The Sapienza computer scientists say Wi-Fi signals offer superior surveillance potential compared to cameras because they're not affected by light conditions, can penetrate walls and other obstacles, and they're more privacy-preserving than visual images.

[…] The Rome-based researchers who proposed WhoFi claim their technique makes accurate matches on the public NTU-Fi dataset up to 95.5 percent of the time when the deep neural network uses the transformer encoding architecture.

It was very much not even far fetched at that point. 1984 wrote about the same kind of surveillance, and at that time it would have been pretty far fetched. It was published in 1949; the video camera was only 24 years old at that point.
