Thermal Scanner Advantages and Disadvantages for Businesses

Because businesses are now reopening amid the COVID-19 pandemic, ensuring the safety of employees has become a top priority. One important tool for achieving this is the thermal scanner.

Let’s explore what thermal scanners are, how they work, the benefits of thermal scanners, and how they can help businesses maintain a safe and healthy workplace.

What are Thermal Scanners?

Thermal scanners are devices that use infrared technology to detect body temperature from a distance. They are non-invasive and can quickly and accurately measure the temperature of an individual without physical contact. Temperature screening has become a critical practice in the prevention of the spread of COVID-19.

How Do Thermal Scanners Work?

Thermal scanners use infrared sensors to measure heat emitted by the human body. They provide a visual representation of body temperature by displaying the heat map of any object they detect. When a thermal scanner is used to measure the temperature of an individual, it reads the heat map of the individual’s face and provides information on their body temperature in real time.

Now that we know what thermal scanners are and how they operate, let’s discuss the many thermal scanner advantages and disadvantages.

Advantages of Thermal Camera Scanners


These electronic instruments are designed to detect body temperature without physical contact and can hence scan someone without putting the user at risk of contamination. This way, thermal scanners become an essential aspect of pandemic management, especially in screening key areas for individuals who present with a high temperature. Their potential to curb the spread of deadly viruses is unparalleled, making them a more hygienic and reliable screening method.

Fast and Efficient

These high-tech devices are designed to scan large groups of people quickly and accurately, delivering precise temperature readings in a matter of seconds. Thanks to their rapid response times and remarkable accuracy, thermal scanners have become an increasingly popular screening option for those looking to keep their workspaces, employees, and communities safe from the spread of infectious diseases.


Thermal scanners have emerged as one of the most cost-effective medical equipment in recent times. Not only do they provide quick and accurate temperature readings, but the cost of acquiring one is relatively low compared to other medical technologies. With the raging pandemic taking a toll on economies globally, the affordability factor of thermal scanners is a significant advantage.

Detection of Asymptomatic Cases

High body temperatures are often a warning sign of illness, and thermal scanners can quickly identify these temperature spikes in both symptomatic and asymptomatic individuals. By identifying individuals with high temperatures, thermal scanners can help prevent the spread of infections like COVID-19.

High Accuracy

These state-of-the-art devices can accurately read body temperature, helping healthcare providers to identify and monitor individuals who may be carrying a contagious illness. Thermal scanners are also incredibly efficient, making them a key tool in preventing the spread of outbreaks. With their unparalleled accuracy and speed, it’s no wonder that they have become an essential part of any public space, from airports to office buildings.

Although thermal imaging scanners come with a lot of benefits, they aren’t without their limitations.

Disadvantages of Thermal Camera Scanners

Inaccurate Readings

In today’s world, thermal scanners have become an essential tool to accurately measure our body temperature and detect any signs of fever. However, as much as we rely on these devices, they are not always 100% accurate. External factors like weather conditions, exposure to radiation or heat sources, and even the distance from the device may affect the readings.

False Positives

It’s important to note that these scanners may generate false readings if an individual is not positioned correctly or is wearing glasses. As a result, it is crucial to have individuals positioned correctly and avoid any obstructive eyewear to ensure the most accurate readings.

Incubated Cases

These devices can only measure body temperature and cannot detect other flu-like symptoms such as cough, fatigue, or loss of smell and taste. This means that individuals with these symptoms but without a fever may go undetected and potentially spread the virus further. Additionally, it is crucial to bear in mind that certain individuals can contract an illness and act as carriers without manifesting any symptoms. This can prove exceedingly challenging, as it renders the thermal scanner useless in terms of diagnosis.

Limited Range

Thermal scanners have a limited range. This means that to get an accurate reading of someone’s body temperature, they need to stand still in front of the scanner for a few seconds. It may seem obvious, but it’s worth reminding that movement can affect the temperature readings and provide inaccurate results.

Passive Solution

While thermal scanners may detect elevated body temperatures, they cannot replace active measures such as wearing protective masks and other preventive protocols. Thermal scanners are just an additional tool in the fight against the pandemic, and they should be used in conjunction with other preventive measures.

Despite these disadvantages, thermal camera scanners provide businesses with invaluable features to protect employees in the long-term.

Thermal scanners are a useful tool in combating the spread of contagious diseases. With their cost-effectiveness, high accuracy, and ability to detect even asymptomatic cases, these devices can be used to create safer environments where people can feel comfortable interacting with each other. However, it is important to note that thermal scanners cannot replace active measures such as wearing masks and that false positives may occur if an individual is not positioned correctly or is wearing glasses.

Thermal scanners should also be used in combination with other preventive protocols for the best results. Ultimately, thermal scanners prove to be an invaluable tool in our fight against the pandemic.
