The Wausau School District says its schools are safer, after spending $200,000 on new security measures.
One of the newest security features is the "Buzz-In" system.
This is where the front desk has to buzz in any visitor who comes into the school.
Horace Mann Middle School in Wausau is one of the school featuring the new system.
Associate Principal Josh Ernst says the new system is just what the school needed.
"I think it absolutely deters people from coming into the building that shouldn't be in the building and I think that's the bottom line," said Ernst.
School district officials say they spent more than $200,000 dollars total on the new system.
This - following the tragedy at a Connecticut elementary school late last year.
"You look at the tragic events of Sandy Hook back in December, those are our youngest learners that somebody attacked, it causes us to take a step back and refocus where we want to put our priorities," said Jeff Lindell, Wausau School District.
The school district also added new security cameras and increased police presence on school grounds, but officials say the best tool for keeping schools safe is communication with students.
"It's important that we build the right lines of communication for our kids because our kids are the ones that are going to protect us from significant issues, and the vast majority of times that things occur in buildings somebody knows about it," added Lindell.
District officials agree the new buzz-in security might be inconvenient, but they say it is worth it to keep students safe.
Wausau school officials add that they have more ideas for keeping schools safe.
The issue is finding the money to pay for them.
