The disclosed technology includes gunfire response systems and methods to detect gunfire, turn off lights when gunfire is detected, disable the lights from being switched on, and notify emergency responders. Such systems can help minimize ensuing risk following a shooting event by limiting the vision of a person who produced the gunfire. In some embodiments, the light switch system comprises one or more sensors. In some specific embodiments, the sensors include a microphone, infrared sensor, and optionally a camera. In some specific embodiments, the system is configured to detect gunfire sound, detect a type of gun that produced gunfire, and count of a number of shots of the gunfire.
