This site was created to help you find the best thermal imaging camera for your budget!

What Is A Thermal Imaging Camera?

Thermal imaging cameras were originally developed for the military in the Korean war and since been adapted to a variety of other commercial and military uses. Thermal imaging cameras today are commonly used to detect temperatures behind walls or other solid objects; as well as checking breaker boxes ensuring circuits are not overloaded. They are also used to detect missing insulation, water leaks and HVAC leaks.

From a commercial standpoint they are commonly used to check the operating temperature of machines and electronics to detect possible issues and/or malfunctions. Being able to “see” behind walls as well as detecting large temperature spikes can help stop thousands and in some cases hundreds of thousands of dollars of damage to expensive equipment and homes. Home owners, Inspectors, electricians, contractors, and auto mechanics are just a few of the people who can make use of thermal imaging cameras.

What Are Some Applications Of Thermal Imaging Cameras?

  • Thermal Cameras for Leak Detection:

We all know how devastating humidity and moisture can be to your home. Thousands and thousands of houses are ruined each year because of undetected moisture damage that is unknown until it is too late. Mold is dangerous and can spread quickly if left undetected. So how can a thermal imaging camera be helpful detecting leaks and moisture causing mold?

A spot in your home that contains water or moisture is cooler than​ the area around it. A high quality thermal camera can easily detect it so you can ​identify the problem and start fixing it quickly. Most professionals use it to spot insulation problems as well.

Built in software can easily generate reports that you can send to homeowners or landlords for review. View a complete list of thermal cameras suitable for leak detection.

  • Thermal Imaging Cameras for  Home Inspections:

As a home owner and do-it yourselfer you have gone ahead and switched out some of the light fixtures in your new home as well added a few extra switches to your wall outlet and to save money you have done it all yourself.

What you may not know is if the house was wired to the correct standard when it was built. If you are pulling too much power from one outlet it can cause a tremendous amount of heat that you may not notice when you flip the switch. Prolonged excess heat can damage your wall and potentially cause a fire. With a thermal imaging camera, you can simply point it at the wall and see if there are any heat spikes due to the additional wiring.

As a contractor or building inspector you may be called in to diagnose why the buildings AC or heating bill is so high – with a high grade Thermal imaging camera you can detect if there is missing insulation broken areas of duct work or other energy efficiency issues.

You will also be able to inspect electrical boxes and circuits to ensure the wiring is correct and the circuits are not overloaded. Without a thermal imaging camera you would literally have to start crawling through the duct work or roof and try to visually diagnose what the issue was which would not only be more difficult but also take a tremendous amount of time.

  • Thermal Imaging Cameras for Fire Service:

Fire fighters face dangers every day. The only way to protect themselves is to have proper equipment and gear. We all have seen expensive flame resistant suits and equipment, but they also have another tool in their hands – a powerful rugged thermal imaging camera that helps them cut through the smoke and haze quickly identifying unconscious people.

They can also use the thermal camera to detect burned out breaker boxes in electrical fires. Having another sense of what’s around you can save lives and help them avoid dangerous situations. Thermal imaging cameras specially designed for fire service are rugged, waterproof and have built in view filters.  These thermal cameras should also be NIST certified; more on that below.

What Is NIST And Why It Matters?

What is NIST and what does it have to do with thermal cameras? NIST stands for National Institute of Standards and Technology and is non-regulatory agency of the US Department of Commerce established in 1901.

This agency is dedicated to advancing standards and technology around measurement science. Again, you are probably asking why do I care; well if you are using or will be using a thermal imaging camera in commercial applications or as a firefighter you very well may need a thermal camera that is NIST certified.

Thermal cameras that have been NIST certified cost more but are essentially guaranteed to produce the most accurate data and information. FLIR offers their As Received As Returned calibration certification ensuring that you get the most accurate thermal images.

This can be essential if you are a first responder using a thermal imaging camera to  locate people who may be trapped in a burning building or other emergency situation where visibility is very limited.

If you are monitoring multimillion dollar manufacturing facility or electrical equipment with very tight tolerances it can be essential that all the data being collected is as accurate as possible to ensure there are no breakdowns or damage to the equipment from operating temperatures that exceed the norm.

If you are just going to be using your thermal camera around the house and for small non commercial home inspections then you probably do not need a NIST certified thermal camera and can save a few dollars on your purchase.

Final Thoughts:

With so many different thermal imaging cameras out there it can be difficult to find the right camera however at the end of the day ​keeping these three factors in mind can help you narrow down the cameras to choose from.

  • What is your budget?
  • What are you going to use the camera for?
  • How often are you going to use the camera?

Knowing how much you can and want to spend is the most important step. Once you are realistic about what you can afford it’s time to narrow down the camera’s in that price range.

Next, you want to think about what are you going to use the camera for: if you are only going to use the camera to look for unsealed windows or HVAC issues in your house you probably do not need a very expensive camera with lots of advanced features a cheap thermal camera can handle these job. Here is it important to be realistic and truthful with yourself and what you will use the camera for.

Finally, how often are you going to use the camera? If you are only going to use the camera a few times a year in a nonprofessional setting it probably doesn’t not make sense to buy an expensive thermal camera.
