A Closed
Circuit Tele Vision (CCTV) is a video magnification system consisting of a
video screen interfaced with a video camera. Video magnification is achieved in
two ways - the electronic conversion from the small camera imager to the larger
display screen and the optical effect of the cameras zoom lens. The CCTV system
provides high contrast, inverse video display, gray scale, false colours,
natural colours, and / or control of contrast level and brightness. A CCTV is a
video camera connected to a monitor. The camera usually has a zoom feature,
which allows the user to magnify anything placed in the camera’s view.
Application in industrial security.
CCTV is
the most effective security system for use with security organizations. It can
be used in all security functioning and many be hooked up with other devices
also. However its adoption in developing countries is rather slow due to the
higher costs as compared to the other systems. The true scope for applications
is almost unlimited.
Some
examples are listed below:
o Monitoring traffic on a bridge.
o Recording the inside of a baking oven to find the cause of
problems.
o A temporary system to carry out a traffic survey in a town
centre.
o Time lapse recording for the animation of plasticine
puppets.
o Used by the stage manager of a show to see obscured parts of a
set.
o The well-publicised use at football stadiums.
o Hidden in buses to control vandalism.
o Recording the birth of a gorilla at a zoo.
o Making a wildlife program using a large model helicopter.
o Reproducing the infrared vision of a goldfish!
o Aerial photography from a hot air balloon.
o Production control in a factory.
The list
is almost endless and only limited by the imagination.
In all
the industries, it is not only the interior security system which matters, but
management of exterior security system is equally important. Generally all the
treats and other unlawful activities start in case there is laxity in the
exterior security set up. To counter possible threats there are number of
electronic and mechanical capabilities of industrial security will be enhanced
to greater extent.
