Accurate Location means an incident located by the Subscription Services to a latitude/longitude coordinate that lies within a 25-meter radius of the confirmed shooters location (25 meters = approximately 82 feet). “Detectable Gunfire” incidents are unsuppressed discharges of ballistic firearms which occur fully outdoors in free space (i.e. not in doorways, vestibules, windows, vehicles, etc.) using standard commercially available rounds of caliber greater than .25. The Subscription Services Review Period is measured as the period commencing when the Incident Review Center (IRC) receives the alert and the first audio download to the time it is published to the City. The Subscription Services detects the sound of the muzzle blast and does not rely upon the sound of the bullet traveling through the air. Therefore, the speed in which the bullet travels (subsonic or supersonic) has no bearing on the Performance Rate. The Subscription Services location system is not a “point protection” system and is therefore not designed to consistently detect gunfire at every single location within the Coverage Area, but rather to Accurately Locate 90% of the Detectable Incidents in aggregate throughout the entire Coverage Area. There may be certain locations within the Coverage Area where obstacles and ambient noise impede and/or overshadow the propagation of acoustic energy such that locating the origin at those positions is inconsistent or impossible. The Performance Rate calculation is thus specifically tied to the Community Gunfire across the entire Coverage Area. Statistically Significant shall be defined as measurements and calculations which shall be performed as follows: (a) Across an entire Coverage Area; (b) Aggregating over a period of at least 30 days under weather conditions seasonally normal for the area; and (c) Provided that the total number of gunfire incidents being counted is equal to or greater than: (i) thirty (30) incidents for systems of up to three (3) square miles of Coverage Area, or (ii) ten (10) incidents multiplied by the number of square miles of Coverage Area for systems where one or more Coverage Areas are three (3) square miles or larger.
