In today's fast moving World, the accidents are increasing at a very fast rate. One of the major causes of these accidents is over a speeding of vehicles. A major step has been taken rather to increase the road safety, so as to minimize the accidents .One of a major development was the introduction of speed cameras. This camera, usually containing radar, is electronic devices those working are still a mystery to most electronic hobbyists. The principle of these speed cameras is Doppler Effect used in radar. Now we would like to believe that enforcement cameras are there for our on good and make our roads safer. In general speed camera are perceived to be good idea because they protect innocent road users and pedestrians. Although these cameras reduces accidents and protects the innocent road users, the way in which the speed cameras are currently used is not to make the driver slow down, obey the speed limit and make the road safe but to catch and penalize the transgressors who may otherwise have slowed down if they have seen as the cameras in advance .i.e. speed camera , as, currently deployed, are not so justifiable
