This is a great door alarm, especially for the money. We live in a very large 3 story home. Our doorbell can be heard from only the main floor and even then it’s weak. It was very easy to install and operate. This alarm can be heard from anywhere I. The house. It’s small and unobtrusive. I love that you can choose different sounds. I giver it a BIG two thumbs up! 👍🏻👍🏻
So far so good! I purchased these door alarms to help me with my 5 year old granddaughter.... sometimes she sneaks out the backdoor to go play with our dog NOT ANYMORE! Once she tries opening the door a loud siren goes off!! Now, she shuts the door and runs back to her room... I highly recommend this product!! Thank you!
It took a little while to become comfortable with the setup. Once we did it was very easy. It does take a little while to setup each pair. You can have 20 separate transmitters paired to 20 separate receivers and each combination can have it's own ring tone. That would leave my head spinning, but it's possible.
The two receivers + three transmitters are perfect for a store front with a back door for deliveries. One sensor on each of the double front doors, set to the same ring tone on each receiver. The back door can have it's own ring tone on each receiver.
I bought these so our office could tell if someone had come through the front door. Sometimes employees are in the back room or not available in the lobby. It just helps everyone hear that someone has entered. The fact that you can change the ring or sound and the volume is a great help to find something that is not too long or short, too repetitive, too weird, more Goldielocks, just right.
We use this in our family store. It works prefect and has such a great variety of ring tones so that you can choose one that fits your needs best. The only downside is that each time you unplug it, it needs to be reprogrammed. It is not a huge issue for us but we are renovating the store and each time we move it we have to reprogram it. Other than that, it works perfectly!
