- 77 doorbells
With a doorbell, you're immediately informed when someone is at the door. There are wireless doorbells, WiFi doorbells, wireless intercoms, and smart doorbells. Before choosing one, determine whether you want a doorbell with a battery or a powered doorbell. In addition, you can choose a wired or wireless connection. By placing a physical receiver or chime in a central location, you can hear the ringing signal throughout your home. Some doorbells have multiple receivers. A smart doorbell with camera shows you who's at the door in the app. A doorbell with app also allows you to communicate with your visitors remotely.
