Just use a regular mouse/kbd to set it up.
But as said, there are already many multi cam setups, that save to their own internal SD or microSD card.
2-3-4 cameras each.
I have a 2 camera setup in my 23 year old truck. Controlled by its own on-off switch, works seamlessly.
I just have a real heatrache about extra touchscreens and electronics in cars while driving, due to the demise of my former vehicle.
