Pinhole Lens – CCL13028PMP3

CCL13028PMP3 Pinhole lens 2.8mm 13 IR MP HD CCTV M12 mount lens for Covert hidden Surveillance

2.8mm 3MP M12 Pinhole Lens

The 2.8mm 3MP M12 pinhole lens is a compact wide-angle optical solution for camera modules that need to capture a broad scene through a discreet lens configuration. Designed for 1/3″ image sensors, it delivers a 115° diagonal field of view with a 2.8mm fixed focal length, allowing a relatively large area to be captured from a short installation distance. The F2.4 fixed aperture, M12×0.5 mount, and 12mm TTL make the lens well suited to compact camera assemblies where both viewing coverage and mechanical size are important.

Designed for embedded security, indoor monitoring, access-area observation, and compact vision devices, this lens combines 3MP imaging capability with a short optical package. Its 0.2m minimum object distance makes it particularly practical for applications where the camera is positioned close to the monitored scene.

M12 Pinhole Lens Core Highlights

• 3MP optical performance supports compact camera systems using compatible 1/3″ sensors.
• 115° diagonal FOV provides broad scene coverage from a short 2.8mm focal length.
• 12mm TTL helps accommodate space-limited camera and device designs.
• F2.4 fixed aperture provides a practical optical configuration for embedded imaging.
• M12×0.5 interface enables integration with a wide range of compact camera modules.

M12 Pinhole Lens Applications

Embedded Security Modules

This lens is a good fit for compact security devices where the camera needs to cover a relatively broad area without using a large optical assembly. The 115° diagonal field of view can help capture surrounding activity in locations such as small entrances, service areas, counters, and indoor access points.

Its 12mm TTL is also useful when the optical assembly has limited internal space.

Indoor Area Observation

The combination of a 2.8mm focal length and 115° diagonal FOV makes this lens particularly suitable for short-distance indoor observation. Instead of concentrating on a distant target, the optical design allows a compact camera to monitor a larger nearby area.

Potential installations include small rooms, equipment compartments, reception areas, kiosks, and localized monitoring zones.

Access & Interaction Monitoring

Compact terminals often need to capture both the user interaction area and its immediate surroundings. The wide viewing angle of this lens can help reduce blind areas when the camera is mounted relatively close to the subject.

The 0.2m M.O.D. is also relevant to close-position installations where the monitored subject is not far from the camera.

Compact OEM Camera Devices

The combination of a 3MP image format, M12×0.5 mount, 12mm TTL, and 2.8mm focal length provides a practical starting point for OEM camera designs.

The lens can be considered for:

• Embedded monitoring modules
• Compact smart devices
• Small security terminals
• Access monitoring equipment
• OEM camera assemblies
• Space-constrained vision products

Wide-Scene Equipment Monitoring

Some equipment-monitoring systems need to observe the surrounding operating area rather than inspect a single small feature. The 115° diagonal FOV allows this lens to cover a broader nearby scene, making it suitable for monitoring equipment surroundings, operator interaction zones, and compact work areas.

For applications requiring more advanced optical performance, TOWIN’s Machine Vision solutions provide additional lens options.

What Makes This Lens Different from Longer Focal Length Pinhole Lenses?

Focal length has a direct effect on the scene captured by a camera. At 2.8mm, this lens is designed to provide substantially broader coverage than longer focal length pinhole configurations.

That makes it more appropriate for situations where the camera is positioned relatively close to the monitored area and needs to capture its surroundings. A longer focal length, by comparison, is generally more appropriate when the application requires a concentrated view of a particular target.

For a deeper understanding of focal length and optical selection, refer to TOWIN’s Lens Basics.

Field of View Considerations

This model provides a specified 115° diagonal field of view. Such a wide viewing angle can be advantageous when the installation position is constrained and the camera needs to cover a larger nearby scene.

However, FOV should always be evaluated together with sensor size and working distance. A lens that provides sufficient angular coverage may still produce an unsuitable image area if the camera is installed too close or too far from the target.

Use TOWIN’s FOV Calculator to estimate the expected coverage before finalizing the optical configuration.
