What are Sallyport doors primarily used for in correctional facilities?

Sallyport doors are primarily designed to control inmate movement within correctional facilities. They serve as a secure entry and exit point that allows staff to manage the flow of inmates in a controlled manner. By utilizing a sallyport, correctional personnel can ensure that one set of doors must be closed before another can open, thereby providing a physical barrier that enhances security. This mechanism helps prevent incidents such as escapes or unauthorized access to sensitive areas within the facility.

In contrast, while privacy for inmates, visual surveillance, and staff communication are important aspects of a correctional environment, they do not directly relate to the fundamental purpose of sallyport doors. Privacy usually involves different architectural designs, visual surveillance points are often enhanced through cameras rather than door design, and communication strategies are typically established through protocols and systems distinct from the physical structure of entry points like sallyports. This focus on controlling inmate movement ensures that correctional facilities can maintain safety and order effectively.
