Thermal Imaging Systems are like a regular camera in that they take videos or photos, but that is where the similarities stop. Thermal Imaging Systems measure radiation instead of light and areas that create more radiation, or are warmer, register in different shades or colors that those areas that have a lack of radiation. A photo of a person would show the area around the eyes, nose and mouth white to yellow, and the colder areas like feet and fingers might register as blue or black. Thermal Imaging systems are used for many different applications today.
Thermal cameras were used as far back as the Korean War and World War II to find targets for bombing purposes or to see the location of enemy troupes in the dark of night. Police use thermal imagers to see where people are located. They can tell if someone is in a dwelling or the positioning of people in a building enabling them to save hostages and capture perpetrators. Border patrol finds thermal imaging helpful in catching those that would illegally come across the border with or without illicit drugs and weapons. Fire fighters use thermal imaging to find people in forest fires or burning buildings.
Thermal imaging systems are used for surveillance as they can indicate intruders during the dark hours of night. Construction workers use them to find areas where insulation is not working correctly. A dark area around a window indicates more insulation is needed so that cold does leak in during the winter and air conditioning does not leak out during the summer. Utility workers use them to find hot spots in power lines and mechanics use them to find areas in in engines that run hot. Doctors are beginning to use thermal imaging to find infected tissue in the body and can even detect some types of cancers.
A popular use for thermal imaging is in paranormal studies. Paranormal entities that cannot be seen by the naked eye, either give off a great deal of radiation and are hot or create cold areas because of low radiation. They are easily indicated on a thermal camera in bright yellows and reds or in cool blues and purples.
Thermal imaging systems are very useful in many different ways, but they are very expensive. A good system will cost $4000 to $8000 although less expensive systems are on the market. If you are looking to buy Thermal Imaging Systems click here to go to nightvisiongoggles.com
