With COVID19, requirement for thermal camera seems to be exploding world wide, rightly so.
Automated Body Temperature Measurement by Thermal Camera should been mainstream for long time now. Elevated Body Temperature is one of the most visible symptoms for many diseases. Fever is a symptom not only for COVID19, but also for common flu, infection apart from so many others.
But using just Thermal Camera may not be suitable for usage, specially where the requirement automatic fever detection while entering a building or a factory. Because thermal camera images can not be used for face recognition. So, most Thermal Camera Body Temperature measurement system comes with both thermal camera and visual camera.
This Thermal Camera Body Temperature systems can detect elevated body temperature from multiple people at the same time. It can also recognise the faces of detected person which helps identifying people with fever automatically. It saves crucial time for identifying a person with high body temperature, also it can help spread of infection.
Pyrometers with Visual camera can also be used similar way to detect temperature of one person at a time. Such products tend to be less expensive as well as help social distancing, which seems to be one of the key factors preventing spread of COVID19. Most probably, this could be the most efficient solution for many small and medium enterprises. Its fast, its accurate and it can be integrated with existing attendance system.
Worldwide, it looks like governments will enforce Body Temperature Detection using Thermal Camera or any other IR sensor for factories, commercial building, malls,conference rooms, hotels etc. Thermal Camera industry will get the much needed push to grow. It will also become mainstream, I think, from being exclusive products for industries and military.
With growing demand, its prices will also come down making it more affordable. So, I can see, some eco-system will develop around thermal camera soon.
