With the increase of new influenza strains around the world
(Swine Flu or Avian Flu) and since the recent SARS scare, the use of
Thermal Imaging Camera systems for human body temperature screening in
public places, for example airports, is becoming more popular and proves
to be very successful in identifying individuals with likely signs of
having a high fever. Already implemented and
used in a number of Japanese airports, for the prevention of SARS, it
was possible for operators to identify individuals that had a body
temperature greater than 38°C, as having a high fever is a typical
symptom of SARS and Influenza.
These systems either portable or tripod mounted with a
video output to an LCD display, gave a clear view of the individual,
identifying the areas of a persons body, mainly the face that had a
higher than normal temperature. With the addition of the Fusion mode, it
was also possible to mix a thermal image with that of a normal video
image, allowing for the identification of the individual.
As to how the officials or agencies respond to the
findings from these checks vary, but in extreme cases it could mean
quarantine for those identified as a high risk.
NEC AVIO currently have three systems available, which
are ideally suited for this type of application, the IS7800, TVS-200EX
or the TH9100SL, featuring a temperature range of 0 - 50°C, 0.1°C
resolution and an accuracy of 1°C. Of course other cameras are available
that feature a greater temperature range of higher accuracy.
These cameras also feature an alarm output that sounds
when a passing persons temperature exceeds the alarm levels entered.
