The optical lens features a professional 36x optical zoom mechanism, covering focal lengths from 6.9mm to 249mm, with a horizontal field of view ranging from a wide-angle 56.1° down to a telephoto 1.5°. The zoom response time across the entire range is as low as 4.8 seconds, ensuring smooth and seamless zoom transitions without any image interruptions. The hardware-based night-vision architecture incorporates an ICR automatic infrared filter switch, delivering a minimum color sensitivity of 0.005 Lux and reaching 0.0005 Lux in black-and-white mode. Even in completely dark environments without any artificial lighting, it can still produce pristine, noise-free 4K footage. The camera body includes a built-in hardware-level gyroscope for image stabilization, combined with advanced image-processing algorithms such as 120dB ultra-wide dynamic range, 3D digital noise reduction, electronic defogging, and strong-light suppression. As a result, under challenging conditions—including backlight from car headlights, rainy or foggy weather, gimbal vibrations, and high-altitude winds—the 4K footage remains consistently balanced in color, sharply defined in contours, and rock-steady without any jitter or shaking, ensuring uniform imaging quality around the clock. The camera measures 65×71×149mm, weighs just 420g, and consumes 5W in static mode and 7W during operation. Its lightweight, low-power design makes it suitable for various installation configurations, including gimbals, airborne systems, and embedded installations. It operates reliably within a temperature range of -10℃ to 60℃ and can function stably in environments with up to 90% relative humidity, demonstrating exceptional outdoor weather resistance.

II. Built-in deep-learning AI computing power enables 4K high-definition images to have autonomous analysis capabilities.

Unlike conventional 4K camera modules that merely capture video, the KC9436M features a built-in independent AI computing unit. All intelligent analytics are performed directly on the native 4K video stream, ensuring no image quality compression and significantly higher recognition accuracy. The facial capture module can simultaneously capture up to five facial images in a single shot, leveraging its 8-megapixel 4K resolution to preserve complete facial features, facilitating post-event personnel tracing and identity verification at entrances and exits. When switched to traffic mode, the device can accurately distinguish between motor vehicles, non-motorized vehicles, and pedestrians, automatically triggering alerts for violations such as speeding, driving against traffic, and lane occupation. The device comes standard with over ten security detection rules, including area intrusion, boundary crossing, loitering and lingering, object left or taken, camera obstruction, and abnormal audio sounds. A single camera module can cover diverse scenarios, such as perimeter fencing around industrial parks, high-security warehouse areas, riverbank perimeters, and major urban thoroughfares. The device employs the H.265 efficient compression format, dramatically reducing bandwidth usage for 4K video while allowing flexible adjustment of bitrates within the range of 32 Kbps to 16,384 Kbps. It supports simultaneous output of three video streams and multi-channel real-time preview, comes equipped with eight customizable privacy zones, and offers multiple electronic shutter speeds (ranging from 1/1 to 1/30,000 seconds), balancing regulatory requirements with information compliance. The device boasts a comprehensive array of expansion interfaces, including a 100-Mbps network port, audio/video inputs, alarm I/O ports, and RS485/232 communication ports. It supports local video storage via Micro SD cards up to 256 GB, is compatible with ONVIF protocols, mainstream platform SDKs, and cloud access protocols, enabling seamless integration with users’ existing security systems and smooth compatibility with both new and legacy devices—no need for full system replacement.

III. The CM2004M encoding control board seamlessly supports 4K signal switching and overall system scheduling.

The CM2004M is a dedicated MIPI-encoded control board designed specifically for 4K all-in-one camera modules such as the KC9436M. This complete solution ensures precise matching between the camera module and the driver board, eliminating signal conversion losses at the source. The board natively supports SONY FCB series and KEMAO RUI CM fully digital HD/4K camera modules. It features dual signal inputs—LVDS and HDMI—and the HDMI port can stably handle up to 3840×2160@30Hz 4K high-definition video input without any loss or ghosting throughout the entire signal conversion process, with zero color deviation. This guarantees that the full 4K image captured by the front-end device is seamlessly transmitted to the back-end equipment. The control protocol is fully compatible with industry-standard protocols such as SONY VISCA and PELCO-P/D, supporting RS485, serial port pass-through, and multi-channel IO control. Remotely, it can precisely send commands for zoom adjustment, focus control, pan-tilt movement, mode switching, and other functions, enabling seamless integration and compatibility with PTZ cameras, heavy-duty pan-tilt units, and portable surveillance terminals. The board itself measures only 45mm×45mm, featuring a compact square PCB layout with standard positioning mounting holes pre-installed. It has no unnecessary redundant structures, making it plug-and-play and requiring no additional tuning or accessories. This significantly reduces equipment integration time and project construction costs, allowing even small-sized device housings to be easily embedded and assembled.

IV. Integrated software-hardware adaptation for large-scale deployment of 4K security surveillance projects across all scenarios.

When paired with the CM2004M, the KC9436M enables rapid integration via ultra-fine coaxial cables, resulting in neat and streamlined cabling that is ideal for large-scale security projects involving thousands of camera points and allowing for efficient mass deployment. The entire system is equipped with a multi-layered security protection framework, featuring tiered user permissions, MAC address binding, HTTPS encryption, and 802.1x network authentication—all providing layered defense. Video data at 4K resolution and device control commands are fully encrypted throughout the entire process, meeting the stringent security standards required by high-security industries such as public security, finance, and military manufacturing. This complete system combination covers a wide range of real-world applications: In smart transportation systems, road checkpoints rely on a 36x telephoto lens combined with 4K HD cameras to precisely capture license plates and vehicle models; in safe cities, wide-angle lenses paired with AI-powered detection technologies strengthen urban security defenses; in industrial parks and logistics warehouses, low-power, weather-resistant cameras enable 24-hour unattended surveillance; and in commercial complexes and cultural venues, privacy-shielding features coupled with facial recognition capabilities ensure customer flow management while maintaining compliance with privacy regulations. In the wave of ultra-high-definition security upgrades, solutions composed of discrete components often suffer from inconsistent stability. As a result, pre-configured, matched module sets have become the industry’s preferred approach. The Kaimorui KC9436M handles 4K imaging and AI-powered intelligent analysis, while the CM2004M takes charge of signal conversion and overall system control and scheduling. These two products feature deeply optimized hardware specifications and coordinated operational logic, effectively eliminating compatibility issues, reducing debugging complexity, and extending equipment lifespan. Kaimorui continues to focus on building a comprehensive ecosystem around 4K camera modules, offering standardized, high-performance hardware solutions that empower various industries to establish stable, intelligent, and long-lasting ultra-high-definition security systems.
