Thermal Imaging Camera Buyer’s Guide

Thermal imaging cameras are highly-advanced heat sensory innovations, and it’s futile to expect that everyone will be an expert about this tool. Buying an efficient thermal imaging camera can be pretty hectic, especially for beginners. So, we’ve highlighted some FAQs and essential factors to consider before you invest your money on one of these cameras.

What makes a thermal camera any different from a standard camera?

Although the standard cameras are used for the sole purpose of clicking images, thermal imaging cameras are used to detect heat emissions. A standard camera lens is not engineered to identify any change in temperature. On the other hand, thermal cameras are excellent sensors when it comes to recognizing the minor differences in heat.

How does thermal camera work?

Before we understand how a thermal imaging camera works, we have to acknowledge that everything that surrounds us emits thermal energy. You may be surprised to know that even ice emits thermal energy. Now, it’s quite apparent that the hotter an object is, the higher it will emit thermal energy. 

Now, thermal imaging is equipped with a unique mechanism that helps the user visualize the heat levels that are invisible to the naked eye. However, it is much easier to understand how to operate a thermal imaging camera than it sounds. All you have to do is point it towards something and click images, if necessary.

Is it better to rent or buy a thermal imaging camera?

Well, we understand that the high-end thermal imaging cameras can be unreasonably pricey at times. However, it is so because the price of a thermal imaging camera varies according to the list of features it offers in exchange. In such a situation, renting a thermal imaging camera for one-time use may sound like a smart idea.

Now, renting allows you to explore different thermal camera brands. You will be able to gain higher expertise at using thermal imaging cameras if you rent these cameras. However, if you buy one, you’ll always have the tool nearby, which saves you from the hassle of booking appointments and renting. 

In this case, our best advice would be to rent a few different brands before you buy a final product. This way, you’ll be sure whether the product you’re investing in will provide you a satisfactory user experience.

How many types of thermal imaging cameras are there?

Mainly, there are three categories of thermal imaging cameras, such as handheld cameras, cooled detectors, uncooled detectors. Now, the cooled detectors, as evident by its name, are operated in cold temperatures. Likewise, the uncooled sensors are operated at room temperature.

Nonetheless, handheld cameras are quite efficient at detecting both warm and cold temperatures. As a bonus, these units are ergonomically designed for the convenience of its users. You can use these cameras for a long time by simply holding the device in your hand. 

What are the most important features to consider before buying a thermal imaging camera?

Buying the perfect thermal imaging camera for you is quite a task, and we don’t want you to do it without having proper info about its must-have features. That being said, these are the essential features you need to consider before you buy a thermal imaging camera.

Technician use thermal imaging camera to check temperature in factory

Imaging modes

As we already know, the primary use of a thermal imaging camera is to generate the thermal picture of a suspicious area or object. However, it is imperative to evaluate whether the camera you’ve had your eyes on offers versatile image modes. 

Although the old-fashioned units are good enough to click thermal images, the recent times are witnessing an increasing demand for the advanced ones that support fusion image modes. The fusion modes enable us to click both the normal and the thermal image, which comes with imprinted radiometric information.

LCD screen size

As its a camera at the end of the day, it’s significant for the unit to at least have a standard 3 inch LCD screen. Although there are various thermal cameras that offer around 5-7 inches of LCD screen, they can be a tad expensive. Nevertheless, you shouldn’t settle for anything less than a 3 inch LCD screen, as it may otherwise become tough for you to analyze the image on camera.

Refresh rate

Not to forget, it’s essential to check the refresh rate of the unit, when it comes to the thermal camera’s display.
