CCTV is an acronym that stands for Closed Circuit Television. It
is defined as the use of one or more cameras used for
surveillance purposes. It was initially developed to increase
bank security and has since spread to every corner of the
security industry. Home security systems, businesses,
corporations, organizations, and schools are several examples of
locations that implement CCTV Security Systems. When CCTV
cameras first appeared in the public sphere, they were crude,
low-definition cameras that only recorded in black and white.
They were completely simple and lacked even the ability to pan
or zoom. CCTV cameras today are smaller, sleeker, and far more
technologically advanced than the cameras of yesterday. They
produce high quality, exceptionally sharp color images, and have
motion sensors that track movement across an area. They can pick
a person out of a crowd and lock on them, tracing their
movements; they can run at night because of infrared technology.
The possibilities are endless for CCTV, especially as the
technology continues to develop. Closed-circuit cameras are
often used to discourage and deter crime. While they don't
necessarily eliminate crime, closed-circuit cameras do make it
possible to identify events and suspects, making is easier to
detect and prosecute those involved in a crime. Another function
that closed-circuit cameras serve is that of traffic monitors.
Speed cameras are installed in various locations, taking a
picture of your license plate and with the help of radar
technology, recording your speed. In many cities in the US, you
may receive a speeding ticket with a picture of your car and its
clocked speed, or a picture of the exact moment you ran a red
light. They come in all shapes and sizes and can be installed
anywhere, from your car and your handbag to police surveillance
vans and taxis. They are ideal for purposes of security as they
have the ability to recall events in real time at an accurate
date and provide information that may lead to the detection and
persecution of criminal activities. Emerging technologies will
make faster, quicker cameras that will be able to pick a face
out of the crowd on command. They could be programmed to
identify 'criminal' behavior by body movement that might signify
a troublemaker, and zoom up on your face in an instant. Banks,
hospitals, institutions that deal in large sums of money,
government buildings, and schools are several areas of the
public sector where closed-circuit television cameras work well.
The CCTV System is moving towards a completely computerized
monitoring system that will eventually replace the current need
for a CCTV operator and become a fully automated system.
