The BlueWatchDog Personal Anti-Theft Alarm is another of those virtual perimeter devices which sounds an alarm if your chosen item is moved too far away from your body. What makes this Swiss product different, however, is the fact that it alerts you via your mobile phone.
Someone swipes your laptop, the alarm triggers outside the chosen radius and your phone will start jangling at you. Simultaneously the alarm unit itself will emit a piercing sound, which will make the thief panic and drop the item [video]. Bad luck on that laptop hard disk eh? Anyhoo, all you need is a phone with a Bluetooth chipset embedded. £43.47 ex VAT.
BlueWatchDog is the only alarm system in the world that provides effective protection for your valuables using your mobile phone’s BlueTooth technology.
