The Department of Homeland Security (DHS) and its components deploy a number of Closed-Circuit Television (CCTV) systems throughout the department (See Appendix for detailed list). DHS’ CCTV systems are used to obtain real-time and recorded visual information in and around federal worksites and facilities to aid in crime prevention and criminal prosecution, enhance officer safety, secure physical access, promote cost savings, and assist in terrorism investigation or terrorism prevention. DHS conducted this Privacy Impact Assessment (PIA) because these systems have the ability to capture images of people, license plates, and any other visual information within range of the cameras. This PIA replaces existing CCTV PIAs: those PIAs will be retired with the publication of this PIA and are listed in the appendix. July 18, 2012.
