The history of CCTV
13 February 2017
Now a common item of street furniture, it can feel as if CCTV
has been around forever. However, the history of video recording technology is
relatively short. The first instance of CCTV was seen in 1942, when Siemens AG
installed it in Nazi Germany to observe the launch of the V-2 rockets. Back
then, the systems were simply a way of seeing an image, with no way to record the
footage or store the information.
In the 1970s when VCR technology became available, it made
it easier for the footage to be recorded and erased and so CCTV became more
The technology improved further in the 1990s with the launch
of digital multiplexing, which meant that several cameras could record at the
same time. Time lapse and motion sensitive recording also became available.
Nowadays, statistics from
2016 suggest there are 350 million CCTV cameras worldwide, with 65% of
those in Asia.
The systems of today
The CCTV systems that Touchstar ATC provide offer a
wide-variety of modern technological advances. These include instant playback
allowing people to instantly rewind and view footage in the event of an
incident, round-the-clock monitoring with digital footage storage devices and zoom
functions so cameras can focus in on suspicious activity. Furthermore,
simultaneous multiple views enable uninterrupted transmission to monitoring
centres regardless of distance, weather or environment and high quality maximum
image definition irrespective of lighting conditions.
Our systems can also integrate into any other security
systems you may have, including alarm management systems, remote access control
and live audio warning systems.
The benefits of using CCTV
A study conducted
in 2009 by the University of Cambridge looked at the ways in which CCTV has
led to a reduction in crime in some of the major cities around the world. The
key finding from the research was that CCTV is most effective in car parks, where
crime fell by half when a CCTV system was in place.
Many businesses use CCTV as a deterrent to crime and as an
added security system. When an incident does happen, CCTV recordings are
frequently used in prosecutions as visual proof of what has taken place.
Case study: Aston University
We installed a high-definition system to enhance the CCTV
network in place at Aston University in Birmingham as maintaining student
safety is one of the University’s main duty of care.
Rather than replacing all the existing hardware, we deployed
a HD solution - a key advantage of which was the ability to easily remove the
analogue cameras and install 25 new full-HD cameras, while still utilising existing
camera housings. The addition of several extra camera positions extended
external coverage by approximately 25% and with plug-and-play simplicity, the
system was easy to set up, connect via power over Ethernet and configure for
optimal performance, combining high image quality with no visible latency.
Intuitive software now enables the housing team to remotely monitor camera
views with ease from the desktop or remotely via iPhone or an Android device.
