Best Thermal Imaging Camera Reviews – 2019

A thermal imaging camera, which is a type of thermo-graphic camera that has the ability to form a heat zone image through the use of infrared radiation, is useful for firefighters, architects, and others who must work through darkness and other factors that obstruct clear visibility. More simply, these devices convert thermal energy, also known as heat, into visible light. With the use of infrared radiation as light, these cameras provide architects, firefighters, law enforcement, power line maintenance technicians, and others who need it in their line of work with the ability to see in sites, crime scenes, or areas, despite the presence of smoke, heat-permeable barriers, and darkness.

If you are in search of a thermal imaging camera, but are unsure of what you need to know and what you should be paying attention to throughout the shopping process, do not fret. These cameras are sophisticated and it can undoubtedly be overwhelming to figure out how and which to choose from all that are available to consumers. In this buying guide, we will supply you with helpful information and tips that will help you make the best purchase decision and decrease your overall time spent shopping.

Key Things to Look for and Know Before Purchasing a Thermal Imaging Unit

Here are some important things to know and look out for before you purchase a thermal imaging unit.

Although they are commonly referred to cameras, thermal imaging devices are actually sensors. Heat, which is also referred to as thermal or infrared energy, and light are a part of the electromagnetic spectrum, but cameras that can detect thermal energy will not have the ability to detect visible light and cameras that can detect visible light will not have the ability to detect thermal energy.

There are both simple and more complex types of thermal imaging cameras. Depending on what exactly you need and want, you have the option to choose from ones that are fairly basic and others that have more complex abilities and features.

Resolution and Sensitivity

The two key components to know about thermal imaging cameras are the detector resolution and the thermal sensitivity.

The detector resolution illustrates the number of pixels that the camera provides. The resolutions that you will tend to see on the market are 160 x 120, 320 x 240, and 640 x 480. A 160 x 120 resolution will produce an image comprised of 19,200 pixels, a 320 x 240 resolution will produce an image comprised of 76,800 pixels, and a 640 x 480 resolution will produce an image comprised of 307,200. With that said, your needs will determine which detector resolution you decide to go with.

Thermal sensitivity is the nominal temperature difference that the camera has the ability to detect. Although the number is small and seemingly unimportant, it actually has significant implications in regards to measurement capabilities and image quality. The majority of un-cooled cameras will consist of a thermal sensitivity of approximately 0.1 degrees Celsius.

Another key component to take into consideration is the temperature range. The temperature range of a thermal imaging camera lets you know the minimum and maximum temperatures that the camera has the ability to measure.

 

Frequently Asked Questions

Is there a difference between a thermal imaging camera and an infrared camera? – The answer here is two-fold. Thermal radiation and infrared radiation are essentially the same things, but that is if the radiation sources consist of temperatures that are comparable to the room temperature.

What is the useful life of a thermal imaging camera? – This depends, but it is usually somewhere between 10 to 15 years or longer provided that the camera is properly cared for and has maintenance if that is recommended by the manufacturer.
