Connect two HDMI feeds to the IPMAN Gemini Pro HDMI to USB converter from Z CAM to send them simultaneously to a macOS or Windows computer via its USB Type-C connector. The IPMAN Gemini Pro supports HDMI signals up to 4K30, as well as 1080p60 and 720p60, converting them to 1080p30. Connect the converter's output to your computer, which recognizes the device as a USB camera, for plug-and-play connectivity with no drivers to install on macOS or Windows. You can use OBS or virtually any other streaming software on your Mac or Windows system to simultaneously view both HDMI feeds.
The IPMAN Gemini Pro is recognized as a USB camera by Windows and macOS computers without needing to install drivers on your computer to make it work.
