The organizing committee for the 2020 Tokyo Olympics will install a state-of-the-art video surveillance system at venues and the athletes' village during the games in a bid to improve the efficiency of its surveillance measures, several sources have said.

According to the sources, the surveillance system, provided by Olympic sponsor Panasonic Corp., combines infrared sensors and cameras. The organizers hope the new system will allow a high level of security despite having venues spread across the country.

Organizers are planning to install some 2,500 sets of sensors and 8,000 surveillance cameras at the Olympics, sources said Friday.
