Want to keep an eye out for porch pirates? Or perhaps you're seeking a simpler way to see who is at your front door without having to get off the couch? Smart doorbells are still fairly new to the world of home security, and the market is becoming more and more saturated with options by the minute. This begs the question: How do you know which one is right for you and your home? I've been living with the Ring Video Doorbell Pro for about a year and a half now.

If you want to make a bit of a statement at your front door, the August Doorbell Cam Pro 2 will do the job. At just under three inches square and an inch deep (7cm square and 2.5cm deep) and with a large oversized button, it's sure to be noticed by callers. It provides a clear image and in my testing didn't get set off constantly by passing cars or leaves blowing around in the wind. There are a couple of tweaks I'd like to see and the subscription fee is on the high-end, but if you have an existing August smart lock (the August Smart Lock Pro us is our top pick in the retrofit category), the doorbell makes a good companion. One consequence of the square design is that you'll need to make sure the bell can fit where you intend.

Do you want to see who's at your door without getting up, keep an eye out for criminals and hooligans, or simply make sure the delivery guy actually leaves your package while you're at work? With a video camera that lets you see who's at your door, two-way audio, and alerts that stream right to your smartphone, even when you're not home, a smart doorbell might be the perfect device to add to your home. To find out which will really ring your bell, I tested seven of the most popular models. Truth be told, none of them were perfect--but the Ring Video Doorbell 2 (available at Amazon for $199.00) With the most reliable connection and the fastest response time, the Ring 2 is the best bet for any house, especially because it's one of the only models that can run on batteries or be hard-wired.
