5, support for hardware arbitrary windowing, secondary scaling, hardware flip;
6, similar to the function of the memory mapping, multiple applications/processes can be **** to enjoy the acquisition of its image data;
7, the hardware control of the frame rate of traffic, the actual use of the card and other capture cards with In use and other capture cards with more effective increase in bandwidth utilization;
8, support for RGB32, RGB24, YUV422, RGB8 and other capture formats;
9, brightness, saturation, contrast, a variety of parameters can be adjusted;
10, to provide a wealth of secondary development packages;
11, excellent workmanship, the whole series of The use of environmentally friendly materials and some imported components to ensure the stability of the product.
Product Advantages

2, HD mode: can be collected 1080P, 720P, 586P, 480P progressive digital signals;
3, high point frequency: the direct use of high-performance acquisition chip, point frequency of up to 220M, the market in the early 21st century, very few manufacturers to achieve;
4, high transfer rate: the use of PCI - E Express X4 bus architecture design. E Express X4 bus architecture design, compatible with X8, X16 transmission rate is higher;
5, high bandwidth utilization: unique hardware bandwidth utilization technology, so that the PCI-E bus to get a real sense of effective use;
6, MICROVISION own technology, no signal when the blue screen, crash;
7, full-automatic line Field Frequency Detection: fully automatic line field frequency adaptive capability and signal self-detection capability, the source side of the signal changes do not require user adjustment, fully suitable for unattended applications;
8, the use of standard WDM, VFW driver, support for the development of the standard Directshow, to provide a complete secondary development kit SDK, but also to provide a secondary development kit demo program based on VC, VB, Delphi, etc., and the second development kit demo program and Delphi, etc., the second development kit demo program.
9, you can use Microsoft's AmCap, VidCap, Windows Media Encode, Window Movie Maker, third-party applications such as LabView;
10, good compatibility: support for most of the majority of video conferencing software, video surveillance software, P2P software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software, video surveillance software and so on.
10, good compatibility: support for most of the domestic video conferencing software, video surveillance software, P2P capture terminal software, live software.
