"Raytheon’s Silent Guardian systems are the best non-lethal solutions available today,” said Mike Booen, vice president of Raytheon’s Advanced Security and Directed Energy Systems product line. “Customers worldwide are interested in these systems to protect their high-value sites and critical assets.”
Silent Guardian directs a focused beam of millimeter wave energy that travels at the speed of light producing an intolerable sensation that causes targeted individuals to flee or take cover. The sensation immediately ceases when an individual moves away from the beam or the operator discontinues engagement. Silent Guardian does not cause injury because of the shallow penetration depth of the millimeter wave and the safety features built into the system.
"It has no lasting effect" said A-Lan vonHörnlein Reynolds, director of Non-Lethal & Counter Terrorism Security Solutions, who told us that the system's effects on the human body have been reviewed by a panel of medical experts over many years.
