Fisheye Lens – CCL123019MP

CCL123019MP Fisheye CCTV HD lens IR corrected 1/2.3″ Φ4.5 M12 lens 185° 9MP F2.2 security surveillance

1.9mm 9MP M12 Fisheye Lens

This 1.9mm 9MP M12 fisheye lens is designed for compact imaging systems that require an extremely wide 185° field of view. With a 1/2.3″ image format, 9MP resolution, F2.2 fixed aperture, and IR-corrected optical design, it provides broad scene coverage for panoramic, surveillance, embedded vision, and smart camera applications. The M12x0.5 mount and lightweight 9g construction make this M12 fisheye lens suitable for space-constrained camera modules where wide-area imaging and compact integration are important.

M12 Fisheye Lens Core Highlights

• 185° ultra-wide field of view — Captures an exceptionally broad scene with 185° diagonal, horizontal, and vertical FOV.
• 9MP high-resolution imaging — Supports detailed image capture while maintaining extremely wide scene coverage.
• 1.9mm M12 fisheye design — Combines a very short focal length with a compact M12x0.5 mounting interface.
• IR-corrected optics — Helps maintain consistent imaging performance across visible and infrared wavelengths.
• Compact and lightweight construction — Only 9g, making it suitable for embedded cameras and compact vision devices.

M12 Fisheye Lens Applications & Compatible Devices

Panoramic and Wide-Area Monitoring

The 185° FOV makes this lens particularly suitable for cameras that need to observe a very large area from a single installation point. It can be used in panoramic monitoring cameras, compact surveillance modules, indoor security cameras, and smart monitoring devices where maximizing scene coverage is more important than maintaining a rectilinear image.

For applications requiring broader optical coverage, this lens can also complement TOWIN’s Fisheye Lenses portfolio.

Smart Security Cameras

The combination of 9MP resolution and 185° FOV allows a single compact camera module to monitor a large area. This makes the lens suitable for smart security cameras, room monitoring systems, entrance monitoring, retail monitoring, and embedded surveillance equipment.

The 0.1m minimum object distance also supports relatively close-range scene capture, making it useful for compact indoor monitoring devices where the camera may be installed close to the monitored area.

Embedded and IoT Vision Devices

With a 9g construction, 35.2mm TTL, and M12x0.5 mount, this lens is well suited to compact embedded vision designs. Potential devices include smart home cameras, IoT cameras, compact panoramic modules, robotics vision modules, and other space-constrained imaging equipment.

Panoramic Robotics and Mobile Vision

The extremely wide FOV can help mobile or robotic devices observe a large surrounding area with a single camera. This can be useful for navigation support, environmental awareness, obstacle observation, and compact robotic vision modules where reducing blind spots is a priority.

The 185° optical coverage should be considered together with the application’s image-processing requirements, particularly where fisheye image correction or panoramic stitching is required.

Compatible Devices

This 1.9mm 9MP M12 fisheye lens can be considered for:

• Panoramic cameras
• Smart security cameras
• Indoor monitoring cameras
• IoT vision devices
• Embedded camera modules
• Compact robotic cameras
• Wide-area observation systems
• Panoramic imaging modules

Designed for panoramic and wide-area monitoring applications, this lens combines ultra-wide optical coverage, high resolution, compact construction, and IR correction in a small M12 form factor.

Optical Selection Considerations

Because the lens provides a 185° field of view, it is fundamentally different from conventional rectilinear wide-angle lenses. The F-Theta distortion of < -23% is part of the optical design required to achieve this extremely wide coverage and should not be interpreted as a low-distortion specification.

When selecting this lens for a camera system, designers should verify the sensor format, required image-processing pipeline, mounting space, and whether fisheye correction is required. TOWIN’s Lens Selection Guide can help engineers evaluate focal length, sensor compatibility, FOV, and other optical requirements.

For applications where field-of-view calculations are required, the FOV Calculator can also be used during the lens selection process.
