One of the issues with wireless technology is that at some point it will require a battery replacement or charge, but the KooPower Wireless Doorbell Kit looks to make this a requirement of the past.
The doorbell kit features a main hub within your home for playing the sound along with the exterior button that guests can press to let you know they have arrived. The button features a piezoelectric generator within that will create a small electrical charge when pressed that is just enough to send the signal to the main hub, which completely eliminates the need for wiring or batteries altogether.
The KooPower Wireless Doorbell Kit boasts a 500-foot range and can be customized with your choice of 25 different ringtones.
