Abstract

The present invention provides a security system (10) that may be used for a wide range of security applications. The security system (10) includes a control unit (12) in electrical communication with one or more field-generating sensing elements (28). The security system (10) includes at least one oscillator (32) for generating a sensing field signal that is communicated to the field-generating sensing elements (28). The field-generating sensing elements (28) receive the sensing field signal to generate a capacitive sensing field whereby when an object approaches or intrudes the object-sensing field, the control unit (12) operates to activate an alarm mechanism (15).
