You've got a straight shot at both doors from that angle. The question is more along the lines of how far out from the first door do you need to record? 2.8 would be good on angle but lousy for ID. 6mm would be best for ID at the second door but limit how from out from the house you'd get coverage, particularly in front of the first door. Best coverage would be two cams, either 3.6-4 mm or 6mm and possibly mount them both between the two doors and angled away from each other. You'd have a significant blind corridor in the middle with 6mm lenses doing it that way though. You could mount them to the outside of each door and cross the coverage towards the middle as well and that would cover traffic approaching from between the two doors much better.
