Not all library security systems are the same. They have varying hit rates (tag detection) and as with any alarm system, means of beating them. Having worked with many types of library security systems (both electromagnetic and radio frequency) we strongly believe the Certus® system to be the best in both regards.

Certus® library security systems are fully compatible with 3M™, Tag-Alert™ and Knogo® systems. This means that if you are upgrading from an existing 3M™ system, there is no need to re-tag your entire collection.

Certus® library security systems are high quality systems manufactured in Germany, use the most modern electronics, have self-adjusting microprocessors and have slim and durable panels with the option of clear Plexiglas® finish, thus allowing the panels to be non-obtrusive while providing an excellent level of security for your library.
