The best thermal-imaging cameras let you see the world in a whole new way and they're ideal for DIYers and contractors

The best thermal-imaging cameras in 2023 (1)

The best thermal imaging camerasallow you to explore the world in a whole new way. They let you see, measure, and capture temperature differences, accurately and from a safe distance.

Beyond the visible spectrum, there is an unseen world of heat radiation. Arty infrared film photographs aside, the practical uses of thermal imaging devices – also known as infrared thermal imagers – traditionally belonged only to military and professional budgets.

But now anyone can access thermal imaging, whether you want to spot heat sources in dark places – ideal for wildlife spotting – or identify where heat is being lost from your property. If you simply want to measure temperatures, you may prefer our guide to thebest infrared thermometers, but for HVAC, electronics, and plumbing these are now essential.

Find out more about how thermal imaging cameras work at the bottom of this guide. Below are the best thermal-imaging cameras you can buy right now, which I have either personally tested or sought expert advice and first-hand experience of.

The latest and best thermal-imaging camera for phones


Resolution: 160 x 120 px

Sensitivity range: -10°C to 50°C (14°F to 122°F)

Sensitivity: 70 mK

Dimensions: 37.5 × 35 × 149 mm (1.5 × 1.4 × 5.9 in)

Battery: 1.5 hours

Reasons to buy


Works on most phones


Measures up to 400°C (752°F)

Reasons to avoid


Battery life could be better


Not the cheapest option

The FLIR ONE Edge Pro is a wireless thermal-visible camera for camera phones and iPads. It's designed with a spring-loaded clip, which allows different users (or companies with several workers) to attach the camera to both iOS and Android smartphones and tablets. Unlike previous FLIR thermal imaging models that plugged into the bottom of the phone, the ONE Edge Pro doesn't actually have to be connected at all – and can be used up to 30 meters (100ft) away with a Wi-Fi and Bluetooth connection.

Is a compact, easy-to-use imaging device for builders, mechanisms, building inspectors and even homeowners who want to see how much heat their home is leaking! IP54-rated, it can measure temperatures up to 400°C (752°F) and has a maximum 1.5-hour battery life.

Teledyne FLIR promises that it's easy to recognize where problems are located and identify targets, thanks to FLIR's MSX (Multi-Spectral Dynamic Imaging), 160 × 120 (19,200 pixels) thermal resolution and VividIR, which combines multiple image frames together to deliver a clearer image.

Reasons to buy


3.5-inch touchscreen


Six thermal color palettes


Withstands 2m (6.6ft) drop

Reasons to avoid


Pricier than 128 x 96 C3 version


Turning on takes about 20 seconds



The FLIR C3-X and FLIR C5 are good-looking compact thermal imagers that are well suited to DIYers and contractors.With a rugged body that’ll survive a bit of workplace rough-and-tumble, both have two cameras and a 5-megapixel optical lens. The IR maxes out at 160 x 120 on the pricier C5, allowing it to take advantage of Flir’s MSX technology. This patented method uses an edge-detection algorithm on the higher-resolution visual light image, overlaying this with the IR image to make the picture easier to comprehend.

Both versions have a 3-inch touchscreen and can store around 500 images onboard to transfer via Micro USB. The ability to type notes via a touch keyboard can be handy, too. If you can stretch to it, the FLIR C5 model adds more analysis features and Wi-Fi so you can get images to your phone and to your software.

FLIR’s analysis software, FLIR Tools, allows you to change the color palettes and take readings from 4,800 measurement points in the image files, a little like using the eyedropper in Photoshop.

3. InfiRay P2 Pro

The smallest thermal camera in the world – and also great


Resolution: 256 x 192 pixels

Sensitivity range: -20˚C to 550˚C (-4˚F to 1022˚F)

Sensitivity: ±2°C or ±2% (whichever greater)

Weight: 9g (0.02lbs)

Dimensions: 27 × 18 × 9.8mm (1.1 × 0.7 × 0.4 in)

Battery: Power from phone

Reasons to buy


Very portable


High refresh rate of 25Hz


Thermal self portraits possible


Macro lens option

Reasons to avoid


Must choose Lightning or USB-C when buying


Doesn't align with camera (no hybrid images)

This amazingly compact device nevertheless beats more expensive alternatives in a number of ways. It only works when connected to a phone, and the connector – a lightning or USB-C plug – must be specified at purchase. But the app is good and offers a choice of easy or pro modes.

Another stroke of genius is the magnetically attachable macro lens, which is ideal for those examining circuit boards or other electronics, making this a very versatile tool. We worry that for some the connection might be delicate, but it is reversible (both USB-C and Lightning ports are) and you can see the level of detail in my full InfiRay P2 Pro review, in which I tested the device against simple insulation, plumbing, and electronics situations.

4. Seek Thermal RevealPRO

The best thermal-imaging camera for night use


Resolution: 320 x 240 pixels

Sensitivity range: -40˚C to 330˚C (-40˚F to 626˚F)

Sensitivity: 70 mK

Weight: 117g

Dimensions: 127 x 61 x 31mm (5 x 2.4 x 1.2 inches)

Battery: 4 hours rechargeable

Reasons to buy


High resolution thermal sensor


High refresh rate


Built-in flashlight


Emissivity adjustment

Reasons to avoid


Doesn’t capture video


No visual-light camera data

While the FLIR C-Series produces useful images in good light via MSX, this camera can do so at any time, since it doesn’t rely on visual light to boost its resolution. For our money, that makes it the best thermal-imaging camera for night use today.

Combined with its 15Hz refresh rate (many are only 9Hz), it can easily be used to spot animals or people in the dark, or through dense foliage. There’s also a 300-lumen LED light, should you want to surprise someone you’ve spotted in the dark. The simple menu system provides access to other useful features too, such as Level and Span adjustments (a little like manual exposure, allowing you to isolate a thermal range), and Emissivity adjustments (manual or pre-sets).

The fixed-focus camera works between 30cm (12 inches) and 550m (1,800 ft) and the 2.4-inch color screen is protected with Gorilla Glass. The 4GB memory can capture as many images as you’d need to (you can hold the shutter down if you like). For distance temperature readings, you can use the 4x digital zoom, though be warned that the resolution suffers.

5. Bosch GTC400C

Rugged pistol-grip thermal imaging camera for the jobsite


Resolution: 160 x 120 pixels

Sensitivity range: -40˚C to 400˚C (-104˚F to 752˚F)

Sensitivity: 50 mK

Dimensions: 95 x 63 x 233mm (3.7 x 2.5 x 9.2 inches)

Battery: 5 hours with lithium ion rechargeable pack; 2 hours with AA cells

Reasons to buy


Uses worksite rechargeable 12V batteries or 4xAA


Rugged build with built-in protective cap


Wi-fi and Bluetooth connectivity


Manual focus

(Video) 7 Best Thermal Cameras 2023

Reasons to avoid


Bigger investment than less rugged devices


Micro USB for data transfer, not charging


Accuracy +/- 3˚C (At this price 2 would be better)


No SD Card slot

This thermal-imaging camera is easy to use in the workplace but fully equipped with wi-fi and Bluetooth to share data with a phone. Held with a pistol grip, the image can be frozen with a trigger and saved using the camera icon below the screen. The design, with a built-in lens cover and rubber guards to protect the 3.5-inch screen, is strong and IP53 dustproof.

The device includes a picture-in-picture context function, which places the thermal image in the centre of a frame with a visual image around the outside providing context. Also useful on-site is the lock feature which fixes the minimum and maximum temperature (like an exposure lock).

Bosch also provides a supporting app so you can transfer images beyond the 600 the device will hold. This is great for additional analysis and report creation, and the radiometric data is there for later analysis (but it’d still be nice to store more onboard).

6. Seek Thermal CompactPro

The best phone-connected thermal-imaging camera for resolution


Resolution: 320 x 240 pixels

Sensitivity range: -40˚C to 330˚C (-40˚F to 626˚F)

Sensitivity: 70 mK

Dimensions: 41 x 20 x 15mm (1.6 x 0.8 x 0.6 inches)

Reasons to buy


Doesn’t need batteries


Mini USB or iOS Lightning


High-resolution IR sensor


Manual focus offers great range


High refresh rate

Reasons to avoid


Picture-by-picture parallax issue

This thermal-imaging camera also connects to your phone but provides more resolution (320 x 240 pixels) as well as higher sensitivity (-40˚F to 626˚F) than the Flir One – even the Pro version. And while that pushes up the price, it does make it a great choice for contractors, engineers, inspectors, and others looking for more detailed images.

With adjustable focus, the lens can be set on subjects as far as 550m (1,800ft). That’s not only handy for outdoor pursuits but allows you to take full advantage of the relatively high resolution to get sharp thermal images at any distance.

On the downside, while the FLIR One includes a visible light camera, the Seek CompactPro uses your phone’s camera to provide a split-screen picture-by-picture function, which is subject to some parallax issues.

On the plus side, the 15Hz refresh rate makes for better video (but can raise export issues when leaving the US, as it becomes “military grade”). Also, the app can give center-spot measures, or automatically highlight the hottest and coldest spots in a scene.

7. FLIR TG267

The best thermal-imaging camera for spot measurement


Resolution: 160 x 120 pixels

Sensitivity range: -25˚C to 380˚C (-13˚F to 716˚F)

Sensitivity: 70 mK

Dimensions: 210 x 64 x 81mm (8.3 x 2.5 x 3.2in)

Battery: 5 hours rechargeable

Reasons to buy


Great choice for industrial use


Spot measurement of temperature


One-handed operation

Featuring a laser and a continuous-scanning IR thermometer, the FLIR TG267 is a kind of hybrid between a non-contact thermometer and a thermal imaging camera.

The grip shape is ideally suited to tasks like car maintenance, since the one-handed operation is easy, and the cool bullseye-shaped laser dot makes it simple to direct the point of interest. The 2.4-inch color screen (refreshing at 8.7Hz) gives you plenty of confidence that you’re getting the right readings for your work, boosted by the MSX tech for a sharp view.

The generous battery will provide five hours' use in the workshop, and charges via the same USB connector, which can be used to offload the saved images –up to 50,000 of which will fit on the built-in 4GB. The system also allows for emissivity correction (manually or with four handy pre-sets) and includes a tripod mount at the bottom of the grip.

Enthusiast mechanics may prefer to hunt down the cheaper TG165, an earlier FLIR product aimed at this category that still features a laser and IR thermometer, while the near-identical TG275 can perceive an even greater temperature range.

High-resolution camera

Reasons to avoid


Menus are not quite as elegant as FLIR C series

The Seek ShotPRO is a compact IR camera that boasts a much better thermal resolution than its immediate competitors but, unlike some other accessibly priced Seek products, also includes the ability to mix visual light. The technology, SeekFusion, allows you to adjust a live overlay with an on-screen slider, a little like changing opacity in Photoshop layers. It lacks the edge enhancement of FLIR MSX, but on the other hand, the greater thermal resolution means that isn’t really needed.

The Short Pro, like the FLIR C3, is capable of Wi-Fi streaming (it partners with a free app called SeekView), though still boasts 4GB of memory to capture stills and video. Even without the app, the 3.5-inch touchscreen can be used with built-in analysis tools; you can create up to three boxes and monitor the minimum, maximum, and average temperature in each. Using the tripod mount can be handy for watching things change over time.

9. FLIR Scout TK

The best thermal-imaging monocular for value


Resolution: 160 x 120 pixels

Sensitivity range: -20˚C to +40˚C (-4˚F to 104˚F)

Sensitivity: 50 mK

Weight: 170g

Dimensions: 152 x 51 x 51mm (6 x 2 x 2in)

Battery: 5 hours rechargeable

Reasons to buy




Good-quality optics


Can store images & video

Reasons to avoid


Range restricts tasks

Combining a 160x120 pixel sensor with a 640 x 480 pixel LCD display means the Scout TK has the resolution and tech to identify a mammal – a person or a deer, say –hiding at around 100 yards (91m) away while being no harder to use than a traditional scope. That’s not a stunning level of detail, but without the scope your eyes might well not make out targets at a much shorter distance, giving this device a broad range of security and hobby uses.

The compact size and rechargeable battery boost the practicality; there will be no trouble fitting this into a decent coat pocket. The USB image download is convenient, and there's a cable included too, although no wireless transfer.

With a fixed field of view (20˚), the controls are not challenging:just brightness and the option to switch the color palette (White Hot, Black Hot, InstAlert, Graded Fire, and others). A single button handles recording, with a short press for a still and a long press for video. The 9Hz refresh rate is fast enough to make hand-holding practical.

10. CAT S62 Pro

The best thermal-imaging smartphone


Resolution: 160 x 120 pixels

Sensitivity range: -20˚C to 400˚C (-4˚F to 750˚F)

Sensitivity: 150 mK

Weight: 248g

Dimensions: 158 x 77 x 12mm

Battery: 4000mAh (Up to 2 days general use)

Reasons to buy


Super rugged construction


Fully waterproof


Full-feature Android smartphone


Indoor air quality monitoring

Reasons to avoid


Average visible-light camera


No 5G

The CAT S62 Pro is designed to take serious abuse, with the construction thatmeans that it can be dropped without having to worry about dents or cracking its Gorilla Glass 6screen. With an IP68 rating, CAT phones can be submerged in 3m of water, too, without fear of ingress. And thisindustrial design also comes with some useful additional features that you don'tfind on a phone – including a very capable thermal imaging camera built on the FLIR 3.5 sensor (160 x 120).

This is useful because it reduces the things you need to carry and avoids any connecting with IR cameras via Bluetooth or cables. The phone, too, is a perfectly serviceable affair with a 660 Octo Core 2GHz CPU that will runyour favorite apps and 6GB storage for them. Even if it may lack some of the refinements of thetopcamera phones, it has a 12MP Sony sensor, comes with Android 10, and supports the Android Enterprise feature set.

Note: the older CAT S61, still available in places, had a lower resolution IR camera, but offered laser measuring, offering an alternative with even more flexibility.

Visible light camera only 640 x 480

(Video) Thermal Imaging Camera: ✅ Best Thermal Imaging Cameras 2023 (Buying Guide)

FLIR’s rugged E-series, of which the E8-XT is the top of the line (I have reviewed the E5-XT, which has a similar build). It offers the advantages of the company’s image enhancement, which merges visible light with the IR thermograph for easier-to-understand imagery. At this price, it seems a little unfair that the visible light camera is only 640x480, but in this context, it works well enough.

Of more concern to a working professional is the combination of Wi-Fi/Bluetooth and the FLIR Tools app, which enables timely delivery of your assessment, with imagery, to clients. This is well-realized, easy to operate, and can also be used, via screen recordings, to capture video from the camera.

When you’re regularly working in rough environments, the E8 represents the kind of reliability you need. The autofocus makes it easy to use and the lenses and 3-inch screen are well-shielded in a drop-proof IP54 enclosure.

MR160 might be more cost effective

The benefits of MSX-enhanced IR imagery are clear in any scenario, but especially when you just want to get the job done. Here the extra contrast from the natural light camera combined with the detail (in line with FLIR’s patent) makes identifying moisture problems, air leaks, and insulation issues a relative breeze for anyone in the field.

The 8GB of internal memory will store up to 15,000 images, and their associated hygrometer readings and measurements from the laser measure, the beam of which is directed from a lens near the cameras.

Sensitivity: 150 mK

Dimensions: 56 x 30 x 14 mm (2.2 x 1.18 x 0.55in)

Reasons to buy


Accessibly priced

Reasons to avoid


-Low resolution


You need to get the right one for your phone (and provide the phone)

The IR202 is an ideal home inspection tool, made extremely portable by its compact design and piggybacking off the power from the host phone (Android only). At 15fps, the imaging is faster than some thermal images, though the 80 x 60 resolution means you’ll want to be relatively near your subject – meaning that hunters might want to look elsewhere for a tool to scan the woods.

It is nevertheless a noticeably higher resolution than the device’s immediate predecessor, the IR0102, which had a 32 x 32-pixel resolution. As a low-priced device, adding this to your toolkit is a lot less painful than some of the devices on this list, and with fuel prices on the rise, locating leaks (an ideal task for this adapter) could cover the cost surprisingly soon.

How thermal imaging cameras work

For the most part, the best thermal-imaging cameras work like regular ones, except that the image sensor detects invisible IR light and it is translated to a visual “thermogram”. This is what you see through the creature’s perspective views in The Predator and Prey.

Like visual cameras, these images are made of pixels but start at lower resolutions such as 80x60 pixels, or 0.003 megapixels. That sounds limited, but it's enough detail to pick out hotspots in wiring, for example.

See also Best thermal drones

Higher resolutions are always better, allowing you to work at a distance, which is especially important in security and rescue scenarios. Digitally overlaying the thermal image with a high-resolution, visible one can make understanding the picture easier, and many devices on this list do that.

The sensors are also of varying detail (150mK sensitivity means each pixel takes readings to the nearest 0.15˚C, so lower numbers are better). Meanwhile, refresh rates aren’t always high; 9Hz is typical, which is fine for locating hotspots, but not exactly cinematic.

Thermal imaging works in the dark, or through smoke, but can be fooled by the reflectiveness (emissivity) of a surface. Because IR is part of the electromagnetic spectrum, like visible light, it also has similar properties when it encounters lenses or rain. For professional use, it pays to read up a bit on understanding thermograms, but you’ll understand the basics the moment you power on your thermal camera. Depending on the software, you can also take retrospective measurements from the thermal JPEGs.

How we test thermal cameras

Although there are several of us on the team, including me (Adam Juniper), we generally test thermal cameras by using them in day-to-day tasks like inspecting ventilation/insulation, heating equipment (radiators, boilers) and plumbing (hot water pipes and taps). We also test any special claims made by the manufacturer about individual products, as well as the overall experience.

How do I choose a thermal imaging camera? ›

Apart from cost and quality, the two major factors that you should keep in mind when buying a thermal camera are Detector Resolution and Thermal Sensitivity. The Detector resolution is the number of pixels that the thermal imager can fill in a frame. More the pixels, more detailed the image is going to be!

What is the difference between infrared camera and thermal imaging camera? ›

Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Thermal imagers are passive, and only sense differences in heat.

What is the difference between FLIR and thermal imaging? ›

Thermal imaging cameras are actually sensors that detect heat rather than cameras (also called thermal energy or infrared). These devices detect radiation in a technical sense. The amount of radiation increases as the temperature rises. FLIR and Fluke cameras make pictures from heat, not visible light.

How far can MLX90640 thermal camera see? ›

Featuring an array of 32 x 24 pixels, the MLX90640 provides accurate temperature readings at a distance of up to 7 meters.

What is the highest temp thermal camera? ›

The FLIR TG297 combines accurate measurement with the ability to image temperatures as high as 1030°C (1886°F) in a one-of-a-kind diagnostic tool.

Can thermal imaging see through rain? ›

Although thermal imaging cameras can see in total darkness, through light fog, light rain, and snow, the distance they can see is affected by these atmospheric conditions.

Can thermal imaging see through fog and rain? ›

Fog and rain can severely limit the range of a thermal imaging system due to scattering in the droplets of water. The higher the density of droplets, the more the infrared signal is diminished.

How far can a thermal camera detect? ›

Additionally, the bigger the resolution, the farther your thermal camera can detect heat. Thus, a 320 x 240 resolution thermal device can detect accurately from a distance of 60 feet, a job a 60 x 120 resolution thermal can do at a 30-feet distance.

Can phone cameras do thermal imaging? ›

Made for iPhone® and Android™ top models, Seek Compact transforms your smartphone or tablet into a professional thermal imaging tool. By utilizing the power and convenience of your smartphone, our cameras make it easy to take thermal photos and video, share findings, and send for documentation.

What is the difference between night vision and thermal camera? ›

The only difference is a greater magnification – a night vision device will absorb any light available to it, magnify it, and then display the image in black and white. Meanwhile, thermal imaging works by measuring the heat signals of various objects and comparing them to each other.

What is the disadvantage of thermal camera? ›

Drawbacks or disadvantages of Thermal Imaging

Images are difficult to interpret in specific objects having erratic temperatures. ➨Accurate temperature measurements are hindered by differing emissivities and reflections from surfaces. ➨Thermal imaging cameras are not used for study of under water objects.

Can infrared see through walls? ›

Walls can block infrared rays. This means an object cannot be seen on a thermal imaging camera when hidden in the walls. The infrared rays cannot pass through the walls, which makes the person invisible on a thermal imaging camera.

Why are thermal imaging cameras so expensive? ›

High-Quality Germanium Glass Lens: While regular cameras use optical glass or plexiglass, thermal cameras use germanium to create their lenses in addition to regular glass. Germanium glass has a high refractive index, which is a measure of how light filters through a material.

Who competes with FLIR thermal camera? ›

FLIR Systems's competitors include Seek Thermal, AdaSky, MOHOC, Logos Technologies. FLIR Systems ranks 1st among 53 active competitors.

Can FLIR thermal camera see through walls? ›

Can you see through walls with thermal imaging Cameras? No, Thermal imaging cameras do not see through surface but detect surface temperatures. If a wall is thick enough to trap the heat on one side without leaking it into the other side then thermal imaging will not detect it.

Can you see alligators with thermal imaging? ›

These are 'cold blooded' creatures, but they're seldom the same temperature as their surroundings. A thermal drone paints different colors or shades of grey for different temperatures, so a croc or a snek on land or on the surface can sometimes be spotted by a thermal drone.

What is the coldest color on a thermal camera? ›

Thermal imaging cameras use color to show the relative temperature of objects: cold is purple, moderate is red, and hot is yellow.

Can a thermal camera see through a house? ›

Thermal imaging devices can't “see” through walls. But pointing a thermal camera at a building still reveals sensitive information about what's going on inside. Thermal cameras read the heat radiating off of an object.

Can thermal imaging see through drywall? ›

No, thermal cameras cannot see through walls, at least not like in the movies. Walls are generally thick enough—and insulated enough—to block any infrared radiation from the other side. If you point a thermal camera at a wall, it will detect heat from the wall , not what's behind it.

Can thermal camera see through clothes? ›

As Wired say: "But one odd side effect of infrared photography is that, in some cases, it can see right through clothing. Not always, and the clothes have to be pretty thin in the first place." The issue being that nowadays, the majority of high street clothes are indeed incredibly thin.

Can dogs see in thermal? ›

What is the difference between thermal and infrared? ›

Infrared imaging is very different from thermal imaging. While the former uses heat to produce images, the latter uses light. The light produces a super sharp image of your target area.

Can a thermal camera see rodents? ›

Thermal imagers are an increasingly popular, non-intrusive solution for finding pests in walls and other hidden places. From rodents to hornets to termites, many homeowners and building maintenance professionals are using thermal to quickly locate nests and avoid spreading chemicals like insecticides around homes.

Can a thermal camera see through windows? ›

The short answer to this question is no, thermal cameras cannot see through glass. This is because glass is a poor conductor of heat and does not emit any significant amount of infrared radiation. As a result, thermal cameras are unable to detect any temperature differences on the other side of the glass.
