CCTV might not be something you have heard
before, it’s certainly not something said that often unless
you are in the media/television or security field. But the CCTV
system has been around since the early ‘40s,
when it was first installed in Peenemuende for clearer views
of the V2-rockets. Since then, CCTV systems
have been used for NASA when they launch shuttes or for rocket
flights to catch any glitches or small problems ahead of time.
CCTV means “closed-circuit television”
and is the use of television cameras to transmit a signal to
a specific set of monitors to capture images otherwise missed.
Larger rockets have even been fitted with CCTV cameras
to ensure safety measures are met before having astronauts inside.
The most important part of CCTV is mainly for
detection, not necessarily on preventing the crime. They are
a great security camera.
When criminals are being prosecuted, CCTV images
have quickly and efficiently solved the case. An example of
this was the David Copeland case, where the Soho nail bomber
was captured at the scene of his crimes. Missing children organizations
are using CCTV to track movements of missing
children as well due to the effectiveness of the systems. Other
uses have also been for construction companies outfitting their
vans, trucks and buses with CCTVs so that they
can see at all angles, including when they are driving in reverse
to make sure there are no small items or people in their blind
It’s been said that CCTV was developed
partly due to the IRA bombings in the United Kingdom in the
late 70s/early 80s and since then, it’s been widely accepted
into police stations, government agencies, corporate offices
and even homes. Since CCTV cameras are so widespread, the cost
is in anyone’s budget and it can literally be used for
a business owner or a homeowner.
CCTVs are ideal for surveillance
purposes, especially in areas you think can be a potential target
for theft and vandalism. Many are now wireless cameras and come
in a variety of sizes. These surveillance cameras
are not of the size of the traditional spy camera, but there
size has shrunk as technology has improved. Many public places,
such as airports, casinos, shopping malls and banks have added
CCTV cameras for increased security. They are
also part of many home security systems.
After your have determined your specific needs and how many
cameras you will need to have for your home security
system or for overall surveillance, choose from a standard
CCTV or one that is high resolution. Most come with a fixed
lens but you can always purchase an iris lens or one that is
of higher quality separately. CCTVs are best
used indoors but if you need it for outdoor use, it should work
fine as long as you upgrade the lens and monitors you will be
using to track movement as a surveillance camera.
It’s available in black and white and color but should
not make a difference in quality. There is a CCTV that will
your individual needs.
