The radar speed sign is displayed digitally on the screen. When the vehicle speed is equal to or greater than the set limit speed, the display shows a red number to remind the driver to reduce the driving speed and pay attention to driving safety; when the vehicle speed is less than the set limit speed, the display shows a green number and the driver can drive normally

Radar working drawing:

The radar detection vehicle speed time is about 0.5s. So it can detection many cars at the same time.                                             Normally used at the place where needed lower driving speed such as exit of tunnel,ramp,construction area etc.
