If you think a new front door lock isn't the most thoughtful holiday gift, you obviously haven't seen the $220 Kwikset Kevo Bluetooth deadbolt.
"You can carry your smartphone and as you approach the deadbolt, it knows who you are, and via touch, allows you to activate the deadbolt," said Keith Brandon of Kwikset.
Right now, the Kevo works with the iPhone 4S and all newer models. Android and Blackberry support is in the works.
The lock will also work with a standard key in case your phone battery is dead. In the event your phone is stolen, you can go online and instantly de-link your phone from your lock so it won't work anymore. Additionally, if you have youngsters in the house who don't have a phone yet, there are also Bluetooth key fobs you can hand out to unlock the door.
Another item, the $200 Doorbot, is not quite a lock but rather a Wi-Fi-enabled doorbell, so no matter where you are in the world, you can see and have a conversation with, anyone at your door.
"You can see them and reject the call if it's an unwanted visitor, or accept and say hello and talk to them," said Jamie Siminoff of Doorbot. "And it's voice, so it's cool. You can talk to them and see them."
For around $250, the Goji Smart Lock is a bit of a combination of the previous two. The door unlocks as you approach it with your phone. It can also help serve as video surveillance.
"As someone's approaching, we take the picture before the person actually arrives, so we make sure that way that we actually get the face of that person," said Gabriel Bestard of Goji Smart Lock. "And then, when that person interacts with the lock, we do have sensors on the lock that know if you're knocking or even if you're banging on the door and trying to break in. Then, we send you the picture along with a message of what's going on around your door."
Just like with the Kevo, Goji allows your door to be opened with a standard key, lets you deactivate your phone if case it's stolen and also works with Bluetooth key fobs. The Goji Smart Lock is compatible with both iPhones and Androids.
