Review on Optimized 433MHz Home Wireless PIR Infrared Motion Detector Sensor for Alarm System by KERUI by Matt Welch
Works well indoors but NOT weatherproof
The price is right but they have to make an outdoor version of the motion sensor. The device is NOT weatherproof. When used in a dry environment, the detector works well in "doorbell" mode and also works well in "alarm" mode. The on/off switch is useful if you want to disable a specific motion detector but leave the rest of the system on.
- Very good value for money
- There are other interesting options.
