FLIR’s Infrared Products for Fever Detection

From the FLIR website comes the following story that was last updated 16-mar-2009 (only 1 month and 17 days ago).
Thermal Imaging To Detect Body Temperature As A Screening Technique to Limit the Spread of Infectious Disease

It starts off with the statement:

The Threat to the Global Public Health & Economy

Swine flu (H1N1), SARS, Asian Bird flu: these are the names of infectious disease pandemics that have occurred just over the past few years. While they differ in symptoms and severity, they are deadly. Their repeated occurrences highlight the inherent frailty of public health worldwide.

It then goes on to highlight the equipment and their features offered by FLIR for this application with sections entitled:

“Adaptive Algorithm” Helps Identify Persons with Fever
First Step: Limiting the Spread of Infectious Disease
Infrared Cameras for Fever Detection:
Features & Benefits
Temperature Measurement Accuracy
Color Alarming
Threshold Fusion

fever-detection-mounting2The thermal imagers FLIR recommends for this application are their fixed-mount Model A320 (shown here and the portable or handheld Model T360. Both have a “color alarming” feature.

The portable T360 can also be seen in a YouTube video “Camera Used To ‘See’ Fever” just published. Just Click here

The following links to their product brochure downloads (in PDF Format) for these two models are:
A320 for Fever Detection
T360 for Fever Detection

FLIR also notes that they manage the worlds largest infrared camera training organization, the Infrared Training Center or ITC. Expert guidance and training as well as post-sale technical support is available for deployments of FLIR thermal imagers for elevated body temperature fever detection. They offer training and post-sale technical and customer support worldwide.

In addition FLIR has Rental & Test Programs for Health Agencies. Call or write them for details.

Why such a series?

This series of stories highlights the suppliers of Temperature measurement devices intended and specially designed for screening people for elevated body temperature, a likely indicator of fever and possible an infection, such as SARS, Avian Flu, Swine Flu, Dengue and others.

We do this for several reasons:

1. Most people are unskilled in selection and use of Infrared Thermal Imagers and thermometers. Consequently there are often serious mistakes made in both choosing and using such devices. We feel it is important to use our knowledge of them to try to save us from those who rush to judgment on technical matters without adequate input and thought. We are highlighting equipment suppliers who make devices tailored for this use as evidenced by product details on their web pages. (This is not an endorsement of those suppliers but rather an information resource to help cull out those who have some experience and products intended for this use.)

2. Please be aware there are now some international standards for these devices, their performance, and introductory standardized practices for their use. You can get the best help in selecting and using them, we believe. from experts at your National Measurement Institute (NMI) who specialize in the infrared field. There is a list of all the NMIs in the world at the website of the International Bureau of Weights & Measures (Le Bureau international des Poids et Mesures – BIPM) and a selected list on

3. Some vendors are more careful and experienced than others and we recommend that you check the experts at more than one of them before making any decisions plus run your views past the NMI experts before finalizing them.

4. Although the use of these devices doesn’t directly detect infection or all who are infected, it has been demonstrated that their careful use and selection during the SARS crisis of 2003 can help screen for and locate some who have the illness. The individuals then get more rapid treatment and are quarantined to reduce their possible effect on others. (See the SARS pages on for some details, reference stories and article links)

5. Yes, there were undoubtedly false negative as well as false positives in earlier uses. There will always likely be some of both. However, misuse, mostly though improvised practices and hasty, ill considered equipment choices, will increase the probability of more false negatives.

6. An effort to finalize ISO Standards for equipment performance and use will go a long way to improving the situation. Until a viable set of standards, developed by world experts are in use, we shall see continued mis-specification and misapplication of equipment and subsequent squandering of resources, in our opinion.

Note In late 2008, IEC published the standard: IEC 80601-2-59 Ed. 1.0 “Medical electrical equipment – Part 2-59: Particular requirements for the basic safety and essential performance of screening thermographs for human febrile temperature screening” . It provides many performance and calibration requirements for devices used in this application.

In March 2009, the ISO standard, ISO/TR 13154:2009 “Medical electrical equipment — Deployment, implementation and operational guidelines for identifying febrile humans using a screening thermograph”, was published. It bears directly on this use, and while not perfect, does represent a major milestone completed since SPRING Singapore began their effort to create workable standards in 2003.

The standards may be purchased and downloaded online at: and RecordDetail.aspx?sku=IEC+80601-2-59+Ed.+1.0+b%3a2008 respectively.
