School shootings harden school

Development of S.H.I.E.L.D.™

After the Sandy Hook tragedy, a local Sheriff asked our founders if there was anything that could be done to harden a rural, remote school in his jurisdiction.  After studying all the school shootings that have occurred and analyzing what must occur during a school lockdown, our founders developed the concept for S.H.I.E.L.D.™ and presented it to the local Sheriff.  He loved it and paid for it to be installed at the rural school.

Recognizing the uniqueness of the system, our founders applied for and received a full patent on the system from the United States Patent and Trademark Office.

From these humble beginnings, S.H.I.E.L.D.™ now protects tens of thousands of students daily without changing the functionality or appearance of the school.  

What is S.H.I.E.L.D.™?

S.H.I.E.L.D.™, a patented system, functions as normal access control on a daily basis but upon activation it simultaneously compartmentalizes the school, notifies everyone in the building to lockdown and directly notifies law enforcement of the S.H.I.E.L.D.™ activation as well as 9-1-1.  All this occurs in 4 to 6 seconds.  Time is crucial in an active shooter incident.  The faster the school is locked down and the faster law enforcement can get on site, the more lives are saved in these horrific incidents.
