Whether installed on private properties, commercial spaces or business premises, these numerous CCTV systems would have been installed with two primary operational uses in mind — to deter and to secure. CCTV facilitates these by: Being a visible presence and therefore deterrent on properties; Being available as a monitored service, for speedy response in the event of problems; By recording footage as evidence; By securing criminal convictions in the case of CCTV evidence provided being effective in court.

CCTV can be viewed as part of: CCTV then, has the ability to simultaneously intrude and protect. Whether it protects at the expense of people's civil liberties Does the Effectiveness of CCTV as a Crime Prevention Strategy Outweigh the Threat to Civil Liberties? Effectiveness of CCTV in Crime Prevention - Peterson Kelly - Essay - Information Management - Publish your bachelor's or master's thesis, dissertation, term paper or essayPages: 5. on the effectiveness of CCTV on crime, searches of bibliographies of CCTV reports, and contacts with leading researchers. Forty-four studies met the inclusion criteria.

On the one side, you have a number of studies and leading thinkers who clearly contend that CCTV systems are ineffective. On the other, you have numerous municipalities who are weekly green-lighting new CCTV projects. A directory of the 20 top papers in the field are included at the end of this document.

This report is based on those papers. Key Findings Summary The expectation that CCTV systems should be deployed to reduce crime rather than solve crime has created huge problems. The general approach is to take current crime statistics for a region and compare those statistics to the period after installation of CCTV.

A number of techniques are used to adjust to control for general changes in crime and to track displacement or diffusion of benefits to other areas. Nevertheless, the focus of all quantitative analysis has been on reducing crime.

This is the mirror opposite of the private sector. In the private sector, the overwhelming majority of CCTV systems are justified by their use in solving crime.

It is investigations where most private businesses find value and return in their CCTV systems. For businesses, only a very small percentage of CCTV cameras are ever even watched.

The systems pay for themselves by periodically being able to identify or prove a criminal activity. This indicates a failure of expectations for public CCTV systems.

CCTV: effective is subjective

By contrast, the focus on public CCTV effectiveness being determined on reducing crime sets a dangerous expectation that is difficult to achieve and likely to create dissatisfaction within the community.

The problem seems to be the fault of the original advocates of these systems, rather than a deficiency of the testers. The academics and researchers performing these tests were reacting to the expectations that the proponents of these systems made originally.

In the recommendations section, I will examine how we can move beyond this unproductive and problematic situation. This often has turned the issue into an all or nothing debate.

The testing has also focused on the general impact on crime reduction but notable attention has been paid to different types of crime. The most frequently cited example is the ability to reduce thefts in parking lots. By contrast, the same studies widely agreed that CCTV demonstrated little or no affect on reducing crimes of passion.

Incidents like public drunkenness or acts of rage generally did not seem to be affected by the presence of CCTV cameras. This fits a broadly accepted rational actor model and the effect that CCTV cameras has on rational actors.

Since CCTV cameras increases the risk that a criminal will be prosecuted for a crime, the criminal will respond accordingly. Rather than engage in political debates over the issue in general, we should use this more nuanced knowledge to optimize our use of CCTV. The rest of the studies do not even discuss differences in technology available.

I do not fault them as the evidence available is limited to even conduct such a test. Nevertheless, differences in technology can make an extreme difference. The studies cover a very broad time period. The oldest study I found was from with most of the studies available being performed in the period from — The problem is that CCTV technology has experienced a dramatic transformation in that time period.

This is somewhat similar to the type of change experienced with mobile phones going from big, bulky, limited and expensive to slim, powerful and ubiqutious. It is quite unfair to assess the question is CCTV effective, in any form, without factoring in the differences in the type of technology used.

The examples found in the studies were fairly shocking compared to today's mainstream CCTV systems. The clear majority of systems employed in the studies used VCRs.

Even when systems used DVRs, most were recording under 2 frames per second. All of the systems used standard definition cameras.

While none of the reports discussed the type of transmission systems, given that almost all the tests were from or earlier, it is extremely likely none of them were using IP networks for transmission.Effectiveness Studies.

Earlier research in the UK (pre st century) The United Kingdom experienced a sharp increase in the presence of closed-circuit television (CCTV) surveillance cameras starting in the s.

The effects of CCTV on Crime What Works Briefing 8 Overview: The review finds that use of Close Circuit Television (CCTV) can lead to a small reduction in crime.

CCTV cameras also have the potential 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.

effectiveness of cctv in crime prevention Closed-circuit television utilizes video cameras in surveillance of a particular area using a limited number of surveillance monitors. Almost all video cameras fit in the usage as the CCTV cameras, although the ones used must have high definition for accuracy in monitoring mainly in banks, supermarkets Pages: 5.

The effectiveness of CCTV and improved street lighting has been studied extensively in terms of their potential for reducing the number of crimes in a certain area.
