SEOUL, Nov. 7 (Korea Bizwire) — Security lights that illuminate dark corners actually prevent theft and crime, according to a recent study.
The Korea Institute of Public Finance released a report Wednesday that examined the number of CCTV cameras and security lights and crimes committed in Seoul between 2014 and 2016.
The results showed that there were 4,500 fewer thefts per 100,000 people when one security lamp was set up. With around 200,000 thefts taking place annually across the country, related crimes were reduced by 2.3 percent.
A security lamp means a light installed in a dark place that is susceptible to crime.
The number of security lights in Seoul stood at 183,163 as of 2016, with the highest number in the affluent neighborhoods of Gangnam, Songpa and Seocho districts.
The installation of CCTV cameras alone did not have a statistically significant effect on the reduction of the crime rate of theft. However, where security lights and CCTV cameras were placed together, the crime rate dropped.
The number of thefts and crimes decreased by 4.7 percent if a CCTV camera was installed at the site where the security lights were installed.
Considering that it costs 12.65 million won (US$10,900) to install and operate a CCTV camera, it would cost an additional 2.5 million won to reduce one theft crime.
As of 2016, 37,883 CCTV cameras had been installed in the city. Nationwide, there are 845,136 units.
“Compared to the independent installation of CCTV cameras and security lights, the combined effect is more likely to reduce the incidence of crimes,” said Jeong Da-woon, an associate researcher at the institute.
