Top Smartphones with Thermal Imaging Cameras (2023)

In recent years, smartphones have evolved into powerful tools that not only keep us connected but also help us capture and share our daily experiences. With advancements in technology, the capabilities of smartphone camera keep being expanded and extended. The arrival of smartphones with thermal imaging cameras is another step forward in this evolution.

Thermal cameras are a rarity on regular smartphones, for the simple reason that the average person has no need of them, Zero. But there is a category of devices that they come in useful – rugged or outdoors phones. These are phones built tough for outdoors professionals and enthusiasts e.g. search and rescue teams, security personnel, engineers, hunters, hikers, campers, and the like. This category of users finds thermal cameras useful.

Top Smartphones with Thermal Imaging Cameras

What are thermal cameras and what are they used for?

What do thermal cameras do? They allow users to see and capture objects that are visually difficult to see – whether in daylight or in the dark. They work by capturing the heat signature of objects they are pointed at. Think of infrared vision as seen in movies, and you have a good picture of the situation. Smartphones with thermal imaging cameras can be used to find missing people, animals, or objects in the dark or through smoke, can be used to detect camouflaged persons, animals or things, and can be used to detect heat leakages in industrial work areas.

How do Thermal Imaging Cameras work?

Regular cameras have lenses and sensors that work with light; thermal cameras have lenses and sensors that work with heat. They capture heat energy, process it, and render it as an image. Brightness or darkness does not matter at all here. All that a thermal camera works with is heat, and all humans, animals, and objects emit heat to varying degrees.

As lighting doesn’t matter, smartphones with thermal imaging cameras are better at detecting hidden or camouflaged objects better than the regular phone camera. Regular cameras are incapable of this, and thermal cameras are also incapable of doing what regular cameras do – processing light.

Are Thermal Imaging Cameras limited to night use alone?

Not at all. They can be used in daytime, for example, to see through fog or smoke, or to locate camouflaged persons, animals or objects in broad daylight as much as in the dark. This is because, unlike your regular camera, thermal cameras do not capture light; instead, they capture heat.

Do thermal imaging mobile apps work?

Thermal imaging apps work only if the phone has a thermal camera built in or added as a clip-on. Without a thermal sensor and lens, a thermal imaging app is useless.

Do you need a smartphone with a thermal imaging camera?

If you are not involved in the outdoors as a profession or a hobby, or do not have industrial use cases for it, you do not need a smartphone with a thermal imaging camera. For example, I love the outdoors and fairly often have one adventure or the other. Having a thermal imaging camera in my smartphone will come in handy for me every now and then. As already mentioned, for most people, there is little use, if any, for a thermal imaging camera.

Can you add a thermal imaging camera to your regular smartphone?

Yes, you can buy an attachable thermal camera that you can clip to your iPhone or Android phone, so you can use this extra functionality.

The Best Smartphones with Thermal Imaging Cameras

While there are not many of them in the market, the field of smartphones with thermal imaging cameras is growing and quite a number of them are in the market already. Here is my curated list of the best of them.
