Fever Screening with FLIR Thermal Imaging Cameras

Latest update from FLIR Systems (31/3/20)

Thermal Cameras UK/Stanburys Ltd are here to assist you with any FLIR Thermal Imaging cameras or any information for Elevated Body Temperature (EBT) Monitoring.

The information below will help your decision-making. Please read it thoroughly and watch the videos.

The easiest FLIR EBT monitoring solution is a handheld camera in “Screening mode.” Here is a short demonstration video: https://www.youtube.com/watch?v=GVWZ-70Pkds&feature=youtu.be

Here is another video of the FLIR T540 detecting EBT on a child with mild fever (99.9F / 37.7C as reported by oral thermometer): https://www.youtube.com/watch?v=AHE-iWZLfpg&feature=youtu.be


Researchers have confirmed a correlation between the eye cantus temperature (tear duct area) and core body temperature. Accurate temperature measurement requires multiple pixels focused on a target area. Thermography experts recommend cameras with minimum 320x240 pixel resolution and focusable optics for skin temperature measurements on such small targets.

Repeatable maximum temperature measurement is a function of distance, so EBT screening should be done on individual faces at a constant distance. Higher resolution allows greater stand-off distance, especially considering current CDC “social distancing” guidelines.

Screening Mode is available on *ALL* FLIR T-series and Exx-series handheld cameras.

Pistol Grip Form Factor (handheld or tripod-mounted use)

E75 - 320x240 pixels

E85 - 384x288 pixels

E95 - 464x384 pixels

Tiltable Optical Block Form Factor (better handheld and tripod-mounted ergonomics)

T530 - 320x240 pixels

T540 - 464x348 pixels

T840 - 464x348 pixels (like T540 but with an eyepiece for outdoor use)

T640 - 640x480 pixels

However, all models above are sufficient if used correctly.

LEAD TIMES: (Updated 26/3/20)

Extremely high demand during the ongoing pandemic has consumed all on-the-shelf stock for both FLIR and FLIR’s distribution partners.

SHORTEST: We happen to have material on hand to make a number of T640 cameras with 24 deg lenses. These cameras are made on a separate line so they can be produced much more quickly than the other T-series cameras. This camera exceeds the requirements necessary for EBT, and comes at a higher price point, but it has the shortest lead time. It's a great choice for those who intend to "dual purpose" the camera and use it for industrial or scientific purposes in times of reduced concern for elevated body temperature screening.


FLIR products are not medical devices and cannot diagnose coronavirus infection. When configured correctly, the FLIR products discussed here can identify individuals showing higher than average temperature relative to a sample population. Only a licensed medical professional can determine if a “hot” individual is experiencing an abnormal medical condition.
