The Need of Thermal Cameras for Corona Virus Screening

Let us first understand what actually Thermal cameras are and for what use they are meant for. The thermal cameras detect the temperature by recognizing different levels of infrared light. This light is invisible to the naked eye but can be felt as heat if the intensity is high enough. These cameras can be used to detect elevated body temperature. If the temperature of the skin especially the corner of the eye and forehead is above the average temperature then the individual may be prescribed for additional screening tests.
