Director, Campus Security, State University in New England

“Gunshot detection alerts are integrated with our mass notification system so while our officers know exactly where to go, our students and staff are getting the message at the same time, so they know where NOT to go. This system is a critical tool that will give our staff and students the best opportunity to act on our training and make lifesaving decisions.
