sUAS Image Broadcast

This article demonstrates how to easily and affordably broadcast a live image from an in-air UAV, to virtually anywhere.



Using a small inexpensive video capture box, the HDMI signal between the sUAS controller and a secondary monitor is captured. A standard USB output on the capture box is then connected to a computer, where it is essentially being recognized as a secondary web camera. As a web camera, this signal can be used in any web conference client, such as Microsoft Teams, Zoom, Cisco Webex, and others.

Equipment used:

  • MiraBox Capture, connected to laptop using USB (available online at $35)
  • 25' HDMI cable (connected from UAV image source to MiraBox
  • 3' HDMI cable (connected to an optional monitor)

Below are some images illustrating the setup:
