ABSTRACT:
Systems and devices are provided for detecting access to an object. A pattern of conductors extending in spaced, isolated configuration is provided on the object defining a tamper detection area. At least one sensor device is connected to the pattern of conductors and is capable of detecting a change in the continuity of the pattern of conductors. A communication circuit provides at least one signal indicative of the change in continuity of the pattern of conductors. The tamper detection area of conductors confronts each surface of the object.
