The Doberman Bag Protector Alert is a uniquely designed dually triggered alarm device, including a motion sensor alarm and a pull pin alarm. The motion sensor is armed and disarmed via the Bag Protector Alert keypad. Use your preset personal security code and place the Bag Protector Alert on a bag or valueable. If the protected item is touched, the motion sensor will trigger the alarm to alert you of a possible threat to your valueable.
