There are too many monitors in the car, the driver can't view all the information in a short time, but it becomes cumbersome. Our products are only sound prompts, more practical, avoid trouble, and keep the car clean and tidy. Do not install the rear radar in the front of the car!What is the difference between front radar and rear radar? Difference 1: The professional front radar can still work for about 10 seconds after the power is turned off, helping the driver to safely pass through the narrow road. As shown below: At position 2, the driver has released the brakes, and the radar is powered off at this time, but it can still work for about 10 seconds to detect obstacles. Difference 2: Professional front-end radar, the longest detection distance is: 4FT, when waiting for a red light, it will not detect the car in front of the car and generate an alarm. When waiting for a red light, we know the safety distance of the car in front of us, and we do not need to call the police. For example, too many alarms will not only affect driving safety, but also make people upset! Difference 3: Most of the sensors in the front of the car are installed at a lower height than the rear. Therefore, professional front-end radars adjust the sensitivity of the sensors to prevent the ground from being detected and false alarms. If the rear parking radar is installed in front of the car, it will detect the ground and generate random reports, which has no effect. Professional front radar VS rear radar Front radar: When braking, the sensor starts to work. When it detects obstacles, the system starts to alarm; when the brake is released, the main power of the system is disconnected. At this time, the main board capacitor discharges the power, and the sensor continues to scan for 10 seconds and then stops. In order to make the driver turn or change lanes in small places, release the brakes, and get the warning of the parking sensor during the refueling process. Finally, the above two functions, the rear parking sensor does not have this function. Smart start When braking, if the obstacles are not activated, the user-friendly design avoids the troubles caused by the endless starting system. Product parameters 1
