Top Thermal Cameras Sorted By Professional Application

Thermal cameras have been glorified in Hollywood movies like Mission Impossible and James Bond as ultimate game-changing devices only used by highly trained and highly paid government assassins.

While there are some lethal applications, such as thermal imaging rifle scopes, a vast majority of heat-sensitive cameras are used in much more mundane tasks in common consumer-focused industries like home inspection, electrical inspection, HVAC estimations, automotive diagnosis and home security.

If you are in the market to buy a thermal imaging camera it makes sense to first understand a little bit about how they work and the technology involved so you can make a more informed purchasing decision later on.

How Thermal Imaging Cameras Work

All cameras use light to develop an image. Traditional cameras use visible light, that is light waves ranging in 300-800 nanometers in range. Thermal cameras capture infrared radiation, which is not visible yet omnipresent, to form their images. Thermal cameras have sensors that capture IR wavelengths of up to 14,000 nanometers (compared to 800 max of traditional cameras).

So we have increased sensitivity and the ability to read infrared light. Infrared light is essentially electromagnetic radiation, which forms waves similar to visible light, just much longer, so long in fact the human eye cannot detect them. Thus, special rare metals and electronic technology is used to capture these long radiant waves and converted to digital displays that the human eye can read.

If you have an engineering based background and want to really geek out on the specific science behind thermo imaging tech we recommend this resource.

Depending on the application IR cameras and imaging devices can vary drastically in size, technology and obviously price.

For highly sensitive applications, like scanning living creatures to detect sickness or disease very sensitive, cryogenically cooled devices are used. Cooling the device allows it to capture greater heat wavelengths compared to room-temperature/non-cooled devices.

Below we dig into the most popular cameras available for immediate purchase online. We have broken the cameras down by their intended use to better sort out what camera brand is best for your specific needs.

Best Cameras for Home Inspection/HVAC/Automotive

Qualities most desirable for cameras intended for home repair, construction, inspection as well as automotive diagnosis applications include:

  • Brand reputation
  • Warranty
  • Durability
  • Ease-of-Use
  • Longevity
  • Multiple Modes

If we look at what is widely available on the market it is important to balance all of these factors when choosing the optimal thermal imager.

We have found the best candidates in a variety of price brackets to suit professional needs of all levels. A 4-person automotive garage will have different requirements than a municipal building inspector after all.

The top brands in this space are FLIR, and Fluke. FLIR makes a wide variety of imaging devices with some starting at under $500. They’re cameras can be found in narrow-focused gun form as well as broad-focused tablet form as found in the FLIR C2 System.

For lower temperature monitoring though the FLIR stands out in it’s sharp contrast and nifty MSX technology that allows overlays of visual image details onto the thermal image for better description and post-shooting editing.

The FLIR is also available with a matching FLIR moisture pen or a FLIR voltage pen for a complete diagnostic solution.

Best Thermal Imagers for Hunting Applications

When it comes to hunting the priorities change in terms of what features are most valuable on IR imaging cameras. There is no need to be emailing reports directly from your device like you can with construction-focused options mentioned above.

Instead a rugged case that will protect the electronics in inclement weather and ease of use are two of the biggest features when it comes to choosing a hunting-specific camera.

You don’t want to be messing around with tiny buttons and an infinite variety of settings when you are out in the bush, you want something that is dependable, has a solid warranty and has a large view screen.

Cameras (as apposed to scopes) are usually used for spotting as hunting the the dark is obviously a doozy. Night spotting however helps hunters determine whether desired game is present and can give and edge similar to how fish finders can provide an edge in fishing tournaments.

The best selling and most highly reviewed traditional thermal camera for wildlife spotting is the Leupold Night Vision Optics 173096 LTO-Quest handheld thermal imager with a 15Hz camera.

Leupold LTO Quest Thermal Viewer

  • 300-Yard detection range & 8 Color palette options
  • Gorilla Glass display maximizes durability
  • Features a 206x156 pixel thermal sensor with a 22° field-of-view

This isn’t the most sensitive of all imagers, with a 206×156 sensor and a fixed focus but it is one of the simplest to use with a hand-held shape, rugged exterior and three button interface.

Leuopold’s solid reputation as a quality maker of rifle scopes transfers to their electronics, evidenced by their assembled-in-America claim and solid “5-Year Leuopold’s Electronics Warranty”.

A slightly bulkier alternative to the Leupold handheld device is the retro-looking but time-tested Solomark monocular. This beast is one of the best selling spotting monoculars despite it’s massive size.

Running off 4 AA batteries this unit was probably engineered a decade ago but has since been updated to include a high res LCD screen for viewing and USB-connectivity for transferring images and video to your computer.

Top Monoculars for Law Enforcement & Reconnaissance

Everything reviewed thus far has been engineered and marketed to pedestrians for pedestrian uses like wildlife spotting, or for use one the job inspecting homes.

When it comes to professional grade equipment for law enforcement, border security, private security or private reconnaissance the level of precision and quality is taken to a whole new level.

The entry level model in terms of professional grade thermal imaging is FLIR’s top-of-the-line 431-008-31-00 Scout III-240. Yeah, it’s a mouthful and we’ll just refer to it as the Scout III from now on.

This is the most up-to-date and evolved version of FLIR’s Scout monocular, which has earned FLIR a reputation as a dependable solution that is not overly complicated.

When it comes to practical use in the field simplicity is king and the Scout III has it in spades with a compact and tactical design, massive eye piece, and simple four button interface, meaning the device can be operated with ease blindfolded or in high-pressure situations.

The combination of quality, brand reputation, compact form, and class-leading ease-of-use make the Scout III the gold standard in tactical infrared monoculars.

If the near $1,500 price tag scares you, there are a few more affordable options you may consider including the Firefield 5×50 Nightfall 2 and the Bestguarder 6x50mm TFT Night Vision monocular.

License To Shoot Words of Wisdom

When it comes to electronics and technology you very often get what you pay for. When making the final decision regarding which IR camera suits your needs most always consider the warranty and the features before you worry about price.

While some cameras push very close or even exceed the $1,000 mark, which may seem a bit steep, if you factor in how much your average iPhone product cost these days that figure seems very reasonable.

Furthermore, if the application is inspection related, or used for security, then the potential cost of device failure could be catastrophic, making investing in top of the line equipment a no-brainer.

The best process for making an informed purchase would be the following:

  1. Determine the primary application of the device
  2. Factor in requirements specific to said application (water proof for outdoor use, image recording for mechanical/HVAC use)
  3. Identify 3 models that fulfill the above requirements
  4. Narrow the choice down to 2 models based on average user review scores
  5. Choose the winning product based of whichever has the best warranty program

We sincerely hope this helps with your decision making process and that you find the right camera for your specific needs.
