Performance Analysis of Analog Passive Detectors in Target Tracking Wireless Sensor Networks

The development of surveillance systems for indoor and outdoor environments using currently available wireless sensor technology without violating privacy issues is a challenging task. Passive Infrared (PIR) detectors are suitable for such systems provided solutions to the technical limitations are implemented. In the proposed work, the development of a human tracking system using analogue PIR detectors and currently available wireless sensor technology is presented. Performance is evaluated by conducting real-time tests in different environmental scenarios. Analysis of experimental results of human sensing signals indicates that performance is affected by environmental parameters. These findings will be helpful for the researchers while implementing a real-time system in the field
