Dash cam controlled from Android radio

[misiolud]

Hello,
I'm planning to purchase an Android radio and a Dash cam. I learned that the radio is able to act as a "brain" for dash cam if appropriate camera is attached to it via USB.
I noticed that those cameras do not have a display e.g. https://www.joyingauto.com/joying-newest-dvr-front-dash-camera-with-720p.html so I understand they are actually like simple web cameras.
Do you consider them dash cams as well? I could not find any reviews of such units here.

Do you think it is possible to purchase such a camera with some decent optics/processor. Something comparable to https://dashcamtalk.com/sg9663dc/
Preferably it should also have a rear camera.

Thanks in advance
kind regards
misiolud

you won't get something like that to interface with a generic Android head unit
