The Ring Doorbell 2 is a $200 smart doorbell with a camera that lets you check in on your front door whenever you want.

I've been testing it for the past two weeks and, while there are a few things I don't like about it, it's great for anybody who wants to keep a watch over their front door without having to walk to it all the time -- people who work from home or get a lot of deliveries, for instance.

Let me tell you why.

This is the third Ring Doorbell

The Ring Doorbell 2 the third doorbell developed by Ring. This one offers 1080p video streams that are much sharper than the previous model, and costs only $20 more As with earlier models, it's water-resistant so you don't need to worry about it getting rained or snowed on.

It also has a rechargeable battery so you don't have to worry about hard-wiring it to your house, and support for detecting when people are outside of your house.

There's a button on the front that acts as your doorbell. When it's pressed, you'll receive a notification on any smartphone with the Ring application installed, allowing you to pull up a video feed of who's at your door.

It's not a particularly attractive product. It's clunky-looking, and was a bit of an eyesore on the front of my house. Admittedly, I have an older 1920s house that doesn't exactly match the look of modern technology.

Installation is a breeze

It took me about five minutes to get up and running with the Ring Doorbell 2. I installed the Ring app and connected the camera to my Wi-Fi network. The battery slides right into the bottom and the front shell — a white and a brown one are included in the box — snaps right to the front. It took just two screws to secure it to the outside of my house.

Speaking of the battery, it lasts long enough that I haven't had to charge it yet, and I've had it for about two weeks now. I suspect you'll need to take it off the door (it pops right out) and charge it every couple of months or so.

Always watching

The Ring Doorbell 2 will satisfy your curiosity (or calm your paranoia) about who's coming around. It allows you to check in on your front door — or anywhere, really — on demand from the Ring smartphone application. When I ordered pizza, for example, I was able to check in on the front door and see that it was the delivery person instead of, say, somebody trying to sell me something.

Sometimes the video had artifacts -- those glitchy bits that distort video from time to time -- but I could always easily make out who was standing outside. In one test with a colleague during filming, we found that the microphone wasn't always clear, so speaking anything other than a brief "come in" or "be right there" was kind of fruitless.
