The Metropolitan Police is to test live facial recognition in Westminster as part of an ongoing trial of the controversial technology.
A deployment of the surveillance software will take place on Monday 17 and Tuesday 18 December in and around Soho, Piccadilly Circus and Leicester Square.
It will be used “overtly” with a uniformed presence and information leaflets available to the public, the Met said.
All faces on the database used during the deployment are people wanted by police and the courts.
Members of the public could decline to be scanned, the Met said.
