CCTV stands for Closed-circuit television and CCTV cameras are mainly used for security surveillance. CCTV cameras can be either video cameras or digital still cameras. The video cameras are usually used for video surveillance of houses or business places. The digital still cameras are used for traffic surveillance.
Some CCTV digital video recorders can record audio but it depends on the system and how it has been installed. Installations near busy roads, in restaurants and bars often do not have this facility whilst those in banks and offices may have it.
