*by O***R on 3 December 2025*

This motion sensor easily integrated into the other sensors I had already installed on my detatched garage. The price is excellent and it worked great under testing. I have had no false alarms under all weather conditions. The key is proper placement and make sure each of the other sensors have their contacts nice and close on each door/window. If the gap is too big, a small movement from wind or temp changes will trigger false alarms. The value for the Kerui alarm is excellent! A side note: This brand does a great job with their alarm speaker. It is super loud and perfect for a non-monitored system.
