How does thermal imaging work?
In a thermal imaging device, there is a unique lens that only focuses on the infrared light that is emitted by all the objects that come into its view. This light is then scanned by an array of elements that are equipped with infrared detection capabilities. After this these elements develop a high-detailed temperature pattern that is called thermogram which is commonly known as a thermal image.
Why do thermal imaging cameras work better at night?
Thermal imaging cameras work better at night because the surroundings are colder at night and the warm objects emit a greater amount of infrared light at night due to the colder surroundings. When the sun is down, the difference between the heat producing object and the heat reflecting objects is greater.
Does thermal imaging work during the day?
During the day time, small capacity infrared cameras will only produce blur images. For this purpose, you will need a high-quality thermal camera. However, for near objects, the result with a regular thermal camera is better, but for the distant objects, you must require a top quality thermal camera.
What should I consider when buying a thermal camera?
First of all, you must look for a non-contact temperature measurement features of the device so that you can get a clear picture in the dark without touching anything. The temperature difference should be accurate, and a clear difference should be present. A clear temperature difference is not present if the image is blurry. If you want some extra details, then you should also look for the feature where you get to blend both visual and thermal images taken from the device for easy referencing.
Is there any difference between thermal imaging and infrared imaging?
There is no difference as such between the two particularly, when the objects emitting the radiations have temperatures that are easily comparable with the room temperature. However, for natural cold and lukewarm objects, the thermal emissions become infrared.
From the above assessment, FLIR C2 Compact Thermal Imaging System is the clear winner for us. It does cost a bit more than an average thermal camera, but it comes with more than handy features which drag it into this list of cheap thermal imaging camera. The amount of quality and characteristics to back the performance, usually don’t come in this price range.
