When you buy a speed camera you will be given a certificate from the company that describes about its calibration. The calibration is being done after every twelve months by the company that so there is little room for negligence.
When it comes to the use of the certificate it is only used when a court case is being there as checking of the certificate every time is not feasible. You will find hat the camera calibration is being used when some red light violations are there and court asks that the speed equipment the authorities have used to record the speed is good enough to perform the job of controlling the traffic or not. At the time of presentation only the certificate is considered as ample evidence to be presented in court and court accepts it as such.
