In 2003 TDK Systems Group, Inc. provided project management, integration services and installation of computer systems related to the upgrade of Compass 3E Software to the most current 4E platform.  TDK also completed the installation and checkout of all existing and new security and access control field devices. The project included installation of a Security Management System Server, Video Badging Workstation, Monitoring Workstation, and an Administrative Workstation. The upgrade included the replacement of more than 200 Weigand proximity readers with contactless smart card readers consistent with those recently installed at more than 47 other State facilities. Additionally, TDK's scope included integrating the existing CCTV system matrix switcher with the 4E platform to facilitate alarm call-up function throughout the facility.
