Abstract: An exemplary detection apparatus includes a housing having one or more sensors of one or more sensor types, an optional port for detachably mounting one or more of the sensors, and an optional motive system associated with a mode of transport for movement in an area of interest. A sensor circuit receives a signal originating from the one or more sensors, identifies the signal, optionally processes the signal data, and packages the raw signal data or processed signal data, as applicable, for transmission over a network. A control circuit establishes communication with the network for sending or receiving sensor data to/from other devices connected to the network, and controls the motive system for moving the apparatus to locations in the area of interest.
