Blind Spot Detection Sensor Aided Parking Sensor Point Blind Spot Detective System Millimeter Wave Radar Monitoring Change Lane Preface10/20/30/50m represents the maximum sensing range of the sensor, this item does not need to be punched in the body and does not damage the paint, suitable for any car Features: [-1-]:During the driving process, when the side or rear vehicle is in danger of collision with our vehicle, the LED lights will light up to remind the driver; if the left/right turn signal is turned on, it will be accompanied by an audible warning. [-2-]:Start to monitor the blind area when the car is started. When you open the door, if there are cars, pedestrians and motorcycles behind, they will be monitored and the alarm will be accurate. [-3-]:Our blind spot monitoring can distinguish between stationary objects and moving objects. Stationary objects will not alarm. Vehicles, pedestrians, bicycles and motorcycles in a driving state will sound an alarm when they are monitored. [-4-]:When waiting for traffic lights: After parking, the car behind will stand still, and no alarm will be issued in the blind area. [-5-]:Normal driving: When the car behind is slower than us, there is no danger of collision and there is no warning; similarly, when we overtake, the speed is faster than the car behind and there is no warning. Working principle: 1. The system is a vehicle auxiliary device that can help the driver to safely change lanes while driving. 2. Use a 24 GHz radio frequency sensor to detect the side/rear of the vehicle, and then move the object to the blind spot of the detection area. 3. The system acts as a control unit (LED computer), two microwave radar sensors, two blind spot monitors (or LED lights), buzzer and wiring harness, and is a perfect combination of microwave radar sensors and computers. 4. There are blind spots on the rearview mirror of the vehicle, which can easily endanger driving safety! After installing the BSM BSD millimeter wave radar on your car, as long as there is a moving object at the rear of the vehicle, the LED lights will flash regardless of day, night or in the snow. The sound signal reminds the driver to be careful when changing lanes to avoid the possibility of a side collision. Specifications: Voltage: 12 V. Maximum power: 5 W (maximum) Working temperature: -40 + 85 Waterproof rating: IP67K Detection range: lateral distance: 0.3m-4m; rear lateral distance: 0.3m-10m./20m Detection range accuracy: 96 Alarm range: 0.3m-10m/ 20m /30m /50m Alarm system accuracy: 96 Alarm method: Method 1 =< The LED lights up. Method 2 =< The LED flashes and beeps. The package: Microwave sensor *2 LED light *2 Main wire harness with buzzer *1 Extension of sensor cable *1 Extension of LED *2 Black tie band *20 704 Silicon glue *1 Double-side sticker of LED *2 Double-side sticker of buzzer *1 Bevel protractor *1 Manual *1 Suggestion: 1. It is recommended that the installation be carried out by professionals. 2. The installation angle of radar will affect the detection distance and effect. Please install it strictly according to the instructions. 3. Rainstorm weather may affect the detection distance and effect. 4. Moving objects approaching 3M behind the vehicle may not be monitored. 5. Because of manual measurement, there may be a change of 1-3 mm (cm). Note: 1.Transition: 1cm=10mm=0.39inch 2.Please allow 0-3cm error due to manual measurement. pls make sure you do not mind before you bid. 3.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
