Thermal Screening Technology in Health Care


The year 2020 has been challenging for everyone around the world with the COVID-19 pandemic sweeping the globe and affecting the health of the citizens dramatically. As part of the effort to curb the contagion of coronavirus and maintain economic opportunities, the government and health care sectors of countries around the world are utilizing thermal temperature scanners, as another weapon in their armoury to fight the COVID virus.


The purpose of using this technology is to detect potential COVID-19 by measuring the temperature of people as they go about their business in commercial spaces. From hairdressers to grocery stores, a temperature scanner identifies anyone who has an above-normal reading which may be a sign of COVID. Scanning of visitors and employees, allows businesses to filter out individuals in these commercial places who may be suffering from the virus. Health experts rely on these body temperature scanners to identify heightened thermal temperature scanners, as another weapon in their armoury to fight the COVID virus temperatures that may be due to fever, one of the common symptoms of coronavirus disease.


How Do Infrared Temperature Scanners Work?

The Infrared temperature scanners are usually contactless devices that scan the facial temperatures of up to 40 people in one go. The temperature reading is accurate within 0.3 degrees Celsius. Health authorities around the world have agreed that these devices when used correctly are as accurate as oral or rectal thermometers. The Infrared thermometers typically read the infrared energy emitted by human bodies and record the temperature. These scanning devices offer a helping hand in recording temperatures and notifying personnel immediately of abnormal temperatures. To the person being scanned, they are just a click away from knowing if they have a high temperature. Let’s face it, we have all become much more aware of our body temperature as one of the signs for COVID during the last 12 months.

Body Temperature Measuring Units

In fact, do you find yourself gauging your forehead temperature with the back of your hand more often? Well, you're not alone; with the upsurge of Covid-19, high temperature is a recognized sign of falling ill. Normal human body temperature is 98.6˚ F (37˚ C) and under normal circumstances 100˚ F (37˚ C) is not considered as fever. But anything beyond 100.4˚ F (38°C) is a cause for concern.


Types of Imaging Cameras

A thermal imaging camera helps in detecting the body temperature of people. The system comprises a camera, an NVR bracket, a temperature calibrating device, and all the necessary brackets for installation. Accounting for the density of population these thermal devices can be categorized into:


High traffic density |

These solutions are designed to add value to places witnessing a large influx of people like healthcare centers, supermarkets, offices, events, etc. Temperature screenings at these places allow quick checks and invoking immediate action in the event of a feverish state.


Medium traffic density |

Scanning devices like Infrared Temperature Guns or other portable temperature screening solutions are generally included
