Illustration for article titled BlueGuard Opens Doors When You Get Within Bluetooth Range

Oh the convenience of not having to use keys—that's what you get with a Bluetooth-enabled cellphone and BlueGuard, the automatic door opener.


The $200 unit detects up to 10 separate cellphones at up to 33 feet (standard low-power Bluetooth range), and hooks up to the door-opening system to enable you to get hands-free entrance. The site says this is more of an industrial use, and attaches to "gates, overhead doors and parking barriers," so it's less of you getting into your home. Still, it's quite useful.
