I needed a ceiling mounted sensor (my ceiling is 9') that would detect or my dogs from 20' away. The configuration settings offered the flexibility I needed.

I recently installed the CMR9 sensor as part of my home security system, and I'm blown away by its performance! Not only does it look sleek and modern, but it's also incredibly effective at detecting even the slightest movements. The sensor's compact design makes it easy to place discreetly in any room, and its wireless connectivity ensures seamless integration with my existing security setup. But what really impresses me is the CMR9's accuracy and reliability. It consistently picks up movement without false alarms, giving me peace of mind knowing my home is secure. Overall, I'm thoroughly satisfied with the CMR9 sensor. Its combination of sleek design, ease of use, and top-notch performance makes it an excellent addition to any home security system. Highly recommended!

I use these on projects all the time. These were bought here due to price. They are cheaper here than at local supply house and exact some unit.
