The organizing committee of the 2020 Tokyo Olympics and Paralympics 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 said Friday.


According to the sources, the surveillance system, provided by Olympic sponsor Panasonic Corp., combines infrared ray 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 on installing some 2,500 sets of sensors and 8,000 surveillance cameras at next year’s Games, sources said.


When sensors detect an irregularity, footage from a camera at that location will appear on monitors at the local security office as well as the main security center that will oversee the entire Games.


The total number of security cameras in 2020 will outstrip that of previous Games because of the number of venues. The organizers hope the sensors will reduce the workload and the number of security personnel needed.


According to the sources, the organizers are also planning to equip some security guards with wearable cameras to be able to monitor scenes in real time.


The Tokyo Olympics are scheduled to be held between July 24 and Aug. 9, followed by the Paralympics from Aug. 25 to Sept. 6.
