US, China use a surveillance camera for every 4-man
One billion surveillance cameras will be deployed globally by 2021, according to data compiled by IHS Markit and first reported by The Wall Street Journal. China's installed base is expected to rise to over 560 million cameras by 2021, representing the largest share of surveillance devices installed globally, with the US rising to around 85 million cameras. When taking populations into account, however, China will continue to have nearly the same ratio of cameras to citizens as the US.
In 2018, China had 350 million cameras installed for an estimated one camera for every 4.1 people. That compared to one for every 4.6 people in the US where 70 million cameras were installed. Taiwan was third in terms of penetration with one camera for every 5.5 citizens in 2018, followed by the UK and Ireland (1:6.5) and Singapore (1:7.1).
China's installed base of cameras has recently risen 70 percent, while the US increased by nearly 50 percent.
"During the past few years, coverage of the surveillance market has focused heavily on China's massive deployments of cameras and artificial intelligence (AI) technology," said IHS Markit analyst Oliver Philippou.
There is a difference in how the cameras are implemented, though. In China, most cameras are installed for the purposes of widespread video surveillance of cities, whereas cameras installed in the US are primarily for the purposes of retail and commercial usage. Notably, the Chinese government is reportedly using cameras with facial recognition to profile and track.
US cities are split currently on how to deal with facial recognition. As reported by the WSJ, cities like Detroit; Washington, DC; and Orlando are testing it for policing and security, while others, like San Francisco, have officially banned it. IHS Markit says only 3 percent of security cameras installed in the US are for the purposes of city-wide surveillance.
