* The first half of ''PastwatchTheRedemptionOfChristopherColumbus'' is about two such devices. The first one was of limited use and wasn't precise enough to show people (they were seen as fast-moving shadows), but it did allow the researchers to see architecture and the like. Later, a more focused device was created, allowing very detailed images and sound to be shown. Fashions of the past became all the rage throughout the recovering world. Researchers had to learn ancient languages in order to understand what the people on the screen were saying. One case even had a PokeInTheThirdEye moment. When viewing the life of a long-dead tribal woman, the researcher is startled to hear a description of a dream she had about people from afar watching her. The researcher shows it to several colleagues, "rewinding" the event twice before continuing. The tribal woman continues that they watched her three times and even gives the correct number of researchers. The researchers are a little freaked out.

* The first half of ''PastwatchTheRedemptionOfChristopherColumbus'' is all about this kind of device. Then they figure out how to do actual time travel...

* ''The Dead Past'' by Creator/IsaacAsimov is centered around such a device.
** In a twist, the ''really'' important aspect turns out to be something that in practice ''isn't'' about looking into the past (or the future, which the device can't do): it can look at any place at any sufficiently recent time... which means there is no privacy, since there are no limitations on how *close* to the present it can look. The government knew about this before (it was their motivation for their draconian rules, the intent being to keep it out of most hands and (per their representative's statements) unused, but once the protagonists invented a cheap and simple way to duplicate the technology and spread it widely...
*** Of course, Asimov failed to notice that his StrawmanHasAPoint: the government's power was based on their monopoly on chronoscopy, they blatantly admitted that they had used it specifically to suppress competition, and all scientific research was strangled by the same bureaucracy as chronoscopy, most likely enforced through the same means. The protagonists did not destroy privacy by [[CantStopTheSignal publishing their findings]], merely the government's illusion of it.

In ''Film/TheInvisibleRay'', Janos Rukh has invented a telescope that can photograph light rays that will show the Earth's past. He uses it to watch a meteorite fall on Africa, thus starting the plot.

* In ''Podcast/KakosIndustries'' Corin Deeth III's grandfather Corin Deeth I uses a Predict-O-Vision device to see glimpses of what his successor is up to, being CrazyPrepared for the day he'd be succeeded as CEO of the company. He's increasingly been sending letters from around the mid 1960s to offer advice, or sometimes just to send an immature joke. Most notably, he's unable to accurately see what [[CreepyChild Belladonica]] is and urges Corin to [[TemptingFate give up on trying to open]] [[BrownNote the contraption]].
