One device does it all. It’s like having a handyman around the house 24/7. It does it all. That would be our Wireless Premium Portable Door Chime all-in-one push button, chime extender and accessory converter. You can set it up to be your push button, extend the wireless range of your chime or convert devices to coordinate security with motion detectors and door/window alerts. If you have other devices already, this device brings out the best in them.
