A security device () is a compact and inexpensive device for monitoring the integrity of closed objects that indicates when the state of a monitored condition inside the closed object has changed. The device () is small-sized so that it can also be placed inside small closed objects, e.g. a briefcase, box, envelope or alike, and that it is inconspicuous to the observer if the closed object is opened. The device () is relocatable inside the closed object. The device () comprises a controller () and associated memory (), a time counter () in connection with the controller (), sensors () communicating with the controller () and arranged to sense changes in conditions inside the closed object and indicating means () communicating with the controller () and arranged to wirelessly indicate invasion against the integrity of the closed object. While the changes in conditions inside the closed object comply with certain predefined conditions the alarm indication can be blocked. The alarm indication of the security device () can also be activated and deactivated externally by means of a remote control or automatically.
