What about those intersections with one way traffic that only have one camera installed instead of two?

It doesn't photograph your front plate - there are two pictures taken of your rear plate.

The end result is, if you run a red ticket will show 2 pictures: the first one shows the vehicle crossing the second white line when the light is red, and the second picture shows the vehicle in the middle of the intersection also with a red light.
