How Thermal Camera Detect covid - 19 Virus?

• The Covid-19 pandemic has changed the world
  drastically, with the global economy been pushed
  into one of the worst recessions of recent times.
  According to a certain survey, approximately
  71.31 percent of the businesss people
  experienced reduced cash flows with the
  manufacturing sector being the worst hit. And
  now, only post lockdown optimism has left with
  the respondents.
• As lockdowns ease, businesses hope thermal
  imaging cameras will be key to safe reopening. We
  all know that big-bang changes are no longer the
  way to handle this situation but we also think
  the Government must use this camera technology to
  instill trust in the business community and
  improve ease of doing business. Let us see what
  exactly thermal imaging cameras do?

• Thermal imaging cameras are basically the cameras
  that use infrared technology for detecting
  radiated heat from a body - usually from the
  forehead - and then estimate core body
  temperature.
•  
• Where your normal camera captures the light of
  the object, the thermal detecting cameras capture
  heat emitted by the object.

• However, temperature-based screening, such as
  thermal imaging, isn't that easy nor they detect
  coronavirus. High body temperature is just one of
  the common symptoms of the virus along with
  nausea, headaches, fatigue, and loss of taste or
  smell.
•  
•  "May not be very effective" type but thermal
  cameras have given an opportunity to bolster the
  industrys confidence through targeted policy
  solutions. An overwhelming majority of
  businesspeople (90) believe that the Government
  should focus on implementing thermal cameras
  during the post lockdown period.

•  
• The main benefit of Thermal Imaging Systems is
  that the person who controls the thermal imaging
  system is not required to be physically close to
  the person who is being evaluated.
•  
• Also, the thermal imaging system measures surface
  skin temperature faster than any other
  thermometer that requires a close distance or
  physical contact with the person being evaluated.

• If thermal imaging cameras id a person with a
  high temperature, then health authorities can
  conduct a Covid-19 test. 
•  
• By using this technology through concerted
  efforts, and by reposing faith in domestic
  businesses... will only make India shine again
  after the pandemic period.
