How We Decided
Like most other kinds of cameras, the most important aspect to consider with thermal imaging cameras is how accurately it gives you a picture of your subject. In this case, that includes the subject’s temperature, whether hot or cold. When it comes to this accuracy, there are a few different features we rated. For starters, we only included cameras on our list if they provided a thermal sensor of at least 60×60 pixels. We rated options higher if their thermal resolution was higher. However, we also considered each camera’s thermal sensitivity. At a bare minimum, we only included options with a 2°C thermal sensitivity, but preferred options with more accurate sensitivities.
Next, we rated the thermal cameras based on their overall design and build quality. It’s highly likely that you’ll be using your camera in situations where you might drop it, get it wet, or use it in extreme temperatures. We only included options on our list that can last in rugged scenarios. The cameras we included above often have tough, rubberized exteriors. However, we rated options higher if they included additional durability features. This includes options with features like IP water and dust resistance ratings, thermal sensor covers, and carrying cases.
Finally, we scored each camera based on its general usability. At a minimum, we only included thermal cameras above if they didn’t require any kind of specialized training to use. The thermal imager you buy should be easy to use for most users in any kind of situation. If you get bogged down by complicated controls or hard-to-press buttons during a crucial moment of your inspection, you might miss what you’re looking for.
Best Thermal Cameras Buyer’s Guide
The Most Important Features to Consider
- Thermal Resolution
The camera’s thermal resolution is also known as its temperature sensitivity. This refers to the camera’s ability to separately discern two different objects that are emitting similar levels of heat. The higher the resolution, the better the camera will be able to display the differences in two objects with similar temperatures. Having a high thermal resolution is important for specialized fields like firefighters who need to find warm bodies in an already hot environment or inspectors determining friction between two moving parts. Most commonly you’ll find that thermal cameras can detect variations within one to two degrees Celsius. More specialized models will be able to detect variations within around 0.045 degrees Celsius.
- Temperature Range
The temperature range you need from your thermal imaging camera depends mostly upon how you’re using it. For the most part, a range between -4 and 220 degrees Celsius is perfectly fine. However, there are also cameras with temperature ranges skewed toward a colder range or a hotter range. There are also cameras with extended ranges on both ends for more versatility.
- Image Resolution
Like with standard cameras, the image resolution on your thermal camera is an important consideration to make. Purchasing a thermal camera with a high image resolution will allow you to determine exactly where heat is being generated in more complex areas. Purchasing a thermal camera with a low image resolution can make this entire process much more difficult.
- Screen Size
A large screen can help you see more details in the thermal images, but the size you need is largely dependent on your own personal preferences. Purchasing a camera with a large display also enables you to easier operate the camera, especially if it’s a touchscreen display. Most thermal cameras offer displays that are around 2.5 to 3.5 inches big.
It’s likely that you’ll be using your thermal imaging camera in plenty of tight spaces, which is why portability is so important. Choose an option that’s portable and lightweight enough to carry around with ease. Many options also include handles for better handling, but these handles can sometimes get in the way. If this is a potential problem for you, consider a camera that features a removable handle or one that doesn’t feature a handle at all.
Depending on how you plan to use the thermal camera, you may want to consider its durability. Of course, there’s a certain level of durability you should expect from any expensive purchase and most of these cameras are able to take a bump or two without a problem. There are also models that are designed to withstand drops from tall heights or extreme temperatures without failing.
- Additional Features
Thermal imaging cameras often include a variety of additional, application-specific features to consider. These won’t be useful for every user but may be helpful to your individual needs. Features like different thermal palettes and measurement modes can help you more accurately measure hot and cold spots. You can also purchase additional lenses for different views. Don’t forget things like onboard storage or the ability to store images and videos on an SD card. You may even get advanced features like picture in picture, a wide field of view, or even Wi-Fi connectivity. Take some time to consider what additional features you need and find a camera that offers those same features.
Thermal Cameras FAQs
Who makes the best thermal imaging cameras?
FLIR and Seek are among the top thermal imaging camera manufacturers in today’s market. However, there are also a variety of other top-notch companies from which to choose. If you purchase a camera from companies like Fluke, PerfectPrime, and Urpro, you can rest assured you’re getting a solid product.
How accurate is a thermal camera?
For the most part, thermal cameras are very accurate and will work well for most applications. When it comes to numbers, you can expect an average of ±2°C. However, under the right conditions, IR cameras may experience a variance as little as 1°C. Of course, you may not be able to achieve such accuracy depending on the environment in which you’re using your thermal camera, so it’s good to be aware of the standard variance.
How much is a thermal imaging camera?
Most thermal imaging cameras range in price from around $350 to $450. However, there are still excellent options available both above and below this range. With thermal cameras, the phrase “you get what you pay for” is especially true. We recommend sticking in this dollar range but have included a budget option above that is still a good product.
Why are thermal cameras so expensive?
Thermal imaging cameras are typically more expensive than other options simply because they use advanced technology components. The components are highly unique and situation-specific to thermal imaging, which makes them higher overall than others.
