Best Thermal Imaging Camera Reviews

We have thoroughly tested and reviewed the best thermal imagers on the market. Here are the top 5 products we selected.

We have made a list of best thermal imaging cameras available on the market at the moment. These products have almost everything one can look for in thermal cameras. Infrared cameras allow you to capture important pieces of information that are invisible to the naked eye. With standard cameras, you’re able to capture only the visible part of the electromagnetic spectrum. However, infrared cameras use IR-sensitive sensors to determine and detect the temperature of the object and represent it visually.

The first thing you need to pay attention to when you’re buying a thermal camera is the image quality. An important factor of every camera is the resolution.

The principle is quite simple, the higher the resolution is – you will get a more detailed image.

Criteria We Used to Evaluate Infrared Cameras


Several factors determine the quality of a thermal camera. You may find it odd that the difference in price is significant, even if we said they’re all similar. The price difference is solely affected by the additional features like Wi-Fi, touchscreen, autofocus, and more.

If you’re not looking for these auxiliary features, feel free to buy a product without them, it’s not always about the price, sometimes cheaper products are the same as the expensive ones, but without some additional features.

The things we tested and compared:

1

IMAGE QUALITY

Image quality is one of the most important factors that determine the overall quality of the product. The crucial parameter for an excellent quality of the picture is the resolution. As we said, the bigger the resolution is - the better the quality. If you’re accustomed to modern smartphone cameras which can produce images up to 12 megapixels, we have some bad news for you. The best thermal cameras don’t exceed 0.08 megapixels. In fact, the standard resolution of thermal cameras is around 0.014 megapixels. There are cameras on the market with lower resolutions, but they’re not intended for commercial and business use.

2

THERMAL SENSITIVITY AND PRECISION

Thermal Precision refers to the product’s ability to capture accurate and distinctive thermal data. The sensitivity relates to the product’s ability to differentiate differences in temperature and represent them visually. Top-quality cameras nowadays detect differences of about 0.05degrees Celsius, or even less. Although increased sensitivity is recommended, even low-quality cameras offer sensitivity of at least 0.15 degrees Celsius. As much as you need to be familiar with this specification, it’s quite similar to every camera on the market, making it pretty insignificant.

Temperature range of the product has been taken into consideration as well. The temperature range tells us the temperature limits within which the product can accurately record. The vast majority of these cameras offer ranges from -20 degrees Celsius up to 250 degrees Celsius. Some high-end commercial cameras work reliably up to 1200 degrees Celsius. If you don’t work with temperatures over 250 degrees Celsius, you shouldn’t have a problem finding the suiting camera for yourself.

Everything you record with your thermal camera emits a level of black body infrared radiation, regardless of temperature. That’s why we also test and compare emissivity.

THE ADDITIONAL FEATURES

Many manufacturers offer additional features such as a touchscreen, Wi-Fi, voice annotations, and more. These extra features significantly affect the price of the product.

Wi-Fi is a great auxiliary component for people who use their cameras for business purposes. Instead of going back to the office and e-mailing the project to your co-workers, you can now easily upload the images directly from your phone.

There are other practical features like laser pointers which can help you target specific areas you want to record. Voice annotation capabilities let you record audio notes on the fly. The design and battery life are quite similar among all thermal camera models, except with expensive two-hand models.

Choosing The Best Thermographic Camera


You need to have several factors on your mind when you’re choosing the optimal camera for yourself. First of all, you need to check the image quality. The image quality directly depends on the resolution. The higher the resolution, the better the quality.

Depending on your particular application, a careful choice is required, because you need to be sure that the camera provides the necessary features you seek. After you’ve established the parameters, it’s time to think about the price. This step is up to you, fine-tune your budget accordingly, and you shouldn’t have any issues.

Remember, the price is not the only thing that determines the quality in this case. Many additional features like Wi-Fi, touchscreen, and auto-focus can boost the price. If you don’t need any of these functions, opt for a cheaper camera.

1. Ease of use

Many modern thermal cameras rely on menu-driven functions and soft-keys. While some offer simple navigation with no more than three keys, other can be quite complicated for use. Even though three buttons seem simple enough, this means the user must take multiple steps and go through multiple menus to reach some of the basic functions.

It’s up to you if you’re familiar with modern technology and with a basic concept of how things work – you shouldn’t have any issues. Oh the other hand, if you struggle to keep up with the modern stuff, consider buying a simpler thermal camera or consult your seller and seek some advice.

2. Durability

Durability is one of the largest factors because you’re going to use your camera in harsh conditions. Impact resistance is crucial because some of the measurements will be taken in unavailable and awkward places, so you can expect this product will be dropped quite often.
