  • Best Cheap Thermal Camera – Top 10 to Consider

Last updated on July 11, 2021

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

Native high resolution 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 cheap thermal imaging cameras for are:

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

How Much Is A Cheap Thermal Camera?

Budget thermal imaging cameras can be divided into two categories; under $1,000 and under $500. Some of the best 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 C5 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 mobile phone thermal imaging 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.
