8-Attachment F - Gunshot Detection System Functional Requirements.xlsx

This is a Functional Requirements document for a Gunshot Detection System being procured by the City of Detroit Office of Contracting and Procurement on behalf of the Detroit Police Department. The document establishes 28 specific functional requirements organized into ten categories: Detection System, Performance, Event Classification, Alerting, Visualization, Integration, Digital Evidence, Analytics, Security, Audit, Availability, Scalability, Administration, Maintenance, Training, and Future Capability. Core detection requirements mandate real-time gunfire detection with the ability to differentiate gunshots from fireworks, vehicle backfire, and construction noise, along with detection confidence scoring and triangulated geolocation of events. The system must achieve detection latency of 60 seconds or less with location accuracy within 25 meters as a preferred specification.

The proposed system must integrate with the RTCC monitoring stations and CAD/dispatch systems, display events on GIS-enabled maps with historical event replay and heat map capabilities, and automatically cue nearby cameras through RTCC integration. Additional integration requirements include compatibility with Genetec Security Center or equivalent video management systems and mobile access for field officers. The system must comply with CJIS Security Policy, implement role-based access control, encrypt data in transit and at rest, and maintain audit logging for all access and changes. Performance and operational requirements include 99.9% system uptime, support for phased deployment and expansion, centralized administration, remote sensor health monitoring, and operator and administrator training. An optional future capability includes support for integration with drone response workflows.
