Smartphone Thermal Camera Body Temperature Measurement Tested (FLIR / Seek)

By: Rob Kilpatrick, Published on Apr 10, 2020

Thermal cameras have exploded in popularity due to coronavirus, but can portable smartphone thermal cameras be used for temperature screening?

IPVM Image

IPVM bought and tested the FLIR One Pro and Seek CompactPRO, looking at these key questions:

  • Can they accurately measure body temperature compared to a typical thermometer?
  • How do measurements change due to sunlight exposure, exercise, and other factors?
  • How simple are the mobile apps to use?
