How To Choose The Best Thermal Camera For Home Inspections?
IR Resolution
The IR resolution of thermal cameras helps you figure out any potential problems and is measured in pixels. The higher the pixel count, the higher the image quality.
Lower IR resolution cameras still show the issues but they cannot pinpoint them.
For example, suppose that there’s a hot water leak in your house’s plumbing system and you are using a thermal camera to detect it.
With a low IR resolution camera, that leak will be vaguely shown on the screen as an increase in temperature that broadens outside of the pipe, but not the accurate spot.
With a higher resolution model, it can pinpoint this leak, its width, and the water flow. That results in a more precise and effective solution to stop that leak.
For home inspections, opt for a thermal camera that has at least 160x120 pixels.
Accuracy
The accuracy of a thermal camera tells you about the ability of this device to measure temperatures. It is measured in degrees F or degrees C.
It is recommended choosing a thermal camera that can detect temperature differences and show the accurate temperatures of the thing you are checking.
Temperature Range
The temperature range of a thermal camera is the minimum and maximum temperatures it can measure. For home inspection, the -13 to 700°F range is good enough if you are going to use a handheld camera and -4 to 250°F if that is a smartphone attachment.
Type
When it comes to thermal cameras for home inspections, there are two common types: handheld thermal cameras or thermal camera smartphone attachments. The choice depends on how long you are going to use it each time and your preference.
Handheld models provide better grip and comfort for extended use.
Meanwhile, thermal camera smartphone attachments are pocket-size, travel-friendly, and suitable for quick inspections. But take note that this type generally has lower IR resolution than the handheld.

FAQs
What's the difference between thermal and infrared cameras?
The difference between thermal and infrared cameras is: thermal cameras utilize mid- or long wavelength IR energy while infrared ones utilize short wavelength IR energy.
Why is thermal imaging so expensive?
Thermal imaging is expensive for some reason:
- The materials used for converting infrared radiation into an electrical voltage signal are at high prices
- The material used for lenses is unique, distinct, and costly
Is thermal imaging worth it for a home inspection?
Yes, it is. Thermal imaging helps you detect all the potential damage in your home so that you can figure out a prompt solution and minimize the repair cost.
If you plan to sell the house, thermal imaging lets you make a quick scan of the home to fix all the serious problems, then sell it at the best price.
What thermal camera can see through walls?
There's no thermal camera that could see through walls. Walls are too thick for any infrared radiation to go through.
Can I use my phone as a thermal camera?
Yes, you can.
There are some thermal cameras built to suit certain smartphones and work as thermal cameras.
In most cases, you will need to attach this camera to your smartphone camera. They will allow you to take thermal videos or photos, share findings, and send for documentation.
Conclusion
Picking the best thermal camera for home inspections is a difficult task. That’s why we did this deep dive into the world of thermal cameras, so you do not have to. Hopefully, our suggestions are helpful for you. Thanks for reading!
