The battery-powered version of the Google Nest Doorbell means you won't have to fiddle with wiring it into your home's existing doorbell system. And you're free to install it anywhere. The battery lasts about a month if your front door is a busy place, according to Google. If it's only recording two to five events per day, expect to get more like six months out of the battery life.

In addition to the convenience of not having wires, the Google Nest Doorbell comes in four colorway options, so you'll be able to find the one that best matches your home's exterior.

With the free Google Home app, you'll be able to keep an eye on your front porch through your smart device. Google integrated smarter detection into the video doorbell which can differentiate between a person, animal, and car, reducing the likelihood you'll get alerted about leaves blowing by.
