EACS's can now be used to protect and track movement and use of all corporate assets. Some systems permit basic card access to trigger selected lighting patterns, control elevators, turn on heating and cooling systems in selected areas, and generate time logs for such services. The scope and size of the EACS data base, together with advanced software, have made a more varied and detailed reporting capability possible. It is possible to access such information as work area, driver's license number, or special skills within seconds. As the power and flexibility of EACS's continue to grow, there will be several levels of integration with other information systems. This will provide greater information about the activity of individuals and their work patterns and enhance control over access to secure areas and files. This in turn, will provide information for a richer array of reports for building maintenance and operation, human resources administration, and asset management. EACS's also can provide sophisticated alarm monitoring and can report on a wide variety of functions and processes. The evolution of EACS's into powerful information handling and digital control systems is contributing to increasing overlap between security and facilities management.
