Review on Optimized 433MHz Home Wireless PIR Infrared Motion Detector Sensor for Alarm System by KERUI by Steven Emberling
Great for the price
There is a problem with this product. If a power failure occurs and the buzzer turns off when power returns, it will not restart automatically. This leaves your property unprotected until you return home and physically arm it. This is the biggest problem with this system.
