Body scanners are used to screen for contraband in a variety of places. Airports, schools, government buildings, and corrections facilities are examples of the types of places that have employed body scanners. Different types of body scanners have different capabilities based on the imaging technologies used and the sophistication of the internal system analysis. Metal detection was one of the first technologies developed to identify metallic objects on a person, but contraband can take many other forms, such as powders (e.g., drugs), paper (e.g., money), and even ceramic or plastic weapons. Correctional facilities in particular are faced with various forms of contraband, and with elaborate methods of evading detection employed by the local population. Manufacturers have responded by producing scanners that are able to detect nonmetallic contraband, as well as systems that can detect contraband inside body cavities. This report identifies commercially available body scanners and discusses the technologies used by these products. Technological limitations pertaining to the type of materials detected and/or the ability to detect contraband inside body cavities are discussed.
The National Institute of Justice (NIJ) Sensor, Surveillance, and Biometric Technologies (SSBT) Center of Excellence (CoE) has undertaken a best practices report of through-the-wall sensor (TTWS) devices for operation by law enforcement and first responder agencies in the United States. These devices use a form of radar to detect movement behind barriers. The ability to sense the presence of individuals through common building materials can be useful during rescue operations, law enforcement operations and other tactical scenarios. This report provides advice, tactics and information related to the use of TTWS in operational settings. The information provides law enforcement individuals and organizations with a better understanding of the capabilities and limitations of available TTWS equipment. When put into practice, an agency can make the most of the technology and improve the outcome and safety of operational scenarios in which it is deployed. The best practices report focuses on the use of commercially available TTWS devices suitable for law enforcement or emergency response applications.
