DEMI SYSTEMS LLC

DEMI SYSTEMS LLC specializes in the design, integration, and deployment of advanced physical security and audiovisual systems for federal defense and homeland security missions. Their core capabilities include the installation and modernization of closed-circuit television (CCTV) surveillance networks, the manufacturing of ruggedized audio and video equipment, and the integration of communications hardware tailored for high-security environments. The company demonstrates deep technical expertise in video surveillance system upgrades, secure audio amplification, and mission-critical AV infrastructure, with a focus on compliance with DoD and DHS security standards. Their ability to deliver end-to-end solutions—from hardware manufacturing to field deployment—sets them apart as a responsive, technically agile contractor capable of supporting time-sensitive infrastructure modernization across sensitive installations. DEMI SYSTEMS LLC has established a consistent presence with the Department of Defense and the Department of Homeland Security, delivering physical security enhancements and specialized AV equipment for military barracks, federal facilities, and critical infrastructure sites. Their work for DoD centers on upgrading surveillance systems at installations like JBSA FSH, while DHS engagements involve deploying integrated camera systems in high-traffic federal housing and operational zones, reflecting a pattern of supporting physical security modernization across both agencies. The company’s primary industry focus lies in Security Systems Services (NAICS 561621), where they provide surveillance infrastructure, and in the manufacturing of communications and audio-video equipment (NAICS 334290 and 334310), enabling them to bridge hardware development with system integration. This dual focus positions them as a niche provider for agencies requiring custom-built, field-deployable security and AV solutions. As a Service-Disabled Veteran-Owned Business headquartered in Alexandria, VA, DEMI SYSTEMS LLC leverages its small business structure and federal certifications to deliver agile, mission-focused support within the national security market. Their geographic proximity to federal decision-makers enhances responsiveness and operational coordination for time-critical procurements.
