Electronic surveillance article systems reducing the number and likelihood of false alarms are provided. Such systems include two read zones, with a second read zone having an associated RFID reader configured to detect an RFID device at a trigger threshold. The trigger threshold may be set or modified in view of a value of a sensor of an RFID device (sensing a capacitance or dielectric permittivity or temperature or degree of movement, for example), the number of times the RFID device is detected in the first read zone, or whether the RFID device is detected in the first read zone under predetermined conditions. Such systems may also or alternatively initiate a response (e.g., modifying the trigger threshold or the amount of power transmitted by an RFID reader) when an RFID guard device associated with a piece of infrastructure in the first read zone is detected in the second read zone.

An electronic monitoring item system is provided that reduces the number and likelihood of false alarms. Such a system includes two read zones, with the second read zone having an associated RFID (radio frequency identification) reader configured to detect an RFID device at a trigger threshold. The trigger threshold can be set or modified in view of a value of a sensor (sensing, for example, capacitance or dielectric constant or temperature or degree of movement) of the RFID device, a number of times the RFID device is detected in the first read zone, or whether the RFID device is detected in the first read zone under a predetermined condition. Such a system can also or alternatively initiate a response (e.g., modify the trigger threshold or amount of power transmitted by the RFID reader) when an RFID protection device associated with infrastructure in the first read zone is detected in the second read zone.

A robot has an electronic surveillance system embedded within a chassis disposed between two wheels. The wheels include a main body and a plurality of treads. The treads are generally disposed radially around the main body and extend distally from outer portion of the main body. The main body generally defines a plurality of compression cells and may present a substantially frustoconical outer surface.

A system and method for monitoring, via collection systems mounted on vehicles, for one or more electronic signals associated with one or more selected locations. In an embodiment, the system may include a plurality of collection systems. Each collection system of the plurality of collection systems may be positioned on a respective vehicle of a plurality of vehicles. Each of the collection systems may include at least one sensor configured to collect electronic signals from proximal electronic devices and a communication circuitry to transmit collected electronic signals. The system may include an intelligence device receiving the transmitted collected electronic signals. The intelligence device may include a database and correlation circuitry to determine a correlation between one or more different electronic signals of the collected electronic signals.
