Never miss an important visitor again! You can install a doorbell anywhere in your house with the Plug-In Wireless Chime. Mount the battery-powered doorbell at your front door, and when a visitor presses it, it transmits wirelessly up to 100 feet to the receiver, which can be plugged into any 120-volt outlet. Ideal for use in your workshop, laundry room, garage or patio, the Plug-In Wireless Chime allows you to hear the doorbell chime ring out in any room in your home.Additional Wireless Chime Options Available If you need to hear the doorbell in a location that doesn't have a convenient outlet, a Battery-Operated Wireless Chime is also available. If your guests arrive at both your front and back door, you can set up the 2-Entry Plug-In Wireless Chime. This system comes with two transmitters and a single plug-in chime that rings different tones to indicate where your guest is. An Additional Wireless Chime Transmitter is also available: Pick up as many as you need for doorbells at each entrance to your home.
