DNC-2030 Underwater 3G-SDI Bulkhead Connector
Professional Waterproof M16 3G-SDI Bulkhead Connector for Underwater HD Video Transmission Systems
The DNC-2030 is a professional underwater 3G-SDI bulkhead connector designed for transmitting stable HD video signals from underwater camera housings to surface monitors, recorders, and live production systems.
Built for underwater cinematography, marine research, telemetry systems, industrial inspections, and broadcast applications, the DNC-2030 provides reliable 1080p60 SDI signal transmission using a waterproof M16 bulkhead connector design with integrated Water Block protection.
The connector is compatible with underwater housings from manufacturers including Nauticam, Salty, and Aquatica.
Why Choose 3G-SDI Underwater?
Unlike HDMI systems, professional 3G-SDI technology is engineered for reliable long-distance video transmission with secure locking connections, reduced signal loss, and improved stability in harsh underwater environments.
