MOVING THE WORLD WITH INTELLIVATOR® TECHNOLOGY - Integrated CCTV Surveillance System
Closed Circuit Television, in short CCTV, is the use of video cameras to transmit signal to a specific, limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point wireless links. CCTV is often used for surveillance in areas that need monitoring such as traffic monitoring, car park or traffic barriers, restricted rooms or premises, banks, casinos, airports, military installations, residential areas, gated community, apartments, condominiums, clubs, libraries, schools, universities, colleges, stock or store rooms and convenience stores, etc. In industrial plants, CCTV equipment may be used to observe parts of a process that are remote from a control room, or where the environment is not comfortable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.
The first CCTV cameras used in public spaces were crude, conspicuous, low definition black and white systems without the ability to zoom or pan. Modern CCTV cameras use small high definition colour cameras that can not only focus to resolve minute detail, but by linking the control of the cameras to a computer, objects can be tracked semi-automatically. For example, they can track movement across a scene where there should be no movement, or they can lock onto a single object in a busy environment and follow it. Being computerised, this tracking process can also work between cameras.
