Thermal imaging has been used for front line defence in infection control in use since the SARS outbreak in 2004 to rapidly screen and detect people with signs of elevated body temperature. There are three main technologies – FLIR imagers, Spot IR and Thermal Imaging Cameras.
Thermal Imaging Cameras have two key advantages over the other technologies.
Thermal cameras are discrete, efficient and effective tools to help slow or stop the spread of viruses.
Government deployments demand the highest levels of security and for this reason we have aligned with Mobotix from Germany over several cheaper Asian brands. Mobotix is a company with proven history in government applications both globally and here in NZ.
For the human body the detection points for body temperature is near the inner corner of the eye so careful consideration must be given to proximity, line-of-sight and travelling trajectory for accurate readings.
With accuracy of 0.5 degrees, control of the thermal environment is important in order to reduce false positives, locations indoors will give better results than those outside. Camera location at choke points such as doorways and corridors will yield the best results.
Regular calibration with a black body source is important to maintain reading accuracy, this needs to be taken into account when considering maintenance procedures.
