RAYTOWN, Mo. -- A metro school district is adding an extra layer of security to keep your kids safe while in the classroom.
The Raytown School District initiated a new intruder defense system for all of its school buildings. In the video above FOX 4's Nicole DiAntonio takes you inside Southwood Elementary School on Raytown Road to see how the system works.
"It helps keep the door barricaded so that even if an intruder were to actually unlock the door, they still wouldn't be able to get in," the district's assistant superintendent, Travis Hux, said.
The device, which only takes a few seconds to install, was developed by a SWAT team medic who came up with the idea during an active shooter drill. It only cost $100 and is placed on the back of each door and clips underneath the door frame in a matter of minutes.
Dr.Hux says the device adds one more layer of security if an intruder where ever to get in a building.
Hux says the device will be installed in every elementary, middle and high school across the school district.
