This wireless DoorBell has one button and two receivers which is really nice because we have 2 houses on the property here so we can be in either house and still hear the doorbell.
I received this bell earlier, but it only had one receiver. I thought this would be fine because I am usually in my own house. However, I found that occasionally I would miss a customer because I would be in the main house when they would stop by and I wouldn't hear the bell in the house. Now that I have this one with two receivers, I can put one in each house and I won't miss another customer because of not hearing the bell.
You can get this item Here on Amazon.
Have a great day!
