Gateways / Antennas are installed at the store entrance and they work with Acousto-Magnetic (AM) technology or with Radio-Frequency waves (RF). A system typically consists of two antennas at the entry/exit of the shop premises. However, if there is limited space, it is also possible to install a sigle getaway by choosing a Mono-Antenna.
The system detects any electronic security tags or soft labels that pass by the antenna. When a tagged item passes by the antenna an alarm sounds warning you that a tagged merchandise item is leaving the store without being detached or removed at your checkout counter.
