A modern digital CCTV security system consists of hardware and software components that collect and transmit vital surveillance camera information over fiber optic lines to control rooms staffed by security professionals and equipped with digital CCTV monitors. An example of the surveillance cameras used for reducing crime in LA's MacArthur Park include Day/Night 25X cameras equipped with removabl

e infrared cut filters, 25x optical zoom lenses, 12x digital zoom capabilities, and 360-degree PTZ (pan tilt zoom) capabilities. This MacArthur Park system also includes DVRs (digital video recorders) and keypad controllers. DVRs are capable of saving CCTV data to a PC for up to ten weeks of recording and some even feature motion detection technology, which means that the footage is only recorded when motion triggers the DVR system.
