According to Thermoteknix:
MIRICLE FevIR Scan thermal imaging and temperature measurement system from Thermoteknix is easily installed, operated and re-located with the very minimum of setup time and operator training.
On screen visible and audible alerts provide instant notification of high temperature alarms.
On-screen alerts identify one or more individuals in a large crowd situation, aiding rapid detection and maintaining passenger flow.
Operating at 50Hz (9Hz models available for export licence requiring countries), MIRICLE 110K ensures that a high rate of human transit is monitored effectively without slowing queues in busy areas.
They add this most welcome note: Caution: Human skin temperature varies with environmental and physiological factors. Raised skin temperatures can occur in the absence of fever and vice versa

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 www.TempSensor.net.
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 www.temperatures.com 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: www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=51236 and webstore.ansi.org RecordDetail.aspx?sku=IEC+80601-2-59+Ed.+1.0+b%3a2008 respectively.
