1、4 Accurate Sensors: This car parking radar is equipped with 4 accurate sensors, which can measure obstacles within a range of 0.3 to 2.0 meters, providing you with accurate distance information during the reversing process. With the embedded design of X, Y, and 60 degrees multi angle, these sensors can ensure all around perception of the surrounding environment, helping you effectively avoid potential collisions caused by blind spots in your vision during the reversing process, thus improving driving security. 2、Innovative Voice Alert System: This vehicle reverse backup radar uses a unique 3 levels heartbeat alert tone with different sound frequencies to change the warning tone according to the distance of the obstacle behind, when the obstacle is getting closer, the warning tone will become more and more urgent, thus allowing you to more intuitively perceive the security distance behind you and avoid accidents such as rear end collisions. 3、2 Digits Display: This reverse backup sensors radar system has a 2 digits display and a colorful light bar function representing the direction, letting you know at a glance the exact distance of the obstacles behind you and the direction of their presence. Whether it's day or night, the clear display system can help you easily get all the information you need for backing up, guaranteeing a fluent and secure driving. 4、Easy To Install: This car parking sensor rear reversing radar comes with a detailed installation guide and requires a simple drilling operating to complete all the installation steps. The reversing radar is also provided with a 5 meters display cable length and a 2.5 meters sensor cable length, which ensures the flexibility and convenience of installing the device. 5、Excellent ABS Material: This car reverse parking radar is made of excellent ABS material, which has excellent anti impact and anti erosion properties, and can maintain stable working condition in various harsh environments. Meanwhile, it has a wide range of working voltage (DC 9V‑15V, rated voltage DC 12V), which can ensure the normal operation of the device in various voltage environments, providing long term and reliable guard for your driving security.
