The use of a wireless doorbell entails the transmission of the chime signal from a receiving unit to a button or transmitter, powered only by a mere battery. The receiver would actually chime or ring due to the radio frequency signal that it gets from the button. Installation is easy and flexible since these systems do not involve complex wiring. The features that most of these wireless doorbells often have include volume control, changing of tones, and in some instances, there are those that have visual alerts that can increase the convenience and security at home.
