Camera generated tickets have been argued in court many times. We have the right to face our accuser. No camera has ever testified in court.
I think the state or city is the accuser, the photo is just the evidence.
Would the accused be able to subpoena the installer to ask how they guarantee the camera functions properly?
I guess if you'd like to take it that far, you could.
That would be the same as sending a subpoena to the guy who made a radar unit to explain it was working properly when you got a speeding ticket.
If you have enough money, you can appeal anything up the ladder of courts. Lawyers love that!
