What Is a Thermal Imaging Camera?
Before we can answer this question, first we have to understand the concept of thermal imaging.
Thermal imaging is a scientific method of measuring an object’s (or objects’) temperature by utilizing wavelengths of infrared lights. This is why thermal imaging is also often called infrared thermography.
Thermal imaging is a non-contact measurement, meaning we don’t need to directly touch the object to measure its heat/temperature. Instead, this method converts the infrared waves into a visual image that shows different colors. These colors represent different temperatures.
A thermal imaging camera is simply a practical implementation of this technology in a fairly small, handheld camera, which is very useful in the case of electrical inspections and diagnosing mechanical systems.
Since the thermal imaging camera is a form of non-contact measurement, it is easy to use and completely safe. You can easily detect a temperature drop or rise and any hot spots in just a few seconds with this handheld camera.
During electrical inspections thermal imaging cameras are used to pinpoint potential failures in equipment, cables, or systems.
This can prevent power loss, damage, or downtime, which can be more expensive particularly in areas where equipment cannot be shut down. This is also true where physical contact with the equipment is not possible (i.e. due to safety concerns, or in the event that contact might alter its temperature and skew the measurement.)
So, a thermal imaging camera provides two key benefits:
- Visual way to locate hot or cold spots. Thermal imaging technology allows a very fast measurement of temperature without requiring one to shut down the equipment/system.
- Safe measurements from a safe distance. Thermal imaging cameras provide the ability to measure temperature without contacting the object from a safe distance. This is important not only to avoid touching hot equipment, but also when dynamic measurement is needed (object is in motion), or it is unsafe to acquire contact-type measurements.
What to Look for in a Thermal Imaging Camera?
There are four key factors to consider when choosing between different thermal imaging cameras:
Resolution
There are two kinds of resolutions involved in a thermal imaging camera: the resolution of the monitor screen, and the resolution of the detector/sensor. No matter how high the screen resolution is, the image can only be as good as the resolution of the sensor.
The higher the sensor’s resolution, the sharper, clearer, and more accurate a single dot will be on the display monitor, and this will allow us to measure smaller objects from a greater distance.
So, if your operational environment involves the need of measuring equipment from further, you will need a higher resolution in your thermal imaging camera.
Pixel size, measured typically in micrometers (microns) is also important in determining the level of detail produced by the camera. The smaller pixel sizes, the better and the more detail you’ll see.
To summarize, look for the following resolution features in your next thermal imaging camera purchase:
- high pixel detector resolution, and
- high display resolution, and
- low pixel size.
Temperature Range
Another important consideration is the temperature range of the thermal imaging camera. Imaging cameras that can measure wider and/or higher temperature range will use more expensive sensors, which will translate into a more expensive device.
The best thermal imaging cameras can measure a very wide temperature range from -20°C to 400°C, and there are also imaging cameras that can measure up to 1,200°C.
So, when choosing between different thermal imaging cameras, first check whether the measurement range requirement of your day-to-day application.
Sensitivity
Sensitivity in thermal imaging cameras refers to how small the sensor/detector can detect differences in temperature.
Devices with higher thermal sensitivities can detect smaller temperature differences, so it can produce an image with greater accuracy. The camera will detect a broader range of temperature differences, producing more colors on the screen.
Sensitivity is measured in mK (milliKelvins), the lower the mK the better and more expensive the camera will be.
Data storage and export
Most thermal imaging cameras can store the measurement data in its built-in memory and removable SD cards, so we can export the stored data to a computer for backup and data analysis/reporting.
Premium thermal imaging cameras might also offer functionalities like Wi-Fi/Bluetooth data transfer to allow direct data transfer to smartphones, tablets, or computers for more versatile analysis and reporting.
Thermal Imaging Camera vs Infrared Camera
It’s important to note that while thermal imaging cameras do involve infrared measurements in how they operate, they are not infrared cameras.
The main difference between the two is how the detection takes place:
- A thermal imaging camera measures the absolute temperature of the object by measuring the mid-infrared radiation emitted by the measured object. Due to this measurement method, a thermal imaging camera can work in complete darkness since it doesn’t depend on light, and it can work without an infrared beam.
- An infrared camera (or called active infrared/IR camera) uses short wavelength infrared light (the beam) to illuminate an object/area of interest. It will then detect the reflection of this beam and generate an image. The beam can be mid or long wavelength of infrared. Active infrared cameras are affected by smoke, light interference, dust, etc. while thermal imaging cameras aren’t.
How Accurate are Thermal Imaging Cameras?
Typical thermal imaging cameras can produce an accuracy of +/-2 °C or +/-4°F. This level of accuracy is, in most cases, enough in electrical inspections, but might not be enough in, for example, measuring human body temperatures when a 2°C difference can be very significant (i.e. 36°C is considered healthy while 38°C is not.)
Can I Use My Smartphone as a Thermal Imaging Camera?
This is a great question, and the answer is YES! With thermal imaging cameras becoming smaller and lighter, it would only make sense that the technology would enter the smartphone market.
There are actually two ways we can use our smartphone as a thermal imaging camera:
- Getting an actual thermal imaging smartphone with a built-in thermal imaging camera. There are products like Caterpillar CAT Thermal Imaging Rugged Smartphone available in the market.
2. Getting a thermal imaging phone adapter, which is a detachable thermal imaging detector/camera that we can connect to our smartphone via thunderbolt/micro USB/USB-C.
The latter option is relatively popular nowadays, as you can get a pretty decent thermal imaging camera while using your phone’s screen as a display for under $500. There are two notable companies making thermal imaging adapters for smartphones: FLIR and Seek Thermal.
FLIR offers three products in this category:
#1. FLIR ONE Gen 3 (the entry-level model)

While you won’t get the same level of details you’d get with a standalone thermal imaging camera, especially the high-quality ones, these thermal imaging adapters can be a cost-effective, pretty decent option.
However, they are not as durable as the standalone cameras, and will rely on your phone’s battery power.
So, if you are planning to regularly use a thermal imaging camera (i.e. if you do electrical inspection daily or if you are a home inspector), then you should get a dedicated device instead.
How Far Can I Measure with a Thermal Imaging Camera?
The spot-size ratio tells us how far we can be from a measurement object and still get an accurate temperature measurement with the thermal imaging camera.
The smaller the pixel size of the detector, the more pixels can be latched onto the target measurement, which will give more details in the produced thermal mage.
On the other hand, the higher the resolution of the camera, the more opportunity to get more pixels on the target. It’s important to note that digital zoom of the camera won’t improve measurement accuracy.
So, in measuring the effective distance of a thermal imaging camera, we should consider three factors: the camera’s resolution, the horizontal field of view of the camera (FOV), and pixel size.
We can calculate the spot/size ratio with the following formula:
Spot/size ratio= IFOV (Instantaneous Field of View) in inches : distance of measurement
While we can measure IFOV with:
IFOV (in mrad) = (FOV / number of horizontal pixels) x [ (3.14/180) x (1000) ]
Then we should convert the IFOV from mrad to inches with the following formula:
IFOV (inches) = IFOV (mrad) / 1000 x measurement distance in inches
For example, if your camera’s resolution is 160 × 120 pixels (160 horizontal pixels) with horizontal FOV of 24-degree, and you are going to measure an object from 10 feet away (120 inches)
Then, first, we are going to measure the IFOV in mrad with the above formula:
(24 / 160) x [ (3.14/180) x (1000) ] = 2.616 mrad.
Then we are going to calculate the IFOV in inches:
(2.616 / 1000) x 120 = 0.31392 inches
Then we get the spot/size ratio = 0.31392” : 120”
We can then use cross-multiplication to know how far we can accurately measure a 1” spot:
0.31392 : 120” = 1” : X
120” x 1” = 0.31392 x X
then solving for, X = 120” / 0.31392”
therefore, X = 382.26 inches or 31.855 feet
So, with this thermal imaging camera in the example, we can accurately measure the temperature of a 1” spot from 31.855 feet away.
Some manufacturers list the camera’s theoretical spot size ratio, and you can use the above formulas to calculate the effective distance. All manufacturers should list their FOV and resolution, so you should be able to make the calculations yourself.
Why Thermal Imaging Cameras are Important for Electrical Inspections?
Here are some common applications of thermal imaging cameras during electrical inspections:
- Thermal imaging cameras allow us to check for temperature spikes associated with high electrical resistance before the circuit becomes hot enough to cause an explosion and/or outage. We can easily check thermal patterns caused by poor surface contact and multi-phase imbalances causing overloads.
- Detect problems caused by switch contacts and connectors by detecting abnormal heat through contact. In these cases, the point of heating may be very small, and a thermal imaging camera is necessary to detect the heat point.
- Easily check abnormal temperature differences between different controllers and wires, which can be a sign of an overloaded circuit.
- Find equipment/appliances that need replacement easily. In a huge system with hundreds of pieces of equipment, finding a device that is likely to fail can be difficult, but a thermal imaging camera can easily detect the absence of a heat signature.
