SDI Coaxial Underwater Camera, 4K HD IP68 Waterproof Stainless Steel Subsea Camera for ROV
Product Overview： The SDI Coaxial Underwater Camera is a professional industrial subsea surveillance solution built for high-precision, real-time underwater operations. Unlike traditional IP underwater cameras that suffer from encoding compression, frame loss and signal latency, this SDI coaxial underwater camera adopts pure uncompressed digital coaxial transmission technology. It delivers lag-free, high-fidelity video streaming while combining industrial HD imaging, ultra-low-light 24/7 night vision, strong anti-interference capability, and IP68 100m deep-water pressure and corrosion resistance. Ideal for ROV integration, offshore engineering, underwater salvage, and water conservancy inspection, it provides reliable professional visual feedback for critical underwater industrial tasks.

Core Product Advantages
1. Uncompressed SDI Transmission & Near-Zero Latency
Featuring professional SDI coaxial signal output, this underwater camera supports 100% uncompressed video transmission with latency below 10ms. It eliminates the frame delay, image distortion and data loss common to network camera encoding and decoding. Every underwater movement and structural change is displayed synchronously, fully meeting the real-time control requirements of ROV manipulation and emergency underwater salvage. With powerful anti-EMI electromagnetic interference performance, it resists signal disturbance from ship electrical systems, offshore machinery and complex marine environments. It achieves stable ultra-long transmission up to 300 meters with minimal signal attenuation, far more reliable than standard Ethernet underwater cameras.2. Industrial HD Imaging & Underwater Color Restoration
Equipped with a high-sensitivity industrial CMOS sensor and high-transmittance optical lens, the camera captures sharp, low-distortion subsea footage with rich structural details. Optimized exclusively for underwater environments, the built-in image algorithm effectively corrects typical underwater flaws including blue-green color cast, light attenuation and turbidity blurring. It accurately restores real underwater colors and textures, clearly identifying pipeline micro cracks, structural wear, suspended particles and terrain variations, delivering precise visual data for industrial inspection and engineering assessment.3. Ultra-Low Light 24/7 All-Weather Surveillance
Engineered for dark and turbid subsea conditions, this SDI underwater camera achieves excellent low-light sensitivity of 0.005Lux (Color) / 0.0005Lux (B/W). It produces bright, noise-free full-color videos in dim deep water and clear black-and-white night vision in total darkness. The adaptive intelligent fill light system automatically adjusts brightness based on water turbidity and ambient light, penetrating underwater haze, suppressing image noise and avoiding lens overexposure. It maintains consistent high-definition imaging in fresh water, seawater and muddy water, enabling uninterrupted round-the-clock monitoring.4. IP68 Deep-Sea Waterproof & Anti-Corrosion Durability
Built with integrated seamless sealing technology and marine-grade anti-corrosion aluminum alloy housing, the camera features top-tier IP68 dustproof and waterproof protection. It supports long-term continuous immersion in 100m deep water, withstanding high deep-sea hydraulic pressure, strong water flow impact, seawater salt corrosion and low-temperature aging. After strict industrial pressure and corrosion resistance testing, it effectively prevents water seepage, lens fogging and shell oxidation, ensuring stable year-round operation in harsh marine and water conservancy environments with an extended service life.5. Wide Compatibility & Simple Industrial Integration
This SDI coaxial underwater camera is fully compatible with mainstream industrial SDI displays, recorders, monitoring hosts and ROV auxiliary systems. It supports plug-and-play connection with no complicated network configuration or debugging required, greatly simplifying on-site deployment and system integration. The stable coaxial transmission structure avoids common network connection failures, ensuring continuous and reliable video output during long-term underwater industrial operations, perfectly suited for professional engineering scenarios.6. Compact Industrial Design & Low Maintenance
Adopting a lightweight, streamlined mini industrial structure, the camera is easy to mount on ROVs, offshore platforms, ship hulls and dam facilities. The integrated anti-aging, wear-resistant and anti-corrosion structure reduces vulnerable components and failure rates, significantly lowering daily maintenance workload and long-term operational costs. It supports long-term unattended underwater operation, matching the continuous working demands of marine and water conservancy projects.
