Philip K Dick did at least, in A Scanner Darkly https://en.wikipedia.org/wiki/A_Scanner_Darkly

> When performing his work as an undercover agent, Arctor goes by the name "Fred" and wears a "scramble suit" that conceals his identity from other officers. Then he is able to sit in a police facility and observe his housemates through "holo-scanners", audio-visual surveillance devices that are placed throughout the house.

When will we need to start wearing "scramble suits"
