Fast, low latency ip (or analog?) camera for RV reversing camera

I have a 1973 GMC motorhome that I am fitting out right now. I am going all home assistant on it, to the point of having a couple of cameras (rear and front) streaming to an IPad up front. I’d like to use an ip camera at the rear but am concerned about latency. Even 1-2 seconds would be jarring.

Can anyone recommend some low latency (as in video encoding) ip cameras which would work as a reversing camera?
