Over the past few decades, surveillance cameras, also known as closed-circuit television (CCTV) cameras, have become widely used by governments, law enforcement officers and private citizens to monitor public spaces, prevent crime and identify criminals. While the millions of surveillance cameras installed worldwide can play a crucial role in the prevention of crime and aid police investigations, they can also considerably restrict the privacy of citizens.

When combined with emerging facial recognition technology, surveillance cameras can become even more intrusive, as they enable the identification, monitoring and tracking of individuals. Moreover, advanced surveillance systems could hinder freedom of speech, by dissuading people from participating in public gatherings or protests for fear of being identified and persecuted.
