The Detection Zone
EAS pedestals pick up activated tags in their detection zone. Signals from the transmitting pedestal are re-radiated by the tag to the receiving pedestal. Although the pedestals serve as a warning, transmitters and receivers can also be hidden in exits. Some systems can use only one pedestal to transmit and receive.

Soft and Hard Tags
