Best Cheap Thermal Camera

Best cheap thermal camera

Professional high resolution thermal imaging cameras, sometimes called infrared cameras can run over $10,000 depending upon what features you want or need.

Native high resolution thermal sensor, interchangeable lenses with auto calibration, extra wide temprature range and advances reporting with built in mics all drive up the cost of thermal cameras. But what if you don't need the most demanding specs and all the bells and whistles?

Fortunately, there are plenty of budget or “cheap” thermal imaging cameras that may fit your needs on the market. 

What is a thermal imaging camera used for?

Just because a thermal imaging camera is inexpensive does not mean that it is not capable of helping you with your projects. Some of the most common things that people will use budget thermal imaging cameras for are:

  • hand-o-right
    Detecting air-conditioning and heating leaks
  • hand-o-right
    Checking the seal on windows and garage doors
  • hand-o-right
    Checking for other inefficient sealing within a home or office
  • hand-o-right
    Checking appliance motors temperature to ensure they are not overheating
  • hand-o-right
    Automotive applications (engines, cables, connections, etc)
  • hand-o-right
    Detecting faulty circuits and breakers

How Much Is A "Cheap" Thermal Camera?

Low cost thermal imaging cameras can be divided into two categories; under $1,000 and under $500. Thermal imaging cameras under $1,000 are typically handheld, stand alone devices that have decent native thermal resolution for home use and light professional work. Some of these models such as the FLIR C3 and FLIR E4  have built in WiFi which makes it easier to share and create reports.

Thermal imaging cameras under $500 are typically thermal sensors that attach to a cellphone  and use the phone's display and processing power to capture images that later on can either be saved to phone memory or send them over the internet. The FLIR ONE and Seek Thermal are two good examples of cell phone thermal cameras under $500 which we are looking at here. For a first time purchase as long as you have an iPhone or Android device these can be the best purchase if price is the most important factor to you.

To be clear you will find many "thermal" temperature readers (IR thermometers) on the internet that are not thermal cameras but only measure temperature and display that on an LCD screen instead of an actual picture with different temperature areas shown in different colors.

Budget Thermal Cameras vs Professional and Industrial Thermal Imagers:

Below are some of the features that you may find in professional grade cameras. It is up to you to decide whether these are needed in your line of work:

  • Laser pointer for highlighting targets and autofocus 
  • Interchangeable lenses
  • Included Report Generation Software
  • Large Temperature Detection Range
  • High Resolution Images
  • Durability
  • Mic for voice annotation

Not to mention, it can capture time-lapse images and can start recording automatically when the alarm is triggered, so you don't need to go back to the settings. 

This thermal imager will detect the hottest and coldest part of an image through its cold and hot spot trackers. You get an intuitive device that allows blending of the thermal and visual image with one button. It has a heat map overlay at 0%, 25%, 50%, 75%, & 100%. This allows you to have a detailed view of the data you collect. 


As small as it is, the Fluke VT04A is quite a remarkable thermal imager. It can detect temperatures in the range of 140F to 4820F. It opens up just about every possibility of using a thermal camera from HVAC to building inspections, electrical, and mechanical industries. 

Because of its uncooled thermal sensor, this IR imager is a good choice for taking measurements from as far as 6ft away. It maintains a high level of accuracy thanks to its capability to align visible light in near and far modes.

This IR imager will store up to 10,000 images in its 4GB SD card storage. Now you can take as many thermal photos as you would like when trying to identify a specific problem in a system. It includes professional SmartView software that helps to go through the images and create relevant reports as well.

Battery Life, Warranty & Accessories:

Fluke VT04A is powered by four AA batteries instead of Lithium batteries like in the VT04. They give you more running time since it could be months before they ever need replacing and are cheap to replace. Continuous use of this IR imager yields eight hours of use. 

This infrared imager has a 2-year warranty and comes with a soft case for portability. 

  • It has quick hot and cold spot markers 
  • Center measurement box 
  • Six color palettes
  • Battery saving modes 
  • Focus free
  • Auto-monitor alarm
  • Isolated complaint about the readings being off by 5 degrees 
Fluke VT02 vs. Fluke VT04A:

Fluke also offers a cheaper option VT02 to their Fluke VT04A. It’s a pocket design that uses a similar uncooled pyroelectric ceramic sensor to capture thermal and visual images. It has three blended modes instead of five like the VT04A which are 25%, 50%, and 75%. 

We find the modes as the only major difference since it is also supported by SmartView analysis and reporting software as well as being powered by four AA batteries.


The Fluke VT04A IR Thermometer is designed to make your troubleshooting much easier at a low cost. This low-cost model gives you professional quality readings and images with no training needed. For visual and thermal benefits, the Fluke VT04 is a great choice for budget thermal imager. 

9. FLIR C2 Compact Thermal Imager

FLIR C2 Compact Thermal Imaging System

FLIR has redefined the way we view thermal imaging. It’s now about time you grab a thermal camera as part as your toolkit. These cameras have become affordable without making any compromises on the quality. Today, all eyes are on the FLIR C2. 

This camera is a standalone thermal imager designed for the building, inspection industry and home owners due to its small size. If you are a home inspector, contractor, electrician, HVAC specialist or plumber, this thermal camera is a must-have. It will save your client’s money on maintenance costs as it allows you to see energy leaks, plumbing clogs, and hot spots. This means you get to catch structural defects in time which can potentially help your clients save a lot of money.

Thermal Imaging with the FLIR C2:

This thermal camera uses a highly sensitive detector that can reveal heat changes from -140F to 3020F. This enables it to pick up subtle changes in temperature so that you can see a thermal pattern that will help identify the hidden insulation leaks. For an HVAC specialist, this is vital as it affects the comfort in a home. It affects indoor air quality when you have leaky doors, failing windows, etc. 

FLIR C2 Compact Thermal Imaging System

The FLIR C2 combines a thermal camera and the detector to bring out details in the images. It boasts a VGA 640 x 480 pixel resolution camera and an 80 x 60 pixel thermal sensor. Together, they create a 320 x 240 pixels resolution image. It’s incredible to see all the colors represented on the images which makes it much easier to identify the issue. 

The FLIR C2 stores up to 500 radiometric images in JPEG format. Each image can store 4,800 individual temperature measurements which come in handy in the analysis process. 

This camera also includes MSX thermal imaging enhancement. It adds critical details to the image by overlaying the thermal image on the regular image. It leads to instant recognition of temperature changes. This is because it presents a visible light picture and a thermal image on a 45-degree field of view making it super easy to see all the details in the image that you would not be able to if you were only looking at the lower resolution thermal image. 

The FLIR C2 has a 9Hz refresh rate. It is ideal for this type of thermal imaging since you won’t be out chasing after a moving target which would cause very blurry images. 

Battery Life and Accessories:

The FLIR C2 has a running time of 2 hours with a full battery. It comes with the charger, so it is just a matter of plugging in to recharge. You will also like that it is supplied with all the useful hardware to make work easier in the field. This goes for the lanyard where you can hang it around your neck or casually around your wrist. You also get a USB cable that’s useful for transferring images and videos.

FLIR Software:

Analyzing your images and adding the relevant information makes your report more conclusive. That’s why FLIR has their FLIR Tools Professional Reporting software. It is a top-performing software suite that has all the tools you need to show min, max, and average temp information, change color palettes, and add spot meters. 

Warranty Information:

The FLIR C2 enjoys the 2-10 warranty that applies to all FLIR’s handheld thermal cameras. The thermal detector is covered for ten years while the parts and labor get coverage of 2 years. You must register your new FLIR thermal camera on their customer care desk available online for the 2-10 warranty. 

FLIR C2 vs. FLIR C3:

The FLIR C3 is like the C2 in so many ways. From the size to the operation, but there’s additional Wi-Fi functionality. It allows you to perform wireless streaming to other devices like a tablet or smartphone. This camera also has area measurement and picture in picture mode which gives you more details and will save you time.
