Pinhole Lens – CCL1216PMP

CCL1216PMP Pinhole lens 16mm 1/2″ HD CCTV M12 mount lens for Covert Surveillance, hidden camera

16mm M12 Pinhole Lens | 28° FOV F1.8 3MP Lens

The 16mm M12 Pinhole Lens is a compact fixed-focus optical solution designed for embedded imaging systems that require controlled scene coverage without the wider perspective of a short focal length lens. With a 16mm focal length and 28° horizontal FOV, this M12 pinhole lens provides a balanced viewing angle for targeted monitoring, embedded inspection and compact camera applications. The F1.8 aperture provides useful light-gathering capability for imaging environments with varying illumination.

Designed for 1/2″ image formats, this 16mm M12 Pinhole Lens uses an M12x0.5 mount with a fixed iris, manual focus and 25.5mm TTL. Its compact configuration makes it suitable for camera modules where limited installation space and a defined viewing area are important. The 0.2m minimum object distance also allows the lens to be used in relatively close-range embedded imaging setups.

M12 Pinhole Lens Core Highlights

• 16mm Focal Length: Provides controlled 28° horizontal coverage for targeted imaging applications.
• 3MP Resolution: Suitable for camera systems requiring more imaging detail than standard 2MP configurations.
• F1.8 Aperture: Provides good light-gathering capability for compact embedded camera systems.
• M12x0.5 Mount: Supports integration into compact camera modules and space-constrained devices.
• 25.5mm TTL: Maintains a compact optical configuration for embedded applications.

Balanced Narrow-FOV Imaging for Embedded Systems

The 16mm focal length gives this M12 Pinhole Lens a useful balance between coverage and target concentration. Its 28° horizontal FOV is narrower than many short-focal-length wide-angle M12 lenses, while still providing more scene coverage than longer focal length pinhole models.

This makes the lens suitable for applications where the camera needs to monitor a defined area without excessively capturing surrounding background. It can be positioned toward a particular entrance, equipment section, inspection area or other predetermined target.

When determining the appropriate focal length, the sensor dimensions, target distance and required viewing area should be evaluated together. TOWIN’s FOV Calculator can help engineers estimate the relationship between focal length, sensor size and field of view.

M12 Pinhole Lens Applications

Embedded Security Monitoring

The 28° horizontal FOV provides a controlled viewing area for compact security devices that need to monitor a specific zone. The lens can be integrated into embedded camera modules for entrances, access points, corridors and other defined monitoring locations.

Access Control Systems

For access-control equipment, the lens can provide a focused view of a designated checkpoint or entry area. Its M12x0.5 interface and compact TTL make it suitable for camera assemblies where installation space is restricted.

Compact Equipment Monitoring

The 16mm focal length can be used to monitor a specific section of machinery or equipment without requiring the camera to capture an unnecessarily wide scene. This makes it suitable for embedded monitoring devices and specialized equipment cameras.

Embedded Inspection Cameras

The 3MP resolution and 28° FOV can support compact inspection systems where the viewing area is predefined. Manual focus allows the installer to optimize the lens for the required working distance during system assembly.

Specialized OEM Camera Modules

The combination of 16mm focal length, F1.8 aperture, 3MP resolution and M12x0.5 mounting makes this lens suitable for custom camera modules and specialized embedded imaging products. It can be integrated into OEM equipment where a compact fixed-focus optical solution is required.

Lens Selection Considerations

The 16mm focal length provides a moderately narrow field of view compared with short focal length M12 lenses. It is therefore suitable when the application requires more controlled scene coverage while retaining a reasonable amount of surrounding information.

When selecting this lens, consider:

• Camera sensor format and active image area
• Required horizontal, vertical and diagonal FOV
• Target distance
• Desired image resolution
• Available illumination
• Installation space
• Mounting interface
• Required focusing method

For additional optical selection guidance, see TOWIN’s Lens Selection Guide.

The Sensor Guide can also help engineers confirm the relationship between sensor format and lens image coverage.
