You have to prove that your guilt was not "beyond reasonable doubt". meaning you are close to 50% chance of being right.
Chance of 相机不准，或Mal-functioning, is: Possible but not probable, and where is your evidence that "相机不准，或Mal-functioning"? You cannot make allegation without facts. Without more evidence, and merely based on your own testimony, that " I am always a very careful driver", your argument probably will fail.
You could try driving school.
