Radar Speed Signs are those devices which are used to detect the moving speed of the vehicle and display it on the screen making the driver aware of his speed. If the vehicle is at a speed greater than the permissible limits, it warns the driver and asks to slow down to a speed which is permissible in the specific zone. These devices have a detector that detects the speed of an incoming vehicle from a distance and a display unit which displays the permissible speed limits in the area and the actual speed of the vehicle.
The Radar Speed Signs by Houston System are very efficient in detecting the exact speed of the vehicle and displays it instantly on the screen with minimum time lag. The HouSys Radar Speed Sign also has provisions to videotape the vehicle whose speed is above the permissible limit as a proof of violation done by the driver. The tape gets stored in the server of the central command center and can be accessed to frame charges on the driver.
