"An alarm system detecting gunfire would automatically alert authorities to a live incident. It would remove the need to make emergency calls in the first place, cutting response times by several minutes and saving lives in the process," the Greater London Authority's Conservative crime spokesperson, Roger Evans, was quoted as saying by The Telegraph.
Evans, along with other Greater London Authority politicians, proposed the installation of the detectors in 50 public buildings including train stations, shopping centers, museums and hospitals without disclosing the list of those places, the newspaper reported.
The price of the equipment should range from 13,000 to 65,000 pounds ($20,000 to $100,000), bringing the cost of the pilot project to about 3 million pounds, according to The Telegraph.
Similar equipment is already in use in public buildings, including schools, in the United States.
Earlier in January, UK Home Secretary Theresa May said that the country's terrorist threat was at a high level. It was raised after the terror attacks against French weekly magazine Charlie Hebdo, in which 12 people were killed.
