You don't go to court because it's what they call "masked". Basically, unless you're pulled over by a real cop, they can only fine you.
By the way, this is why people with CDLs, like myself, can't be fined by red light cameras. It's illegal (federally) to mask a traffic violation on a CDL. I've run a few red lights, got my picture taken, but that was the end. Not even a notice in the mail.
