Methods, devices, and systems that aggregate and retrieve network sensor data. In one approach, an exemplary method includes receiving a plurality of instances of correlated sensor data from a plurality of remote data storages, each instance of sensor data respectively correlating to an occurrence. In another approach, an exemplary method includes receiving from an input-selector an input selection corresponding to a target-occurrence having at least one representative feature, and searching stored sensor data for sensor data correlating to the target-occurrence.
