Electromagnetic Technology

University of Aberdeen

How does Electromagnetic (EM) Technology work?

A metallic strip is hidden inside the book or affixed to the CD/DVD. The strip can be activated or deactivated during check-in or checkout. If an item that has not been desensitised is taken through a detection system it will cause the system to alarm.


Why choose EM technology?

EM strips are discretely hidden and are therefore resistant to tampering and difficult to remove. The detection rate of EM is more reliable than other security technologies, as it is less affected by environmental and human factors for example it is unable to be shielded by the human body.

Providing the highest level of security, electromagnetic systems are the preferred choice for libraries with high value collections.
