Review on Optimized 433MHz Home Wireless PIR Infrared Motion Detector Sensor for Alarm System by KERUI by Chad Delgado
Unstable, unreliable. Find the best alarm clock.
They drain the battery fast and get unstable (false alarms) when the battery gets low so I reconnected the transformer to 9V which was a big improvement but still loud and nasty false alarms gave. I replaced the first motion detector with this one and that seemed to fix the problem for a while but after 4 or 5 months the same thing happens again. I gave them up and it's a shame. That would be a good answer to the double robbery of my workshop.
- Easy install
- Hard to tell
