In some implementations, a wireless sensing system may receive sensor data associated with an asset. The sensor data may be associated with a tampering event and the tampering event may include an action performed on the asset. The wireless sensing system may further determine whether the tampering event is performed by an authorized user of the wireless sensing system. The wireless sensing system may further determine whether the tampering event is performed within an authorized location of the wireless sensing system. The wireless sensing system may transmit a notification to a user of the wireless sensing system. The notification may alert the user of the wireless sensing system that the tampering event has occurred.

Disclosed are apparatuses and corresponding and associated methodologies for achieving current inventory data management in combination with an electronic access control system. An access control system provides access control data while the sealed enclosure incorporates an RFID reading system for determining the identity of respective tagged contents within the enclosure. Particularly in conjunction with the storage of controlled substances, such as some drugs utilized on an EMS vehicle, a form of RFID tag may be practiced which operationally is fully or partially destroyed or damaged, or otherwise impacted or affected so as to generate a changed ID, whenever the contained medicinal dosage is acquired for administration. By reading contents of the enclosure (narc box) prior to a work shift, and at the conclusion of the work shift, comprising tracking comparative methodology, usage of the tagged drugs may be tracked. By forming such reports throughout the course of a shift, as each point of consumption takes place, a complete record of custody of control may be maintained.
