The camera features a dual laser targeting system which provides a high level of precision. An IR thermometer gives a non-contact temperature reading, while a thermal imaging device shows the relative thermal properties of an aimed area in the context of its surroundings. The camera also has a spot ratio of 24:1 which means that it measures the temperature of a spot 1 inches in diameter. It detects object temperature at a range from -13 to +716°F.
Flir TG165 works perfectly on wide areas – it can scan the entire wall if you need it to. We can say that the downside is a quite low resolution (4800 pixels) but you should keep in mind that this tool is primarily designed for small household situations.
Flir TG165 is a very easy-to-use device. You can use it right from the box, without even having to read the instructions or search for a youtube video that would guide you step by step through the installation process. Things are simple with Flir TG165! The camera can store about 75000 images on its 8 GB SD card, but if for some reason this isn’t enough for you, the 32 GB SD card fits too.
The camera is sturdy and durable, it can endure all falls and bumps, although we don’t recommend you to try this intentionally. It’ also water-resistant which is a quite useful feature for those who plan to use the camera on the outside. Let’s not forget that it has a battery that can last up to 5 hours.

Criteria Used in Evaluation of the Best Thermal Imaging Cameras
We had a tough task of ranking the 10 best thermal imaging cameras on the market. All devices on our list were carefully chosen because of the excellent value they provide to the user, but we had to rank them from 1 to 10 according to their quality. We spend quite some time researching customers’ needs and requirements until we came up with the list of the most important things that every user wants to have. Here is the criteria applied in the evaluation:
As you already know, the overall performance of thermal imaging cameras is the most important thing that one should consider before making the purchase. This was also our number one concern when ranking the best cameras on our list. A thermal imaging camera has to have excellent resolution and it has to detect the proper temperature range to be useful. Of course, there are some cameras on our list that have lower resolution but they offer other features that compensate that lack. After all, while professionals might want to get the best resolution from their imaging cameras, most DIY enthusiasts and handypersons don’t need too much power from it. We tried to evaluate all the product according to their performance but we also had in mind various customers’ needs and requirements.
The design of the thermal imaging camera doesn’t seem as important as other essential features such as resolution and temperature range, but the truth is that it has a big impact on the overall quality of the camera. You don’t want to get a camera that isn’t suitable for your storage and transportation requirements. Also, the user-interface design can be very important especially if you’re a professional that needs the buttons to work even if you wear gloves. All of these little things can influence your overall experience and work with the camera.
Thermal imaging cameras are very expensive devices so we wanted to be sure that you’ll get the best value for the money. Some of the products on our list are less expensive, and we tried to rank them according to the overall performance and price. Getting a cheaper camera at the expense of some essential features wasn’t enough for us. Therefore, we tried to compare both the quality and price of every product and then rank them according to their overall performance.
Other Factors to Consider
You can always follow our criteria used in the evaluation of the best thermal imaging cameras to navigate to the best product for your personal needs. However, there are some things you may want to consider on your own.
What do you need a thermal imaging camera for? This tool can fulfill various purposes – law enforcement uses it as well as firefighters, industrial workers, and home inspectors. Determine the application first, and then you’ll know what type of thermal imaging camera you need.
Although it may not seem that way, compact design of thermal imaging cameras can be very important. If you’re going to keep your thermal camera fix mounted this is not the thing that will concern you, but people who need a portable device have to think about compact design.
We know how expensive are thermal imaging cameras, but you need this type of tool to be as good as it can get. If you have some extra money to spend on a new thermal camera, do it! It’ll provide excellent performance and you won’t be unsatisfied with the half-way features that won’t live up to your expectations. On the other hand, if you have a limited budget, search for the best resolution that you can find for the money. You can do this even at the expense of compact design or other additional features because this is less important than overall good performance.
Frequently Asked Questions
Q: What’s the difference between a thermal imaging camera and a night vision (or infrared) camera?
A: Thermal imaging cameras are actually sensors that detect heat, not light. On the other hand, cameras that detect visible light can’t see thermal energy. Thermal cameras detect temperature differences in objects or living organisms and translate them into an image. Night vision cameras take a small amount of visible light and increase it in that way that they produce an image completely lightened up by that light. Infrared cameras work with reflected light to make the image. Therefore, the main difference between these cameras is the use of light or heat – thermal imaging cameras are better in certain situations because they don’t rely on the presence or the absence of light.
Q: Can I hide from a thermal imaging camera?
A: Of course, you only need to block the signal that the thermal imaging camera detects. For example, you can hide behind hills, rolling ground or solid walls. It’s essential to hide behind things that will block your body heat. Overclothing can help too because bare skin emits more heat. You can also look for backgrounds that absorb heat, like rocks. Think about looking for other objects that have a big concentration of heat so you can camouflage your own body heat.
Q: Are there any thermal imaging apps for my phone?
A: There are various thermal imaging apps for androids and iPhones, and they work similarly to real thermal imaging cameras. Some of the apps are made just for fun, and they can’t really detect the heat, but there are ones that actually work this way. Many of them require built-in sensors, though, so not every type of phone will be able to pull this out. Keep in mind that those apps don’t come close to the abilities of thermal imaging cameras.
Q: Why are imaging cameras so expensive?
A: Thermal imaging cameras use different technology than visible light cameras. They require unique technology and components that are quite expensive. For example, thermal imaging cameras require a different type of lenses because regular glass can’t work with thermal sensors. Most thermal cameras’ lenses are made from a rare metal named germanium – and rare metal often means expensive metal. Lastly, thermal imaging cameras can also produce heat that can ruin a perfectly sharp image, so they require cooled sensors that will prevent this from happening. We listed only a few features that influence the high cost of thermal cameras, but you can find a wide range of essential features that make this tool unique and consequently expensive.
