Speeding would require the police to record/archive video, vs. just a single photo which contains both your car being behind the white line and the red light.
Also, the red light ticketing programs are often administered by private companies, without officers being involved. Speeding ticket video would need to recorded by the police.
All that said, I think its a great idea and the obstacles can surely be worked out.
Finally, a tip: if you are ever pulled over and you plan to dispute the arrest, request the officer's dashboard video ASAP. This will ensure it is preserved and available for you at trial; if you don't request it quickly enough it might not be available when you do. Don't count on it being around even a week - request it the very next day.
