It’s been almost three weeks now since Downing Street announced that it wanted people to return to work if they could not work from home. Just 24 hours later, the government published a detailed plan which outlined how it would slowly begin to lift social distancing measures so people could once again return to work, schools could reopen and badly hit sectors such as retail and hospitality could slowly begin to welcome back staff and customers.
One of the biggest barriers to getting people back to work, consumers back to local businesses and children back to class is the need to maintain social distancing and be alert for a virus that for many people at least initially, presents no outward symptoms.
So, just how can you safeguard your team, visitors and customers while also opening your office, retail space, leisure space, educational institution or hospitality venue? With thermal imaging cameras.
How do thermal imaging cameras work?
A thermal camera is designed to interpret different levels of infrared light and use that data to determine temperature. Infrared light is invisible to the human eye so it would be impossible for a security guard, a receptionist or similar to observe whether or not someone had an elevated temperature or was running a fever just by a glance alone.
According to NHS guidance, a high temperature is one of the main symptoms of COVID-19. While other symptoms such as a persistent cough are much easier to observe without the use of specialist equipment, it’s impossible to know if someone is entering your building with a fever.
Scanning with a thermal imaging camera detects the different levels of US light emitted to pinpoint when someone’s core body temperature is elevated past normal levels. This could be a warning sign of an individual with coronavirus, given other symptoms can take between two and 10 days to present.
Being able to scan all employees and visitors to your premises as they enter with a thermal imaging camera gives a non-invasive way to identify persons who have a high temperature. This allows for entrance to the building to be denied to that person so that further action, such as the administering of a coronavirus test can then be carried out. That individual can be isolated before they enter into a communal space or come into contact with other customers or staff members, therefore preventing the spread of COVID-19.
Thermal imaging cameras are most effective at protecting your workplace when placed at the entranceway. Smaller businesses and spaces can scan with a handheld device, giving instant notification of temperatures which could be a cause for concern.
Larger spaces can use wall mounted or tripod-mounted cameras to scan persons as they are entered, again allowing for those who may be carrying the virus to be identified and prevented from coming into close contact with others.
