AVMatrix UC1118: Turn an SDI Camera Into a Plug-and-Play Webcam

The AVMatrix UC1118 is a 3G-SDI to USB-C uncompressed video capture device that lets a professional SDI camera appear on a computer as a standard webcam. It is the small dongle that bridges broadcast cameras and everyday software, with nothing to install and no power brick. For anyone who wants their good camera in OBS or Zoom, it is the simplest possible answer.

What UVC Capture Means

The UC1118 is UVC and UAC compliant, meaning it follows the USB Video Class and USB Audio Class standards that operating systems support natively. In plain terms, you plug it in and the computer immediately sees it as a webcam and microphone input, with no drivers to download. That is why it works out of the box with OBS, Zoom, Teams, Twitch, and virtually any app on Windows, macOS, and Linux. It captures uncompressed video up to 1080p60 with automatic input signal detection.

Power-Free and Portable

Because it is bus-powered over USB, drawing only about 3.5 W, the UC1118 needs no external adapter; the single USB cable carries both data and power. That makes it ideal for laptops and field kits where every extra cable and power outlet is a burden. A 3.5mm line input lets you add external audio alongside the SDI feed, and the device captures 2-channel 16-bit 48 kHz PCM audio.

Where the UC1118 Fits

The UC1118 is built for bringing SDI cameras into a laptop for streaming, live streaming to OBS, Zoom, or Teams, recording SDI sources, and webinars and remote production. Streamers, educators, and remote presenters choose it as a truly plug-and-play, power-free way to use a professional SDI camera with any software, while the HDMI-input UC1218 covers HDMI sources.
