Homeowners may also prefer not to drill because doing so could damage or crack the stone. Installing wiring simply for one doorbell button can therefore be inconvenient. In such cases, a wireless push button is a suitable choice.<\/li>\n<li>Battery-free wireless doorbell push button: The push button generates the required energy when pressed and transmits the signal to the chime receiver. The chime receiver can be plugged directly into a 220V power outlet.<\/li>\n<li>Expandable pairing capability: In large houses with multiple floors and entrances, a single chime receiver may be difficult to hear throughout the entire property.
