http://www.symetrix.com.au/cctv.html Closed Circuit Television Cameras or even popularly known as CCTV cameras are used largely just for surveillance and monitoring functions. They take as well as document videos and images of what occurs inside of a particular place live. The videos and images afterwards are transported towards a screen or perhaps set of screens as well as recorded on tape or even on a digital recording device. CCTV security cameras can be set to monitor a particular area or perhaps they may be handled individually.
