I have been working in construction for almost 20 years and, after completing the renovation work, the most challenging thing is to verify that the facilities are optimal.
Sometimes, they had to spend months, to detect wiring faults or over-used power sources. A real headache to deliver on time!
However, that has recently changed with infrared devices. Some of these used to be of exclusive military use, but now they can lend their kindness to other areas, among which I have worked since childhood.
Knowing that with one of those devices with LCD screens and capable of recording images could save time and money I did not think about it anymore and decided to look for the best thermal imaging camera I could get in the market.
Having one of these for work will undoubtedly make things easier for you, you should look for what you need.

What is the best thermal camera?
To buy the best camera, you must be clear about what you are looking for.
If you only look for a camera that offers you infrared images or if you also have to store them, the selection is different. In the second case, one with WiFi, Bluetooth, SD memory and port for download is essential.
The resolution is also essential. A camera with a resolution higher than 480 pixels will be able to offer you temperature data in more closed spaces, those less than that will give you a more general picture.
Look at the price is not much, the more expensive more demanding and with greater qualities will be the device. The range is broad, can range from € 172 to € 18000, so you must select according to your possibilities.
Another quality is the possibility that the camera gives you images of visible light, apart from the infrared, this can be of great help in various areas since it will help you to find the problem areas quickly.
Other qualities such as focus, sensitivity and temperature are also determinants.
If you make comparative insurance, it will facilitate the selection, but if you are not sure yet, maybe this brief guide of suggestions can help you.

What is a thermal camera?
The thermal cameras are very similar to the conventional cameras, but instead of using the visible light to form the image, the (IR) is used. Also, they can operate at wave distances of 14 thousand nanometers, while the standard cameras have a range from 400 to 700 nanometers.
These devices register the different heat levels of an object and convert them into a video image; this is done thanks to the heat sensor that the device possesses.
What are thermographic cameras used for
When winter arrives it is necessary to keep our home warm, but sometimes it seems impossible to detect where the air currents are filtered, that is when the contractor can use his thermographic camera to identify these areas and thus apply the necessary solutions.
On the other hand, the same can be applied when summer arrives, and our house is too hot, with the use of this equipment it is possible to detect which is the object that is generating too much heat or even sees where the air conditioning is filtered.
Firefighters and the Environmental Protection Agency are some of the departments that frequently use these cameras.
In a fire, it is quite challenging to identify where the trapped people are, where the light is originating and even to see beyond the limits of human vision, thanks to the fact that these teams identify the different heat ranges of the objects they are exposed to. More comfortable to save the day.
The same case applies when spills or leaks of chemicals are generated, one way to detect them is through the use of thermographic cameras because the composition of the compound creates a different level of heat than the environment that surrounds it.
The military forces are perhaps one of the bodies that most use these devices. In the different missions, there is always a thermal camera that allows officers to identify hidden or camouflaged people and illegal substances such as marijuana. No matter how concealed it may be, the camera will always detect the difference of the object with the environment.
Several artists have achieved in these cameras a new world full of creativity when taking black and white photographs with these devices, and photographers manage to change the contrast of the image so that the elements that absorb the light darken while those that they reflect they become whiter.
The creators have found a new way to highlight different parts of an image and thus open a world full of possibilities for thermographic equipment.
What do thermographic cameras see?
The materials can emit heat or cold energy; the thermographic equipment detects the voltage and reflects it in images. The objects that surround us and even ourselves absorb, reflect and in some instances transmit power, each at different levels and speeds.
The human eye can only perceive a part of the electromagnetic spectrum: visible light. This is the light that we see every day, while the infrared (IR) radiation that represespecializedr percentage in the range is not visible without specialised equipment.
Characteristics of the thermal imager
The symptoms of the cameras can vary according to the equipment and the brand; the simplest ones allow to read the heat levels of exclusive crosshairs, while the most advanced ones give the user the option of choosing and comparing multiple crosshairs.
This type of camera uses three colour palettes, iron, black /white/grey, or rainbow. The user can select whichever one he likes according to the task he must perform.
Iron pallet of bus fuse bus
This type of palette is the most used by home inspectors.
Black palette / white / gray
This palette is perfect for identifying details in an image
This type has a higher sensitivity to show the different heat levels of an object.
What to look for in a thermal camera?
When you are in the search is this type of cameras is necessary to take into account that the cost can influence the quality, you must take into account what the equipment needs, that way you can acquire the right one.
Most of the cameras allow four adjustments to obtain a better image quality; these are a focus, changes of emissivity configuration, reflective temperature configuration and finally the thermal modification.
The resolution of the detector
This feature allows to describe the number of pixels of the equipment, among the most common recommendations, are 160 x 120, 320 x 240 and 640 x 480. The higher the resolution, the better quality the image will have because each pixel generates heat, and that translates into data for the team.
