A facility may include antennas directed to a known location and cameras with a field-of-view that encompasses the known location. The antennas acquire a device identifier and device data from a mobile device carried by a user at the known location. Antenna data is then generated to describe the data acquired by the antennas. Image data is also generated from the cameras to include images of a person at the known location. The antenna data and image data are then processed to determine estimated motion values and a comparison of such values is performed to check if such motion values are within a threshold of one another. If the motion values are within a threshold of each other, data indicative of presence of the mobile device at the known location is generated.

A facility monitoring system and/or a secure data storage device transport trolley accounts for data storage devices removed from rack computing devices while in transport. The secure data storage device transport trolley comprises a backplane, backplane connectors, and a computing device coupled to the backplane. The computing device scans for data storage devices connected to the connectors of the backplane at regular intervals and maintains an updated list of data storage devices being transported by the secure data storage device transport trolley. The secure data storage device transport trolley also provides the list to a facility monitoring system for reconciliation.

A tamper detection system utilizes a barrier that includes a bar sized to extend across a rack in an arrangement in which the bar blocks access to an appliance received in the rack. The tamper detection system further utilizes a detector configured to log, transmit, or otherwise generate an indication that the barrier has been tampered with, such as in response to the bar being pulled away from the rack enough to decouple a magnet that when magnetically coupled to the rack maintains a switch in a first state against a biasing force of a biasing mechanism urging the switch toward a second state, or such as in response to the bar becoming severed or pulled away from the rack enough to cause a detectable change of resistance or other electrical characteristic in a corresponding circuit.

This disclosure describes RFID tags that include capacitive shields to capacitively couple with antennas of the RFID tags when exposed to threshold levels of electromagnetic energy, such as when placed in a microwave. In some instances, these capacitive shields comprise a material that is both thermally conductive and electrically conductive. When exposed to electromagnetic energy of a high frequency, the capacitive shield may capacitively couple to the antenna of the RFID and, thus, may receive energy from the antenna. Given the properties of the capacitive shield, the capacitive shield may convert this energy into thermal energy and dissipate this heat into an ambient environment of the RFID tag. By doing so, the capacitive shield lessens the risk that dangerous arcing will occur from the electromagnetic energy.

An entry portal to a facility may include radio receivers with directional antennas and cameras at known positions in the facility. The receivers acquire device identifier and device data from a mobile device carried by a user passing through the portal. Portal data is generated that is indicative of the coverage volume of a particular antenna that received a signal carrying the device identifier and signal strength of that signal. The cameras acquire images of the user. Other sensors may acquire other information included in the portal data. The portal data, device data, device identifier, and the images are processed to associate a particular account with a person passing through the entry portal. Subsequently, that person may then be tracked using images from other cameras in the facility.

A tamper detection system utilizes a barrier that includes a mesh sized to extend across a rack in an arrangement in which the mesh blocks access to an appliance received in the rack. The tamper detection system further utilizes a detector configured to log, transmit, or otherwise generate an indication that the barrier has been tampered with, such as in response to the mesh becoming severed or pulled away from the rack enough to cause a detectable change of resistance or other electrical characteristic in a corresponding circuit.
