Best Thermal Imaging Camera Buying Guide

What to Look for in a Good Infrared Camera

If you’ve never bought a thermal imaging camera before, it’s easy to be overwhelmed by the technical jargon. Here’s a simple guide to what you should look for when purchasing.


The resolution of the infrared camera indicates how crisp and clear the results of the image will be. Images that are not so clear cannot show subtle details and it is more challenging to find precisely where the warmer regions are. However, higher resolution cameras are more expensive. A cheaper thermal imaging camera will have a lower resolution, so it is essential to balance your need for detailed images with your budget. Thermal imaging cameras do not have much higher resolution than computer screens. Typically, you will see a value of about 160 × 120 which is 19,200 pixels. Check that you are looking for the detector’s costs and not for the LED screen on the device as it may be different. There is little to pay for high-resolution screens when the detector resolution is low.

Ease of use

Ideally, you want a device that can be set up in seconds and handled using one hand. You don’t want to spend hours putting it together. A simple trigger powers many thermal imaging cameras and you do not need to focus on them.

Range of temperature detection

The more temperature variations you are likely to adopt, the better the complete range. There is a wide range of more expensive cameras so it’s best to get the best for your budget. If subtle temperature differences are essential to you, then you need a device that maintains a high heat sensitivity. A good value would be around 30 10 C (100 mK) around ≤0.10 C, which is enough for most automotive applications.

Image display

You must have a clear view of the image so that you can analyze what is going on. Many thermal imaging cameras come with built-in LED screens that can give you a clear idea of the image. Some cameras may overlay a standard light image with a thermal image to provide you with more detail.

Exporting images

Sometimes you need to save the image for later viewing or sharing with others. To do this, you need an infrared camera to keep the painting to an SD card and many devices come with about 4GB SD card. You may be able to transfer images to other devices, such as laptops, via a USB cable. Some of the more expensive thermographic cameras have a WiFi connection. You can share pictures via smartphone apps.

Smartphone compatibility

If you like the idea of a Thermal compact camera that will use the screen on your smartphone, there are a few cameras available that will slot into your phone and provide a decent image. These may be cheaper than single cameras but the resolution may not be so high. You can easily share images via the smartphone app and the device is straightforward to carry around.

Image frequency

The picture frequency indicates how often the image is refreshed, which can be important when the engine is running and the temperature distribution changes. Most thermal cameras have a frequency of nine Hz which is nine cycles per second.


In order to survive in a workshop, the camera needs to be durable and robust. It needs to have a hard case to prevent it from being dropped or thrown in a tool box!

Why You Should Use an Infrared Camera

Vehicle diagnostics have changed dramatically over the past few decades. Some motor enthusiasts may remember the days when you could tell how your car smelled or what happened to your vehicle. Nowadays, electronic devices control everything from how much fuel is delivered to your car engine. It’s hard to ‘see’ what’s going on in your vehicle, but you can now get a clearer insight into what could go wrong thanks to thermal imaging cameras. A thermal imaging camera lets you work from a visual image, making the diagnosis faster and more accurate. Here are some flaws that your thermal imaging camera can detect.

  • Excess current draw
  • Plugged catalytic converter
  • Current draw when the ignition is turned off
  • Stuck EGR valve
  • Identifying a misfiring cylinder (exhaust manifold)
  • Faulty seat heaters
  • Identifying dead battery cells
  • Broken wires on window defoggers
  • Mass airflow sensor problems
  • Spot a lousy idler bearing
  • Identify a slipping drive belt.
  • Highlight a dragging brake caliper
  • Find issues with the radiator or heater cores (cold spots)
  • Identify uneven braking
  • Find a clogged A/C condenser or evaporator.
  • Spot leaking hot engine oil

A thermal imaging camera is most commonly used in engine bogies, brake systems, and heating and cooling systems in autonomous diagnostics. However, they are also instrumental in solving problems, including insulation and electrical and plumbing. Problems with domestic and commercial heating and air conditioning systems can also be quickly identified using this device.

Best Thermal Imaging Camera FAQ:

Q: What is a Thermal Imaging Camera?

Cameras are used to capture images. Ordinary cameras capture an image using light that people can detect. However, our eyes can only see a thin band of light, referred to as visible light. Visible light is a type of electromagnetic radiation that travels through space as a wave. All kinds of radiation found in the spectrum of locks that have different wavelengths, including radio waves and microwaves. Infrared radiation also found in the electromagnetic spectrum, and thermal imaging cameras use this type of radiation to create an image. The amount of infrared radiation that an object emits is related to its temperature, so it is like a temperature map of an image.

Q: How does a thermal image camera work?

All objects emit infrared radiation. We can’t see it but we can feel it so if you put your hand in front of the flame or heater, you can feel the heat on your own skin. Colder objects emit infrared radiation but you cannot feel it.

Half the energy emitted by the sun is a combination of ultraviolet and infrared radiation and therefore, sunlight can make your skin feel warm.

Heated objects block high levels of infrared radiation. Therefore, if you have a device that can measure the level of infrared radiation, it will let you know how hot things have not come near you.

This is a heat imaging camera. It detects this radiation and converts it into an image using the shadows of light visible on different screens.

Thermal imaging cameras have many small devices called microbolometers and one for each pixel. Each microbolometer captures infrared radiation and converts its pixels into a color that matches the level of radiation.

For example, very high temperatures emit large amounts of radiation and the microbolometer makes it transforms it into a bright yellow/orange color. Most heat cameras have a low resolution that is rarely higher than around 640 × 480.

Q: What temperature range can these cameras detect?

The temperature range is given in the specifications or in the user manual for each camera. This is the temperature range that the camera can detect. Examples are common – more money, more sophisticated devices consuming 760 degrees F to 13 degrees F +. On the other hand, cheap devices on your smartphone have a narrow range of temperature detection, such as +14 এ F to +302 F.
