Review on Optimized 433MHz Home Wireless PIR Infrared Motion Detector Sensor for Alarm System by KERUI by Dragan Nelson

I installed this alarm under my Suburban to protect the fuel and exhaust systems. With catalytic converter and fuel prices increasing, I decided to set up and install this alarm on the underbody of my SUV to protect it from catalytic converters and fuel thieves. After setting up the system at my home, I cut the horn wires to connect directly to my car's batteries, attached magnets to the motion sensors, and placed them in small zippered bags placed near the exhaust pipe and fuel tank inlet became. Then remove the magnet in the door sensor and attach it to the fuel filler flap, which interacts with the door sensor attached with velcro. Due to the size of the SUV, I bought an extra horn and motion sensor; So I have now installed two horns, three motion detectors and a door sensor. I am very happy with this purchase.
