The DEFCON™ 3 Security System is the most advanced protection available to mobile computer users combining the convenience of a remote control with a 94 decibel alarm. To operate you simply attach the unit to your computer carrying case via the stainless steel cable. The DEFCON™ 3’s remote control keychain span is up to 12 metres away making this the perfect travel companion for airports, hotel lobbies, car rental counters and more. The technology in the DEFCON™ 3 detects when the cable is severed or the item is moved or shaken, triggering the piercing alarm. LED lights provide a visual deterrent and an ‘armed’ alarm status. Plus, your remote control ID code is unique and will only respond to your unit, not others. You can activate, program, arm, disarm, and deactivate at the touch of a button.
