Wireless Doorbell Kit: 1 Button and 1 Plug-In Chime, US Plug

Add a doorbell without running cables: stick or screw the black push button by the door and plug the square receiver into any outlet inside the house, shop or office. This set contains one button (3.4 × 7.4 × 1.8 cm) and one receiver (8.2 × 8.2 × 3.1 cm) with a US-type plug, the type used in Colombia. The button runs on a dry-cell battery; the supplier does not state which type. It is a sound chime only, without camera or intercom audio. Package: 1 transmitter + 1 receiver.
