Red-light cameras certainly are legal in some cities

Q. Recently my friend received a “courtesy notice” from the Garden Grove Police Department. Enclosed were a few photos of his vehicle at an intersection. It stated they want him to make an appointment to view the video of his vehicle going 15 mph through a red light. Are photo-enforcement pictures allowed as a way of giving someone a traffic citation? Is this legal to do at intersections?
