The importance of CCTV Camera in investigation cases.
by Vantage Security vantage securityThere has been comprehensive research on the importance of closed-circuit television (CCTV) for preventing crime, but little on its value as an investigative tool. This study tried to establish how often CCTV provides useful evidence and how this is affected by circumstances, analyzing 251,195 crimes recorded by British Transport Police that occurred on the British railway network between 2011 and 2015. CCTV was available to investigators in 45% of cases and judged to be useful in 29% (65% of cases in which it was available).
Useful CCTV was associated with
significantly increased chances of crimes being solved for all crime types
except drugs/weapons possession and fraud. Images were more likely to be
available for more-serious crimes, and less likely to be available for cases
occurring at unknown times or in certain types of locations. Although this
research was limited to offences on railways, it appears that CCTV is a
powerful investigative tool for many types of crime. The usefulness of CCTV is
limited by several factors, most notably the number of public areas not
covered. Several recommendations for increasing the usefulness of CCTV are
discussed.
Although the debate about CCTV has
been both long lasting and wide ranging, empirical evidence on the topic has
so-far not covered all of its aspects. This post strives to provide evidence to
inform one area of this debate about which evidence is currently limited: the
extent to which CCTV is valuable for criminal investigations. The next section
contains a review of the existing literature, followed by an explanation of the
mechanisms that may influence the effectiveness of surveillance cameras in
investigations.
Due to increasing use of CCTV camera
across various establishments, there has been a significant rise in the number
of CCTV camera suppliers in Dubai.
CCTV cameras also have the capability
of creating unintended effects, good and bad. The “halo effect” refers to the
potential for greater security in areas outside the view of cameras; this could
be offset by the “displacement effect,” which pushes antisocial activity to
other parts of the city. Cameras could also promote a false sense of security
and lead citizens to take fewer precautions, or they could also cause more
crimes to be reported, and thus lead to a perceived increase in crime.
·
Necessity: The use of camera systems must be justified
empirically, ideally by an independent authority. Objectives and intended
outcomes must be defined.
·
Proportionality: CCTV equipment must be appropriate for the
problem it is intended to address. Technology should “respond to the
established objectives, without going further.” Data should be protected and
the length of time it is retained be clearly defined.
·
Transparency: Citizens should know what the objectives of a
CCTV system are, what its installation and operational costs are, the areas
being surveyed, and what the results are. Reports should occur regularly so
citizens can make informed decisions.
·
Accountability: Those in charge of public CCTV systems should
be clearly identified and accountable to the public, whether the systems are
run by the government or private firms.
·
Independent oversight: An external body should be charged
with ensuring that systems respect the public’s rights and are achieving their
stated objectives. Ideally citizens would have a voice in the oversight
process.
For those looking for reputed CCTV camera suppliers in Dubai, it is necessary to carry
out a thorough research about the local law related to CCTV camera installation
to avoid further inconvenience.
