Wide Angle Lens – S02812713120

S02812713120 is 2.8mm high resolution M12 Wide Angle Lens with Built-In Filter, 1/2.7″ M12/S-mount lens, F2.0 aperture 8-Megapixel CCTV lens.

2.8mm 8MP M12 Wide Angle Lens

This 2.8mm 8MP M12 M12 Wide Angle Lens is designed for compact imaging systems that require high-resolution imaging with an exceptionally wide field of view. Supporting 158° diagonal FOV on a 1/2.7″ sensor, 131° horizontal coverage, and an M12×0.5 mount, it is well suited for panoramic surveillance, embedded AI vision, robotics awareness, and other space-constrained wide-angle imaging applications.

M12 Wide Angle Lens Core Highlights

• 158° Ultra-Wide FOV: Captures an exceptionally broad scene with 131° horizontal coverage on a 1/2.7″ sensor.
• 8MP High Resolution: Provides detailed imaging for demanding compact vision and surveillance applications.
• 2.8mm Fixed Focal Length: Delivers extensive scene coverage from a compact fixed-focus optical configuration.
• M12×0.5 Mount: Supports integration into compact embedded camera modules and small-form-factor imaging devices.
• Multi-Sensor Compatibility: Provides specified FOV performance for both 1/2.7″ and 1/2.8″ sensor formats.

The combination of 8MP resolution and ultra-wide-angle coverage makes this lens particularly suitable when a camera needs to capture a large surrounding area from a compact installation point. For engineers evaluating coverage requirements, the FOV Calculator can help compare focal length, sensor format, and field of view.

M12 Wide Angle Lens Applications

Core Application Scenes

This 2.8mm M12 M12 Wide Angle Lens is designed for applications where maximizing scene coverage is a priority. Its 158° diagonal field of view on a 1/2.7″ sensor allows a compact camera to observe a very broad area without requiring a mechanically moving camera head.

For indoor panoramic security, the lens can be integrated into compact cameras positioned on ceilings, walls, entrances, corridors, retail areas, or other locations where minimizing blind zones is important. The 8MP optical specification also provides additional image detail for wide-area monitoring and scene analysis.

The lens is also suitable for robotics and embedded AI vision, where a broad visual field can help a device detect surrounding objects, people, or obstacles. Its M12×0.5 mounting format makes it practical for compact camera boards and embedded vision modules where installation space is limited.

Because this optical design has significant wide-angle distortion, it is better suited to scene awareness, panoramic coverage, and object detection than precision measurement or applications requiring geometrically accurate image reproduction. Engineers can refer to the Distortion Guide when evaluating whether this optical characteristic matches their application.

Compatible Device List

• Panoramic Security Cameras: Suitable for compact cameras requiring very broad room or area coverage from a single imaging module.
• Smart Home & IoT Cameras: The ultra-wide FOV allows small devices to capture a larger portion of an indoor environment.
• Robotics Vision Modules: Suitable for mobile robots and autonomous devices requiring broad environmental awareness around the camera.
• Embedded AI Cameras: Compatible with compact vision modules used for people detection, object recognition, and scene analysis.
• Retail Monitoring Systems: Useful for overhead or strategically positioned cameras covering wide retail spaces, entrances, and customer areas.
• Compact Panoramic Imaging Devices: The 2.8mm focal length provides broad scene coverage where installation space and camera size are constrained.

Designed for ultra-wide panoramic surveillance, embedded AI vision, and robotics visual awareness applications.

Frequently Asked Questions

Q: What type of lens is this 2.8mm M12 lens?
A: It is a fixed focal length M12 ultra-wide-angle lens with fisheye-level field of view and 8MP resolution.

Q: What is the field of view of this 8MP M12 lens?
A: On a 1/2.7″ sensor, the lens provides 158° diagonal FOV, 131° horizontal FOV, and 70° vertical FOV. On a 1/2.8″ sensor, it provides 153° diagonal, 128° horizontal, and 70° vertical FOV.

Q: Is this lens compatible with both 1/2.7″ and 1/2.8″ sensors?
A: Yes. The specifications provide separate FOV values for both 1/2.7″ and 1/2.8″ sensor formats, allowing engineers to evaluate the optical coverage for either configuration.

Q: Is this a low distortion lens?
A: No. The specified TV distortion is below -36%, which reflects its strong ultra-wide-angle optical design. It should not be positioned as a low distortion lens for precision measurement applications.

Q: Does this lens have an IR cut filter?
A: No. The specification states Without IRCF, meaning this version does not include an integrated IR-cut filter.

Q: Is this lens IR corrected?
A: The available specification does not indicate IR-corrected optical performance. Since the lens is specified as without IRCF, it should not be marketed as an IR corrected lens without additional optical test data.

Q: What applications are suitable for this 2.8mm M12 Wide Angle lens?
A: It is suitable for panoramic surveillance, smart home cameras, embedded AI vision, robotics visual awareness, retail monitoring, and other applications requiring very broad scene coverage.

Q: How can I calculate the actual coverage of this lens?
A: The actual scene coverage depends on sensor dimensions, focal length, and installation distance. The FOV Calculator can help estimate the expected field of view and coverage.

Optical Selection & Related Resources

Ultra-wide-angle lenses require careful evaluation of field of view, sensor format, image circle, distortion, and installation distance. While a wider FOV can significantly reduce blind areas, strong geometric distortion may make the lens less suitable for precision measurement or applications requiring highly accurate image geometry.
