What Is an FLIR Camera?

What is a FLIR Camera? - Energy Electronics LLC (1)

A FLIR camera is a type of camera that uses forward-looking infrared thermal imaging technology. They were primarily developed for military use. Today, these types of infrared cameras can be used for a wide range of activities, from monitoring traffic to executing quality control for electrical installations. The reason why FLIR cameras are valuable in numerous industries is because they feature diagnostic technology, which is used to assess, visualize, and solve thermal issues.

What FLIR cameras essentially do is detect thermal energy and produce light that’s projected onto a display as an image. This whole process is called thermography. The final result is an IR diagnosis report that’s interpreted by professionals who then evaluate the situation and find the best possible solution to the problem.

FLIR cameras are also heavily used in maintenance in order to verify how dependable various mechanical and electrical systems are. That being said, these types of cameras are not only used to analyze locations, but objects as well. This is possible as energy can be emitted, reflected, and conveyed by virtually all objects, just at different frequencies.

With the help of these devices, workers are able to detect a potential problem and solve it before it becomes a real issue, saving a lot of time, money, and effort.

What Does FLIR Stand For?

What is a FLIR Camera? - Energy Electronics LLC (2)

FLIR stands for “Forward-Looking Infrared.” Previously, all types of thermal cameras were referred to as FLIR cameras. However, this description is no longer accurate since it technically refers to a FLIR branded camera. Interestingly enough, the term FLIR was first used in the 1960s, when thermal imaging technology was in the developmental phase.

The term “forward-looking” is accented because there are different types of thermal imaging systems. It refers to fixed forward-looking infrared technology, as opposed to so-called “sideways tracking” thermal imaging systems.

How to you Pronounce FLIR?

The term “FLIR” is pronounced like most acronyms, by simply saying each letter one at a time. In this case, the correct way to pronounce “FLIR” is “F,” “L,” “I,” and “R.”

Why Are FLIR cameras so Expensive?

What is a FLIR Camera? - Energy Electronics LLC (3)

For starters, FLIR cameras are far more advanced than regular cameras, which capture light that’s visible to the naked eye. FLIR cameras, on the other hand, pick up on invisible thermal energy, which is basically heat. The light is then presented in various colors, which indicate the differences in temperature.

FLIR cameras are so useful as they create images based on thermal energy without having to scan anything with a standard motion sensor. It goes without saying that these cameras are so expensive because they employ state-of-the-art infrared technology. What’s more, they use various infrared detection sensors to perceive any form of thermal energy emitted by an object.

Another reason why FLIR cameras are so expensive is that they can be used in a wide range of fields and industries. As mentioned before, FLIR cameras were first utilized by the military. They can be a valuable asset in surveillance, tracking, and searching. Today, they’re employed by construction and warehouse workers, pilots, firefighters, drivers, electricians, engineers, photographers, etc.

For anyone interested in purchasing an FLIR camera, the good news is that their prices have been falling in recent years. This is due to the growing popularity of portable and fixed infrared technology, which is based on microelectromechanical system applications.

FLIR Multimeter vs. Phone

What is a FLIR Camera? - Energy Electronics LLC (4)

There are different ways to use FLIR cameras. For those who want a more compact device that’s portable and lightweight, you have two options to choose from: FLIR multimeters and FLIR phones.

Multimeters are created to measure electrical current, voltage, and resistance. More hi-tech digital models can measure temperature and thermal radiation as well. To use this device, all you have to do is point it towards the area you want to scan, and press the IGM (Infrared Guided Measurement) button. With a FLIR multimeter, you can use non-contact voltage measurement. These digital devices are very easy to use, facilitating the quick and efficient completion of work tasks.

In comparison, FLIR phones are much more versatile as they offer a larger number of specifications. Popular rugged phones, like the CAT phones series, not only have built-in FLIR cameras but many other features, including break-proof technology, an extra-long battery life, Wi-Fi and Bluetooth connectivity, ample memory space, and much more.

If you’re not sure which device you need, a FLIR multimeter or a phone with a FLIR camera, your decision should be based on your requirements at work. While FLIR multimeters have a lot of handy functions, phones with FLIR cameras give you much more diversity and useful features.

Can FLIR Cameras See Through Walls?

What is a FLIR Camera? - Energy Electronics LLC (5)

Technically speaking, FLIR cameras don’t have the ability to “see” anything. On the contrary, they detect thermal energy that’s emitted by people or objects and turn them into various colors based on the temperature differences. While FLIR cameras can perceive and measure the energy emitted and reflected by objects, can they do so through walls?

Even though this scenario has been reenacted in countless movies, it is highly unlikely. FLIR cameras can’t see through walls because they’re too thick, and in most cases, insulated. Therefore, any thermal energy behind the walls would be blocked. However, if the FLIR camera is directed towards the wall, it would be able to scan thermal heat from the wall itself, not from anything that might be behind it.

Moreover, if there is a heat source on the other side, which is powerful enough to change the wall’s thermal energy, a FLIR camera should be able to detect this shift in temperature.

This highlights just how useful FLIR cameras can be in these situations. They can pick up on any temperature variances within the wall and uncover issues that might not be revealed otherwise. That’s why building maintenance and construction workers can greatly benefit from FLIR cameras. These neat devices can detect a variety of issues, like leaks, missing insulation, malfunctioning wiring, and similar.

Does FLIR Work in Fog and Rain?

What is a FLIR Camera? - Energy Electronics LLC (7)

When it comes to fog and rain, thermal imaging technology performs less effectively. The droplets, which allow less thermal radiation to escape, make it more of a challenge for FLIR cameras to detect heat. That being said, FLIR cameras are still able to penetrate fog and rain much better than a regular visible light camera or the human eye.

FLIR cameras can also penetrate smoke, which is why they’re used by firefighters. The hotter something becomes, the more thermal energy it will emit. Even though a reduced amount of light will be detected due to smoke and soot particles, a FLIR camera would still be able to pick up on it. This helps firefighters navigate rooms full of smoke when they can’t see anything.

Thermal imaging technology works even in complete darkness. Have you ever watched a National Geographic documentary where the photographers use infrared cameras to spot animal activity at night? This is because FLIR cameras don’t need daylight, or any other type of light, to capture thermal radiation. In other words, thermal imaging technology isn’t affected by darkness at all.
