Dropcam Pro

Best for Basic Room Viewing

The 4.5-inch-tall Pro takes just a minute to set up and monitors any room of the house, streaming 130-degree HD video to your phone. If you miss anything, you can review a day's worth of footage in fast motion, and the cam sends an alert when motion or sound is detected. It's a cool feature if you want extra security, but luckily it can be disabled so you don't get a text every time the dog barks. [$199; dropcam.com]
