During the driving proce, 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.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. 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.When waiting for ffic lights: Ar parking, the car behind will stand still, and no alarm will be iued in the blind area. 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 princle: 1. The system is a vehicle auxiliary device that can help the driver to safely changees while driving. 2. Use a 24 GHz radio frequency r to detect the side/rear of the vehicle, and then move the object to the blind spot of the area. 3. The system acts as a control unit (LED computer), two microwave rs, two blind spot monitors (or LED lights), and wiring harne, and is a perfect combisnation of microwave rs and computers.4. There are blind spots on the rearview mirror of the vehicle, which can easily endanger driving safety! Ar installing the BSM BSD millimeter wave on your car, as as there is a moving object at the rear of the vehicle, the LED lights will f regardle of day, night or in the snow. The sound signal reminds the driver to be careful when changinges to avoid thepoibility of a side collision.Specifications:Working voltage:12VWorking frequency band:24GhzWorking temperature:-40℃~ +85℃Power consumption: le than 2WWater-proof level:67Distance resolution:0.5mRange accuracy:rior to 0.18m distance:20mnsceiving : single sending and single receiving : Infineon : GDBlothe thirde: NoSame speed follow warning: NoB-ar warning: NoBSD blind spot monitoring: √ (power on)LCAe change aist: √ (power-on start)AOA overtaking warning: NoRCTA warning: NoColour: blackMaterial: ABSPackage Contents:2 x 24Ghz millimeter wave 1 x power Cable1 x Power extension Cable (5m)2 x Indicator extension cable (4m/bar)1 x Cable2 x Mounting bracket1 set x AcceoriesOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the ture a little different from the real thing.
