Surveillance cameras with the ability to measure a crowd’s “mood” and track the number of people by counting cell phone frequencies were deployed at the Lesbian and Gay Mardi Gras Parade on Saturday in Sydney, Australia.
The CCTV technology from the Dynamic Crowd Measurement firm was used to monitor Oxford Street in Sydney as the city’s LGBTQ-themed Mardi Gras parade was held for the first time since 2019, having been cancelled for the past three years due to the Chinese coronavirus.
According to a report from the Sydney Morning Herald, the cutting-edge cameras came equipped with the ability to track the mood of the crowd, with software being able to track facial expressions and determine whether they are displaying signs of happiness, anger, or neutrality.
The cameras also come with the ability to measure crowd density by counting the number of cell phone frequencies emitted in a given area. It was estimated that around 12,000 people attended on Saturday.
