The BlueWatchDog is a new Bluetooth device that we can describe as a first of its kind. Why, this is a virtual perimeter device which functions as an anti-theft alarm. Not entirely a new concept but the Bluetooth technology is just more efficient to use.
Attach this device to your bag or gadgets and you’ll know if someone stole it or if it is outside your specific radius. Just remember you set the alarm or else you’ll be too surprised with the shrieking sound it produces.

Price tag reads $69.
