The VisionAV-SDI is a four lane PCI Express card with three video capture inputs - two supporting HD capture and a third supporting SD composite video, these three independent video channels can be captured simultaneously. The VisionAV-SDI also adds multiple channels of audio capture, which can be synchronised in software using timestamping with all video capture channels.

The half length full height card features a full mechanical 16 lane connector with notches which will enable it to fit four, eight and 16 lane motherboard connectors.

The VisionAV-SDI also adds embedded audio capture from SDI signal, which can be synchronised with the respective video channel. This card provides balanced and unbalanced analogue capture, through an optional audio module (the Datapath AM2)

This capture card provides a single flexible card solution for areas such as medical, lecture capture, web casting and video conferencing.
