Fisheye Lens – S02512812120

S02512812120 is 5-Megapixel High-Performance wide angle fisheye lens 1/2.8″ 2.5mm M12/S-mount lens, F2.0 aperture high resolution CCTV lens.

2.5mm 5MP M12 Fisheye Lens

This 2.5mm 5MP M12 fisheye lens is designed for compact camera systems that require extremely wide scene coverage in a small optical package. With a 161° diagonal FOV, 121° horizontal FOV, F2.0 aperture, and M12×0.5 mount, it is well suited to panoramic monitoring, smart device imaging, and wide-area embedded vision applications.

M12 Fisheye Lens Core Highlights

• 161° Ultra-Wide FOV: Captures a very broad scene from a single compact camera position.
• 5MP High-Resolution Imaging: Provides detailed image output for wide-area monitoring and embedded vision.
• F2.0 Aperture: Supports efficient light collection for compact imaging systems.
• M12×0.5 Mount: Simplifies integration into small camera modules and embedded vision devices.
• Compact Optical Configuration: 4.8mm BFL and 15.29mm TTL support space-constrained camera designs.

The combination of a 2.5mm focal length and 161° diagonal field of view makes this lens particularly useful when maximum scene coverage is more important than rectilinear image geometry. Engineers can use the FOV Calculator to evaluate how the lens will cover a target area with a specific sensor and installation distance.

M12 Fisheye Lens Applications

Core Application Scenes

This 2.5mm M12 fisheye lens is designed for imaging systems that need to observe a large surrounding area from a relatively small camera footprint. Its 121° horizontal FOV can provide extensive lateral coverage, making it suitable for cameras installed in locations where repositioning or multiple cameras would otherwise be required.

For indoor panoramic monitoring, the lens can capture a broad view of rooms, entrances, retail spaces, corridors, and equipment areas. The 5MP resolution provides a useful balance between wide-area coverage and image detail, while the F2.0 aperture supports compact camera designs that need practical light-gathering performance.

The lens is also suitable for smart building and embedded IoT vision, where a small camera module may need to monitor activity across a relatively large area. Its compact M12 interface and short BFL make it easier to incorporate into constrained mechanical assemblies.

Because this is a strong fisheye design, the significant distortion is an inherent characteristic of its extremely wide field of view rather than a low-distortion feature. For projects where image geometry is critical, engineers should evaluate the required distortion level alongside FOV during lens selection.

Compatible Device List

• Panoramic Indoor Cameras: Suitable for room-overview cameras that need to capture a large area from a single installation point.
• Smart Building Cameras: Useful for monitoring entrances, common areas, corridors, and other spaces in smart building systems.
• Retail Vision Devices: The broad FOV can help cover large sections of stores, display areas, and customer zones.
• Embedded IoT Cameras: The M12×0.5 mount supports integration into compact smart camera modules and connected imaging devices.
• Robotics Awareness Cameras: Suitable for robots requiring broad environmental visibility for general visual awareness and obstacle observation.
• Compact Wide-Area Monitoring Systems: The 2.5mm focal length provides extensive scene coverage where camera installation space is limited.

Designed for panoramic indoor monitoring, smart building vision, and compact wide-area imaging applications.

Frequently Asked Questions

Q: What type of lens is this 2.5mm M12 lens?
A: It is a fixed focal length M12 fisheye lens designed to provide extremely wide scene coverage, with a 161° diagonal field of view when used with the specified sensor format.

Q: What is the field of view of this 5MP M12 fisheye lens?
A: The lens provides a 161° diagonal FOV, 121° horizontal FOV, and 91° vertical FOV.

Q: What sensor size is this lens designed for?
A: The specified optical configuration is designed for a 1/2.8″ image format and supports 5MP resolution.

Q: Why does this lens have high distortion?
A: The distortion of less than -69% is associated with its extremely wide 161° diagonal field of view. Strong fisheye designs intentionally prioritize very broad scene coverage over rectilinear image geometry.

Q: Is this a low distortion lens?
A: No. With distortion specified below -69%, this lens should be positioned as a fisheye or ultra-wide-angle lens rather than a low distortion lens.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, making it suitable for applications where the camera needs to observe relatively nearby areas.

Q: Does this M12 lens have optical zoom?
A: No. It uses a fixed 2.5mm focal length and does not provide variable optical zoom.

Q: Is this lens suitable for panoramic monitoring?
A: Yes. Its 161° diagonal FOV and 121° horizontal FOV make it well suited to panoramic and wide-area monitoring applications where broad scene coverage is a primary requirement.
