They use microphones to detect gunshots. It works in a controlled environment but in an actual municipality the data needs enough "massaging" by human analysts to get what are still fundamentally low-quality tips it's somewhere between redundant and a waste of resources.

And those analysts are part of a law enforcement community that is rife with biases about crime and guns, which means most of the places where the system finds gunshots are where the biased people (who by default placed the detectors according to a bias) expect to hear gunshots.
