Closed-circuit television (CCTV) is a system of formal surveillance which uses cameras on a closed circuit (not connected to outgoing cables) to either aid or replaces security workers. Professionally installed CCTV systems can be used in homes, businesses and public places to improve the safety and security of property, identify perpetrators, prevent crime and to assist with public crowd control situations.
Proven Effective in Reducing Crime
Two thorough reviews of 41 carefully selected studies on CCTV and its effectiveness at reducing and/or preventing crime definitively showed that CCTV was able to reduce criminal activity. The scientific evidence of CCTV’s efficacy as a crime reduction tool, however, does vary depending on the specific situation, type of crime and location. Research has shown that while CCTV can reduce most types of crime, it most effectively lowered property and vehicle crime rates, especially in parking lots. The study reviews provided no evidence regarding CCTV’s effect on violent crimes.
How Does the Presence of CCTV Work to Prevent Crime?
All CCTV truly does is provide the ability to watch an area or building while also creating the perception in individuals that they are, in fact, being watched. Although this might not seem like it would be enough to deter would-be criminals, the research says otherwise. So, how exactly does CCTV dissuade criminals from following through with their lawless plans? Several ideas have been posited as potential mechanisms of CCTV. These ideas include:
- A CCTV presence might increase a would-be criminal’s awareness of the risk of getting caught.
- In addition to perceived risk, CCTV actually does increase the chance that a criminal will be caught.
- The public might respond to the presence of cameras by taking increased precautions with their actions and choices.
- The presence of security cameras can signify the improvement of an area, increasing feelings of community pride.
- CCTV might also create a sense of security, encouraging public use of an area and increasing traffic (also increasing informal surveillance).
- Security cameras also bolster the effective and timely deployment of security professionals to incidents.
Although it is unclear exactly how and why the presence of security cameras deter crime, it does not change the fact that installing CCTV surveillance does prevent criminal activity.
