Datapath 1 HD, 1 HD-SDI & 1 SD Capture Card

Manufacturer Datapath

Request more information or contact us now for purchasing information.


Product Overview

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 time stamping with all video capture channels.

This half length full height card features a full mechanical sixteen 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 the SDI signal, which can be sychronised with the respective video channel. This card provides balanced and unbalanced analog audio capture, through an optional audio module (the Datapath AM2)

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