Learning about the supernatural and unknown is a frequent pastime among people as well as a profession.  Seeking ghosts, spirits, and other paranormal evidence goes well beyond what we have all seen in Ghostbusters.  In fact, seeking paranormal evidence isn’t just for amateurs but has become a full blown profession.  In the past ghost hunters and paranormal enthusiasts had to rely on their senses and primitive technology.  Today, paranormal researchers and scientists have a much wider selection of tools available to them to capture ghost video, photographs, and sound frequencies.

A ghost video is one that shows evidence of a poltergeist, ghosts, spirits, or just about any other entity that may be thought of as a ghost.  In order to capture paranormal evidence on camera a good video camera should be used.  Ideally, the camera should be a digital video camera with a night shot feature which emits an infrared light.  The infrared light reflects off of most objects and back into the camera lens.  Any warm object will also emit its own infrared light.  The use of infrared is one way in which the thermal evidence of ghosts is captured on camera.  This can also help detect physically feeling cold spots which may be inhabited by ghosts or spirits.

In addition to the use of infrared light in capturing ghost video, other techniques are also used which can include Electronic Voice Phenomenon (EVP), other forms of thermal imaging, and Electromagnetic Frequency (EMF).  When attempting to produce a ghost video, many paranormal researchers rely on thermal cameras, which are quite expensive.  Until most researchers can actually afford these devices, they simply use camcorders and digital video cameras alone.
