Abstract
A system includes a device including one or more sensors that generate one or more signals used to detect whether an unauthorized activity has occurred at the device. The device is configured to transmit the one or more signals generated by the one or more sensors. The central monitoring device is configured to receive the one or more signals and compare the one or more signals with a baseline signal for the device. The baseline signal includes an expected signal for each of the one or more sensors when the unauthorized activity has not occurred. The monitoring device determines whether the unauthorized activity has occurred based on a result of the comparison.
