About
With over 30 years in the field and a team of more than 120 certified professionals, MDC Low Voltage Systems (McMillan Data Communications, Inc.) is one of the Bay Area's most established low-voltage contractors serving commercial, institutional, and public-sector clients throughout Oakland, CA and across California. For facility managers and property managers overseeing complex, multi-tenant, or mission-critical buildings, MDC delivers fully integrated low-voltage solutions spanning enterprise telecommunications infrastructure, structured cabling, data center buildouts, advanced audiovisual environments, access control, video surveillance, sound masking, mass notification, and wireless clock systems. Their design-build approach combines BIM modeling, pre-construction estimating, and cross-trade coordination to ensure seamless integration from concept through closeout — a critical advantage when managing occupied office buildings, healthcare facilities, K–12 and higher education campuses, tech campuses, life sciences facilities, and public works projects.

Post-installation, MDC offers responsive service and maintenance programs, along with 24/7 emergency support, reducing downtime risk for facility managers who depend on continuous system availability. Their white-glove equipment delivery, dedicated project management, and in-house field operations team mean fewer coordination gaps and a single accountable partner across telecom, AV, and security scopes. For Oakland-area property managers and facility teams seeking a low-voltage contractor with the depth, certifications, and staffing to handle enterprise-grade deployments across diverse commercial property types, MDC represents a proven, scalable resource.
