The usb is only half the story, because the full resolution doesn't go out there. A 4K from Elgato together would be a good solution via hdmi.

Hi Mimo77,

you can connect a computer etc. to the camera via a USB cable and use the camera's video and audio function for live streaming or web conferencing services.

Sony Support EN

All you need is a USB (mainly C) cable and, if necessary, Sony's software, which you can download and use free of charge.
