Telescreen

Telescreens are devices that operate simultaneously as televisions, security cameras, and microphones. They are featured in George Orwell's dystopian 1949 novel Nineteen Eighty-Four as well as all film adaptations of the novel. In the novel and its adaptations, telescreens are used by the ruling Party in the totalitarian fictional state of Oceania to keep its subjects under constant surveillance, thus eliminating the chance of secret conspiracies against Oceania.

The concept of telescreen has been discussed as a metaphor or allegory for the loss of privacy in totalitarian states, as well as in the modern era in the context of Internet- or cellular-based devices that allow people to collect audiovisual data, often without their explicit will or knowledge.
