In recent decades, wireless doorbell systems that do not require wall wiring have become popular. The doorbell button contains a built-in radio transmitter powered by a battery. When the button is pushed, the transmitter sends a radio signal to the receiver unit, which is plugged into a wall outlet inside the building.
The wireless receiver is the component that physically connects to your computer and picks up the wireless signals from your keyboard and mouse, allowing it to communicate with your system. Note: Some setups will have two wireless receivers - one for the keyboard and the other for the mouse but the setup instructions will otherwise be the same.
