  • Works Perfectly, Great Value
Color: 1 Receiver & 1 Transmitters
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. ... show more

  • Works perfectly for my needs, needs a better manual.
Color: 1 Receiver & 2 Transmitters
My cat is not "allowed" to go upstairs but she sneaks in anyway. I needed something that would detect her going up the stairs immediately. This works perfectly well for that. It doesn't really need to be installed, just placed vertically on a step (vertically so it only detects movement on the stairs). It doesn't get false alarms. The only thing I don't like is that the manual is pretty bad. It comes with an annoying voice and I wanted to change it to a chime. It takes a weird combination of button presses to get there and now I am stuck with the chime and lights on the detector that I didn't want. ... show more

  • Works great actually. Only wish there was a way to tell if it was armed without setting it off.
Color: 1 Receiver & 2 Transmitters
Really cool product for our needs. It has a good range, is easy to set up, and can use batteries or usb plug. Only complaint is that it needs to have some tone or way of alerting you that it is paired to the sensor and armed. It beeps for on/off, but you won’t know if the remote sensor is on and connected until you trip the alarm. Not a huge deal though, because as long as they are both on, we haven’t had an issue where they didn’t pair. ... show more

  • Works great
Color: 1 Receiver & 1 Transmitters
Used for a small in home office where my back is to the door. I don't like to be startled so this works great. For our purpose it's a little loud and I wish we can have only a beep without the voice, but that's fine. We just laugh about it. (But it can be a bit irritating) It's easy to turn on/off if needed. I'm sure it would be great for a small shop and customers would be welcomed with a friendly greeting. ... show more

  • VERY SENSITIVE! COMPACT SIZE! WORKS PERFECTLY!
Color: 1 Receiver & 1 Transmitters
I had previously purchased and sent back the 1byOne driveway alarm. This alarm system is engineered smart and works as it should right out of the box. Has all the options for alarm, welcome sounds,lights and other functions. What I like best about this unit is it's 2-way power, compact size and variable volume from soft to LOUD! I am using this as a doorbell. Don't hesitate! Buy it! ... show more

  • Easy to install
Color: 1 Receiver & 1 Transmitters
I got this unit because my mother has dementia/ Alzheimer’s. It’s the best thing ever. She has tried leaving the house in the middle of the night. This unit prevented her from leave the house. It’s went off right away. Thank you for this product.
