I looked at the "Device and System Configuration" where they suggest a camera like an go pro.
I have not been able to test this. But I see youtube video's where an Go Pro is on live view mode connected to a HDMI monitor with massive lag.
Anybody have any experience with this?  In the end I want to buy an Go Pro 7 Black with an HD60Pro capture card. I want obviously no delays in one of the camera's/
