DNC-HD6 Portable Underwater 3G-SDI Inspection Camera System
The DNC-HD6 is a professional portable underwater inspection camera system that transmits live 1080p60 Full HD 3G-SDI video, receives continuous surface power, and provides remote camera control through one detachable SDI / power / control combo cable up to 100 meters.
Designed for offshore inspections, commercial diving, pipeline and infrastructure inspection, marine research, aquaculture, ROV support, underwater broadcast, and real-time monitoring, the DNC-HD6 provides a stable wired video connection without relying on underwater Wi-Fi or internal battery changes.
Key advantage: The external underwater combo cable is detachable and field-replaceable. If the cable is damaged or a different length is required, it can be serviced or replaced independently without replacing the camera housing.
One Detachable Cable for Video, Power, and Remote Control
- Live 3G-SDI video up to 1080p60
- Continuous camera power supplied from the surface
- Remote camera menu control from the surface
- Detachable, field-replaceable underwater cable architecture
- Selectable 30m, 50m, and 100m complete-system configurations
- Custom configurations available for specialized projects
The cable is often the most exposed part of an underwater system. It may be pulled, dragged, bent, stepped on, or damaged during field work. The detachable DNC-HD6 architecture reduces downtime and protects the long-term value of the camera system.
How the DNC-HD6 System Works
- The DNC-HD6 camera captures live underwater video.
- The detachable waterproof combo cable carries 3G-SDI video, surface power, and remote-control signals.
- At the surface, the SDI signal connects to compatible monitoring, recording, switching, or streaming equipment.
- The surface controller provides access to supported camera settings without retrieving the camera.
Diagram notice: The diagram explains the signal workflow. Connector orientation, cable routing, control layout, internal wiring, and physical connector appearance may vary by product revision or custom configuration. Refer to confirmed product photos, drawings, and approved wiring documentation before installation.
Why 3G-SDI for Long-Distance Underwater Video?
Professional underwater operations require a dependable long-distance live video path. The DNC-HD6 uses 3G-SDI for stable 1080p60 transmission and integration with professional monitors, recorders, switchers, converters, and streaming encoders.
- Reliable long-distance wired video transmission
- Professional locking BNC connections at the surface
- Low-latency live monitoring
- Direct integration with professional SDI workflows
- SDI-to-HDMI conversion available for HDMI surface displays
