Bahaa Abdul Hadi points out that corona virus has wreaked havoc on businesses and
other organisations that rely on people working in a physical location. The ability to
reopen and let people back into their buildings has been a very urgent requirement for
many. These groups are looking into the best strategies for returning individuals to
work when home restraining orders and business closure orders starts to withdraw
globally
Health monitoring has become one of the most important elements in the effort to keep
the employee population safe throughout the pandemic and maybe into the future.
While several new apps have been developed to promote self-reporting, many
businesses have found that this is still insufficient to protect their employees’ health and
safety. These companies have started looking for technological solutions to screen
employees as they enter buildings.
Access control, however, is still a crucial requirement for any institutions that need to
guarantee that only authorised people can pass through an entry point. Touchless
access control solutions have very quickly gained popularity in response to the
emerging dangers to health and safety because they reduce the spread of bacteria and
viruses. Face recognition has emerged as the leader among them due to its high level
of accuracy.
Thermal cameras have recently gained much popularity as a biometric access control
method in addition to facial recognition, it can also detect hot spots.
An imaging camera functioning consists of spotting heat coming off the target. When
positioned at an entry point,its facial recognition technology can scan visitors within
minutes to manage access while also recognising people with hot skin. Human
Resources or other authorities are informed of this crucial information by alerting and
notifying capabilities, who can subsequently take the necessary measures to safeguard
the remaining personnel on the job site.
Sensor innovations for thermal cameras
Now a days, thermopiles and microbolometers are the two important types of thermal
sensor technology used everywhere. There are some major distinctions between the
two which have an impact on their capacity to provide the best temperature taking
performance.

2. By sensing an object’s infrared energy, thermal cameras with thermopile and
microbolometer sensors estimate temperature. The temperature will increase in direct
proportion to the amount of infrared radiation being released.
However, thermopile sensors used in thermal cameras result in low-resolution images
with just few thousand pixels. These sensors have drawbacks, including the
requirement that people remain still and the lengthy screening process.
The high-resolution photos from a thermal camera as compared to microbolometer
sensors, have more than 10,000 pixels. This makes thermopile cameras less accurate
at measuring temperature than microbolometer-type cameras. Subjects do not have to
remain still to be measured because microbolometer sensors can gather information
considerably more quickly and accurately from a variety of positions. This makes it
possible to quickly measure people as they pass the camera.
Bahaa Abdul Hadi drafts the below suggestions to improve the output of the thermal
camera:
1. Put the camera in a secure location. There should be no direct sunshine, any
large heat sources nearby, with little wind or air movement possible.
2. Avoid places where windows, metallic objects, or other reflective surfaces cold
reflect light into the camera’s imager.
3. Use a shielding item such as a screen or a tent to cover the camera if it has to
be used outside. For maximum performance, use the gadget in their commended
ambient temperature range.
4. Keep reasonable distances between people passing the camera.
5. Screen each person separately.
6. A person being examined should not have been recently engaged in any activity
that raises body temperature, such as exercising or taking a bath. After such
activities, give the subject a 30 minute of rest.
7. To prevent evaporating heat from reducing temperature, wipe any perspiration or
moisture off the skin region which are getting scanned.

3. 8. For maximum accuracy, ask every person in screening to take off anything that
might be blocking their forehead. Examples are their hat or their hair bands.
9. Ensure that everyone is facing the camera and that the camera captures their
whole face.
10. Perform a further examination using a medical tool on anyone who exhibits an
increased skin temperature.
