The construction of smart maritime systems continues to advance, and unmanned vessel robots have become core equipment for port inspections, offshore monitoring, maritime emergency rescue, and aquatic ecosystem surveys. The complex marine operating conditions—such as high surface reflectivity, dense sea fog, significant daylight variations between day and night, highly saline and humid environments, and long-distance wireless transmission delays—easily lead to challenges including blurred visual data acquisition, video transmission stutters, and frequent equipment malfunctions. To address these issues, Kemore has specifically launched a comprehensive vision solution featuring the CM8230S high-definition zoom camera module paired with the CM2002HU encoding control board. This solution forms a fully integrated link—from front-end image acquisition to back-end video encoding and transmission—perfectly tailored to the limited onboard installation space of vessel robots and the harsh conditions of maritime operations. It comprehensively resolves industry pain points such as poor adaptability of unmanned vessel vision systems, insufficient imaging capabilities, and unstable long-distance image transmission.

1. CM8230S maritime-grade camera module, suitable for all-round, all-weather image acquisition by shipborne robots.

As the visual perception core of marine robots, the CM8230S features a 1/3-inch Panasonic 2-megapixel CMOS sensor equipped with a combination of 30x optical zoom and 32x digital zoom, offering a focal length range from 4.3mm to 129mm. At the wide-angle end, its ultra-wide field of view—71.3°—enables rapid full-scan coverage of entire waterways and harbor areas. At the telephoto end, its narrow 2.58° field of view allows for long-distance identification of buoys, damaged hulls, and floating debris at sea, striking a perfect balance between broad-area cruising and detailed detection of potential hazards. The complex lighting conditions encountered during maritime operations are effectively addressed by integrating ICR automatic day/night switching, WDR wide dynamic range, HLC highlight compensation, and 3D digital noise reduction technologies into the camera module, effectively mitigating issues such as strong glare reflections from the sea surface and dark shadows caused by backlighting. In standard color mode, the minimum illumination is 0.5 lux; when paired with a digital slow shutter, nighttime illumination can drop as low as 0.025 lux, ensuring clean and clear images even in pitch-dark waters during late night or dawn/dusk hours. Additionally, the camera incorporates an intelligent defogging algorithm that can penetrate shallow coastal fog and sea-level moisture, restoring the outlines of distant objects. Vibration caused by ship motion due to waves and swells can be effectively compensated for by the digital image stabilization feature. The camera also supports 24-zone privacy masking and 3-zone motion detection, making it ideal for inspecting sensitive areas within port zones and providing early warnings of anomalous targets in waterways. On the hardware level, the camera is compatible with the full range of VISCA and Pelco-D/P PTZ control protocols, and its adjustable baud rate settings allow seamless integration with onboard industrial control communications. It simultaneously outputs multiple signals—including HD-SDI, TVI2.0, and CVBS—eliminating the need for additional signal splitters and simplifying internal wiring within marine robots. The compact dimensions of just 50×60×93mm and lightweight design weighing only 240g ensure minimal impact on the unmanned boat’s payload. Operating reliably within a stable temperature range of -10℃ to +50℃, the camera is fully capable of withstanding harsh maritime environments characterized by high humidity and fluctuating temperatures.

2. CM2002HU Micro-Encoding Control Board—Building a Low-Latency Remote Video Transmission Channel for Ship Robots

Long-distance shore-based control is a core requirement for robotic ship operations. The CM2002HU encoding board serves as the central hub for video signal processing and transmission. Its ultra-small form factor—measuring just 50mm × 50mm—and featuring a standard 45mm mounting hole allows for easy integration into the hulls of various compact unmanned inspection vessels. The board operates on a DC12V power supply, making it an ideal match for shipboard power systems. Its transmission interfaces cover all possible application scenarios: HDMI supports 4K@30Hz input and loop-out, enabling seamless connection to the high-definition output of the CM8230S; it also features dual high-speed USB3.0 and USB2.0 outputs, delivering lossless HD video at 1080P@60Hz by default, significantly reducing video transmission latency and ensuring that the shore-based command center can simultaneously monitor real-time maritime footage, thereby mitigating navigation risks caused by control delays. Paired with the complementary CM2002U tail board, this solution is compatible with Kaimorui’s entire series of camera modules as well as mainstream onboard cameras such as Sony’s 6300 and 9520l models, making it suitable for both new robotic ship development and upgrades of existing equipment. Specifically designed for maritime satellite and narrow-band wireless transmission scenarios, the board incorporates optimized encoding algorithms that compress the video stream while maintaining high image clarity, effectively addressing issues like lagging and image distortion during long-distance transmission. Its minimalist integrated architecture reduces internal wiring within the vessel, minimizing interference from the complex electromagnetic environment at sea. This enables synchronized operation of image acquisition, gimbal command control, and video encoding, thereby lowering the overall failure rate of the robotic ship system.

3. Integrate software and hardware seamlessly to build a closed-loop visual operation system for ship robots.

Single camera modules or encoding boards alone cannot fully meet the operational logic required for unmanned vessels. To address this challenge, Kaimorui has jointly optimized both the software and hardware of the CM8230S and CM2002HU, enabling seamless integration among the three key modules: imaging, control, and transmission. The CM8230S’s multi-channel HD output signals can be directly connected to the input ports of the CM2002HU, while control commands—such as pan-and-tilt zoom, exposure adjustment, and white balance calibration—are exchanged bidirectionally between the two devices. Operation instructions issued from the shore-based control center are synchronized and responded to without any delay, significantly enhancing the smoothness of vessel robot operation. Both products feature a lightweight, compact design that greatly conserves the limited installation space inside unmanned boats, making them suitable for a variety of platforms including small inland inspection robots, long-range search-and-rescue unmanned boats, and port-security patrol robots. Thanks to their parallel multi-channel signal output architecture, these devices can simultaneously feed video streams to three distinct destinations: onboard local storage, remote transmission to the shore-based control center, and on-board display terminals. This allows dispatch personnel to concurrently perform on-site observation, video archiving, and remote command tasks. Furthermore, the unified hardware standards for dual-module operation—including wide temperature and voltage ranges—enable these devices to withstand the prolonged rough seas and frequent start-stop conditions typically encountered by marine robots, thereby extending continuous operation time and reducing the frequency of equipment downtime and maintenance at sea.

4. Deep adaptation to all maritime scenarios, expanding the boundaries of intelligent operations for ship robots.

The intelligent development of the marine sector has become an industry-wide trend, and high-performance airborne vision systems are the key enablers for unlocking the full potential of ship-based robotic operations. The CM8230S high-definition zoom module from Kaimorui, paired with the CM2002HU miniature encoding control board, boasts four core advantages—day-and-night high-definition imaging, low-latency and stable video transmission, robust resistance to harsh maritime environments, and compact, integrated design—to provide a standardized, all-in-one visual solution for robots across all types of vessels. With its professional hardware capabilities, this solution safeguards the intelligent monitoring front line of our blue waterways.
