Abstract
Abstract A security monitoring system including one or more cameras for monitoring a path of an individual, a recorder for recording the monitoring of the individual, trajectory analyzer for computing a trajectory of the path of the individual from the recorded monitoring, comparator for comparing the trajectory against known trajectories, and an alarm system for transmitting an alarm signal if the trajectory does not match one of the known trajectories. Further, the system may include a database for storing image data for each authorized individual of the structure and a recognition system for comparing images of the individual from the one or more cameras with the stored image data in the database. The alarm system transmits the alarm signal if the trajectory does not match one of the known trajectories and the individual is an authorized individual or if the individual is not an authorized individual.
