What Should I Look For When Buying a Thermal Imaging Camera?

Before buying a thermal camera, you should look for the ten most important things. The things you must have to look for in a thermal camera are:

1. Resolution

The number of detector pixels on the sensor is the detector resolution. More pixel’s equal higher resolution. Furthermore, a lower spatial resolution value demonstrates better image quality and detail.

2. Focus of the camera

One of the most critical aspects is the focus. There are some common focuses in the thermal camera like manual focus, autofocus, laser-assisted autofocus, etc.

3. Temperature range

The temperature ranges your thermal imager requires on the maximum and minimum temperatures you will experience during your inspection.

4. Lens Option

A camera with interchangeable lenses allows you more flexibility, allowing you to check a wider variety of equipment and circumstances.

5. Saving Images /Additional data

Internal memory, a disposable SD card, or a USB flash drive may be used to save infrared and digital files, as well as voice notes in some cases. It’s essential to keep photos and other relevant data to various media for backup or sharing.

6. Palettes of colors

A monochromatic palette, such as grayscale or amber, helps to highlight subtle differences. High contrast palettes will make it easier to spot apparent flaws quickly. In the camera or the app, you should be able to adjust the palette.

7. Color Alarms

These can be used to quickly identify locations that are outside of normal temperature ranges.

8. Battery Life and Type

Look for a battery that has convenient features, including a charge level indicator. Nothing is more stressful than beginning an inspection without understanding how the batteries are doing. Take into account how long the battery will last and how fast it will charge.

9. Markers for Spots

Label specific temperatures on your image to compare simultaneous temperatures from different points on the same idea.

10. Reflected Emissivity and temperatures

Surfaces with low emissivities, such as shiny metals, will reflect infrared energy from other materials, causing your image and measurement precision to be thrown off. When selecting an image, look for the option to change parameters.

Thermal Camera Guide to Avoid Common Home Inspection Mistakes

Thermal Camera Guide

People make mistakes while using a thermal camera. Some of them are very common. With some simple care, you can avoid those mistakes. The standard errors during inspection people make are:

1. The most popular blunder is misinterpreting photos.

When examining a home with a FLIR camera, you can find cold spots, hot spots, and patterns that do not make sense and are easy to misinterpret. It takes practice to interpret thermal images correctly and identify damp areas, air leaks, possible mold issues, water leaks, termites and other insect infestations, missing insulation, and other issues.

2. Errors in Temperature Measurement

When it comes to taking an accurate temperature reading, it’s easy to make mistakes. While FLIR products designed for home inspections typically have a +/- 2% accuracy range, certain materials (such as shiny metal) will drastically alter the temperature your camera displays.

3. Be mindful of your tool’s limits

It would be fantastic if the FLIR ONE Pro could meet all of your thermography requirements. Although entry-level cameras such as the FLIR ONE and FLIR C3 are excellent tools, they have limitations. Moreover, you are restricted by the hardware and what you know how to do with it, as with most devices.

These are some common mistakes people make, and avoid these mistakes, and there is a thermal camera guide that will help you in this situation.

Frequently Asked Questions

We have gone through some questions answer to get some more information about the thermal camera. From the question-answer, we will highlight some important things with you.

Can thermal cameras see-through metal?

Thermal imaging cameras cannot see through metal. The LW thermal camera cannot see through even transparent glass.

How far can thermal cameras see?

Temperature variations of most cameras can detect 1°C or better. Moreover, thermal cameras can see as far as the eye can see in most cases. The object’s size and contrast decide whether you can “see something” at a given distance.

How does thermal imaging work?

the thermal cameras detect the temperature of the object, capturing the image using infrared lights.

Is thermal imaging safe?

If the technology is used for the right reason and in the right circumstances, then using thermal cameras is totally safe.

Why is thermal imaging so expensive?

As the most advanced and unique technology is used to record thermal imaging, it is expensive than regular cameras.

Final Word

Our journey to the best thermal camera for PCB inspection ends here. In short, we will suggest you have the FOTRIC 225 Pro Thermal Camera because this one qualifies as the Best Thermal Imaging Camera for Body Temperature.  When you attach the camera to tablet PCs, the system can perform sophisticated temperature analysis and basic maintenance tasks, both significant other components of the mentioned thermographic device Windows software and PC hardware.

Hi, I am Richard Bevill, I am a businessman and tech-blogger. I have a shop where I sell different types of thermal image cameras and their related accessories. Because of my business, I have to face so many clients of thermal image camera users. During my business hours, I find that many of my clients face difficulties with uses, maintenance, not getting the exact amount of service, buying the wrong one. All those problems they face because of their lack of knowledge about thermal image cameras.
