A thermal infrared camera has a detector that is capable of achieving a high level of sensitivity to IR radiation and therefore can be used to detect objects by their IR radiation emission. The spectral response of the detector usually lies in the range of 8-14 μm.
This would allow the device to distinguish between objects based on their temperature and it is used in applications such as firefighting, surveillance, night vision devices, and air traffic control.

Best Thermal IR Sensor Cameras-Buying Guide
Features that you have to consider before buying the best thermal IR Sensor Cameras are:
The resolution of the thermal imaging camera determines the clarity of the images. It also reveals how well you can see the objects as you are hunting for them. The higher the resolution, the better and clearer the images will be.
The emissivity is a feature that helps in determining how well the objects and their temperatures are being displayed on the images. You should settle for a high emissivity if you need images that are very clear.
3. Frame rate-
The frame rate is something that you need to determine before you buy a thermal imaging camera. It should be high enough so that you don’t miss anything when you are using it.
4. Infrared sensors-
It is important that you get to know the number of infrared sensors of the cameras before you buy them. The more sensors, the better the quality of the images. The value ranges from 1 to 16.
5. Battery life-
The battery life of a thermal imaging camera determines how long it will last before it goes dead. You should only settle for a camera that has a long battery life so that you can use it for longer without any interruptions.
6. Trigger speed-
It is vital that you get to know the trigger speed of the camera before you buy it. The faster it is, the better it will be for your needs.
This is an aspect that you have to look into before you buy a thermal imaging camera. It should have an ample supply of power so that you can use it for longer without any interruptions.
If you are going to carry the camera with you all day, then it is paramount that you get to know its weight before making any purchase. You should only settle for one that is light enough so that your hands don’t get tired easily when you are using it.
This is something that you should determine before making any purchase so that you can easily find a good value for your money.
This is another thing that should interest you when buying a thermal imaging camera. You should only settle for one that has a longer warranty period so that in case something goes wrong, you can get it fixed or replaced without any hassles.
11. Customer reviews-
The customer reviews can help in determining which thermal imaging cameras are good and which ones are not worth your money.
How does Thermal Imaging Work?
Thermal imaging cameras detect differences in temperature of objects based on infrared radiation emitted by them and display these differences as heat images on their screens which can then be viewed by people as if they were looking at normal photographs or videos of these objects or scenes which is why they are also sometimes referred to as thermal cameras or infrared cameras despite their differences from each other in terms of their functions and capabilities which we will be taking a look at shortly.
Best Thermal Imaging cameras-FAQ
1. What is a thermal infrared camera?
A thermal infrared camera is an image intensifier that uses a thermal infrared sensor to detect infrared radiation from a scene and convert it into an electronic signal for display on a monitor. The camera is similar to an ordinary camera with the exception of an infrared-sensitive focal plane array or detector.
2. What is the difference between thermal infrared cameras and regular security cameras?
Thermal infrared cameras are more useful in low-light situations. As humans cannot see beyond 700 nanometers, thermal cameras are able to detect heat sources which are beyond our visible spectrum.
