The 11 Best Thermal Imaging Cameras: Reviews and Buying Guide

Be it for crime-solving or building a safe home for people to live in, new gadgets with exotic features always make everyone's life much more comfortable.

On that note, inventors around the world come up with ingenious product ideas, and such a product is the thermal imaging camera.

In this guide, you will find the 11 best thermal imaging cameras.

As an architect, detective, or a mechanic, you must have hoped for a product that could scan right through the walls. There is good news for you because this handy camera will allow you to make your wildest dreams as a professional come true.

What is a Thermal Imaging Camera and How it Works?

A thermal imaging camera is a unique device that produces image unseen to naked eyes. It can detect abnormalities inside any solid object by using infrared rays and hot and cold signals. In simple terms, it uses temperature parameters to develop an obscure image.

The image may not be like the highly pixelated color cameras that we use.However, the images produced have vibrant shades to them that indicate the temperature state of the object being captured.

This whole process reads both analog and digital signals to capture the thermal condition of the object and convert it into electrical signals for producing a vivid image.

Aside from the complicated process of actually creating the image, the manual work is quite easy. The picture is taken as an ordinary camera while the circuits do the complicated work.

There are two types of thermal imaging camera, uncooled and cryogenically cooled. As the name suggests, the latter camera is more sophisticated and provides better imaging, whereas the uncooled camera gets the work done cost-effectively.

And the main difference between the two types of camera is that the uncooled camera works under average room temperature, and the cryogenically devised camera has special chemicals that keep the temperature inside the camera below 0 degrees.  

The 11 Best Thermal Imaging Cameras

A camera itself is a sophisticated device that can capture beautiful moments. Taking that theory into mind, several thermal imaging products in the market can help you as an architect, detective, or a mechanic.

You can even use such a device in forensic lab work. However, for an accurate reading, you need the best thermal camera.

Things to Know Before Choosing a Thermal Camera

A camera that deals with infrared rays and temperature differences are very sensitive and technical. Without the proper knowledge, the person can easily lose track of what to buy. However, the best thermal imaging camera in the market has some qualities the user should know about.

  • Display

The monitor of this kind of camera is the most important. If the screen is wide and clear, the captured image becomes more vivid. The display quality will also let the picture be more vibrant. Most thermal cameras have a display of 3 inches or more. Some brands manufacture LCDs for better imaging.

Depending on the need of the user, they can choose LCDs or regular displays. If the work is professional, then the LCD monitor will be more useful.

  • Camera Body

The thermal imaging devices come in all shapes and sizes. And the most common portable thermal imaging looks like a gun and also has triggers like a gun. These are easy to use as they have navigation buttons on it. There are also some cameras that have a wider display.

If the user wants an accessory thermal camera, then they can look for mini thermal imagers which transform the smartphone into a temperature sensor. The body is made of strong material that can contain the sensitive circuit. These cameras need to be maintained for optimum performance.

  • Image Enhancement

There are various color palette options and overlay systems that enhance the image even after the high-quality lens has done its work. There are up to 7 palettes of color to choose from, which even include a negative mode along with the black and white mode. According to the work requirements, the user should purchase the device.

Some device also offers MSX enhancement, which increases the clarity of the image to the point where you can see the entirety of the object. Professionals usually need such clarity.

  • Lens

This is the factor which decides how far and how much focus needs to be used while clicking the image. Most of the models are compatible with more than 220 X 340 thermal sensors and can easily take the image without the need to focus.

However, if the object is isolated from the background, then the lens can capture an image with more clarity. This will help in better analysis of the situation and will help the user to decide faster.

  • Resolution

The best thermal imaging camera for home inspection always has a high resolution. This depends on the picture taken per frame, and the faster the frame counts, the better the resolution. Resolution can be identified with pixels, and it will be stated in the manual. Higher pixel number will indicate better resolution.

  • Temperature Limit

A good imager will be able to detect temperature between a wide range. Commonly, these imagers can detect temperature abnormalities above zero. Some devices can detect below the standard temperature too. In short, the wider the range, the better will be the outcome.

  • Battery

These cameras can be both rechargeable or battery oriented. If the camera is battery operated, it will be a lithium-ion battery.

The voltage on such devices is 3 volts. Some cameras also have a storage facility and USB cables. If the user wants to connect the imager without any cable, they can also purchase Wi-Fi compatible camera.

Frequently Asked Questions

Below we have some of the most commonly asked queries regarding thermal imaging cameras:

What is the difference between an infrared camera and a thermal camera?

Thermal cameras use radiation frequency emitted from a place of the infrared region while an infrared camera uses light frequency to form an image.

Do thermal cameras use infrared?

Thermal cameras use infrared rays to develop the image by turning the analog signal into digital units.
