Vehicle activated signs with face (your speed sign with face)

Short Description:

The GUANGAN’s radar is a ground-up development by using the latest power saving radar technology. When the vehicle drive into the radar detection area (about 100 meter in the front of radar sign), the microwave radar will automatically detect the speed of the vehicle and the speed will be displayed in the sign to remind the driver to reduce driving speed, which Effectively reduce the road traffic accidents caused by high speed driving. Speed feedback device has a significant eye-catching induction driving function, can significantly reduce traffic accidents, to achieve safety guidance. This helps deliver market leading radar performance while maintaining extremely low power usage, this furnishes the radar with a full multi-target acquisition platform, accurate range measurement, and adjustable output rate of targets.
