Ring Battery Doorbell Plus ($120, originally $180)

The Ring doorbell is a genius way to stay safe when you're home or on vacation. When someone arrives at your doorstep, you get a notification on your smart device and a live video feed showing who's there. Perhaps the coolest part of all is the two-way communication feature that allows homeowners to speak to the person at the door through a built-in speaker and vice versa.
