TimeScan: A Scalable Wireless Imaging Sensor Network

Wireless automated threat detection networks currently concentrate on non-imaging technology such as acoustic, seismic, and magnetic data. This proposal details our innovative “TimeScan” solution to fully enable video imaging devices to become a powerful yet economical addition to the arsenal of automatic threat detection sensors. Our solution encompasses the end-to-end goal of achieving reliable, high probability threat detection via image processing immediately at the sensor and subsequently at the network base station, with strong consideration for the networking and data distribution in between. With a systems-level perspective, we offer a powerful, practical capability to achieve very low false alarm and very high detection probability via a modular, layered, time-buffered solution that concurrently optimizes in-network data processing, cross-sensor correlation, and communication bandwidth. Modular components yield obsolescence-proof high performance at low cost. Multi-stage processing yields scalability with high system-level threat detection reliability.
