How We Decided

Image capture and display is everything when it comes to thermal imaging cameras. We wanted cameras that can clearly define objects from their environment, especially for pinpointing unusual hotspots or energy readings. That’s why any model that didn’t have an above-average image display and capture was immediately taken out.

Once we thinned out the list, we then moved on to portability. We know that lugging around heavy equipment can be both tiring and worrying — especially if said equipment costs hundreds of dollars. The best thermal imaging camera would be pocket-sized or would fit neatly in the palm of your hand, but we made an exception for thermal imaging cameras with attached grips or handles.

Anything that we found to be too heavy, too big, or too oddly-shaped to be portable was struck from the list. The question we tried to answer for this category was, “Do we see ourselves comfortably lugging this around for more than an hour?” Anything we said “yes” to, we prioritized.

Finally, we focused on versatility. We asked ourselves: Is this thermal camera only suited for professional work, and therefore too complex for everyday use?

We also considered whether the unit is too simple or too basic for professional projects or any sort of fieldwork. We wanted to recommend models that struck the perfect balance between features, functionality, and accessibility.

Our ideal unit was one that both a homeowner with basic knowledge of thermal imaging and a professional with day-to-day engineering/plumbing/HVAC projects could use. As much as possible, we didn’t want any group to feel closed off from the options presented here.

Best Modern Buyer’s Guide

The Most Important Factors to Consider

  1. IR Resolution
    Make sure you look for the thermal resolution and not merely the display resolution of the camera. With pixel resolutions, the higher the number, the clearer the image it can produce. 80 x 60 (4,800 pixels) is usually the basic standard for imaging cameras.
  2. Temperature Range
    Wider temperature ranges improve the chances of more precise reading. Choose a thermal camera that captures images within the temperature range that your environment is typically in. For instance, a range of 15°F to 300°F usually covers the average home environment. For professional settings, a wider range of -40°F to 600°F is more preferred.
  3. Image Overlay
    This refers to the camera’s ability to combine visible light images with thermal images. This comes in handy when pinpointing anomalies or for sharing information with other people, such as clients and colleagues.
  4. Durability
    Portable and compact devices are often the ones most in need of some serious damage insurance. That’s why durability is an important feature to consider. There are some models, like FLIR TG165 that we mentioned earlier, that have a drop durability rating or assurance. Those are definitely ones you want to watch for.
  5. Longevity
    If you’re doing regular fieldwork or traveling, you may want to invest in a thermal imaging camera that doesn’t need constant charging. There are models out there that can go for 20-30 days between charges, depending on your usage. There are also models out there that can barely go 24 hours, even with light usage. These are the ones you want to avoid. As much as possible, choose a thermal imaging camera with good, rechargeable batteries. The alternative is a unit with an easily accessible battery dock for you to replace them every time they run out. This is a fine option if you’re only going to be using the camera for a finite time frame, like for a field trip or a DIY home improvement gig. But if you’re looking to invest in something you can use repeatedly over the years, get a rechargeable one.

Thermal Imaging Camera FAQs

Can thermal imaging cameras see through materials (like walls or clothes)?

Not exactly. Thermal imaging cameras aren’t like x-ray scans. They can’t “see” through solid objects in the visible, visual sense. However, they can detect heat coming through certain materials. For example, they may be able to detect a phone or a gun concealed beneath someone’s shirt because these would have vastly different temperatures compared to the person’s body. They could also detect pipes or wires beneath floorboards or tiles if these elements had rapidly different thermal profiles compared to their surroundings.

Is thermal imaging the same as night vision?

Nope. Night vision amplifies the available light in the surroundings to simulate bright light (or daylight) so a person can see their surroundings properly. It doesn’t detect anything special or out of the ordinary. You’d still have to depend on your own eyesight for that. As we mentioned earlier, thermal imaging cameras don’t rely on visible light. Even in pitch-black darkness, they can create thermal profiles for objects simply through temperature detection. Night vision cameras are much cheaper than thermal imaging cameras for this very reason.

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

In a nutshell, thermal imaging cameras measure the absolute temperature of the object. Infrared cameras—or IR cameras—measure beams of infrared light waves. Both are technically measuring infrared radiation, but thermal imaging cameras don’t need light to function. They can work in pitch-black darkness and are unaffected by smoke, haze, and headlights. Infrared cameras, on the other hand, need a beam to illuminate an area of interest. Practically speaking, thermal imaging cameras are most suitable for surveillance systems and nighttime fieldwork. Infrared cameras are most suitable for measuring environmental conditions in and around buildings, revealing likely structural issues like rot and moisture.

How much does a thermal imaging camera cost?

The price point of a thermal imaging camera primarily depends on your needs as a user. If you’re going to use a thermal camera for home monitoring and repair needs, you can typically find products under $500 that can do the job well. For light professional use, the price is somewhere between $500 and $1,000.

Why are thermal imaging cameras so expensive?

eThermal imaging cameras may be more on the pricey side, but given what they can do with the features they have installed? They’re definitely worth every penny. One can’t really compare their prices to those of visible light cameras for several reasons:
  • Thermal imaging cameras don’t need light to take pictures. Visible light cameras and IR cameras do.
  • Thermal imaging uses uncommon and highly refined technology that isn’t as easy to mass produce as the technology used for visible light cameras.
  • Thermal imaging sensors use a wavelength range that can still detect glass, which means you can’t just use ordinary glass for the thermal imaging camera’s lenses. Their lenses are typically made of germanium instead: a rare metal that can cost over $1500 per kilogram.
