PURPOSE: A security device for glass door and a fabricating method thereof are provided to prevent the invasion by installing a vibration sensor between two glasses of a double glass door. CONSTITUTION: A security device for glass door includes a double glass door(10), a vibration sensor(30), and a main controller(50). The double glass door(10) is formed with the first glass plate(11) of an outdoor side and the second glass plate of an indoor side. The vibration sensor(30) is adhered on an inner face of the first glass plate(11) in order to sense the vibration of the double glass door(10). The main controller(50) is used for receiving a wireless invasion signal received from the vibration sensor(30), generating an alarm signal, and controlling an operation of the vibration sensor(30). The vibration sensor(30) is formed with a piezoelectric vibration sensor(31) for converting the vibration to a current signal, a controller(33) for deciding an invasion state by referring to the current signal, a transmitter(35) for transmitting an invader sensing signal, and a power supply(39).
