    • An intrusion detection system for generating alarm signals on detection of intrusion events is able to discriminate between intrusion events and nuisance events such as wind, rain, vehicular traffic and other environmentally related non-intrusion events. A signal monitor monitors a time variable detected signal for a occurrence of a signal characteristic indicative of a detected event. A signal processor is operative on a detected event to evaluate whether over a time interval the detected signal satisfies a combination of separate criteria indicating an intrusion event or a different combination of separate criteria indicative of a nuisance event and to generate an alarm signal only if the evaluation is indicative of an intrusion event. In one system, the signal characteristic indicative of a detected event occurs when the detected signal exceeds a level crossing threshold and the signal processor is configured to extract from the detected signal a measure of continuity of signal over the time interval, a maximum signal amplitude strength measure and a maximum amplitude deviation measure and to perform a decision tree process in which successive decisions are made as to whether a combination of criteria identifying an intrusion event has occurred.
