Inferno Micro Sound Barrier

Award winning design – fits easily into public areas and private homes

Inferno Micro can function as a Sound Barrier or as a traditional siren. Inferno Micro effectively stops intruders in their tracks by generating a patented unbearable pattern, frequency and intensity noise. Sound Barrier mode is achieved by pairs or arrays of units. In siren mode, a single Inferno Micro covers areas up to 35 square meters/ 375 square feet. Larger areas can be covered with several units.

Installation of the Inferno Micro cheats the intruder of the few minutes that could be used between alarm activation and arrival of security or police, protecting the secured areas for that crucial period of time and continuing for the duration of continuous signal.
As a Sound Barrier, Inferno Micro causes a person to immediately modify their behavior, typically observed as autonomic protective impetus to place ones hands on their ears followed by body motion to immediately remove oneself from the intensity zone.
It is as a behavior modifying Sound Barrier that the value of the patented frequency pattern is achieved. It can be applied to quell, repel or control aggressive, malicious and riot behaviors. This aspect has been applied for protecting Russian nuclear weapons, stores, offices, and distribution plants.
As a siren, Inferno Micro is unmistakably loud with a unique intolerable attention getting frequency pattern that clearly stands out from background noise.
