Description

CCTV relies on strategic placement of cameras, and observation of the camera\'s input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.CCTV is commonly used for a variety of purposes, including:

• observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities.Traffic monitoring.
