Fever is not only one of the most prominent symptoms of Coronavirus infection but also one of the earliest. An infected person may have elevated temperature without being aware of it or having any other symptoms, therefore temperature screening of people whether they
be shoppers, travelers or employees is vital to secure any space- office, mall or otherwise.
An Infrared Thermometer is a device which measures the temperature of the a person without contact by collecting and measuring the infra red rays emitted by the person. All warm objects radiate heat to the environment in the form of infra-red rays. These thermometers sometimes also have a laser which gives it a gun like appearance. The sole function of the laser is to work as a pointer to indicate which part of the body (Usually forehead or wrist) is being focused on!
Infrared thermometers may be part of thermal cameras which can track multiple people at the same time with or without face recognition or the more ubiquitous laser gun operated by a guard or receptionist. Modern Infrared Thermometers provide reliable and accurate readings of body temperature.
Even one infected person in a closed space has the capacity to infect many other people in the same space. Increasingly infrared thermometers are becoming an indispensable hygiene tool for secure and well maintained offices, malls, cinema halls or even countries where the incoming traveler must not only go through physical and X Ray security but also Infra Red Ray security!
