In recent years it has become a common theory that a ghost/spirit gives off an electro magnetic field which can
be detected by Electro Magnetic Field (EMF) meters. Most things in nature, both alive and inanimate, give off
an electromagnetic field. Many man-made devices such as electrical distribution boards, socket outlets,
electrical cables which are carrying current, computers, television sets, air conditioning units, appliances and
much more will emit a very strong electromagnetic field readings as part of their normal operation.
A paranormal occurrence or ghost may give off EMF readings in the range of 1.5mg to about 6mg depending on
the EMF meter you use. If you suspect that the reading may be of a paranormal nature, the reading should not
be a steady. Steady/constant readings are usually artificially created, whereas a paranormal reading would
fluctuate or even pulse.
tracks energy sources, and picks up on fluctuations in electromagnetic fields in the surrounding environment.
Because spirits are comprised of energy, it is believed that when an anomaly is present, it disrupts this
electromagnetic field.
EMF Detectors
Video cameras are an important instrument for an investigation.  Unlike still cameras they provide us with constant
visual and audio surveillance for review and observation.  The video cameras we use are equipped with infrared
capability and this is the mode we use.   With video any phenomena occurring can be documented in its entirety.  This
will show the length of time the phenomena occurs, what is happening, the conditions surrounding the phenomena, and
possibly even the cause of the phenomena..  
Wireless/Wired Infrared Day/Night
Color Cameras
 
Thermometers are an instrument that is also very useful   There are two types used regular digital thermometers and
infrared non contact thermometers.  When used on an investigation this will aid as a detection system for spirit
presence.  Rapid temperature drop of 10 degrees of more could indicate spirit presence.
