One of the things that can contain the spread of the pandemic, if not eliminate its chances of spreading, is early and timely detection so that transmission can be contained. Screening of elevated body temperatures is the first line of defence after social distancing, to fight its spread. Keeping in mind the nature of the pandemic, the screening must be contactless and from a safe distance.
Fortunately, technology today makes it possible to mass screen individuals for elevated body temperatures without contact, in an efficient, convenient, cost-effective and from a safe distance using thermal cameras.
What is the difference between thermal cameras and IR thermometers?
To understand the difference between a thermal camera and an IR Thermometer it is important to understand a basic principle. Every object or thing, including humans, emit infrared waves - a form of lightwave outside the visible band. This infrared radiation increases with a rise in temperature, because of friction in mechanical items, because of resistance in electrical items, loss of moisture because of evaporation, etc. Both thermal cameras and IR thermometers detect these infra-red radiations and translate it to a temperature reading.
Thermal cameras detect and screen from safe distances
Because of advanced optics and technology, thermal cameras can also determine temperatures from a longer distance compared to an IR thermometer. This helps in maintaining social distancing and avoids transmission of deadly viral diseases such as SARS, Ebola or Covid-19 at close quarters.
Thermal cameras allow for rapid screening of multiple people
An ideal requirement for mass screening in places with high footfalls, or at places where to and from movement of people is frequent (like schools, offices, malls, etc.) is that it should not restrict or impede traffic flow or cause time delays. Thermal cameras allow for rapid screening of more people at a time than an IR thermometer.
Thermal cameras can be deployed for central monitoring with minimal human resources
Depending upon the environment, thermal cameras can be deployed in either unattended positions for central monitoring or with minimal human resources as they have in built display connectivity & alarm systems as against IR thermometers which needs round the clock manpower allocation who are constantly exposed to the transmission of infection as scanning is done from a close distance.
Thermal cameras have data storage and visible camera capabilities for future reference
Thermal cameras have data storage and visible camera capabilities can be used to easily review past records and conveniently provide reference as required for control check points and government scrutiny.
