Abstract

See full text

Various implementations described herein are related to a device having sensing circuitry that receives an input signal and provides an output signal based on sensing a resistance differential between multiple shield resistors or based on sensing a change in voltage across a shield wire of a shield wiring network. The device includes comparing circuitry that receives the output signal and provides an alarm signal based on detecting a tampering event associated with the resistance differential or the change in voltage.
