Although closed-circuit television (CCTV) surveillance cameras are used widely for security, such use is questionable. The British government has stated that CCTV is essential to Washington, DC’s Metropolitan Police Department Porter 2016 (February 2007), and police investigations are often considered “very valuable.” On the contrary, the campaign group (Liberty 2016) said that the widespread use of CCTV “threats to our way of life” and “widespread visual oversight could have a negative impact on freedom of speech and activities” He said. Similarly, the US Civil Liberties Union has argued that public CCTV surveillance provides “the possibility of being able to effectively abuse the Orwellian style of surveillance” (Steinhardt 1999).

You Can’t Escape

The debate over CCTV is resilient and extensive, but scientifically on this issue, it does not include every aspect. What evidence is there to prove that that CCTV is a very important area of ​​criminal investigation? The latest evidence is very limited but there are many claims that journalists and investigators find CCTV an effective tool to pursue criminal cases. What are the mechanisms that may affect the effectiveness of surveillance cameras in existing research? There’s a data presented in the UK Railway Cybercrime Report survey that shows the effectiveness of the use of these cameras in research.

Although there has been extensive research on the value to compare Arlo, Ring and Nest for crime prevention, there is no value as a research tool. The survey examined the frequency and impact of useful CCTV evidence and analyzed 251,195 criminal cases recorded by the British Traffic Police between 2011 and 2015.45% of respondents can use CCTV, 29% (or 65% if effective). Favorable closed-circuit television has greatly improved the likelihood that all types of crimes other than drugs and weapons possession and scams will be resolved. Images are more likely to be used for more serious crimes and are less likely to use images when they occur at unknown times or in certain types of places. Although this investigation is limited to railway crime, CCTV appears to be a powerful research tool for many crimes. The use of CCTV is limited by a number of factors, particularly the number of public places of interest. Some suggestions for increasing the usefulness of CCTV are discussed.
