Ring Video Doorbell | $100 | Amazon

Amazon just officially closed on its acquisition of Ring, and the first order of business is dropping the price of the standard video doorbell to $100, which is one of the best prices we’ve ever seen on it.

Ring’s video doorbell lets you see who’s at the front door, even if you’re halfway across the world. Plus, it can be powered via its internal battery, or wired directly to your home, so you don’t have to choose.
