    PKI 7430 Acoustic Warning Device

This PKI 7430 Acoustic Warning Device immobilizes everyone approaching you nearer than 200m. A directed audio signal with 80dB attains absolute threshold of pain. The sound beam can be used to assist law enforcement and security officers in riot control, maritime/perimeter security and counterterrorist hostage situations by allowing the operator to communicate with, and in some instances determine the intention of, a target individual over previously unattainable distances. At close range the device can be used to send an extremely uncomfortable ear-piercing noise to deter potential intruders or rioters. In anti-terror or hostage situations the PKI 7430 Acoustic Warning Device can be used to distract attention away from other activity or to project a clear voice signal over many hundreds of metres.
