Zero false alarms in 6 months of use
After experiencing a break-in where our old sensors failed to detect the intruder, I upgraded to these. The dual-technology detection (PIR + microwave) means virtually nothing gets through undetected. Our security company confirmed these are the best sensors they've seen.
Covers a huge area with one sensor
The installation was simple — mount, pair with the panel, done. The sensitivity adjustment is useful for fine-tuning coverage without false alarms. I've been using these for 14 months and they've performed flawlessly through extreme heat and cold.

Zero false alarms in 6 months of use
I have two large dogs and was worried about constant false alarms. This sensor has been perfect — in 6 months of daily use, it has never once triggered from my 80-pound Labrador. But it catches every human intruder attempt in our testing. Exactly what I needed.
