All You Need to Know About Thermal Cameras for Screening Fever

We are all aware of the unprecedented situation the world is facing nowadays with COVID-19 and the severity of the virus across the globe.. Most of the countries across the world have been forced to go into a state of lockdown, these precautionary measures have been taken by the respective governments to stop the extent of virus spread. Everyone is protected in their houses and in their private lives  minimising the risk of catching the virus but what happens when business begin to reopen?  How can we protect our employees and visitors to our premises, will  people be willing to risk their health for their jobs? That is when employers and business owners need to come up with solutions that can effectively assist to reduce risks to employees. One effective solution is thermal cameras for fever detection to assist with detection of personal with raised body temperature.

One of the most common symptom expressed by people affected by COVID-19 is fever or raised body temperature. Taking contact temperature can provide accuracy in detection which is a tad impractical for high-traffic solutions such as people entering an office building. That is when thermal cameras comes into its own, fever screening camera technology can provide a valuable tool to your organization’s safety, health, and productivity. Implementing these solutions is not only a need during this pandemic but any other disease outbreaks that cause raised body temperatures as one of the symptoms.

You can use these thermal cameras for discreet, efficient, and effective operation by identifying individuals that need further screening with virus-specific tests. These cameras are used to assist in the reduction of infection rates through early detection.

Why Security technology?

As stated previously one of the symptoms of COVID-19 is fever or raised body temperature . Fever detection camera system and temperature-sensing security technologies can help detect individuals with raised body temperatures when entering your premises When places like airports, resorts, offices, trains, depots, and hospitals use this technology, they are most likely to spot individuals with a fever. The systems notify security personnel who are expected to take initiatives to them for further screening.

There are many scientists out there who believe that advances in surveillance technology play a fundamental role in restricting COVID-19’s spread. Thermal imaging and Artificial Intelligence are going to play a dominant part in our future.

Different approaches to feature extraction

If you wish to get the most accurate readings, thermal cameras rely on sampling the eye canthus’s temperature. The latter term is used to refer to the corner of the eye closest to the nose bridge. This is considered to be the best facial location for measuring the core body temperature. The technologists generally use two possible approaches for identifying the eye canthus.

  • Thermal only- This approach helps to identify the eye canthus directly from an IR image and measure the temperature.
  • Optical and Thermal- This approach works by detecting facial features, including the eye canthus, using a visual image. This enables to transport the coordinates to the corresponding IR image and measure the temperature.

If we talk about the thermal-only approach, we must collect more data to train a robust deep learning model on IR images fully. So, for creating a POC or a proof of concept in the shortest time possible, choosing the latter approach is the best option. This is a perfect, more cost-effective solution. 

Why Infrared Temperature Screening?

When offices, companies or independent employers use thermal cameras for fever detection, they are accustomed to seeing a plethora of benefits:

  • It helps in protecting the public health by screening for fevers caused by contagious illnesses.
  • It allows security officers to scan large numbers of people as they walk by.
  • Alerts concerned authorities when it detects individuals with raised temperatures.
  • Displays and detects critical temperature elevations in real-time.

Innovative Fever-Screening Technology

Thermal cameras provide a visual map of skin temperatures in real-time and can detect minute temperature differences. If your organization uses infrared cameras, these include color images and temperature scans, and signals when body temperatures exceed set temperature thresholds. And once the organizations are informed of this, it is the responsibility of the security personnel to determine whether to refer the identified individual to the healthcare system.

Artificial intelligence, Corona Detection & Containment Systems, and may more modern technologies integrate into existing security systems through an API (Application Programming Interface) platform. The latter enables professional security installers to install and integrate these advanced technologies into existing security systems.

Using this technology to Screens

It is not long ago that COVID-19 was declared a pandemic by the World Health Organisation. The state and the country officials responded by limiting large gatherings, imposing travel restrictions, and closing non-essential businesses, and educational institutions.  Fever detection camera system can be a viable step to limit the spread of the virus. The screening for COVID-19 must be as meticulous as it can get. Here are the enlisted steps for the detection of the virus. 

Step 1: These thermal detection systems tend to remotely monitor the individuals as they pass screening checkpoints at entrances for hotels, resorts, hospitals, airports.

Step 2: The monitoring station observe colour variations on a screen, they can even receive automatic alarms whenever an individual exhibits an elevation in the body temperature.

Step 3: The monitoring personnel  are responsible for directing persons with raised body temperatures to a separate location for health practitioners screening. 

Wrapping it Up

Though these technologies are not designed to prevent COVID-19 infections, they are excellent at early detection. They can help in reducing the spread of viruses to a great extent. Thermal cameras for fever detection provide a non-invasive and effective way to test passing crowds for the pandemic. Incorporating this technology in your organizations can help you safeguard employees and vistors health as they give an early indication that an individual might be suffering from this infection.
