An object of the invention is to provide a monitoring device that can be mounted in a window or a door in which because the window is often opened or closed by the user, if the monitoring device is installed on the window, the user must perform an operation of releasing the monitoring device, every time of opening or closing the window. An intrusion detecting terminal unit ( 13 ) having an opening/closing sensor is disposed on the window or door, a mat ( 16 ) containing a piezoelectric sensor ( 15 ) is disposed near under the window, and each of the intrusion detecting terminal unit ( 13 ) with the opening/closing sensor and the intrusion detecting terminal unit ( 15 a) with the piezoelectric sensor comprises data communication means for transmitting or receiving data. In case of the intrusion, the intrusion detecting terminal unit ( 15 a) under the window detects the intruder, and then if the intruder tries to open the window, the intruder is judged. However, when the user opens the window, the intrusion detecting terminal unit ( 15 a) does not make the detection, and the intrusion detecting terminal unit ( 13 ) alone detects the opening of the window, whereby the user does not need to release the monitoring device every time of opening the window.
