CCTV systems consist of three components. First are the cameras themselves. Because of technological advances, cameras have many features including the ability to pan, tilt, and zoom. Modern cameras also capture color images (instead of monochromatic black and white) and they also use infrared and ultraviolet technologies that enhance night vision surveillance capabilities. Next, the cameras can send their signals to monitors located at a central location or off-site. Operators at these locations have the ability to control cameras while watching single camera images or multiple cameras that may have their own independent monitors. In most cases, however, there is one main monitor called a multiplexor. Multiplexers have the ability to display one camera image, periodically switch from one camera to another or display multiple images at a time through split screen technologies on a monitor. Personnel also have the ability to determine which cameras to watch at any given time while also controlling the functions of each camera (e.g., pan, tilt, and zoom) from this location. These systems can also attach peripheral devices (devices that have one single task) such as sensors and alarms that may have the capacity to directly activate the camera on the multiplexor where the threat is detected. Last, most CCTV systems also have a recording device that has the ability to record all of the cameras for future playback, and to preserve footage for use in investigations and criminal and civil complaints.
