All About Thermal Cameras

 

Thermal cameras are not like other types of cameras because here, the images are formed through infrared radiation. This is sometimes called as Forward Looking Infrared or FLIR cameras with wavelengths of approximately 14000nm. As a matter of fact, this is way beyond the wavelength used in typical cameras that are at least 450 to 750nm range and forming images by using visible light.

 

As a matter of fact, there are various applications that are using thermal cameras like industrial security, high value site protection, perimeter security, border security, deployable security, force protection, asset surveillance, coastal surveillance, urban surveillance, port security as well as airport security. Every living thing emits some kind of thermal energy and this thermal energy is converted to visible images through thermal cameras. Later on, these images are being represented in forms of thermographs.

 

When compared to visible spectrum cameras, flir thermal imaging is much expensive. The reason for this is that, the device is converting thermal energy into visible images. In normal camera, pictures taken will depend on the light around. Therefore, we usually get better quality images if the photo is taken in a bright setting otherwise, the quality of photo is quite low.

 

On the other hand, when a thermal cam is used, it functions very well in almost any type of lighting condition. There is added vision inside the infrared spectrum which expands the vision of whichever object is seen. The thermal temperature that a particular object is emitting can be viewed in thermal cams. They are detecting and interpreting emissions and at the same time, providing users with good quality images even if there's no or very low light.

 

We usually come across on two kinds of thermal cameras. One is the cryogenically cooled and the other version is un-cooled. When using un-cooled cameras, it can operate at room temperatures only and have infrared detector elements. Normally, these cameras have built-in batteries, make no noise and can be activated almost immediately.

For the cryogenically cooled cameras however, these are often on the higher end of spectrum and can be damaged due to rough use. Fact is, these cameras types have some elements in their containers that can cool them to even below 0 degree Celsius or 32 degrees Fahrenheit. Apart from that, they have remarkable resolutions while their sensitivities allow users to observe minute differences similar to 0.1 C or 0.2 F even if these cameras are positioned at a distance that's greater than 300m or 1000ft from the object.
