How a Speed Camera Works
Ticketing
A car will run over electric sensors which are placed in the ground. This will set off a timer in the clock. When the timer runs out, the picture is taken. If the car is traveling at a normal speed, it will not be in the picture. The film is then processed and sent digitally to the police department. At that point, each picture has to physically inspect by an officer to verify an infraction took place. They check to make sure the camera didn't pick up a driver who was moving too slowly and that the camera was functioning properly. Once they have ascertained that an infraction has taken place, a ticket is issued and is sent with the picture to the owner of the car.
Accuracy
Usually the cameras are very noticeable. They are placed in brightly colored housings so motorists can see where they are and adjust their speed accordingly. Used in this fashion, they are more of a deterrent to speeding than an actual enforcement tool. However, if a motorist is speeding, they will be caught by the cameras. They are highly accurate machines and are able to take a reading from a side mirror and a license plate, which means an innocent driver will not trigger the camera by mistake and a guilty one cannot claim it was someone next to them who was actually doing the speeding. They can work in any light or weather condition and self test after every picture to maintain accuracy.
