We have to start by saying that thermal imaging cameras are devices that could easily translate heat or thermal energy into visible light. The result leads towards a thermogram, or picture in which you can see all heat signatures around.

Of course, since the technology advanced, the same thing goes for high-end cameras that are highly sophisticated devices that could easily capture images and display them in real-time.

Generally, we can use the images to conduct a diagnosis method by using evaluation software for body temperature.

That is why you should check out this site: https://athena-security.com/coronavirus-detection for more information about thermal imaging cameras used for detecting coronavirus.

As you can see, technology is changing the way we conduct temperature checks, which is essential for areas with heavy transit such as airports, train stations, and other commercial surroundings.

How Do They Work?

We tend to see visible light around us every single day, but that is just a tiny piece of spectrum that surrounds us. Generally, visible light is the small part of the electromagnetic spectrum, while the IR or infrared radiation is much more significant and invisible.

Since all objects tend to reflect, absorb, and transmit energy on various levels, the same thing goes for cold and hot energies all around us. This particular type of camera is perfect for detecting all types of signatures for numerous purposes.

The Common Applications

It entered the scene back in Korean War years with an idea for soldiers to use them on the field for additional clarity. At the same time, firefighters use them to see through smoke, which also allows them to localize fires or hotspots.

Have in mind that law enforcement is also using this particular technology to handle surveillance activities, apprehend and locate suspects, conduct search and rescue operations, and investigate crime scenes.

Besides, numerous maintenance technicians that are operating power lines can locate overheating parts so that they can prevent future issues and failures that may happen.

As soon as thermal insulation becomes problematic in a particular building, construction workers can use these cameras to detect leaks, which is much more efficient than other practices conducted in the past.

Finally, the latest models can detect physiological activities, including fever in human beings, which is a crucial consideration for preventing pandemics.

Features You Should Consider

You should remember that thermal imaging cameras come in a wide range of price tags and features depending on your application. Generally, you can find the ones that come with a lack of features we have mentioned above.

The low-end cameras come with the ability to read the temperature only at a particular spot, such as the fixed center of the display. You can find numerous color palettes, including rainbow, iron, and black/white, among others.

The most common choice for household inspections is an iron palette due to its transparency. On the other hand, the black/white palette is perfect for identifying details on a particular image.

Finally, using a rainbow palette will provide you the best thermal sensitivity so that you can differentiate temperature varieties of surroundings.

Other features include:

• Color Alarm – This particular feature will allow you to get notification based on previous selection and programming. Therefore, the camera will display only things that are either below or above the desired temperature, which is essential for surveillance and other applications.
• Picture-in-Picture – Using this feature will give you the ability to display the color of a particular temperature at one part of the display that will use the standard images in most cases. Therefore, you will have a limited array of temperature readings based on the position of the camera.
• Blending – If you wish to blend within either minimum or maximum temperature that you wish to follow, you will be able to choose the size of the thermal image within the digital one whenever you decide, or something pops up.

Benefits Of Thermal Imaging Cameras

As you can see from everything, we have mentioned above, the standard option for security and surveillance includes 24-hour thermal imaging cameras. Therefore, they are essential components of airports, seaports, borders, and other essential infrastructure.

We decided to present to you the common benefits that come with these cameras:

• Low Light – If you are checking out the building perimeters, you have to handle low-light scenarios and situations that could affect the security of a particular building. Therefore, you will be able to enjoy the clear perspective of everything during both night and day, which is an essential consideration in general.
• Standard Cameras Come With Visual Limitations – Using standard cameras is similar as following our eyes, which means that it will have trouble seeing through visual blocks and obscurants that happen due to invisible reflected light. Since thermal radiation tends to pass through visual barriers, thermal imaging cameras can see much more things than others.
• Reduce Camouflaging Issues – The common problem in security, in general, is the inability of regular cameras to capture and make differences between the similar patterns and colors, which is why they blend. That is a common way of reducing the efficiency of detection, which could ultimately lead to security issues.
• Reduce False Alarms – Thermal imaging is a much more affordable way to protect your business or commercial building; because you will reduce the chances of getting false alarms that are common with standard surveillances that have sensors, among other things. Since the high-end models use advanced analytics software, you will get the high contrast images and videos as a result.
• Increase ROI – Remember that these cameras are not as expensive as you previously thought, especially if you have in mind that you will increase the overall security of your property. Therefore, the overall costs of having CCTV systems compared with thermal imaging cameras are similar. Keep in mind that due to high range capabilities, you will need less of thermal cameras compared with regular ones. At the same time, regular cameras are unable to see during the nights and require additional lightning fixtures that are affecting the overall safety.
