Computer systems are used for training, access control, property control, security administration, investigations, recordkeeping, scheduling, and administrative tasks. Security personnel training is provided through a blend of custom-made videotapes and software. The videos provide the new officer with a basic understanding of the style and type of security at the company and overviews of the training process. The officer then learns how to operate an Apple Macintosh computer through a training software package. The trainee next continues training with the computer system, using three, automated software packages in a 5-day program. The security organization operates through the use of four file servers, each on an individual secured network called a local area network. These file servers allow various aspects of the department to operate independently yet with flexibility and control. The file servers are set up in four platforms: property control, security operations, security administration, and card access/alarm systems. An officer at a computer terminal in a lobby has available information on access control, property control, and general security procedures (plant protection procedures, phone directories, MicroMail, passdown log, and vehicle registration).
