A CCTV, or closed-circuit television, surveillance system transmits the feed of its connected security cameras to a specific location. The network of security cameras makes up a complete system and the signals are not publicly distributed to outside receivers. A CCTV system functions with strategically-placed security cameras and human monitoring of the cameras’ video feeds on an internal system of monitors. Video feeds may also be recorded on a separate digital video recorder, or DVR. If the DVR is connected to the internet, remote viewing of video footage may also be available. CCTV is an older system that has developed and modernized, adding new features throughout the years.
CCTV cameras are most often used in business or government settings, or for monitoring large areas such as retail stores, banks, and other institutions. They are often seen surveilling various public areas in cities, such as parks and highways. Law enforcement professionals often use them to monitor public behavior, traffic patterns, and more, to help secure public safety.
