— "James G. Beldock, a vice president at ShotSpotter, said that the system was not intended to record anything except gunshots and that cases like New Bedford’s were extremely rare. “There are people who perceive that these sensors are triggered by conversations, but that is just patently not true,” he said. “They don’t turn on unless they hear a gunshot.”
Seems like audio filters would only alert the monitoring center upon gunshots, but wouldn't it have to listen nonstop in order to find the sounds to trigger the alarm?"
