Cabinet with tamper detection system and method

A tamper-detection system for attachment to a panel, comprising:

• a substrate;
• at least one conductive trace attached to said substrate, for attachment to a protected region of said panel, wherein the minimum distance from any point in said protected region to said at least one conductive trace does not exceed 50 mm;
• an electrical current source to provide a current through said at least one conductive trace;
• a sensor in electrical communication with said electrical current source to sense a change in current provided to said at least one conductive trace and generate a tamper signal in response thereto.

A method of detecting tampering with a cabinet, comprising:

• providing a cabinet enclosure having a plurality of panels;
• providing a tamper-detection circuit comprising a current source, a conductive trace on a protected region of at least one of said panels, and a current detector;
• detecting a change in current provided to said conductive trace;
• generating a tamper-condition signal.

A cabinet comprising:

• a plurality of panels;
• an electrical circuit comprising:
• at least one conductive trace on a protected region of at least one of said panels, said at least one conductive trace arranged in a pattern, said pattern having a pitch less than 50 mm and spanning substantially the entire surface of said one of said panels;
• an electrical current source to provide a current through said at least one conductive trace;
• a sensor in electrical communication with said electrical current source to sense a change in current provided to said at least one conductive trace and generate a tamper signal in response thereto.
