Wall-mounted nonlethal device for defending against intruders

[Category : - Life-saving; Fire-fighting- CONSTRUCTION HOME IMPROVEMENT]
[Viewed 1129 times]

A non-lethal, but highly effective, system to defend school classrooms, businesses, and homes against an intruder. A person can create a "safe-room" by barricading themselves with any means possible. Our Barrier Box can be deployed from within that safe area, through the wall, and create a non-inhabitable environment on the other side of the wall/door.
Unlike lethal weapons to defend against intruders, there is no face-to-face confrontation needed, no risk of killing an innocent bystander, and can be used by nearly everyone.
