADI's ADSP-BF5xx Seriesip camera system network camera ADI's ADSP-BF5xx processor is developed on the basis of its Blackfin family of processors on . Multiple functional blocks which Blackfin family of processors cores can support 8/16/32 bit integer data and 16 / 32 fractional data , in particular the four 8-bit video arithmetic logic unit (ALU) can be addressed include MPEG-2, a number of multimedia algorithms , including JPEG and MPEG-4 , so that a processor can process audio, video , imaging, and data information . The Blackfin series of upgrade products ADSP-BF533, ADSP-BF532 and ADSP-BF531 Blackfin series not only inherits the advantages of the product is easy to use and code-compatible , but also significantly improves performance and reduces power consumption. These three new pin-compatible processors , the difference is only a difference in its performance and capacity on-chip memory , the NVR Recorder security camera system is easy to upgrade the performance of new product development and reduce many of the risks .
