Epiphan AV.IO SDI+ USB Portable Capture Card

Product Overview

The Epiphan AV.io SDI+ is a portable SDI to USB capture card that brings 3G-SDI video and audio into a computer over USB 3.0. Designed for AV professionals and integrators who capture from BNC-equipped cameras, switchers, and audio mixers, it delivers 1080p video to any application that accepts a USB video source. It is a compact, durable SDI USB capture card for live streaming, recording, and conferencing on Windows, macOS, and Linux.

Product Description

The AV.io SDI+ takes video and audio from BNC-compatible SDI cameras and mixers and captures it through a USB 3.0 connection. One BNC input accepts a 3G-SDI signal and one 3.5mm TRS input accepts analog stereo audio from a mixer or external source, while the USB Type-B output delivers up to 1080p video to your computer. The card automatically adjusts the image based on the software in use, maintaining quality even when sources are swapped.

The card is powered over its USB Type-B connection and draws only 250 mA, so no external power supply is needed. It is compatible with Zoom, Microsoft Teams, Wirecast, OBS, and any other program that accepts USB as a video source. Its ultracompact metal housing and single LED status indicator make it well suited to mobile kits and fixed installations alike.

For HDMI sources, compare the AV.io 4K and the AV.io HD+. For internal PCIe SDI and DVI capture, see the DVI2PCIe Duo in the Epiphan collection.
