See What Your Eyes Can’t With the Best Thermal Imaging Cameras

Last updated: 17 Jan 2023
Whether you want to detect heat loss, identify the heat-emission patterns of objects, or localize fire hotspots, thermal imaging cameras are a great product to invest in. These special imagers turn heat into visible light, helping you inspect objects easily. They can even be used to help with rescuing people through smoke. But since these gadgets pack different temperature ranges, amounts of pixels, and levels of emissivity, finding the right one can be tough. But don't worry, we have already done the heavy lifting for you by reviewing some of the finest thermal imaging cameras for 2023 and diving deep into their unique features.

Best Thermal Imaging Cameras Buying Guide

This guide will help you understand some of the more crucial aspects of thermal imaging cameras so you can make an educated decision.

Why You Need a Thermal Imaging Camera

Accuracy

Thermal cameras help provide accurate reports of temperature gaps across objects. Whether your job deals with industrial inspections or rescue operations, you can benefit a lot from accurate heat readings from a thermal imaging camera.

Overcoming visual limitations

As the human eye is limited to seeing visible light, it can’t look through other colors of light like infrared rays. Thermal imaging sensors make it possible for us to see infrared rays and find issues based on thermal gaps.

Storing thermal patterns

More often than not, thermal imaging cameras support memory cards that allow you to store thermally detected objects and gaps. Having stored images leads to more productive inspections and rescue operations by letting you make decisions based on the information present in the images.

Factors To Consider When Picking a Thermal Imaging Camera

Resolution

Thermal cameras have different amounts of pixels that can be displayed on their screens. The more pixels a camera can show, the higher its resolution is. Opting for a higher resolution display is worth it since it offers more detail and better image quality.

Temperature range

The temperature range of a heat camera refers to the highest and the lowest temperature it can detect. You can opt for a temperature range according to your everyday needs. Heat inspection cameras that offer an adjustable temperature range are always a good solution since they have more versatile applications.

Storage

Many thermal imaging cameras allow for saving images and storing them on a camera’s built-in memory, removable SD card, or a USB drive. Whichever thermal camera you pick, make sure it lets you save images for backup and sharing.

Other Things To Know About Thermal Imaging Cameras

Adjustable parameters

The accuracy of your measurements will be affected when detecting low-emissivity objects, like shiny aluminum since they reflect infrared energy. A thermal imager with adjustable parameters is a good solution in these conditions. They offer more precision, even with low-emissivity substances.

Long-lasting battery

Heat inspection of industrial objects, large buildings, and firefighting spots can be time-consuming. So, if you want to make your inspection tasks more efficient, make sure your thermal imager offers a decent amount of battery life.

Tips for Using Thermal Imaging Cameras

Exploring the emissivity of different objects

Shiny surfaces like polished metals reflect infrared rays, leading to improper temperature readings by thermal sensors. So, we recommend educating yourself on the emissivity of various substances and how to adjust things accordingly for accurate thermal inspections.

A hot spot is not always an issue

Electrical hardware often overheats after consistent use, but that isn’t an issue. Similarly, there are many other cases where a beginner can easily misdiagnose a problem, leading to bigger issues down the road. So, it’s always a good idea to thoroughly identify the problem before making a decision based on an initial reading.

People Also Asked

Q: Can I use my smartphone as a thermal camera?

A: A smartphone can be used as a thermal camera in different ways, like by using a thermal detection app or attaching a heat sensor to it. But a smartphone-based heat camera will never be as effective for thermal inspections as a thermal imaging camera that’s specifically designed for this purpose.

Q: How much do thermal cameras cost?

A: Thermal cameras are expensive pieces of equipment that cost around $500 in most cases. This higher price is due to the expensive costs of the lenses and thermal sensors. The camera, the processing components, and other hardware also add to the hefty price tag of thermal imagers. 

Q: Can my thermal cameras see through walls?

A: Thermal cameras cannot see through walls. But you can use them to determine the motion of objects on the other side of a wall to find out what’s going on. This can be done by detecting heat patterns of objects close to a wall’s surface.
