The simple answer is yes, thermal imaging is effective for pre-screening temperatures, but only if we understand its limitations. In understanding those limitations, it can be deployed to greatest effect, bringing the greatest benefits to employee confidence and reduction in infection risks.
According to the FDA (the US Food and Drug Administration), thermal imaging systems can provide fast skin surface temperature readings with accuracy while maintaining social distancing rules. The caveat here is that temperature-based screening is not a way of definitively saying someone has Covid-19, given that a fever is not always present and a full diagnosis can only be attained with a test. However, with the right setup, this temperature-based screening becomes a safer way to screen for possible symptoms, and one of the few methods of pre-screening before that person enters the premises.
Thermal cameras need to be deployed in a location where the ambient temperatures are not raised and placed where they will have the best chance of reading temperature at forehead height. Following implementation guidelines from your supplier and manufacturer is the key to making sure that your thermal imaging solution is situated correctly and will provide the most accurate and consistent readings.
Before you make any decisions on choosing to implement the technology, we recommend being very clear with how it can and can’t be used.
Thermal screening cameras cannot definitely detect coronavirus or fevers. They can, however:
👉Provide fast and accurate within ±0.5°C skin temperature readings
👉Provide a non-contact screening method
👉Automatically alert if a temperature is elevated
👉Give a history of all screening conducted, providing a simple audit trail
👉Depending on the solution, screen many people at once, or individuals at speed
