FEMA is conducting RFI market research to identify and evaluate innovative, stand-alone gunshot detection technologies for an Interagency Security Committee (ISC) Level V facility. Solutions of interest include acoustic, sensor-based, or other non-privacy-invasive technologies that enhance facility protection, threat detection, and security operations. Technologies must be authorized for DHS use, operate independently of privacy-sensitive systems, and not collect, retain, process, or transmit PII. Interested vendors should provide capability statements covering product specifications, detection and threat-response capabilities, stand-alone operation, privacy protections, relevant high-security deployments, DHS authorization status, and briefing/demonstration availability. If selected for further review, respondents may be asked to provide a vendor briefing and, when feasible, a live demonstration.
