So what is Lockitron? Just take a look at the following video:
I really like the idea and concept of Lockitron. Not only can it be installed at the main door, Lockitron can also be installed at the door of your own room. This is particularly useful if you want to secure your (secret?) room from small children or strangers. It is also useful if you are renting our your rooms and you want to secure your own room. The only issue is that Internet connection must always be on.
Lockitron was featured in CNN. You can check it out at this link.
