Product Packaging Main components:2 millimeter wave radar probes, 2 LED lights, 1 buzzer Accessories: 1 package of screw and tie-up, 1 wires, 1 Instructions, 1 auxiliary card for installation2 brackets Working Principle 1. The system is a vehicle auxiliary equipment, which can help drivers safely change lanes while driving. 2. Use the 24 GHz RF sensor to detect the side/rear of the vehicle and move the object to the blind spot in the detection area. 3. The system acts as a control unit (LED computer), two microwave radar sensors, two blind area monitors (or LED lights), a buzzer and a wiring harness, which is the perfect combination of microwave radar sensors and computers. 4. Vehicle rearview mirrors have blind spots, which can easily endanger driving safety! When BSM BSD millimeter wave radar is installed in your car, as long as there are moving objects in the rear of the vehicle, the LED lights will flash, no matter in the day, night or even in the snow. The sound signal reminds the driver to be careful when changing lanes to avoid the possibility of side collision. Functional characteristics 1. In the course of driving, when the side/rear vehicle has collision risk to our vehicle, the LED light will light up to prompt the driver; if the left/right steering light is turned on, it will also be accompanied by sound warning. 2. Our blind area monitoring can distinguish stationary and moving objects. Fixed objects do not alarm. Vehicles, pedestrians, bicycles and motorcycles in moving state will have alarms when they are monitored. 3. Blind zone monitoring starts when the car starts. When you open the door, if there are cars, pedestrians and motorcycles in the rear, they will be monitored and the alarm will be accurate. 4. When waiting for traffic lights: the rear car is stationary after stopping, and the blind area will not alarm. 5. Normal driving: when the rear car is slower than us, there is no danger of collision, no alarm; similarly, when we overtake, the speed is faster than the rear car, no alarm. Characteristics 100% original factory, quality assurance! Type:Millimeter Wave Radar Blind Zone Monitoring Vehicle Lane Change AssistanceBSD BSM) Voltage: 12 V. Maximum power: 5 W (maximum) Working temperature: -40 + 85 Storage temperature: -40 + 85 Waterproof rating: IP67K Detection range: lateral distance: 0.3m-4m; rear lateral distance: 0.3m-10m. Detection range accuracy: 96 Alarm range: 0.3m-10m Alarm system accuracy: 96 Alarm method: Method 1 =< The LED lights up. Method 2 =< The LED flashes and beeps. Note 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). Why did you choose us? 1. We are a manufacturer.

The sooner you knowthe rear side of the car, the more you canRespond in time, safely BSD blind spot monitoring system When car A is driving, you can see car C from the rearview mirror,but you can see Less than car B, when car B enters the detectionarea, the alarm light will be on Working around the clock All-weather work is not affected by theweather, no fear of frost, rain, fog, etc. Full set of products Installation instructions Looks like: 1. Position the radar angle with the standard triangle, and adjust the angle with the short side parallel to the vehicle body or the tire leaning against the radar surface. 2. Adjust the correct angle to 20 degrees. The upper and lower mounting heights are 70-90cm 3. The main line linking the radar must face the inside. Radar probe installation parameter requirements 1Remove the rear bumper and determine the installation position of the radar probe module. The position is located at the arc of the rear bumper of the car. After drilling, the base of the probe bracket is installed. The angle and height are as shown in the figure below: the module is marked with the head facing up. *Note: The installation angle and height of the radar probe are very important. For the best experience, please install at the above height. The radar probe is vertical and must not be tilted to the ground. The left and right sides are inclined outward by 20 degrees. Please use
