A polygraph machine records the body's involuntary responses to an examiner's questions in order to ascertain deceptive behavior. The test measures physiological data from three or more systems of the human body-generally the respiratory, cardiovascular, and sweat gland systems-but not the voice.
When honesty and/ or trust are questionable in your relationship, a lie detector test may be the only alternative means of obtaining the truth.
Polygraph examinations are utilized as an investigative tool to assist in determining the truth when members of your family, friends and acquaintances, or employees become suspects when a theft has taken place. A lie detector test can help eliminate suspects and determine who is involved in or have knowledge of thefts of money or property, embezzlement, or vandalism. Polygraph testing also can help in determining the validity of potential harmful accusations.
At Guardian Security, we provide accurate, reliable and confidential polygraph testing in the New Jersey.
