Pinhole Lens – CCL1222PMP

CCL1222PMP Pinhole lens 22mm 1/2″ 15° HD CCTV M12 mount lens for Covert Surveillance, hidden camera

22mm M12 Pinhole Lens | 15° FOV F1.6 2MP Lens

The 22mm M12 Pinhole Lens is a compact fixed focal lens designed for embedded imaging systems that require a relatively narrow field of view and targeted scene coverage. With a 22mm focal length, 15° horizontal field of view, F1.6 aperture, and 2MP resolution, this M12 pinhole lens is suitable for applications where the camera needs to focus on a specific area rather than capture a wide scene. The M12X0.5 mount and 30mm TTL make it practical for compact camera modules, concealed imaging devices, access control equipment, and other space-constrained systems. The manual focus design also allows optical adjustment during system integration.

For applications requiring a compact lens with controlled framing, the 22mm focal length provides a useful balance between installation distance and target coverage. Compared with shorter focal length M12 lenses, this lens produces a narrower viewing angle, making it suitable for monitoring defined zones, entrances, equipment areas, or other specific targets.

M12 Pinhole Lens Core Highlights

• 22mm Fixed Focal Length – Provides a controlled 15° horizontal field of view for targeted imaging.
• F1.6 Large Aperture – Allows efficient light transmission for embedded imaging applications where illumination conditions may vary.
• 2MP Resolution Support – Suitable for standard monitoring, detection, and recognition tasks within its intended imaging range.
• Compact M12X0.5 Mount – Integrates easily with compact camera modules and embedded vision equipment.
• Manual Focus & Fixed Iris – Enables optical adjustment during system integration while maintaining a simple lens structure.

Targeted Imaging with a 22mm M12 Pinhole Lens

The 22mm M12 Pinhole Lens is particularly suitable when the imaging system needs to monitor a defined target rather than an entire surrounding area. Its 15° horizontal field of view is considerably narrower than typical wide-angle M12 lenses, helping concentrate the camera’s view on a specific zone.

This makes the lens a practical option for:

• Access control and entrance monitoring – Focuses the camera view on doors, gates, checkpoints, or identification areas.
• ATM and self-service equipment – Suitable for compact internal or concealed imaging modules where controlled framing is required.
• Vending and payment equipment – Can be integrated into compact devices for monitoring specific operational areas.
• Industrial equipment monitoring – Provides targeted observation of indicators, operating areas, or machine components.
• Security and concealed camera modules – The compact M12 format is suitable for applications where the optical assembly needs to occupy limited space.
• Smart device imaging – Useful for embedded camera designs requiring a fixed, relatively narrow viewing angle.
• Indoor monitoring systems – Appropriate for corridors, entrances, counters, restricted zones, and other predefined areas.

For systems where the camera must cover a much larger area, a wide-angle or fisheye design may be more appropriate. TOWIN also provides a range of M12 Lenses for different focal lengths and imaging requirements.

Compatible Devices

This 22mm M12 pinhole lens can be considered for integration with:

• Compact M12 camera modules
• Embedded security cameras
• Access control cameras
• ATM and payment terminals
• Vending machines
• Self-service kiosks
• Industrial monitoring cameras
• Smart equipment vision modules
• Concealed or compact camera systems
• Indoor targeted monitoring devices

When selecting a camera module, the sensor format should be matched with the lens image format. For additional guidance on sensor compatibility, see the Sensor Guide.

Lens Selection Considerations

The 22mm focal length is intended for targeted imaging. Before selecting this lens, engineers should consider the camera-to-object distance, required horizontal coverage, sensor size, available installation space, and desired image detail.

Because the lens provides a 15° horizontal field of view, increasing the camera-to-target distance will increase the physical scene width captured by the camera. Conversely, installing the camera closer to the target will produce a smaller monitored area. Engineers can use the FOV Calculator to estimate the relationship between focal length, sensor size, working distance, and field of view.

If the required field of view or working distance differs from this model, TOWIN offers other M12 focal length options and can help identify a suitable optical configuration through its Lens Selection Guide.

Frequently Asked Questions

Q: What type of lens is the 22mm M12 lens?
A: This model is a fixed focal M12 pinhole lens designed for compact embedded imaging systems requiring a controlled 15° horizontal field of view.

Q: What sensor size is compatible with this 22mm pinhole lens?
A: The lens is specified for a 1/2″ image format. The actual sensor and camera module should be checked during system integration to ensure full image coverage.

Q: What applications are suitable for a 22mm M12 pinhole lens?
A: It is suitable for targeted imaging applications such as access control, ATM equipment, kiosks, vending machines, industrial equipment monitoring, and compact security camera modules.

Q: Is this lens suitable for wide-area surveillance?
A: It is not primarily designed for wide-area surveillance. Its 15° horizontal FOV is better suited to monitoring a defined target or zone. Wider coverage may require a shorter focal length or wide-angle M12 lens.

Q: What does the F1.6 aperture provide?
A: The F1.6 aperture provides a relatively large optical opening, helping the lens collect sufficient light for imaging applications where illumination may vary.

Q: Can the focus be adjusted?
A: Yes. This model uses manual focus, allowing the optical focus to be adjusted during camera assembly and system integration.

Q: What does the M12X0.5 mount mean?
A: M12X0.5 indicates an M12 lens thread with a 0.5mm pitch. It is commonly used for compact camera modules and embedded imaging systems.

Q: How can I determine whether 22mm is the right focal length for my application?
A: The required focal length depends on sensor size, working distance, and desired field of view. You can use TOWIN’s FOV Calculator or contact TOWIN for optical selection assistance.
