DNC-5C Universal 5.5-Inch Underwater Monitor with HDMI and SDI Inputs
DNC-5C is a universal sealed underwater monitor with both HDMI and SDI inputs, designed for professional underwater camera systems, live view, inspection, production, and monitoring workflows.
Instead of using separate monitors for HDMI and SDI camera systems, the DNC-5C allows operators to connect either signal type to one compact underwater monitor using compatible Dive And See waterproof cables and bulkhead connector systems.
Overview
The DNC-5C combines a 5.5-inch IPS display, 1920 x 1200 resolution, 600 nits brightness, HDMI 2.0 input, 3G-SDI input, sealed monitor housing, and approximately 5 hours of battery operation in one compact underwater monitor system.
The monitor uses rotatable low-profile HDMI and SDI input connectors. This keeps the cable path compact and ergonomic, reducing cable protrusion and improving handling on underwater camera rigs.

Why Use a Universal HDMI + SDI Monitor?
Many underwater camera systems use HDMI, while professional broadcast and long-distance underwater video systems often use SDI. The DNC-5C supports both input types, making it useful when working with different housings, cameras, or production setups.
With one monitor, operators can support HDMI camera housings, SDI camera systems, underwater live view, inspection cameras, and surface-style monitoring workflows using the correct Dive And See cable and bulkhead connector.
Image Quality and Monitoring Tools
The 600 nits backlight and 1100:1 contrast ratio help produce a clear image for framing, focus, and exposure control. The color temperature function allows better matching between the monitor image and the camera display.
Built-in monitoring tools help analyze incoming video signal and improve exposure, focus, and color decisions in the field.
Built-In Monitoring Functions
- Focus peaking
- Exposure assist
- Vectorscope
