The report describes the methodology used to obtain information on technological developments in correctional institutions. Data presented from the findings of a survey of State and Federal departments of corrections describe the procedures and criteria used in the selection of various technological systems for use in correctional institutions. This includes a summary of newly opened institutions or those currently under construction. Data from a survey of correctional institutions built or renovated within the past 10 years describe the types of technological equipment being used in correctional facilities in the areas of perimeter security, locking, internal surveillance, internal security, communications, fire safety, and management information. The data also provide an overview of satisfaction with technology and the impact of technology on the operations of correctional institutions. Case studies of correctional institutions examine some of the most recent technologies being used.
