1、Broad Detection Range: With a significant detection range of 0.3 ‑ 2.0M, the car reverse radar system can precisely identify and measure the distance to obstacles. This drastically reduces blind spots when reversing, ensuring a safe and accurate park. 2、Visual and Auditory Alerts: The rearview mirror LCD screen clearly displays the reversing distance. Meanwhile, color warning lights and three levels of beeping sounds will timely warn you as the distance changes, providing convenient and efficient safety use. 3、Easy Installation Process: The sensor employs a drill in installation method, which is easy to operate and install. The kit contains four sensors that can be adjusted as per requirement, accommodating different vehicle types. 4、Broad Compatibility: The radar system is compatible with various vehicle types, from sedans and SUVs to commercial cars. With a working voltage range of DC 9V‑15V, it fits the electrical system of a wide array of vehicles, ensuring a safer driving experience. 5、Long Lasting Durability: Constructed with ABS material resistant to harsh environments. Also, sensor and display wires are adequately long, which not only ensures the durability but also facilitates the installation process.
