Sure, that is the purpose of this product :)
You can also read in other HDMI signals, but since many signals are protected with HDCP, this does not work. However, it is possible to feed in camera streams without any problems.
The video input is recognised as a normal 1080p webcam stream, even with audio.
What I have to mention in a negative way is the picture quality: The picture is slightly oversaturated (very colourful), so the picture is not fed in natively, it is still "optimised". I would prefer an adapter without optimisation. But it's individual and therefore I will probably be the only one who is bothered by it.
Of course, the price/performance ratio is great.
