BY-J Blind Spot Monitor System
Professionally provides vehicle assistance device that helps you detect the possible collision risks in the blind spot during driving.


The rearview mirrors on both sides of the car can only see both sides of the car body, and cannot fully collect all the information around the car body, especially from the main road on the auxiliary road. The left rearview mirror cannot observe the vehicle. If you accelerate and cut into the inner lane at a large angle , Easy to collide with a vehicle driving at a high speed in the inner lane.
Blind spot information systems are increasingly a "must-have" feature for large trucks and SUVs with long tail ends and poor rear visibility.
WARNING: Do not use the blind spot information system as a replacement for using the interior and exterior mirrors or looking over your shoulder before changing lanes. The blind spot information system is not a replacement for careful driving.
WARNING: The system may not operate properly during severe weather conditions, for example snow, ice, heavy rain and spray. Always drive with due care and attention. Failure to take care may result in a crash.
NOTE: The system does not prevent contact with other vehicles. It is not designed to detect parked vehicles, pedestrians, animals or other infrastructures.
NOTE: The system may not alert you if a vehicle quickly passes through the detection zone.


Long Range Detection
The detection range is 12 meters. The sooner you get to know the back of the car, the better you can respond in a timely and safe manner.

BSD Blind Spot Monitoring System
When the A car is driving, the B car is seen from the rearview mirror, but the C car is not visible. If the A car changes to the left lane at this time, it is easy to collide with the C car!
