Prison Camera Reform Act of 2021 This bill establishes various requirements to ensure that the security camera, radio, and public address systems used by the Bureau of Prisons (BOP) have the capabilities necessary to (1) ensure the health and safety of staff and inmates; and (2) ensure the documentation and accessibility of video evidence pertaining to misconduct, maltreatment, or criminal activity within correctional facilities. Among the requirements, the BOP must evaluate the systems currently in use at its facilities and implement a plan that addresses deficiencies in and makes upgrades to the systems.
