2.9mm 5MP M12 Ultra-Wide Angle Lens for Compact Vision Systems

This 2.9mm 5MP M12 ultra-wide angle lens is designed for compact imaging systems requiring broad scene coverage and high-resolution image capture. With a 140° diagonal FOV, F1.8 aperture, and 1/2.8-inch image format, it provides a strong balance between wide-angle coverage and 5MP imaging performance.

Featuring an M12×0.5 mount, fixed iris, 0.2m minimum object distance, and 3.72mm minimum back focal length, this lens is suitable for compact security cameras, embedded vision devices, smart monitoring equipment, IoT imaging systems, and other applications where a wide viewing area is required within a limited installation space.

M12 Wide Angle Lens Core Highlights

1. 140° Ultra-Wide Field of View

The 2.9mm focal length delivers a 140° diagonal FOV, 107° horizontal FOV, and 77° vertical FOV on a 1/2.8-inch sensor. This allows the camera to capture a broad scene without requiring a large physical installation distance.

2. 5MP High-Resolution Imaging

With 5MP resolution support, this M12 lens is designed for applications that need both wide scene coverage and useful image detail. It can capture people, objects, entrances, equipment, and other visual targets across a relatively large viewing area.

3. F1.8 Aperture for Efficient Light Collection

The F1.8 aperture provides strong light-gathering capability for a compact wide-angle lens. It can help maintain practical image brightness in indoor environments and other scenes with moderate lighting conditions.

4. Close-Range Imaging with 0.2m M.O.D.

A minimum object distance of 0.2m makes the lens suitable for relatively close installation scenarios. This can be useful for compact monitoring equipment, access terminals, indoor devices, and embedded vision systems where the camera may be positioned close to the target.

5. Compact M12×0.5 Mount

The M12×0.5 interface is widely used for compact camera modules. Combined with the short 3.72mm minimum back focal length, the optical configuration can be integrated into space-constrained imaging equipment.

M12 Wide Angle Lens Applications

Compact Security Monitoring

The 140° diagonal field of view allows one camera to cover a broad indoor area, making this lens suitable for entrances, corridors, rooms, retail spaces, and other compact monitoring environments.

Designed for smart security applications where broad coverage and 5MP image resolution are required from a small camera module.

Embedded Vision Systems

The compact M12×0.5 mount makes the lens suitable for embedded cameras integrated into smart devices, IoT equipment, access terminals, and intelligent monitoring systems.

The combination of 2.9mm focal length and 140° FOV is particularly useful when the camera needs to observe a large area while remaining physically compact.

Indoor Scene Awareness

The wide field of view can support people detection, object presence detection, occupancy awareness, and general scene monitoring. The lens is better suited to coverage-oriented imaging than precision measurement because the specified TV distortion is below -15%.

Short-Distance Imaging

With a 0.2m M.O.D., the lens can be used in applications where the camera is installed relatively close to the monitored object. This makes it practical for equipment monitoring, indoor terminals, compact inspection zones, and interactive devices.

Compatible Devices

• 1/2.8″ camera modules
• 5MP security cameras
• M12 embedded cameras
• Smart home cameras
• IoT vision devices
• Access control cameras
• Indoor monitoring cameras
• Compact AI vision devices
• Embedded visual sensing equipment
• Wide-angle monitoring modules

Wide-Angle Imaging vs. Low-Distortion Imaging

A 140° diagonal FOV allows this lens to capture a substantially larger scene than conventional narrow-angle lenses. However, the specified TV distortion is below -15%, so some geometric deformation should be expected toward the image edges.

This characteristic is acceptable for applications such as surveillance, scene awareness, people detection, and object monitoring, where wide coverage is more important than geometric accuracy.

For applications requiring accurate dimensional measurement or straight-line preservation, engineers should consider a dedicated Low Distortion Lens.

Frequently Asked Questions

Q: Is this 2.9mm lens a fisheye lens?
A: No. The lens has a 140° diagonal FOV, which provides ultra-wide coverage but does not meet TOWIN’s practical fisheye classification threshold of approximately 180° or more. It is better classified as an ultra-wide angle M12 lens.

Q: What sensor size is this lens designed for?
A: The specified image format is 1/2.8″, making it suitable for camera modules using a 1/2.8-inch image sensor.

Q: What is the FOV of this 2.9mm M12 lens?
A: The lens provides a 140° diagonal FOV, 107° horizontal FOV, and 77° vertical FOV according to the supplied specifications.

Q: Is this lens suitable for 5MP cameras?
A: Yes. The lens is specified for 5MP resolution and is designed for compact imaging systems requiring high-resolution wide-angle image capture.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.2m, allowing the lens to be used for relatively close-range imaging applications.

Q: Is this an IR-corrected lens?
A: No IR-correction specification is provided for this product. The optical structure is listed as 2G4P, so it should not be marketed as an IR-corrected lens unless additional optical testing confirms IR correction.

Q: Is this lens suitable for precision machine vision measurement?
A: It is not the preferred choice for precision measurement because its specified TV distortion is below -15%. It is better suited to wide-area imaging, monitoring, detection, and scene-awareness applications.

Q: What is the advantage of the F1.8 aperture?
A: The F1.8 aperture provides relatively strong light-gathering capability, helping the camera maintain useful image brightness in indoor and moderate-light environments.
