As the corona crisis develops, Belgian Avalasia is being flooded with orders for its fever scanner. The camera, combined with heat vision, can measure the body temperature of individuals within large crowds. Originally marketing it as military equipment, the company couldn’t have predicted the sudden demand.

As many companies struggle to continue with operations, some are experiencing unprecedented activity. One such company is Belgium’s Avalasia, which develops and sells ‘fever scanners’. These scanners can be used to measure the body temperature of individuals, in order to identify possible illness within large crowds. In the second week of March, the Menen-based company sold dozens, valued at 25,000 euros apiece. CEO Nico Ramacker: “I used to struggle to convince possible clients that checking their employees for body temperature was necessary. That hesitance has vanished completely.”

They never meant to make a profit out of the crisis, emphasizes Ramacker. “The scanner was already our core business. We’re just trying to fill this sudden need for detecting fever.” Ramacker explains that right now, they’re solely in reactive mode. “We couldn’t have predicted this sudden demand.”

Ramacker first had the idea for the fever scanner during the 2002-2003 SARS epidemic in China. He stayed in Shanghai at the time and experienced the events first-hand. In 2011, Avalasia was founded, at that time serving as a small enterprise active in the security sector. Over the past few years, the company specialized in heat vision cameras, as well as security solutions.

Military equipment

In 2018, Avalasia first attempted to integrate its fever scanner system into regular cameras. This enables security guards to identify heightened body temperature of individuals in a crowd. A possible use is antiterrorism, as nervousness also causes a slight increase in body temperature. After a year-long development phase, Avalasia presented the product at Milipol, an expo for homeland security and safety, in November 2019.

At the Bits&Chips Event 2023 on 12 October 2023, Phillipa Hopcroft from Crocotec and Ivo ter Horst from ASML will kick off with a keynote speech on transforming how lithography machine software is built. Make sure to keep an eye on the website for program updates and save the date!

The scanner itself consists of an IR camera that continuously calibrates with a regular video camera. The hardware is imported from China, whereas the software is developed in house. The heat camera identifies the individuals with heightened body temperature and then points them out on the regular image made by the video camera. The system can also be integrated into existing CCTV solutions. This means people won’t have to stop to be scanned. A large crowd can just pass the camera and a security guard can cherry-pick the outliers.

Crazy times

In 2019, Avalasia realized a turnover of 1.5 million euros. Naturally, the company expects to grow in 2020. “These are crazy times for us.” Most customers, especially in Belgium and the Netherlands, are in the food industry. “It makes sense that they’re more cautious. However, we’ve also received orders from, for example, IT companies.” All these clients want to check their own employees when they come to work. “But outside of the Benelux, the scanners are also used in public areas.”

In November, the focus was still on antiterrorism and security. “Now, all other projects are paused as we try and meet the demand for fever scanners.” At this time, Avalasia’s biggest bottleneck lies in logistics. “We need to get our products up and running at the customers’ locations.”


Avalasia is currently looking into a collaboration with Imec in Leuven, to help improve user experience. Ramacker hopes the corona crisis will increase public awareness of viruses. “That’s something I noticed when I was in China. Their awareness of hygiene and contamination is much larger than ours.” For now, he wants to help face the crisis at hand. “We’ll have to work with what we have.”
