They need sensors that listen for gun shots. As long as you have more than three, you'd probably be able to locate the position of the gunshot pretty fast. They could instantly train cameras on the location. Ideally the cameras would have IR for nighttime surveillance and also the ability to read license plates and take decent shots of faces. As soon as this happens they would alert the servers. The servers would alert dispatch. Dispatch could send officers to that location. If their squad cars have the ability, you might even be able to forward images of the suspects directly to the car as well as real-time footage of the scene.
That's just some kind of sensor that listens for gunshots, a microcontroller, and little airship drone to mount this stuff on, and a wireless connection (i.e. 4G). Really, you could do most of the processing at the server level.
That's basicaly how it works already. CCTV is combined with the Shot Spotter. Not sure exactly but Shot Spotters are already a thing I know that.

Our acoustic sensors identify and time-stamp specific impulsive noises; our system classifies and triangulates the location and type of gunshots within 10 feet; then our experts validate they are gunshots - all within 30-45 seconds of a gun being fired
