摘要: A security system uses tags that are able to receive time signals sent from the GPS satellites or the broadcasting radio signals from the cell towers and transmit the identification and location information or signals to the central database and server for triangulation/trilateration periodically or in the event of an emergency. A security system uses tags that are able to transmit RF signals to readers located around a college campus. The tags may transmit signals periodically or in the event of an emergency. Certain locations use LF readers with exciters that trigger a signal from the tag. The security system may provide quick identification and location of individuals in danger.
