Abstract:
Sensing-holes in PIR-based motion detection systems are considered, and their impact on occupancy monitoring
applications is investigated. To our knowledge, none of prior works on PIR-based systems consider the
presence of these holes, which represents the major cause for low precision of such systems in environments
featured with very low mobility of occupants, such as working offices. We consider optimal placement of
PIRs that ensures maximum coverage in presence of holes. The problem is formulated as a mixed integer linear
programming optimization problem (MILP). Based on this formulation, an experimental study on a typical
working office has been carried out. The empirical results quantify the effects of the holes on the detection
accuracy and demonstrate the enhancement provided by the optimal deployment of the solution.
