Model 811 is a PCI-Express 4-channel frame/video capture device designed for applications requiring a high capture rate from multiple input video channels.

It supports capturing from NTSC, PAL, SECAM, RS-170, and CCIR video sources.


The Model 811 provides four channels of stereo or mono audio capture associated with the four channels of video respectively.

For each video channel, the frame capture rate is up to 30 fps for NTSC and 25 fps for PAL.

The total frame/video capturing rate up to 120 fps for NTSC and 100 fps for PAL.


The 811 supports the following capture resolutions: D1.N (NTSC), D1.P (PAL), VGA, QVGA, QQVGA, SIF, 2SIF, 4SIF, CIF, QCIF, SQCIF, 4CIF.


Associated with each channel, general digital I/O signals are also provided for control or trigger purposes.


A single +5V power supply through the PCI express bus is required to power the board.


Model 811 implements a single-lane (x1) PCI Express interface. It can be plugged into a PCI Express slot of any width.

Software and Manuals
The 811 is supplied with a software developerís kit, SDK811. It includes drivers for Windows XP/Vista. A Linux driver for kernel 2.6 is also supplied. Each kit includes sample application programs.
