The speed humps camera, an electronic traffic surveillance instrument, is a matter of concern for most drivers. Traffic agencies use this technology to control the speed of circulation of vehicles to curb excess speed on roads, streets, and highways. There are four types of radars: fixed, static, mobile, and portable. Each of them measures the speed of a vehicle in a specific way.

Types Of Speed ​​Radar And How They Work

There are four types of vehicle speed meters. Speed ​​cameras differ in their shape and mode of operation. Depending on the type, they can be used by a traffic agent or installed on highways, but all have the function of identifying when a vehicle exceeds the maximum speed allowed for the location.

  • The fixed radar, also known as a sparrow, does not demand that the transit agent operate since it is installed on the roads, usually the posts. When capturing speed, the fixed radar also records an image of the vehicle that is above speed.
  • The static radar is, like the fixed radar, equipment without mobility, installed in support of the vehicle. The difference between them is that the second is not installed on the road, but placed at specific points, often not visible, or on curves. This equipment also takes pictures of vehicles that exceed the maximum allowed speed. The Federal Highway Police (PRF) often uses it in special speed enforcement operations, such as during the end of the year and Carnival.
  • The mobile radar is also installed in a vehicle but works on the move. Therefore, to measure speed, the vehicle does not need to be stopped on the road. This equipment, however, does not record images.
  • The portable radar, in turn, must be operated manually by a traffic agent, who must direct it to the vehicle whose speed is to be measured. Like the previous one, this one also doesn’t record images.

Knowing the differences between the cameras used is extremely important if you decide to appeal a speeding ticket whose infringement has been detected by a surveillance device.

In any case, although there is no prediction of when or if the suspended radars will be used again for surveillance, you, the driver, must always be aware of the traffic, especially if you frequently drive within the city – where the use of radars is not prohibited.
