Pinhole Lens – CCL1215PMP

CCL1215PMP Pinhole lens 10mm 1/3″ 28° HD CCTV M12 mount lens for Covert Surveillance, hidden camera

15mm M12 Pinhole Lens

This 15mm M12 pinhole lens is designed for compact camera systems that require controlled image coverage in a discreet optical configuration. Featuring a 15mm fixed focal length, 28° horizontal field of view, 2MP resolution, and a fast F1.6 aperture, the lens provides a balanced solution between wide-area coverage and targeted observation. Its 1/3″ image format and M12×0.5 mount make it suitable for compact embedded camera modules and space-constrained imaging equipment.

Designed for discreet security monitoring, access control, equipment observation, and compact embedded vision applications, this fixed focal pinhole lens provides a controlled viewing angle while maintaining a compact mechanical configuration. The 0.2m minimum object distance supports relatively close-range installations, while the 22.32mm TTL provides a defined optical length for integration into compatible camera housings.

Product Core Highlights

• 15mm fixed focal length provides controlled image coverage for targeted observation.
• 28° horizontal FOV offers a focused viewing range without the extreme narrowness of longer focal length pinhole lenses.
• F1.6 aperture provides strong light-gathering capability for indoor and relatively low-light applications.
• 2MP resolution supports compact megapixel camera systems.
• M12×0.5 mount and 22.32mm TTL support integration into compact embedded camera assemblies.

M12 Pinhole Lens Applications

Discreet Security Monitoring

The 28° horizontal field of view makes this 15mm M12 pinhole lens suitable for monitoring a defined area while maintaining more controlled scene coverage than short focal length lenses. It can be used in compact security camera modules positioned toward entrances, corridors, counters, equipment zones, or other specific monitoring areas.

The pinhole optical configuration is particularly useful when the camera design requires a compact and unobtrusive lens opening.

Access Control & Entrance Monitoring

This lens can be considered for access control terminals and entrance monitoring devices where the camera needs to focus on a designated interaction area. The 15mm focal length provides a more concentrated view than short focal length M12 lenses, while the 28° horizontal FOV retains useful scene coverage around the target.

The manual focus design allows adjustment according to the actual installation distance, with a specified minimum object distance of 0.2m.

Embedded Camera Modules

The M12×0.5 mount and 22.32mm TTL make the lens suitable for compact camera assemblies where mechanical dimensions are an important consideration. It can be integrated into embedded monitoring devices, OEM camera modules, access equipment, and other small-form-factor imaging systems.

For additional compact optical solutions, see TOWIN’s M12 Lens solutions.

Equipment Monitoring

The controlled field of view makes this pinhole lens suitable for monitoring specific equipment, instruments, displays, control panels, or designated machine areas. Rather than capturing an unnecessarily broad scene, the camera can be positioned to concentrate on the intended observation zone.

This configuration can be useful in environments where the camera must monitor a specific object or operating area within a larger workspace.

Indoor Targeted Imaging

With an F1.6 aperture and 28° horizontal FOV, the lens can be considered for indoor applications requiring focused imaging under controlled or variable illumination. Potential uses include equipment monitoring, compact inspection devices, access points, and localized observation systems.

For projects requiring precise optical matching, TOWIN’s Lens Selection Guide can help engineers evaluate focal length, sensor size, FOV, and working distance.

Compatible Devices

This 15mm M12 pinhole lens can be considered for integration with:

• Compact security camera modules
• Access control camera systems
• Entrance monitoring devices
• Embedded camera modules
• Equipment monitoring cameras
• Instrument observation systems
• Compact OEM camera assemblies
• Control panel monitoring devices
• Small-form-factor vision systems
• Discreet embedded imaging devices

The final optical configuration should be evaluated according to the sensor dimensions, target size, working distance, image coverage, mechanical clearance, and camera housing.

Why Choose a 15mm Pinhole Lens?

The 15mm focal length and 28° horizontal FOV place this lens between short focal length and long focal length pinhole configurations. It provides more targeted coverage than a wide-view lens while avoiding the extremely narrow viewing angle of 30mm or 45mm configurations.

The F1.6 aperture is another important feature for compact imaging systems. Its relatively fast aperture can provide useful light-gathering capability when the camera operates under indoor or limited-light conditions.

When selecting the lens, the 28° FOV should be evaluated together with the camera sensor and installation distance. TOWIN’s FOV Calculator can help estimate the expected image coverage for a specific camera configuration.

Frequently Asked Questions

Q: What type of lens is this product?
A: This product is a 15mm fixed focal M12 pinhole lens designed for compact camera systems requiring controlled and targeted image coverage.

Q: What is the field of view of the 15mm M12 pinhole lens?
A: The specified horizontal field of view is 28°. Actual image coverage depends on the sensor dimensions and camera-to-target distance.

Q: What sensor size is this lens designed for?
A: The lens is specified for a 1/3″ image format and supports 2MP resolution according to the supplied product specifications.

Q: Is the aperture fixed?
A: Yes. The lens uses a fixed F1.6 aperture.

Q: Does this pinhole lens support manual focus?
A: Yes. The lens uses manual focus and has a specified minimum object distance of 0.2m, allowing the focus to be adjusted for the intended installation distance.

Q: What mount does this lens use?
A: This pinhole lens uses an M12×0.5 mount, making it suitable for compatible compact camera modules.

Q: Is a 15mm pinhole lens suitable for wide-area surveillance?
