Thermal imaging cameras are currently being installed in office buildings, hospitals, shopping malls, schools and airports as a means of detecting people with fever-like symptoms. Given that these cameras are not necessarily designed to operate as medical devices, there are questions about their suitability in the context of the current pandemic. This note provides an overview of the use of thermal imaging empowered with artificial intelligence (AI) capabilities, its suitability in the context of the current pandemic and the core technical limitations of this technology. The main legal responses and ethical concerns related to the use of AI in the context of thermal imaging at entry points to identify and triage people who may have elevated temperatures are also examined.
