Microwave radar-BSD (77G)

This BSD (blind spot detection) system is used for detecting the objects in the blind area of the rear and side field of the vehicle when you are driving. When a vehicle (or other moving object) enters into the detection range, the BSD system will alert the driver with LED light blinking or/and Buzzer sound beeping to let the driver knows the safe timing for lane change and reversing, thus significantly lower the potential risks of collision accidents and save lives. It can also be applied for the purpose of vandalproof and antiriot for safeguard when you stay in a car.
