Review: dependable, loud configurable.. works great. - works great. i use 2 separate devices this is one.. motion detection on a door.. along with a magnetic switch sensor. can't have old old old people wandering off in the middle of the night and freezing to death or getting lost.
Review: Works Perfectly, Great Value - I bought this unit for use as a motion activated doorbell for my store as the one we had was way too quiet to be effective. The unit was easy to install and works perfectly; it's a great value at under $30. The chime unit can be free standing or mounted. The motion sensor can be mounted with mounting tape or screws (included) upside down sideways and has an adjustable bracket. I recommend using screws instead of the mounting tape included as the mounting tape is the standard two sided white foam type that will eventually dry up after a few years and sensor may fall. If you don't want to use screws, I would recommend you buy some 3M auto molding tape which seems to last forever and is very hard to remove. The sensor and transmitter range is fantastic and I had no trouble in my store with it (supposedly it has the range of up to just over the length of 3 football fields). I initially just put batteries in the chime and motion sensor after unboxing and installed them. The default setting is a motion activated door chime that is a loud ding dong ding dong. I did not realize that the unit had a host of other tones, features, voice you can program using the 4 buttons on the unit. I found the programming to be a bit tricky and for my use, the other features are overkill since I just needed it as a motion activated door chime. After messing with it, I found out that it has 4 volume settings. The default setting is set at the LOUDEST setting which is great for some uses. For my roughly 10,000 SQ FT store, the second volume setting is adequate if you do not have any background music playing.

## Features
