Abstract

A wireless integrated network sensor (WINS) system is provided that integrates articulating tracking systems with WINS network components including visual or infrared sensors and imaging devices to enable precise tracking and targeting of objects moving through a sensor field or past a single integrated sensing and targeting unit. Further, arrays of sensors together with local signal processing are used to trigger cameras and tracking systems, and to provide an alternative location capability for improved robustness. The system is self-configuring and remotely controllable, and enables remote systems and operators to query for collected data, including sensory and image data, and control the system in response to the collected data.
