Fisheye Lens – CCL118021MPR

CCL118021MPR Fisheye CCTV HD lens IR corrected 1/1.8″ Φ5.6 M12 lens 180° 8MP F2.2 security surveillance

2.1mm 8MP M12 Fisheye IR Corrected Lens – 180° FOV

This 2.1mm M12 fisheye lens is designed for compact camera systems requiring high-resolution imaging and extremely wide scene coverage. Supporting a 1/1.8″ image format, 8 megapixel resolution, and a 180° field of view in diagonal, horizontal, and vertical directions, the lens enables a single camera to capture a very broad surrounding area. Its 2.1mm focal length and F2.2 fixed aperture provide an effective optical configuration for ultra-wide-angle imaging, while the M12x0.5 mount supports integration into compact embedded camera modules. With an IR-corrected optical design, this 8MP M12 fisheye lens is suitable for imaging systems where wide coverage and consistent optical performance across visible and near-infrared wavelengths are important.

M12 Fisheye Lens Applications & Compatible Devices

High-Resolution Panoramic Monitoring

The combination of 8MP resolution and 180° FOV makes this lens suitable for systems that need both broad scene coverage and higher image detail. A single camera can monitor a large area while providing more pixels for subsequent image analysis.

Compatible devices: panoramic monitoring cameras, wide-area security cameras, ceiling-mounted cameras, high-resolution embedded cameras.

Indoor Wide-Area Security

The 180° viewing angle is useful for monitoring rooms, entrances, retail environments, corridors, and other areas where a conventional narrow-angle lens may leave blind zones. The 0.1m minimum object distance also allows the lens to work in relatively close-range installation environments.

Compatible devices: indoor security cameras, smart home cameras, IoT monitoring devices, compact network cameras.

Robotics and Environmental Awareness

For mobile robots and compact autonomous platforms, an ultra-wide-angle lens can provide a broad view of the surrounding environment. The 8MP resolution adds greater image detail for systems performing visual analysis after image capture.

Compatible devices: mobile robots, service robots, autonomous platforms, embedded vision modules.

See Robotics Vision Solutions for application-specific optical requirements.

Embedded Vision Systems

The M12x0.5 interface and relatively compact 27.9mm TTL make this lens suitable for embedded camera architectures where optical size and field of view are important design considerations.

Compatible devices: embedded camera modules, smart devices, IoT imaging systems, compact vision cameras.

8MP Resolution for Ultra-Wide Imaging

One of the main advantages of this model is the combination of 8MP resolution and 180° FOV. Ultra-wide fisheye lenses traditionally prioritize scene coverage, while higher resolution allows the captured image to retain more usable detail across the large viewing area.

The specified -94% distortion is an inherent characteristic of the fisheye optical configuration. Therefore, this lens should be selected when extremely wide coverage is more important than maintaining straight-line geometry. Applications requiring geometrically corrected images can combine the optical system with suitable digital distortion correction.

For additional information about distortion characteristics, visit the Distortion Guide.

IR Corrected Optical Performance

This model is specified as IR Corrected, making it different from a standard visible-light-only fisheye lens. IR correction can help control wavelength-dependent focus shifts and maintain more consistent image sharpness when the camera system operates across visible and near-infrared wavelengths.

This characteristic can be valuable in smart monitoring and embedded imaging systems that use near-infrared illumination or require stable imaging performance across different wavelengths.

How to Select This 8MP M12 Fisheye Lens

When selecting an ultra-wide M12 lens, the sensor format, image circle, required field of view, resolution, distortion characteristics, mechanical dimensions, and wavelength requirements should be considered together.

This model is best suited to projects where 8MP image detail and 180° scene coverage are both important. The 1/1.8″ format and Φ5.6 image circle should also be matched with the camera sensor before final integration.

Use the Sensor Guide to evaluate sensor compatibility and the FOV Calculator to plan the required viewing coverage.
