## Description

Car Blind Spot Detection System Universal DC12V Car 24Ghz Blind Spot Monitoring Assistant Project specification Electricity Voltage：12V Maximum Power：5W(max) Working Temperature：-40℃ ～ +85℃ Storage Temperature：-40℃ ～ +85℃ Waterproof level：IP6K7K Detection Range： Lateral Distance: 0.3m-4m Rear side Distance: 0.3m-10m Detection Range Accuracy: ≥96％ Alarm Range: 1-32.8ft (0.3m-10m) System Alarm Accuracy：≥96％ Alarm method： 1. LED light up 2. LED flash and buzzer sound Installation notes (FAQs can be updated dynamically at Q&A). 1. The sensor detection area is radially extended, the maximum distance can reach 32.8ft (10 meters), about the length of 2 cars, giving the driver more reaction time. 2. The working principle of the product: if there is an object to enter the radar detection area at a speed greater than their own car, the detection system will issue warning. 3. NOTE! The installation of the sensors to maintain an inclination angle of 20 degrees (package included with the installation angle ruler). This product has been launched for more than 6 years, and optimized after several upgrades (Upgraded with Infineon chip to improve the accuracy of lane recognition), in sufficient economic premise, to provide the most practical blind spot detection system to assist safe driving. Please know the working principle before installation, familiar with the installation method, for better installation and use.

Review: I will admit, I was hesitant because the reviews are mixed but I decided to take a chance. I then kinda dreaded the install because I figured it would be difficult. It was not too difficult. I fished the cable that goes to the front of the vehicle with a wire and then pulled the cable through with minimal interior plastic removal. The ground had a terminal already attached to ground to the chassis. The power had a fuse insert I was able to plug into a vacant spot in my fuse block that had power when I turned the key on. Soldered and heat shrinked the left turn signal wire, right turn signal wire and reverse wire at the rear. I decided to tape the sensors on the inside of the rear bumper cover. I cleaned the inside of the bumper with brake cleaner and used 3M automotive double faced tape. I have used this before on car door moldings and it is very strong so I think this will hold well. I placed the warning lights right at the pillars and they are bright enough. Took a test drive and it worked perfectly. I could see the passing vehicle coming in my side mirror, just before it went into my blind spot the light came on and then stayed on until I could see it to my with my peripheral vision. The passenger side worked just the same. I am very pleased with this purchase and the performance of this system.
Review: I paid a fortune to get it installed at the original new car dealership from a professional. It doesn’t work at all and it’s very complicated to install. I’ve asked for money back, but I haven’t heard anything yet. Avoid avoid avoid.

## Questions & Answers

**Q: Does it work with metal bumpers?**
A: No,it can't. The detection radars are installed on the inside of the rear bumper of the car and cannot penetrate the metal. (The detector signal emitting surface cannot be blocked by metal).

**Q: Is any drilling required ?**
A: No need to drill holes. The detectors take the inside of the rear bumper sticky mounting design, and you need to confirm the angle when installing it.

*by D***S on 3 November 2025*

Works well, however in 2018 malibu brake and blinker share the same wire, resulting in beeps when passed at stop light. Going to use a nc relay controlled by the brake to disable the buzzer when the brake is pushed.
