Abstract: The Internet provides communication between a server and security officers, supervisors, client representatives, and a security system computer at a client site. On-line access to the server provides integration and management of security system functions such as maintenance of call lists and reports, shift management, and supervision of security officers. The use of the Internet for communication between the server and the client site computer not only provides faster and more reliable communication but also enables the client site computer to request the server to schedule a contingent future event including a need to service a call list unless the client site computer reports a condition warranting the removal of the contingent event from the schedule. For example, the failure of a security officer to visit a check point at a scheduled time results in the server accessing a call list to notify a designated recipient.

Abstract: For tracking a person such as a security guard at a construction site, RF-ID tags are placed at a plurality of locations at the site. The person carries a portable RF-ID tag reader while visiting at least some of the locations, and the portable RF-ID tag reader detects the presence of the RF-ID tags at these locations and reads tag identifiers identifying these locations. The person is tracked by monitoring a sequence of the tag identifiers read by the portable RF-ID tag reader. For example, the person also carries an Internet capable cell telephone that transmits the tag identifiers over the Internet to a computer at a location remote from the site, and the computer detects when the person deviates from an assigned path at the site.
