Security: camera technologies

Surveillance and Security. The ability to use camera technologies to track and identify the movements of individuals or intruders often relies heavily on images. Photographic evidence can be used in court as proof of wrongdoing. 

Cinematography also has important applications in the security industry. Both private security firms and public agencies make use of closed-circuit television (CCTV) technology—a system in which the video imaging signals from one or more cameras are transmitted to a restricted set of monitors—to keep a continuous record of what takes place in businesses such as banks, convenience markets, and hospitals, and public areas with a high record of criminal activity.
