Along China’s extensive coastline, with scattered islands and reefs and vast expanses of sea, challenges such as sea fog, atmospheric thermal turbulence, and drastic diurnal fluctuations in illumination pose multiple hurdles to coastal and maritime defense opticalelectronic surveillance. Conventional monitoring systems suffer from blurred longrange imaging, and their ability to detect and track small, fast surface craft and lowaltitude, slowmoving, small targets is inadequate, making it difficult to support coordinated multiplatform operations involving shorebased towers, shipborne systems, and coastal defense robots. The Kaimorui KC9480M ultralongfocus integrated module, paired with HK100C network control board, leveraging a 15–800 mm optical zoom capability and integrating marineenvironment image enhancement technology with comprehensive systemintegration interfaces, employs a domestically developed optoelectronic suite to address critical operational challenges in longrange target observation, evidence collection, and coordinated early warning for border and coastal defense.

I.15–800mm ultra-long focal length optical architecture, enabling seamless observation from the entire maritime domain to close-up details.

For coastal and maritime defense surveillance, the equipment must be capable of rapidly scanning vast sea areas while also conducting detailed analysis of suspicious targets several kilometers away; optical performance serves as the foundational pillar of the entire system. The KC9480M is equipped with a 1/1.8-inch CMOS sensor, delivering 2-megapixel HD output. Its 15mm wide-angle lens enables swift, comprehensive coverage of large maritime zones, with seamless zoom up to an 800mm telephoto focal length, allowing for magnified identification of vessels, personnel, and lowaltitude aerial vehicles at the horizon.

During on-site testing at a coastal vantage point, the device can resolve the silhouettes of small speedboats in the open sea at the telephoto end under bright daylight conditions. As twilight and dawn bring lowlight levels, the ICR infrared filter automatically switches, delivering starlightlevel sensitivity—0.005 lux in color and 0.0005 lux in monochrome—ensuring continuous imaging on darknight water surfaces and preventing target loss during the transition between day and night. Highmagnification optical zoom preserves native image quality, unlike the blur and distortion inherent in digital zoom, thereby providing verifiable video evidence for situational assessment of maritime bordersecurity targets.

II.Specialized image enhancement for sea conditions, mitigating interference from fog, heat haze, and vessel motion.

The nearshore environment is characterized by persistent seafog evaporation, intense glare from the sea surface, and atmospheric thermal turbulence. As a result, many electrooptical systems that boast impressive theoretical specifications experience a rapid decline in imaging quality once deployed on islands and reefs, leading to target misidentification. The KC9480M integrates optical defogging, antiheatwave algorithms, optical image stabilization, and a 120 dB ultrawide dynamic range, providing tailored performance to meet the complex meteorological conditions encountered in coastal and island defense applications.

Optical defogging attenuates seahaze interference at the optical level, extending visibility over maritime scenes in foggy conditions. The antiheatwave algorithm effectively reduces image distortion and jitter caused by thermal updrafts on the sea surface, ensuring stable imagery during longrange observation. A 120 dB ultrawide dynamic range suppresses sunlight glare on the water while preserving fine details of personnel and vessel structures in shadowed areas. Built-in optical image stabilization is compatible with mobile platforms such as lawenforcement boats and coastaldefense inspection robots, compensating for motioninduced shake and chassis vibrations. Paired with 3D noise reduction, it minimizes image noise in nighttime marine environments, delivering clean video streams that support reliable backend AIdriven detection and reduce falsealarm rates for boundarycrossing and intrusion alerts. H.265 encoding ensures efficient compression, making it well suited for narrowbandwidth maritime transmission scenarios and enabling more stable longdistance video backhaul.

III.Hong Kong100C Control board establishes a communication hub, enabling seamless integration across the border and coastal defense system.

Unlocking the full potential of a high-performance movement hinges on a stable and reliable control center, HK100C control board serves as the core component of the entire solution, providing comprehensive capabilities for command control, signal output, and protocol integration, thereby enabling efficient collaboration between the KC9480M movement and pantilt units, robot master controllers, and coastal defense command platforms.

This compact control board features RS485, TTL pass-through, network, and CVBS multichannel signal outputs, and is compatible with VISCA and PELCO protocols.P/D: A mainstream gimbal protocol that enables rapid integration with heavy-duty electro-optical pantilt units, shipborne electro-optical pods, and coastal defense unmanned robots. In field tests conducted as part of a coastal defense robot project, the robot’s main controller communicated via HK100C issues commands for zoom, focus, and preset position recall; the PTZ unit responds swiftly, enabling automatic tracking of maritime targets. With open ONVIF, CGI, and SDK interfaces, it seamlessly integrates with comprehensive borderandcoastal defense management platforms and supports radartriggered linkage: once the radar detects a suspicious target, the system automatically steers the PTZ gimbal and pan/tilt mechanism to the target’s bearing, facilitating confirmation and evidence collection. Equipped with dedicated alarm I/O ports, it can be incorporated into a complete coastaldefense earlywarning system. OEM/ODM customization is available to meet the diverse integration requirements of various borderandcoastal defense projects.

IV.Mult platform compatible deployment, establishing a coastal defense system featuring fixedsite duty and mobile patrols.

The new generation of intelligent border and coastal defense no longer relies solely on fixed outpost surveillance, but has shifted to a collaborative operational model involving shore-based facilities, ships, and unmanned platforms. The KC9480M is designed to operate across a wide temperature range, HK100C control board is compact, reducing the complexity of system integration, and the two can be paired to accommodate a variety of coastal defense platforms.

In shorebased deployment scenarios, the optical module is paired with a saltsprayresistant, temperaturecontrolled enclosure and a heavyduty pantilt unit, mounted on island watchtowers or coastal vantage points to enable routine longrange surveillance of coastlines. In maritime applications, leveraging its optical image stabilization, the system is integrated into lawenforcement vessels and nearshore unmanned surface vehicles, simultaneously monitoring surface targets and lowaltitude unauthorized drones during navigation. For landbased coastal defense robotics, it is compatible with heavyduty wheeled unmanned vehicles and mediumsized quadruped inspection robots, allowing them to penetrate hardtoreach areas such as tidal flats and rocky outcrops for mobile reconnaissance. Upon reaching designated observation positions, the system employs an ultralongfocus telephoto lens to extend visibility far out to sea, thereby filling coverage gaps at fixed surveillance sites. The optical module incorporates intelligent algorithms for boundarycrossing detection, area intrusion, and loitering detection, seamlessly interfacing with the control platform to automatically issue alerts for unauthorized vessels approaching or individuals crossing restricted zones, thus establishing a threedimensional coastal defense network.

Overall, the KC9480M paired with HK100C This electro-optical solution, leveraging ultralongrange optical performance, oceanenvironmentoptimized image processing algorithms, and flexible system scalability, seamlessly supports both fixedsite surveillance and unmanned aerial platform operations. It is tailored to meet the realworld requirements of border and coastal defense projects, providing a mature, domestically developed electrooptical solution for building an intelligent maritime situational awareness system.
