Spring 2012 Conference
March 7 - 9
Conventional security systems have limitations. For example, in an industrial setting, fence monitoring using video surveillance becomes expensive and inefficient as the area under observation grows to cover several miles in length. In this talk, a sensor network approach to this problem is explored. Using WirelessHART compliant communication nodes and cheap MEMS-based accelerometers, the solution covers recording vibrations locally on each fence section and relaying the readings back to a central computer for processing and detection.
