Camera surveillance has many names and is often called TV-monitoring, video surveillance, CCTV (closed Circuit Tele Vision), ITV (Internal TV) or simply surveilance.
The use of CCTV as part of the electronic surveillance is becoming more and more common in many places - right from very large companies to smaller homes. This is because th eCCTV provides security for customers / Staff / residents and minimize the risk of burglary and theft. If theses thing happen anyway, then CCTV - in many cases - help to solve the crime e.g. by capturing license plates and pictures of the crime.
CCTV in combination with alarms and access control provides a more optimal electronic security.
