Software Compression DVR cards

[Guest Echo]

Below is a brief introduction to the main original software compression DVR cards in market.

A) PICO2000 from Canada is an early product and will withdraw from the market gradually because of rapid development of computer technology and appearance of new products. PICO 2000 is not good in video quality, especially when objects move, there are problems of sawtooth, interlaces etc. What's more, its video capture technology is comparatively out of date, especially during the process of video transmission, there's serious problem of frame loss. Thus continuity of video is poor, and video jitters. Another defect is inconvenience in color adjustment. When single chipset card is connected to multi-cameras, the color cannot be adjusted by software, and each channel cannot be set independently. However, because of easy installation, stability, MPEG-4 compression, low harddisk usage, and low cost, it is still widely used by consumers, especially by lower-end manufacturers. But as the appearance of Ether8000 series, PICO 2000's market share and price drop further.

B) Ether8000 series from Shenzhen Wave-particle Intelligent Technology Co., Ltd. is a high-tech DVR product brought forward since 2003. This product adopts modern computing technology, and makes great improvements not only on hardware, but olso on software. For hardware, Ether8000 DVR chooses more advanced video capture chipset--XL series rather than FUSION 878A. This new chipset compensates or overcomes many defects of FUSION 878A and has a superior capability. For software, by adopting the most advanced ultrahigh frequency video transferring technology, single Ether8000 chipset can reach up to 30fps (frame per second). This high usage of chipset lowers the cost of hardware. In addition, in technologies dealing with the video it has many advantages too. For example, high video resolution, no sawtooth or interlace on moving objects, independent color adjustment of four channels (connected to one chipset) by software. Other capabilities and functionalities are complete with stability. Ether8000 DVR use MPEG-4 compression mode with great networking effects, and it supports remote view and control by Internet Explorer. It's defect is that it only supports Windows 2000 Professional/Server/XP rather than Windows 98. This brings discomfort to some users, but it's said that that is a method to compel users to choose stable Windows 2000 OS for a better performance. 

C) PICASO from Korea belongs to early catagory too. It was popular inside China about one year ago. But due to rapid development in computing technology, compared with new generation DVR products, PICASO seems to be behindhand. Opposite to Ether8000, it supports only Windows 98 OS but not Windows 2000. That's because PICASO was developed before Windows 2000 came out. Other aspects are that it's captious to mainboard and display card, complicated to install, high harddishk usage because of M-JPEG compression mode and ill network capacity.

D) KODICOM from Korea has been widely used inside China until present. It is superior to PICASO in many aspects. But its compression mode is not advanced enough with high harddisk usage. When connected to 8 channels, KODICOM and PICO2000 have the same problem in video jittering because of backward video transferring technology. It also faces the future of being replaced by new generation DVR software--Ether8000 series.
