Amazon video doorbells are on sale from $35 — 7 Ring and Blink deals with up to 69% off

Two years of battery life on three AA batteries is a genuinely impressive feat for a video doorbell, and that's before you factor in the HD video, night vision, and two-way audio through the app. Wired or wireless, setup takes minutes, and it works straight out of the box with Alexa.

Want to get a cheap headstart into a smart home security system? This deal gets you a Blink Video Doorbell and a Blink Outdoor 4 security camera for just $43. Sure, you can get sharper video and fancier features if you spend more, but if you just want an easy way to keep an eye on goings-on, this is a solid option.

The Ring Video Doorbell now comes in a slimmer shell, and new colorways — this one has a speckled gray finish. You also get upgraded Retinal 2K video, 6x zoom and two-way talk.

This is an affordable way to monitor both your porch and the inside of your home. You get a Ring Video Doorbell Retinal 2K video, 6x zoom and two-way talk — and a Ring Indoor Cam Plus with 2K video and super-easy setup.

The Battery Doorbell Plus has one major advantage over the basic model: Its battery is removable, so you don't have to take the entire doorbell off in order to recharge it. You're also getting 2K resolution, head-to-toe video and person and package detection — now for 33% off.
