A kinetic doorbell is a wireless doorbell that doesn't require a battery in the doorbell button. Instead, it generates a small amount of electricity from the physical press of the button.
Here's how it works:
• Pressing the button moves a tiny mechanical generator inside the doorbell.
• That movement creates enough electrical energy (kinetic energy converted to electrical energy) to send a wireless radio signal.
• The indoor chime unit, which is plugged into a power outlet, receives the signal and plays the selected ringtone.
