Rolling Right Turn Ticket ?

Here is a question from an email l received and would like your help answering . . .

I got a red light ticket in Orange County Ca, for a rolling right turn. The signs say "photo enforced" but the star witness is the video that they have. The photos that they send you in the ticket doesn't prove you didn't make a fast stop in between the photos. Has anyone ever used this defense that has emailed you...that the signs are incorrect because California VC 21455.5 (a) (1) says Identifies the system by signs......etc. How is "Photo enforced" Identifying a video system. Any feedback would be helpful..thanks
