The ERA-EXKIT allows you to extend the listening range of a wired doorbell. Hear your doorbell downstairs, in a back office, or a garage or warehouse. Wire a small wireless transmitter to your existing doorbell and pair the transmitter to the plugin receiver included in the kit.
When a visitor presses the wired doorbell button outside, your wired doorbell will chime as normal, and at the same time, the plugin wireless receiver(s) will also chime. Add additional receivers throughout your home or office - basement, office, warehouse - and never miss a visitor or delivery again. At a range of up to 4,000 ft., this system will work in any size home or business!
