Blind Spot Detection (BSD) is a technology that alerts drivers to objects that may have been in the driver’s blind spot.
The system uses sensors to detect when a car is in the driver’s blind spot. It will then warn the driver with an audible alert, and sometimes a visual alert, if something is detected.

1.what the blind area for car and truck?
1.1 car blind area
A car mirror blind spot is an area on each side of your car that cannot be seen in either the internal rear view mirror or both side mirrors.
we find a site write good content about car blind area.
1.2 truck blind area
Truck blind area is a critical area of a truck that needs special attention. This is the area behind the truck where people and objects are not visible. This is where most accidents happen. The blind area is also the area where the truck driver has the least amount of control.
So what can be done to reduce the truck blind area?
1. Make sure the truck has good visibility. Make sure the truck has good lighting and clear windows. This will help the driver see the road and the objects around the truck.
2. Make sure the truck has good barriers. barriers can be made of metal or plastic. They should be high enough.
2.Does blind-spot monitoring prevent accidents?
NO,it can’t prevent accidents,but can give a alarm to driver.
Blind-spot monitoring is designed to help drivers avoid accidents. The system works by alerting the driver of any vehicles that may be in their blind spot and prompting them to check the side mirrors or turn their head.
Blind spot monitoring is a safety feature that has been around for years. It alerts the driver if there is another vehicle in their blind spot, but does not prevent an accident from happening. Blind-spot monitoring can be helpful for drivers to avoid potential crashes by warning them of other vehicles in their blind spot.
3.how many kind of BSD in the market?
There are a few different ways that blind spot detection works, but all of them involve detecting objects or people that are in the driver’s blind spot.
1.ultrasonic sensors,
2.Millimeter wave radar,
3.cameras.
4.BSD camera kit
3.1 ultrasonic sensors
Ultrasonic sensors are another type of blind spot detection that is used in some cars. They use sound waves to detect objects around the car. The problem with ultrasonic sensors is that they can’t detect objects that are in the driver’s blind spot. This means that if there is someone in the driver’s blind spot, they will be able to get hit by the car.
Ultrasonic radar sends out ultrasonic waves through the ultrasonic transmitter, and then uses the time difference of the reflected ultrasonic waves to be received by the receiver to measure the distance.
Generally speaking, the higher the frequency, the higher the sensitivity, and the smaller the detection angle in the horizontal and vertical directions (use range: 40KHz/48KHz/58KHz).
Ultrasonic radar is easily affected by weather conditions. The propagation speed of different weather is different, and the error is large when the vehicle speed is fast. In addition, the ultrasonic scattering angle is large, which is not conducive to the propagation of recovery signals in long distances; but it also has low cost and strong penetration. , waterproof, dustproof and other advantages.
you can get more details information and principle of how ultrasonic works.
3.2 Millimeter wave radar
Millimeter wave radar is the most common type of spot detection used in cars. It uses electromagnetic waves to detect objects around the vehicle. The problem with radar is that it can only detect objects that are close to the car. This means that if there is someone in the blind driver’s seat, the radar will not detect it. Millimeter wave radar is a radar that works with millimeter waves (Use range: frequency range 30-300 GHz, wavelength 1-10 mm). Millimeter wave length is between microwaves and centimeter wave, so millimeter wave radar has both microwave radar and photoelectric radar. The principle of telemetry is to transmit radio waves (radar waves / electronic waves), and measure the target position data based on the time difference between the echoes received in the air.
The general detection range is between 0 and 200 meters. Compared to optical seekers such as infrared, laser and TV, the millimeter wave seeker has a strong ability to penetrate clouds, smoke and dust, and can withstand all weather conditions (except extreme rain) all day. The anti-interference and anti-theft properties of the millimeter wave detector are also higher than other microwave detectors. However, the attenuation of millimeter wave radar in high humidity environments such as rain, fog and snow, as well as the effect of high power devices and insertion loss, will reduce the detection distance of millimeter wave radar; Low input; high cost of equipment, very high processing speed, and slow development of single-chip transceiver IC, which will be used in addition to the camera.
3.3 Cameras
Cameras are another form of blind spot detection used in some vehicles. They use the camera to find out what’s around the car. and use the AI Chipset to detect people and moving objects and when you find people or objects moving in the detection area, the alarm will give the driver a sound like “didi” and also display and monitor , BTW, we can also use extender. speaker to remind people “it’s dangerous, please leave for the car”.
The BSD camera will not be affected easily, because you need to install the camera in a high place, and not far away, only if your camera can capture, it can help you identify people and things move to the discovery area, for BSD systems, it supports setting the detection point, but BSD cameras do not support it.
3.4 4CH BSD camera kit
This 4CH BSD camera kit have 4ch BSD detect function,chipset is based in the monitor, can use the universal camera,when camera capture people or moving object ,will give a alarm to driver and the people outside.
This system can adjust detect area on the monitor,and other optional function like 8ch view,4G,GPS,WIFI etc.
4.How does BSD work?
BSD is part of a car’s safety system that detects when the driver is unable to see objects in their field of vision.
With blind spot detection, its sensor watches where you can’t see. The technology closely monitors vehicles as they approach you from the side or rear.
The AI chipset will try to help the drive to figure out the people and moving object around the vehicle ,help to located the people and give a warning infromation to the driver.
Blind spot detection is a key technology among driver aids that provides 360-degree electronic coverage around your vehicle whether you’re speeding or slowing down. This safety environment also includes adaptive cruise control, lane departure warning, rear and front parking sonar, rear cross-traffic alert and parking camera.
Some driving aids make you safer, especially in the long run, and some pay for themselves when you don’t damage the insurance, while the insurance costs more than the device.
5.how to install the blind spot senor ?
Cus there are different product ,and they have different install method,but best way is find some professional install company to help with you,this company write a nice a article about some advice for it .
This site will give some advice on how to install the senor.
6.what to do if blind spot detection not working?
There is lot of reason why your blind spot detection is not working ,you maybe get some idea from this place ,can be some of this reason
1. cable unplgin
2. some thing cover the surface of the sensor
3.senor broked
4. senor is ok ,but your monitor broked.
you can do something try to figure out what the excat reason.
