Telescreens from Orwell’s 1984 meet 21st century technology

In the novel 1984, the telescreens were television and security camera-like devices used by the dictator of Oceania (one of several huge land masses) to prevent anyone in his realm from forming conspiracies with others against the government. These large screens were so sensitive that they could detect your heartbeat! A few privileged people could turn off their telescreens with the understanding they could only be off for 30 minutes or less. No one ever knew how many screens were monitored at any one time or how.

Excerpt from the novel 1984:-

Behind Winston’s back the voice from the telescreen was still babbling away about pig-iron and the overfulfilment of the Ninth Three-Year Plan. The telescreen received and transmitted simultaneously. Any sound that Winston made,
above the level of a very low whisper, would be picked up by it, moreover, so long as he remained within the field of vision which the metal plaque commanded, he could be seen as well as heard. There was of course no way of knowing whether you were being watched at any given moment. How often, or on what system, the Thought Police plugged in on any individual wire was guesswork. It was even conceivable that they watched everybody all the time. But at any rate they could plug in your wire whenever they wanted to. You had to live — did live, from habit that became instinct — in the assumption that every sound you made was overheard, and, except in darkness, every movement scrutinized.

In today’s world, the 1984 telescreens are replaced with “through the wall surveillance” that can pick up slightest sound from nerves and monitor heart rate. Many people will not believe this, unless they see it. Like the 1984 telescreen, it keeps repeating phrases  which mean “we are watching you”. The system is called synthetic telepathy or techlepathy and is part of “through the wall surveillance” system.

Excerpt from 1984:-

The great majority of  “proles” did not even have telescreens in their homes. Even the civil police interfered with them
very little. There was a vast amount of criminality in London, a whole worldwithin- a-world of thieves, bandits, prostitutes, drug-peddlers, and racketeers of every description; but since it all happened among the proles themselves, it was of no importance.
