Ring Video Doorbell, $100

Update: Back in stock!

Ring’s video doorbell lets you see who’s at the front door, even if you’re halfway across the world, and you can outfit your porch with one for an all-time low $100. That’s down from its usual $180, and a match for early Black Friday ads that we’ve seen. Every Ring doorbell can be powered via its internal battery, or wired directly to your home, so you don’t have to choose.
