Sound Streem – Antiloithering Wall

The device is a source of intensive sound signal, which is hearable only by young people – up to 30 years. Longer time of exposure is vexing. After the activation it decks the target territory with patented frequency and intensity noise which modifies the behavior of teenagers and push them to leave the intensity zone.

Can be activated by timer, remote control or passive infrared motion detector

It is an effective tool for dispersing groups of teenagers who loiter and behave in an antisocial manner-without direct confrontation.

The body of the device is magnesium/ aluminium cast.

Potential Application places:Subways, Car Parks, Railway / bus stations, Parks during hours of darkness to prevent groups of kids drinking, using drugs and vandalizing equipment, any other location where kids/adults congregate and cause damage
