Review on Optimized 433MHz Home Wireless PIR Infrared Motion Detector Sensor for Alarm System by KERUI by Leslie Matlak
Unstable, unreliable. Find the best alarm clock.
They drain the battery quickly and become unstable (false alarms) when the battery gets low so I replaced the wiring with a 9V transformer which was a big improvement but still caused loud and nasty false alarms. 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.
- Everything is fine!
- Expensive
