What is a Thermal Imaging Camera?

Thermal Imaging Cameras are used to see temperature spikes behind walls or other solid objects to detect overloaded breaker boxes, missing insulation, and water leaks as well as many other things. 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 should I be looking for choosing a thermal camera?

  • Detector Resolution (60 x 60 and up to 640 x 480). As a rule, buy the highest resolution thermal camera you can afford.
  • Built in light camera for capturing thermal images. Ability to convert to JPEG type of images and email to client.
  • Accuracy detection of +/- 2%
  • Wide thermal range - the greater the better!
  • Laser pointer for easy navigation
  • Ability to combine thermal image with visible light photo - Image Fusion (available on some high-end cameras)
  • Apps that are compatible with your smart phone or tablet
  • Extended warranty.

Still trying to figure out what thermal imaging camera is best for you or looking to learn more about them and what features may be important to you? Below you will find some of the more common features that buyers look for in thermal cameras. Hopefully this information adds to your knowledge and helps you in your selection of the perfect thermal imaging camera for your needs. Our comparison chart also allows you to easily see the difference between all the cameras that we have currently reviewed.

Thermal Camera Resolution: how important is it and what resolution should you get?

Detector resolution is the most important factor indicating quality of thermal imaging cameras. The higher the resolution, the more precise and accurate measurements of small targets are going to be. High resolution detectors are going to provide thermal image details that cannot be seeing on low resolution cameras.

Keep in mind, thermal camera displays might have more pixels than camera detector, but your actual thermal image is always limited by the thermal detector resolution. You should think of it as up-scaling on your 4K TV. Your TV might have 4K resolution, but if the source (let’s say DVD player) is only 480P, you are only seeing an upscaled image.

What temperature range do I need my camera to be able to detect?

For home use and simply do it yourself types a range of 14 to 300F is more than adequate for almost all scenarios as this will allow you to spot unsealed windows, potential water leaks, and Heat/AC issues.

For professional use in factories or inspections you will need a higher range such as -40 to +600F as this will allow you to spot check heat spots on active machinery that may operate normally at higher temperatures that 300F.

How much money should I spend on a thermal imaging camera?

Like many things that depends upon what you are going to use if for and how accurate you need it to be. If you are a small home or condo owner and simply want to have a thermal imaging camera for checking on heat leaks making sure that there are no water leaks etc. then spending a couple hundred dollars at most will probably be good. One of the Android or iPhone thermal imaging cameras could be great fit as it uses your phone for the display and to save pictures. The iPhone thermal imaging camera is available on Amazon where you can also read customer reviews. Check our article on Flir One vs Seek to get a detailed comparison between these two popular thermal cameras.

If you have a larger home and know you will need to be doing many repairs and checking on old heating/AC systems or a tradesman that has a need for a thermal imaging camera from time to time then it may make sense to spend up to $1,000 for a semi-professional grade camera that is more accurate and will allow you to zoom in on pictures and identify potential problem spots quicker and easier.

Finally, if your profession depends upon daily use of the thermal imaging camera (commercial electrician, inspector, HAVC technician, or commercial property manager) then it may make sense to spend over $10,000 depending on how accurate your reports need to be and the liability associated with an incorrect reading/report.

Many people also fall into the trap of buying the cheapest camera (or other item) for what they need and they realize very quickly that while it may have “all” the features that they needed it may not work as well as other more costly models or may take them longer to complete a project because the camera malfunctions from time to time, processes slower or perhaps the reporting software is not adequate for what is needed.

Should I Buy A Thermal Imaging Camera That is WiFi Enabled?

A common question is whether your camera needs to have WiFi capability; the short answer is probably not unless you are using the camera daily as part of your business home owners and occasional users probably do not need WiFi capability. While it is nice to have this does drive up the price of the camera significantly and unless you are using it every day for professional use it is likely that you will not get the return on the your investment. You should be aware though that if you are using one of the iphone or Android adapters you will be able to to use WiFi so we would suggest checking these out if you want WiFi capability but will not be using the camera day in and day out.

Should I buy a thermal imaging camera that attaches to my iPhone or android device?

Over the last few years that has been some fairly good thermal imaging attachments and one that have been created for iPhones and Android devices. While at first glance you may think that these cannot be high quality or have any worthwhile features however that is not the case. The Seek Thermal Compact Devices is highly rated and have over 900 individual reviews on Amazon.

While these are not suitable for professional use or for homeowners needing advanced features for a first time buyer or someone who only needs to make use of the camera occasionally this could be a great buy especially considering its sub couple hundred dollar price point.

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. 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 in 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 grad Thermal imaging camera you can detect if there is missing insulation broken areas of duct work or other energy efficiency issues. Without a thermal imaging camera you would literally have to each start crawling through the duct work or roof and try to visually diagnose what the issue was which would not only be extremely more difficult but also take a tremendous amount of time.

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 identifying these three factors can help you narrow down the cameras to choose from.

  1. What is your budget?
  2. What are you going to use the camera for?
  3. How often are you going to use the camera?

Know 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. For best cheap thermal imaging cameras, click here.

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 vend ducts in your house you probably do not need a very expensive camera with lots of advanced features. 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 camera. On the other hand, if you have your own business doing building inspections and will be using the camera every day for earning your living then it makes sense to spend more money.

Remember you can always upgrade and using your current camera to partially fund your next purchase.
