1. Wireless doorbell
A wireless doorbell is a modern alternative to traditional wired doorbells. It consists of a doorbell button (transmitter) and a receiver unit. When the doorbell button is pressed, it wirelessly sends a signal to the receiver unit, which is typically plugged into an electrical outlet inside the house. The receiver then emits a chime or sound to alert you that someone is at the door. Wireless doorbells are easy to install since they don't require complicated wiring.
