I have a confession to make: I'm usually not a big fan of anything I see as a "novelty" product. Sure, there are cool ideas, but I'm all about usefulness. Things that make life easier, more convenient, or just generally better. I think the DoorBot is one of those things.
The DoorBot, in short, is a W-Fi doorbell with one-way video and two-way chat. Here's how it works: someone rings your doorbell, which notifies you on your phone. You answer it like a call, thus activating the DoorBot's camera so you can see who's there. Then you're free to talk back and forth.
