ABSTRACT:
A modular processor unit, known as an ASP unit (50), is provided for intelligently enhancing a conventional physical security system (20) without significant reconfiguration. The unit (50) is installable between conventional sensors (30) and a conventional transponder (28), the transponder being in communication with a central control station (22) of the system. The ASP unit (50) analyzes, over a period of time, a plurality of preselected features of the signal received from said sensor and used the features to evaluate a polynomial and thereby classify an event as an intrusion or a nuisance. The ASP unit (50) further includes an output state simulation relay switch (72) responsive to the classification for simulating an element of the sensor (30) and for providing an output state to the transponder (28). In one embodiment, the ASP unit (50) is connected by an ASP communications network (52) to a retraining workstation (54). Upon installation of the ASP unit (50) or modification of sensors, the retraining workstation (54) can be used to download both sensor-related and classifier-related parameters to the ASP unit.
