Replaced a 20-year old motion sensor with this little guy. For the price, i didn't expect too much, but it works flawlessly. I notice it picks up movement more often the the old unit and I no longer get false alarms. Very pleased.
My husband installed this sensor in the upstairs hallway which also faces the staircase. We needed to replace the old original sensor, that was in place when we purchased the house 26 years ago, which had stopped working. This sensor works perfectly! When adjusted, it can sense movement at the bottom of the stairs, coming up!
Replaced a worn out one in our warehouse. Worked great. No pets there, so we set it to full sensitivity.
Great item at a great price. The instructions need to be updated and on paper insert, not just printed on back of the back. Hard to read.
It does the job well.
