Privacy Sensitive Monitoring With a Mix of IR Sensors and Cameras
Abhishek Rajgarhia · 2004
Consider an installation which has an entrance and various private areas. The goal is to monitor the private areas to assist in prosecuting theft afterthe-fact. Sensor nodes are equipped with cameras and PIR sensors. For privacy reasons, cameras are not deployed in private areas, however, they are considered acceptable for the entrance. Private areas have only PIR sensors, able to detect the presence or absence of a human. We assume sensors are deployed densely enough that a human moving through the sensor field triggers multiple sensors.
