US – A new smart door lock called Lockitron lets people control who enters their house remotely, tells them when visitors knock, and sends alerts when family members arrive home.
The device is controlled through an iPhone 4S or iPhone 5, and unlocks the door using Bluetooth when it senses you are near. The lock has its own WiFi network, so it operates even if your home internet is unavailable.
This is a well-executed example of The Internet of Things in its early stages. For more on how this will affect the home of the future, read our Future Family macrotrend.
