Razor Multi-Channel USB 3.0 Streaming & Capture Dongle

Stream and Record

The Captiva® Razor uses a USB connector to interface between your camera/microphone and a laptop or desktop to stream and record. It’s the perfect portable video tool for events, lectures, live or on-demand executive broadcasts, school morning announcements, webinars, and online training.

With Razor and encoding software, like Streamsie® or OBS, you can deliver HD content from any location with an Internet, WiFI or Cellular connection. Just plug in your camera and mic into Razor, connect Razor to your computer, and start streaming and recording.

USB 3.0 Interface

Razor is self-contained and directly powered from the USB 3.0 interface.

USB 3.0 normally does not have enough bandwidth to process HD video, however Razor compresses the video before sending it to your PC, allowing you to use a USB interface. You can easily do a live dual-channel video shoot with small mobile equipment.
