What is CCTV’s primary function?

CCTV is most commonly used for surveillance.Security Cameras are now universally featured in many public and private institutions, from a correctional facility to the convenience store. In prisons, reduce the costs of staffing and operating observation towers and make it possible to maintain a constant watch on all areas of the facility. CCTV has become so much less expensive over the years that both large and small stores are able to install cameras as a deterrent against theft and robbery, a practice, which municipal authorities have adopted as a way of curtailing crime in public housing and even on city streets. In many areas of the country as well as in Europe, Security Cameras have been placed in highly crowded public areas as a security measure against terrorism.
