It is believed that ghosts absorb the surrounding heat to gain energy. This means two things. The first is that when you step into a suddenly cold area, it is a sign that a ghost may be present. The other is that specially made devices, known as thermal cameras, that allow us to detect temperature, which we can use to tell if there is abnormal activity going on, including ghosts.
These devices are essential to see things that are undetectable to the human eye.
How Thermal Cameras Work
Thermal cameras look at the temperature in the area in front of you, and display any sudden change in the surrounding temperature. Warmer temperatures typically appear in warmer colors, like yellow and red; colder temperatures appear purple or blue.
The camera does not have to come in contact with the object itself to detect the difference. Once the change has been detected, it is converted to an electrical signal, which is then displayed on the screen in the form of dark and bright spots. The dark spots (cooler colors) are the places that are colder, and the bright spots are the areas that are hotter.
So if you are moving through an area, like a graveyard or known paranormal building like an abandoned hospital or prison, as you travel around the location, you may run into “cold spots.” These denote the possibility of a ghostly presence absorbing the warm air.
After coming into contact with a spirit, how you make contact is up to you.
Types of Cameras
There are many different infrared cameras. The features of these cameras will vary. No matter what you pick, they typically fall into one or two primary categories, as stated below.
Cooled Infrared Detectors
They have a cooling mechanism because otherwise, the camera’s heat would mess up the results.
Uncooled Infrared Detectors
These cameras don’t need any cooling mechanism as they are operated by a sensor that works at average room temperature.
There are many thermal cameras on the market that vary in designs, specs, prices, etc. While you are making a purchase, it is essential to keep the below factors in mind to help you decide what camera to buy. These factors include:
- The camera’s battery life
- Range of the infrared radiation
- Sensitivity to the change in surrounding temperatures
- Price of the camera and whether it’s affordable or not
- Quality of its images
Here are the three best-infrared cameras to consider:
With this article, we hope that you now know that ghosts do exist and can be easily detected with a thermal camera that is sensitive to slight changes in temperature and displays a good enough result for you to read and interpret their presence.
