Ring Video Doorbell

Ring wired WI-Fi video doorbell | $15 off

This is Ecobee's newest smart thermostat, and it's just called SmartThermostat. The name is annoying, but the product is fantastic. It improves on all the previous generations and includes a whole new design with a glass finish, a vivid touch display, a quad-core processor, dual-band Wi-Fi, Bluetooth, and far-field voice recognition that can pick up your commands from across the room. Like the Ecobee 4, this one comes with its own smart sensor. And you can add more.

The Ring Video Doorbell can show you who's at the door in 1080p resolution. That means capturing every detail, including the face of the neighbor kid who just ding-dong-ditched you. The camera also comes with night vision, which helps you see more clearly when it gets dark. The advanced motion detection can send real-time alerts to your phone whenever someone comes by. Plus, the doorbell is smart enough to filter out movement like a car driving past or a busy street with pedestrians walking by. Only get alerted when it really matters.

You'll also have two-way audio so you can hear everything going on, and you can communicate with whomever is at the door from anywhere.

The video doorbell's compatibility with your smartphone means you can control it from anywhere. Get your live feed anywhere. Talk to people from anywhere. Did your sister stop by but you're at the grocery store? Let her know you'll be a few more minutes.

This is a wired doorbell so it uses your existing wiring to easily attach to your front door. While it might be a bit more complicated to install, that means you won't have to worry about recharging a battery or anything like that since it will draw power straight from that wiring.

Use the Ring app on your iOS or Android smartphone. Connect the video doorbell to Amazon Alexa for voice control. Use the Ring Chime (if you choose that bundle) to get audio notifications throughout your home.
