A wireless doorbell eliminates the need for internal wiring, can be installed with minimal tools, and the chime box receiver can be placed anywhere within the range of the doorbell transmitter. A wireless doorbell system generally consists of two components: a doorbell transmitter and a chime box receiver. When a visitor pressed the wireless doorbell button at the front door, the battery-powered transmitter sends out a signal over a designated radio frequency. The receiver inside the chime box detects this signal and emits a loud electronic tone of the owners choosing. If there are several receivers within range of the transmitter, all of them should chime simultaneously.
