Rating : - Does the job, and very well
This motion detector is simply Excellent, it works flawlessly.
I use it in my office, so when someone enters to the reception area, I immediately notice, with the nice receiver; it has two sound modes, one sounds like a door bell.
Very easy to install, just put the batteries, place the motion detectors, and adjust the way you like the unit to sound.
The distance between the sensors and the receiver, I placed them about 40 ft, and they work very well.
