"Examining Video Visitation in Prison" reports on a study by the Vera Institute that surveyed the status of video visitation in State prisons in the United States. It examined how departments of corrections use video visits, the cost of implementing and operating such a system, and the benefits and challenges of implementation. It concludes that video visitation can provide a form of face-to-face interaction between inmates and family members when the inmates are housed in a facility a long distance from home or when family members cannot physically visit the prison for other reasons, and it can be available outside of visiting hours required for in-person visits; however, use of this technology can be expensive for families, and connectivity problems can occur.
