I would first vote out your governor...
Grant it I do not agree that an officer need to be present, this gets rid of the hearsay issue when you try to fight it in court. But it looks like they were attempting to make sure all the camera systems operated the same way across the state so each local government did not do their own thing and get rid of the revenue sharing issue.
PA has a very good statute on the books for red-light cameras, it is the longest and most thorough of the rules of the roads sub-chapters PA has. It explains exactly how it must be done, the traffic studies that are required and how the light and cameras must be set up. These are set up on Phily which I have seen people run a light 2 or 3 seconds after my light turn green. Those people just ignore all the traffic signs so anything there is an improvement.
So vote the guy out and get your local rep to put the law throw again. And you can attempt to fight it on the hearsay issue, since you do have a right to confront your accuser which in this case is a camera.
