HELL CRY                                               Sound antiburglar wall
DR S **0

Description
   The device is a source of  intensive sound, which strength is just under the limit of human tolerableness. After the activation it generates an imaginary sound wall - a patented unbearable pattern, frequency and intensity noise which immediately modify  the behavior of the intruder (typically observed as automatic protective impetus to place ones hands on their ears), disables a effective bearing, the communication with accomplices and forces the intruder to the desertion from the intensity zone.

   The body of the device is constructed  from steel and aluminium profiles.
   Can be used also on the front side of the defence shields.
