Abstract
A system for monitoring the occurrence of an event occurring with respect to an essentially metallic enclosure such as a truck body, e.g., the unwarranted opening of a locked door to the enclosure, which comprises a detector within the enclosure which senses the occurrence of the event and radiates a spread spectrum signal which is readily received by an external module mobile relative to the enclosure, so that the enclosure, at any time during its active life, may be externally interrogated to ascertain whether any such event has occurred, the enclosure optionally also containing a separate unit which records the spread spectrum signals for subsequent display and analysis, whereby the security status of the enclosure may be externally monitored at will, thereby to indicate whether or not the enclosure has been tampered with and, optionally, its security history--when and how frequently the event has occurred--may be retrieved.
