night time with cars going by is the worst area for a camera-- there is almost nothing you can do to get amazing pictures at night with headlights around you.
i think that ir is going to be useless for rear view cameras, in most cases, a bullet camera should work fine, and would be easier to mount.
in a city area, the ir is just going to bounce of the surrounding cars, complicating the problem of not being able to see.
also, i have not been convinced that ir on a car is that best idea-- at least when there is any visible light to the naked eye (people pass you wondering why your mirrors are glowing red...distracting them from the road). if you can use higher quality ir led's that are not human eye visible, it should take care of that problem(though they're not cheap).
then there is the lens--so far, auto iris lenses do best at changing contrasts(at night, as headlights sweep across view), simply becaue they block out the light that is not needed. the problem though is that these are large and bulky compared to auto contrast cameras like what you posted above. but auto contrast cameras always have the same amount of light going into the lens, and the camera chip/
software compensates. auto iris lenses physically change the amount of light going into the lens to correct the problem.
for my own car, i would go with 3/4 bullet cameras with about a 3mm lens, which is relativly wide angle, but will give great coverage.
