EAS Library Security Gate: Protecting stories, preserving learning.
An EAS Library Security Gate with an EM system actively protects library collections. This technology effectively prevents unauthorized book removal/Book detection. It uses electromagnetic principles for detection. Each library item receives a special EM tag. This thin, flexible strip often hides within book pages.
Material
These EM security strips are usually made of amorphous metal. They respond directly to electromagnetic fields. Library staff use a deactivation unit at checkout. This device demagnetizes the EM tag. The item can then leave the library freely without incident. If an item with an active (magnetized) EM tag passes through the gates, an alarm sounds. This alerts library personnel immediately to the situation.
Operations
The security gates stand at the library exit. They emit a low-frequency electromagnetic field. If an active EM strip disrupts this field, sensors detect it. This disruption triggers an audible or visual alarm. This process signals an unauthorized exit attempt.
Upon an item’s return, staff reactivate the EM tag. They use a special device for this purpose. This ensures the item is secure for future use. The process is simple and quick for staff.
EM systems offer excellent theft deterrence. They reliably detect magnetic strips. EM tags are durable and reusable for many years. They remain effective even when hidden inside materials. Furthermore, the system works well with stacked items. This is a key advantage for busy libraries. EM technology experiences fewer false alarms. Personal metal items rarely trigger the system mistakenly.
Summary
EM systems are generally cost-effective to implement. Installation is straightforward for technicians. Many systems integrate with other library functions seamlessly. Some gates can count patrons entering or exiting. Others may link with surveillance cameras for added security. EM technology provides a vital layer of Book detection. This safeguards valuable library resources efficiently. Libraries widely adopt EM systems. They remain a popular and effective choice globally.
