US Patent 7990279 Emergency ingress/egress monitoring system

A system to monitor the entry and exit of individuals from a facility and to identify individuals who safely evacuated the facility and those who have entered, but apparently have not safely evacuated it and indicated safe evacuation by use of a card reader or similar device at an emergency reporting area. The system also indicates the most likely area of a facility in which an individual may be found. Such census information is made available to emergency workers and is of significant value in rescue efforts following facility evacuations. A modification of the systems allows an attendant to monitor the entry, exit, and re-entry of individuals traveling in two or more vehicles following stops. Finally, the system includes a head count census of individuals entering large facilities in which individual identity is effectively impossible to follow and a head count census of individuals evacuating the facility identified by specific parts of the facility.
