So admittedly this one is a little bit drier than the rest of the list, but still very cool and useful. You can buy doorbells which also feature a little camera that’s activated when someone rings the bell – this is obviously useful so that you can ensure there isn’t a murderer or pesky salesman at your door before you answer.
Smart doorbells go a step further though – when someone rings the doorbell the camera sends a video straight to your smartphone. You can both see and talk to whoever is at your door from not only inside your home, but from anywhere. You could be on the other side of the world, and still be able to talk to whoever is at your front door. You can buy a smart doorbell from Doorbird, Skybell, or Doorbot. They’re pretty reasonably priced.
