Suppose two cameras were installed x distance apart from each other in a hallway. They were placed directly across from each other in circular casings. The first camera is in a small casing that is about 3 times as small (1/3 the radius) as the bigger casing for the other camera which limits its viewing angle. The distance between the two cameras is such that the max they can see horzontally is the widest point on the other camera's casing. If you were to draw lines of the max viewing area from each camera to the casings of the other camera, the lines would intersect their own casings. Which camera would have the greater distance between its own intersections (intersection to intersection) at its casings.
