In demanding professional scenarios such as dynamic border and coastal surveillance, large-scale forest fire prevention, vehicle-mounted mobile forensics, judicial trial recording, and remote broadcasting of large-scale events, visual acquisition devices have long been confronted with two core limitations: loss of fine details in long-distance observations and failure to produce clear images in complex lighting conditions. Traditional integrated camera modules either have limited zoom capabilities, making it impossible to verify the identity of distant targets; or they rely on simplistic night-vision algorithms, resulting in excessive noise in scenes during dawn and dusk, rainy nights, or backlit conditions—thus failing to meet the stringent requirements for law enforcement evidence collection and routine unattended operation.

As a professional supplier of core components for visual imaging, Kaimorui, leveraging years of experience in optical lens calibration and image algorithm development, has launched the CM8240KB 40x integrated high-definition zoom module. The product features...40 Pure optical lossless zoomandICR automatic day/night switching paired with multi-level composite noise reduction featuring 2D+3D enhancements.As two core, robust pillars, combined with a full suite of sophisticated image tuning capabilities and industrial-grade reliable hardware design, this solution thoroughly addresses two major industry pain points: long-distance observation and all-weather operation in low-light conditions. It provides system integrators and OEMs with a high-performance vision kernel that can be rapidly embedded and integrated, enabling stable, clear, and traceable video capture even in demanding outdoor and indoor professional environments.

I. 40x native optical lossless zoom—achieve panoramic sweeps and precise long-range analysis with just one lens.

The core contradiction in large-scale security monitoring lies between wide-angle, all-round coverage and long-focus, detail capture.You can't have it all—relying solely on digital zoom to blur the edges of an image and create fragmented outlines simply won't meet the evidentiary requirements for identifying border and coastal defense personnel, pinpointing fire sources in forested areas, or capturing license plates on roads. The Kaimor CM8240KB is equipped with a professional day-and-night lens featuring a long focal length ranging from 4.25mm to 170mm, offering a physical optical zoom ratio of up to 40x. At the wide-angle end, its 66.35° field of view enables rapid, comprehensive scans of entire coastlines, mountainous regions, and factory perimeters. At the telephoto end, its narrow 1.90° field of view allows precise magnification and detailed verification of suspicious targets located several kilometers away.

The lens features an F1.6 large-aperture light-transmitting design, ensuring sufficient light intake throughout the entire zoom range. Paired with intelligent one-touch ultra-fast autofocus, it can instantly lock onto subjects ranging from as close as 0.1 meters in macro mode to as far away as 10 kilometers in ultra-long-distance mode. The zoom speed is adjustable in 0–7 levels, allowing users to customize settings according to their needs. Additionally, up to five key cruising positions can be pre-set, enabling border guard posts, high-risk forest areas, and critical waterways to quickly call up and execute preset cruising routines with a single touch. When combined with 32x digital zoom, the overall maximum magnification reaches up to 1,280x, clearly capturing distant subjects such as facial features of individuals, ship markings, vehicle license plates, and even minute damage on equipment. This pure optical zoom eliminates any image quality degradation or compression artifacts, completely sidestepping issues like trailing and blurring commonly associated with digital zooming. In practical applications, this mechanism can be integrated into border defense optoelectronic pan-tilt platforms for round-the-clock coastal surveillance; embedded in mobile law enforcement terminals for long-distance evidence collection during mobile patrols; used in large-scale events to replace multiple camera positions with a single device for live broadcasting; or deployed in high-altitude observation towers for early warning of forest fires. A single mechanism can effectively substitute multiple fixed-camera setups, significantly reducing overall project installation and maintenance costs.

II. ICR automatic day/night switching + 2D & 3D hybrid noise reduction, delivering pure image output even in low-light and complex lighting conditions.

The greatest challenge in 24-hour outdoor surveillance lies in the dramatic fluctuations of light: intense daylight with backlighting, low illumination during twilight, and complete darkness at night without any auxiliary light sources—all of which can easily lead to overexposure, excessive noise in dark areas, and motion blur or trailing on moving objects. The CM8240KB is equipped with the Sony STARVIS IMX462LQR-C starlight-grade image sensor, paired with a mechanical ICR infrared filter that enables automatic day-and-night switching, along with a dual-layer noise reduction algorithm—combining 2D static and 3D dynamic processing—to create a comprehensive, low-noise imaging system capable of delivering high-quality images around the clock.

ICR can automatically switch between color and black-and-white modes based on ambient illumination thresholds. During the day, it filters out infrared interference to restore true colors; at night, it switches to enhanced black-and-white night vision with infrared illumination. In color mode, the minimum illumination level is 0.01 Lux. With DSS digital slow shutter enabled, the minimum illumination can be as low as 0.001 Lux. In black-and-white night vision mode, sensitivity reaches as low as 0.0002 Lux, enabling effective imaging in environments such as unlit barren hills, rainy nights along coastlines, and underground tunnels—without the need for additional infrared illuminators. The 2D noise reduction algorithm eliminates graininess and speckles from static scenes like skies and walls, while the 3D temporal noise reduction effectively suppresses motion blur caused by dynamic elements such as swaying branches, moving vehicles, and ocean waves. The noise reduction intensity is finely adjustable across 16 levels, striking a balance between image clarity and preservation of critical details, without over-smoothing that might obscure target outlines. Meanwhile, built-in wide dynamic range, strong-light suppression, and backlight compensation features enable the camera to handle extreme lighting conditions—including glare from sea surfaces, backlighting in forests, and direct sunlight from vehicle headlights at intersections—with ease. With a signal-to-noise ratio exceeding 50 dB, the camera delivers clean, crystal-clear images, making it ideally suited for high-demand applications such as nighttime border surveillance, 24-hour perimeter security monitoring in industrial parks, and remote video recording for nighttime court proceedings—achieving truly seamless, reliable, and continuous day-and-night monitoring.

III. Full-dimensional intelligent image tuning, compatible with multiple protocols and adaptable to various integration solutions.

In addition to its two core imaging capabilities, the CM8240KB is equipped with a comprehensive, professional-grade image parameter adjustment system that allows for targeted image quality optimization tailored to various industry-specific scenarios. The exposure mode offers four adjustable options: automatic, aperture-priority, shutter-priority, and manual. The shutter speed range spans from 1 second to 1/30,000 second, and the AGC gain is adjustable across 10 levels. White balance supports both automatic and manual fine-tuning, effectively correcting color deviations caused by special light sources such as industrial and mining lighting or high-color-temperature lights near the sea. Additional features include customizable contrast, sharpness, and gamma curves, as well as practical functions like image mirroring and flipping, 8-zone privacy masking, 4-zone motion detection alarms, DIS electronic image stabilization, and automatic bad-pixel correction. This camera demonstrates exceptional stability even during prolonged, uninterrupted operation. The signal output supports both LVDS digital signals and CVBS analog signals simultaneously, ensuring compatibility with both PAL and NTSC standards. At the protocol level, it comes standard with the widely used Pelco-P/D and VISCA control protocols; device addresses can be freely set from 1 to 255, and multiple baud rates can be flexibly configured. This enables seamless integration with pan-tilt controllers, backend decoding platforms, and live-streaming encoders, making integration extremely straightforward and highly compatible with most existing security and vision system upgrade projects.
