How effective are CCTV security systems in reducing crime?

Since the July 7 London bombings, CCTV (Closed Circuit Television) security systems around the world have been scrutinized with increased scrutiny and with greater expectations of crime reduction. Although not a panacea for crime prevention, many CCTV surveillance systems have been successful in reducing some types of crime such as property crime, acting as a deterrent in car parks or other public places and making citizens aware feel safer. However, the results are mixed when violent crimes are addressed and when the crimes involve alcohol.

In the UK, where the average person may be monitored 300 times a day by the prevailing closed-circuit television systems, Britain’s Home Office has used numerous case studies combined with crime statistics to determine the effectiveness of these systems. of CCTV and to see how well CCTV saves time and money for your police force. In fact, between 1999 and 2001, the British government spent £170 million (approximately $250 million) on CCTV security schemes in towns and city centres, car parks, crime hotspots and residential areas.

Keys to evaluate CCTV systems

According to Coretta Philips of the Home Office Crime Reduction and Surveillance Unit, CCTV systems are assessed using these identifiers that help police identify where and when CCTV security camera systems are most beneficial.


oh
caught in the act — When would-be criminals fear being caught on CCTV cameras for legal purposes, they often abandon any idea of ​​committing a crime.

oh Advertising — If CCTV camera schematics are public knowledge, then would-be criminals may leave the target area, but may go to another area. Data from the Ministry of the Interior found that in the days before the CCTV system was activated, crime decreased due to increased advertising. However, if the CCTV system is advertised privately, offenders are more likely to be discouraged because they may think that CCTV security cameras can monitor other areas as well.

oh Effective deployment of law enforcement officers — CCTV systems increase the response time of police officers to the scene of an incident before a member of the public has to call the police. Based on data collected in 2004 by the Ministry of the Interior, CCTV operators can determine how many officers to send to the scene, and CCTV surveillance cameras can tell what criminals are doing on the scene before the police arrive.

oh time for crime — If criminals think they can complete their crime before CCTV systems can record it, then the police will have less chance of catching criminals. For example, if car thieves know that the security camera’s angle, range, and speed are limited, they could determine the best way to avoid CCTV security cameras. However, CCTV data from the Home Office has shown a reduction in carjackings in car parks, revealing that some criminals may still be caught on camera despite the speed of crime.

Where CCTV systems performed well and where they failed

Although CCTV systems appear to reduce and deter property crime in public areas, such as parking lots or shopping malls, CCTV systems are not as effective in stopping or preventing violent crime. Although CCTV systems help deploy police officers quickly to these violent crime sites, security cameras can be avoided by criminals, since security cameras are mounted in public areas, where violent crime does not occur. In this case, better street lighting can help prevent these violent crimes from occurring. Additionally, when it comes to alcohol, criminals do not consider the consequences of their actions, making CCTV systems ineffective in deterring intoxicated criminals.

On a positive note, CCTV systems reduce the public’s fear of crime and ensure rapid deployment of officers to the scene of an incident, giving criminals less time to act more violently. To really verify whether the CCTV system is effective, the law enforcement agency needs to conduct video surveillance evaluations over a long period of time to eliminate any inconsistencies in the crime data. Also, if the CCTV operators are well trained and know the quickest way to deploy police officers, then the CCTV system will be more effective. CCTV systems are the future of crime prevention and as CCTV security cameras become more sophisticated, more criminals will be caught and more crimes prevented.
