1. What is CCTV?
CCTV (Closed Circuit Television) is a visual surveillance technology designed for monitoring a variety of environments and activities. CCTV systems typically involve a fixed (or "dedicated") communications link between cameras and monitors.
In the past decade, the use of CCTV has grown to unprecedented levels. In Britain between £150 and £300 million ($225 - $450 million) per year is now spent on a surveillance industry involving an estimated 300,000 cameras. Most British towns and cities are moving to CCTV surveillance of public areas, housing estates, car parks and public facilities. Growth in the market is estimated at 15% to 20% annually.
