Dahua and Hikvision Patent Applications For Manipulating Fever Screening

By Conor Healy, Published Dec 20, 2021, 09:07am EST (Info+)

Hikvision and Dahua have filed patent applications for methods of algorithmically manipulating fever camera readings, contra to IEC/ISO standards. This aligns with the findings of IPVM's peer-reviewed scientific study that their devices used some form of "compensating algorithm" to systematically manipulate temperatures.

Inside this note, we examine the China-filed patent applications and how this shows direct evidence from the companies themselves that temperature readings were being manipulated.

Both companies declined to comment.
