What is a Doorbell?
A doorbell is a signaling device that is typically placed near an entry door to a building. When a visitor presses a button the bell rings inside the building, alerting the occupant to the presence of the visitor.
What is a Wired vs. a Wireless Doorbell?
A wired doorbell features a circuit that is completed when you press the button. When the circuit is complete, the chime or buzz sound is activated.
A wireless doorbell features a battery operated transmitter that sends a radio signal to the receiver unit to activate the sound chip when the button is pressed.
One Pushbutton vs. Two Pushbuttons?
Doorbells with one pushbutton are ideal for residential locations while doorbells with two pushbuttons are ideal for commercial locations with more than one entrance.
