A Quick Guide To Temperature Scanning Systems

14 October 2022 by Hugh Larson

Any business that wants to stay open during a pandemic, like the recent COVID-19 outbreak, needs to have a temperature scanning system in place. But there are still a lot of questions about these systems—how they work, how accurate they are, and more.

This article will answer a few burning questions about temperature scanning systems so you can make an informed decision about whether or not to implement one at your business.

How Does a Temperature Scanning System Work?

A temperature scanning system is an automated kiosk that uses infrared technology to take someone's temperature. The system is made up of a thermal camera and a computer. The thermal camera captures the infrared heat signatures of people as they walk by.

The computer then uses an algorithm to convert the heat signatures into temperatures. The whole process happens in a matter of seconds and is completely contactless.

The system is placed at the entrance of a building, and anyone who wants to enter has to step up to the kiosk and have their temperature scanned. If the person's temperature is within a normal range, the kiosk will print out a pass that they can use to enter the building. If not, the kiosk will print out a fail.

Temperature scanning systems can also be integrated into existing security systems, like turnstiles or access control systems. These types of systems use the same infrared technology, but instead of printing out a pass or fail, they will either grant or deny access to the building, depending on the person's temperature.

How Accurate Are Temperature Scanning Systems?

Temperature scanning systems are very accurate. In fact, they are more accurate than other methods of temperature taking, like oral thermometers, which were previously the gold standard for temperature taking. Studies have shown that thermal cameras can accurately measure temperatures within 0.54 degrees Celsius of the actual temperature.

That said, there are a few factors that can affect the accuracy of a temperature scan, like if the person has just had a hot drink or if they are sweating. Placement is also important—the system needs to be placed in an area with no direct sunlight, which can throw off the readings.

It also needs to be placed in an area where there is a clear line of sight to the person's forehead, as that is where the infrared heat signatures are emitted from.

Overall, temperature scanning systems are very accurate and provide a quick and easy way to take someone's temperature. They are a valuable screening tool that can help prevent the spread of disease.
