Abstract
Embodiments of the invention prevent unauthorized access to electronic systems by providing an enclosure with improved intrusion detection around sensitive areas of a secured electronic system. Certain embodiments eliminate the need for constant battery power and yet provide uninterrupted high-security supervision at the device perimeter such that even following a power down event it is possible to determine whether a device has been tampered with, so that appropriate action can be taken. This is especially useful in applications in which batteries are not acceptable.
