The global AI-based fever detection camera market size is USD1.28 billion by 2020 and is projected to reach USD 2.19 billion by 2027, exhibiting a CAGR of 8.0% during the forecast period. The worldwide surge in the growth of corona infected people has led to the emergence of advanced artificial intelligence-based fever detection cameras to monitor and detect human body temperature. Vaccine for coronavirus is still in its development stage and hence, the only way to reduce the spread of this pandemic is to isolate the infected person from the crowd. This type of camera is being considered as an efficient and effective device to identify a person with high temperature as fever is one of the symptoms of coronavirus. An individual with high temperature is further screened with virus-specific tests.

Many companies, that are remaining open during the coronavirus pandemic, have introduced temperature screening of their employees, customers and visitors. As an example, Walmart has announced it will be taking thermal temperature checks of every employee. The focus is to identify anyone who may be sick before they come into a warehouse, distribution center or other facility. Fever (pyrexia) is when a human's body temperature goes above the normal range of 36–37 Celsius (or 98–100 Fahrenheit). Triggers for fever include viral, bacterial, and parasitic infections.
