A device management system includes a first server and a second server. The access points implement multiple WLAN protocols, including a realtime protocol for realtime patient monitoring and a standard WLAN protocol for providing general-purpose wireless access. A pair of floating gate and control gate may be provided in one of the two enhancement type MOS transistors. A computing device is used to analyze the analytic alarm and the data from the at least one sensor to determine whether tampering of the security system component has occurred.
