A system for physical intrusion detection/alarm monitoring comprises: one or more computing devices, comprising processor devices and memory in communication with the processor devices, configured to: - receive, from remote badge reader devices, sensory inputs from credentials or badges, with the reader devices being within a monitored premises; - receive video information from cameras and other image capture devices disposed throughout the premises; - continually correlate the received sensory inputs from the credentials or badges with the received video by determining, from the received sensory inputs, the number of credentials or badges within one or more areas of the monitored premises and determining, from the received video, the number of individuals within the one or more areas of the monitored premises; - apply one or more recognition algorithms to detect the presence of a number of individuals in the received video; - isolate a possible non credentialed individual appearing in the received video by: -. applying video recognition to identify the number of people in a certain area and correlate that data with data from one or more of the remote badge readers to identify the appropriately number of badged individuals in a group of individuals within a monitored area, and by -. continually tracking the credentials or badges such that, when one or more of the tracked credentials or badges and a corresponding number of individuals departs the one or more areas, the system is configured to stop tracking those one or more credentials or badges, while continually tracking any remaining badges or credentials and a non-corresponding number of individuals; and - produce an alert to send to a control center to alert authorities to the location of an isolated non credentialed individual. - receive, from remote badge reader devices, sensory inputs from credentials or badges, with the reader devices being within a monitored premises; - receive video information from cameras and other image capture devices disposed throughout the premises; - continually correlate the received sensory inputs from the credentials or badges with the received video by determining, from the received sensory inputs, the number of credentials or badges within one or more areas of the monitored premises and determining, from the received video, the number of individuals within the one or more areas of the monitored premises; - apply one or more recognition algorithms to detect the presence of a number of individuals in the received video; - isolate a possible non credentialed individual appearing in the received video by: -. applying video recognition to identify the number of people in a certain area and correlate that data with data from one or more of the remote badge readers to identify the appropriately number of badged individuals in a group of individuals within a monitored area, and by -. continually tracking the credentials or badges such that, when one or more of the tracked credentials or badges and a corresponding number of individuals departs the one or more areas, the system is configured to stop tracking those one or more credentials or badges, while continually tracking any remaining badges or credentials and a non-corresponding number of individuals; and -. applying video recognition to identify the number of people in a certain area and correlate that data with data from one or more of the remote badge readers to identify the appropriately number of badged individuals in a group of individuals within a monitored area, and by -. continually tracking the credentials or badges such that, when one or more of the tracked credentials or badges and a corresponding number of individuals departs the one or more areas, the system is configured to stop tracking those one or more credentials or badges, while continually tracking any remaining badges or credentials and a non-corresponding number of individuals; and - produce an alert to send to a control center to alert authorities to the location of an isolated non credentialed individual.
