Mobile technology specialist TenBu today launched a Bluetooth based security gadget called Nio that protects laptops and other Bluetooth devices while you’re away from the office. Nio works by creating Bluetooth links to your mobile devices and sounding an alarm if the link is broken, such as would happen if you accidentally abandoned one of your devices in a restaurant or if a thief tried to run off with one.

This is an interesting use of Bluetooth technology, but it raises several questions. For example, Bluetooth devices have a poor reputation for battery life. Although the makers claim Nio’s battery would last for several weeks before needing a recharge, it remains to be seen what impact using Nio would have on the batteries in laptops and mobile phone.

Similarly, the Police and insurance companies may not welcome such devices without reservation. After all, thieves are unlikely to return stolen goods just because the victim starts shouting at them.

Here’s a very laid back video promo from the makers of Nio.
