The Best Thermal Imaging Camera Reviews

Spread the love

Have you been shopping around for the best thermal imaging camera? Look no further. In this article, we’ll discuss the top 5 infrared cameras and add a few buying tips just for you. So what exactly are we talking about?

A Thermal imaging camera (TIC) or the infrared camera is a device that functions using infrared radiations to form an image. These cameras mostly operate in a wave range of up to 14000nm. They then convert heat or thermal energy into visible light for analyzing objects within cloggy environments such as smoke and darkness.

They were originally devised for the military to use during firefighting. However, today, their uses have advanced, and they come in several sizes and shapes to allow portability.

How Does a Thermal Imaging Camera work?   

Thermal imaging cameras focus their special lenses to objects which in turn emit infrared light. The infrared detector scans the light and creates a detailed pattern using the different temperatures emitted to form a thermograph. The thermograph is then transformed into electrical impulses which are sent to the signal processing unit where they are translated into data and displayed. The information is shown in the form of color intensities according to the strength of the infrared emission.

What Defines a Good Thermal Imaging Camera?


The quality of the camera is very important. It needs to have excellent sensor resolution as well as other functional features. Even though the budget is equally important, don’t go for a cheap product and compromise the quality.

Sensor resolution

The sensor resolution of an infrared sensor is a significant factor when purchasing a thermal imaging camera. Low resolution can limit the gadgets application. When the field of view is large, with a low resolution, you will have difficulties in viewing the exterior façade of the house. In addition, when examining an electric circuit, a low lens resolution camera and a narrow field of view are appropriate since the object in question is small.

Ease of use

The camera should be easy to use especially for beginners. Most devices come with many additional features which can be confusing to a beginner and this may increase the training cost and period. However, it’s essential that the integrated camera and the laser provide easy targeting to allow quick operations. Finally, the camera should not have very many buttons because they can cause difficulties for people with large hands and they can also cause confusion when working.
