One of the more interesting real estate products featured at the January 2013 Consumer and Electronics Show is the Doorbot. The Doorbot is a wi-fi-enabled doorbell that will alert you when someone pushes the button (doorbell) sending a signal to your smartphone. The Doorbot features a relatively simple installation, and it can be combined with a related product called Lockitron. Lockitron will allow you to open the door remotely via your smartphone. Doorbot is a project of crowdfunding site Christie Street, and while not yet commercially available it certainly has potential.
