ILS Intelligent Sensor
The ILS Intelligent Sensor (exit gates) provides security at library exits and corrals by
generating a radio field that gathers circuit information from a distance up to 24 inches
(61 cm). Two intelligent sensors form a secure aisle up to 48 inches (122 cm) wide for
circuit detection range. Additionally, the sensor communicates back to the Library
Management System via the Intelligent Library Controller in real-time, determining
whether an item has been checked out. If items in the interrogation field are not properly
checked out, an alarm sounds and the book title appears on an exit alarm screen.

Local Security Controller
The Local Security Controller (LSC) is a combination hardware and software solution for
a single server, multi-branch ILS deployment. The LSC assists the Intelligent Library
Controller in maintaining the response speed of Intelligent Sensors (exit gates), managing
the connection between the Exit Interrogators at the branch and the remote Application
Server to provide maximum caching performance. The LSC also enables the exit gates to
operate (with limitations) if the main server is down. This scenario is normally used with
libraries containing up to 20 branches.
