The active shooter detection system installed at a Methuen school recently and demonstrated on Tuesday was put in place free of charge to the city, but the company behind it says it has a few interested paying customers lined up.
Shooter Detection Systems (SDS) is the Rowley-based company that installed its Guardian Indoor Gunshot Detection system in a Methuen school. (The city isn’t releasing the name of the school.) The system’s sensors can detect the sound of a gunshot and alert authorities. It also allows them to track the shooter before entering the building. SDS’s technology was developed in tandem with DARPA and Raytheon.
