Doorbot allows homeowners to see who is at their door from the security of their iPhone. Equipped with a camera, the Doorbot is simply screwed into the door frame of a house, and with the push of a button contacts the homeowner’s phone with a video. The homeowner at that point can let the person in with the press of a button. The company is looking to raise $250,000 in order to turn Doorbot from a concept to a readily available product ranging from $169-$319. [Source: Engadget]
