Pinhole Lens – CCL1230PMP

CCL1230PMP Pinhole lens 1/2″ 30mm HD CCTV M12 mount lens Covert hidden Surveillance high temperature metallurgy

30mm M12 Pinhole Lens

This 30mm M12 pinhole lens is designed for compact camera systems that require a narrow and controlled field of view for targeted observation. Featuring a 30mm fixed focal length, 12° horizontal FOV, 2MP resolution, and a fast F1.6 aperture, the lens is well suited to applications where the camera needs to focus on a specific area rather than capture a wide scene. Its 1/2″ image format and M12×0.5 mount provide compatibility with compact camera modules and embedded imaging devices.

Designed for discreet security monitoring, access control, equipment observation, and compact embedded camera applications, this M12 pinhole lens combines a long focal length with a compact optical configuration. The 0.2m minimum object distance provides flexibility for relatively close-range installations, while the 16.8mm TTL helps support integration into space-constrained camera housings.

M12 Pinhole Lens Core Highlights

• 30mm fixed focal length provides a narrow, targeted viewing angle for focused observation.
• 12° horizontal FOV helps capture a defined scene without unnecessary peripheral coverage.
• F1.6 aperture provides strong light-gathering capability for demanding indoor and low-light environments.
• 2MP resolution support makes the lens suitable for standard megapixel compact camera systems.
• M12×0.5 mount enables straightforward integration with small embedded camera modules.

M12 Pinhole Lens Applications

Discreet Security Monitoring

The combination of a 30mm focal length and 12° horizontal field of view makes this lens suitable for security systems that need to monitor a specific area from a fixed camera position. Instead of covering a large scene, the narrow FOV allows the camera to concentrate on defined zones such as entrances, counters, equipment areas, or restricted access points.

Its pinhole configuration can also support camera designs where the optical opening needs to remain compact and unobtrusive.

Access Control & Entry Monitoring

A narrow field of view can be advantageous for access control systems where the camera is positioned to observe a particular doorway, gate, identification area, or user interaction zone. The 30mm focal length helps limit unnecessary background content and concentrate the image on the intended monitoring area.

The 0.2m minimum object distance also provides flexibility for relatively close installation scenarios.

Equipment & Instrument Monitoring

This M12 pinhole lens can be integrated into compact monitoring systems designed to observe specific equipment, instruments, displays, or control areas. The 12° horizontal FOV is particularly useful when the camera needs to monitor a defined target rather than an entire workspace.

For applications requiring precise optical matching, TOWIN’s Lens Selection Guide provides additional guidance on focal length, sensor size, FOV, and working distance.

Compact Embedded Vision

The M12×0.5 mount and compact optical configuration make this lens suitable for embedded camera systems where installation space is limited. It can be considered for OEM camera modules, compact monitoring devices, intelligent equipment, and other small-form-factor imaging products.

TOWIN provides additional M12 Lens solutions for compact embedded imaging applications.

Targeted Close-Range Observation

With a specified M.O.D. of 0.2m, the lens can be used for applications where the camera needs to observe a defined object or area at relatively short distances. The manual focus configuration allows the optical system to be adjusted according to the actual installation distance and target position.

Compatible Devices

This 30mm M12 pinhole lens can be considered for integration with:

• Compact security camera modules
• Access control camera systems
• Door and entrance monitoring devices
• Embedded monitoring cameras
• Equipment inspection cameras
• Instrument monitoring modules
• Compact OEM camera assemblies
• Targeted observation devices
• Space-constrained vision systems

The final optical configuration should be evaluated according to the selected image sensor, working distance, required image coverage, mechanical structure, and camera housing.

Why Choose a 30mm Pinhole Lens?

Compared with short focal length pinhole lenses, a 30mm configuration provides a much narrower viewing angle. This makes it more appropriate when the application requires targeted imaging rather than wide-area coverage.

The F1.6 aperture is another important characteristic. A relatively fast aperture can help provide more available light to the sensor, which is useful for indoor monitoring and other applications where illumination may be limited.

When selecting the lens, the 12° horizontal FOV should be evaluated against the required target size and camera-to-object distance. TOWIN’s FOV Calculator can help estimate the expected image coverage for a specific sensor and working distance.

Frequently Asked Questions

Q: What type of lens is this product?
A: This 30 mm fixed‑focal M12 pinhole lens serves compact camera systems that demand a narrow, controlled field of view.

Q: What is the field of view of the 30mm M12 pinhole lens?
A: The specified horizontal field of view is 12°. The actual image coverage also depends on the camera sensor dimensions and working distance.

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

Q: Is the aperture fixed?
A: Yes. The lens uses a fixed F1.6 aperture, providing a relatively fast optical configuration for compact camera applications.

Q: Is the focus adjustable?
A: Yes. The lens features manual focus, letting the optical system match target installation distances. The specified minimum object distance is 0.2m.

Q: What mount does this pinhole lens use?
A: The lens adopts an M12×0.5 mount; compact embedded camera modules widely deploy this interface.

Q: Is a 30mm pinhole lens suitable for wide-area monitoring?
A: Generally, no. Its 12° horizontal FOV is relatively narrow and is better suited to targeted observation. For wide-area imaging, a shorter focal length or wide-angle lens would generally be more appropriate.

Q: Can TOWIN customize this M12 pinhole lens?
A: TOWIN can support customized optical solutions based on requirements such as focal length, sensor format, field of view, mechanical dimensions, and application conditions. Contact TOWIN to discuss a specific project.
