I am a CA attorney. Go online and check with the court's website about paying for tickets online. Calling a local traffic attorney might be useful.
There are class action lawsuits against these red light cameras arguing that they are unconstitutional. You did not put where you are in Florida, but do Internet search for class action red light cameras in FL. A Miami Judge ruled they were unconstitutional recently for Miami-Dade County. Last I heard, which has been awhile is to pay for the fine then contact one of these class action attorneys. Please click on the website, it does not cost anything. Thank you.
