This is a standard PCIe capture card — it works on its own in any Windows or Linux PC. A VSN wall controller chassis is only needed if you're building a multi-display video wall; most of our capture cards are sold and used as standalone cards in a single workstation.

About This Product
A capture card with three independent channels — two supporting HD capture (3G SDI, DVI) and a third supporting SD composite video — all captured simultaneously. The XtremeAV-SDI adds multiple channels of audio capture that can be synchronised in software using timestamping across all video channels, including embedded audio from the SDI signal.
The half-length, full-height card features a full mechanical 16-lane connector with notches that fit 4, 8 and 16-lane motherboard slots, providing balanced and unbalanced analogue capture through an optional EMS AM2 audio module. A single flexible card solution for medical, lecture capture, webcasting and video conferencing applications.
Where This Product Fits
XtremeAV-SDI is the fit when a single card needs to mix HD SDI/DVI capture with one SD composite channel and full multi-channel audio, synchronised in software — common in medical and lecture capture rigs pairing a modern SDI camera with a legacy SD monitoring feed. If every channel needs to be full HD rather than a mixed SD/HD layout, compare against XtremeDV-SDI4 for four-channel pure SDI capture; for a two-channel HDMI-only card at lower cost, see XtremeAV-HD2+.
