EM system

The electromagnetic system is based on the properties of a magnetic field, i.e. it enables the organising and disorganising of its waves. These properties permit an alarm activation if there is an unauthorised attempt to remove books or other types of media from their designated areas. Special stickers with magnetic strips are used to secure book collections.

Three elements facilitate the proper functioning of the system:

  • using magnetic strips (labels) for book protection.
  • installing a system of anti-theft gateways (detection antennas), at the exit of a library / reading room.
  • activation and deactivation of magnetic strips
