Pinhole Lens – CCL14021PMP

CCL14021PMP Pinhole lens 2.1mm 1/4″ IR MP HD CCTV M12 mount lens for Covert hidden Surveillance

2.1mm 1/4″ M12 MP Pinhole Wide Angle Lens

This 2.1mm M12 pinhole lens is designed for compact camera modules that require a broad viewing area within a limited installation space. Supporting a 1/4″ image format, MP resolution, and an ultra-wide 125° diagonal FOV, it provides extensive scene coverage for embedded monitoring, security devices, access control, and other compact vision systems.

With a 2.1mm fixed focal length, F2.4 aperture, manual focus, and M12X0.5 mount, this lens combines wide-angle imaging with a compact optical configuration. The 0.3m minimum object distance also makes it suitable for applications where cameras need to observe relatively close scenes.

M12 Pinhole Lens Core Highlights

• 2.1mm Ultra-Wide Focal Length — Provides broad scene coverage for space-constrained camera installations.
• 125° Diagonal FOV — Covers a large viewing area with 99° horizontal and 74° vertical FOV.
• 1/4″ MP Imaging — Designed for compact imaging systems requiring megapixel-class image capture.
• M12X0.5 Compact Mount — Supports integration into small camera modules and embedded vision equipment.
• 0.3m M.O.D. — Enables practical close-range imaging for indoor and compact-device applications.

M12 Pinhole Lens Applications & Compatible Devices

Wide-Area Embedded Monitoring

The 2.1mm focal length is particularly suitable when the camera must capture a large area from a relatively short installation distance. Its 125° diagonal FOV can help reduce blind areas in compact monitoring equipment where a longer focal length would provide insufficient scene coverage.

Designed for wide-area embedded monitoring applications.

Typical applications include compact security cameras, indoor monitoring modules, access-control equipment, self-service terminals, and embedded camera systems.

Access Control & Entry Monitoring

The wide viewing angle can help capture people approaching an access point without requiring a large camera enclosure. The 0.3m M.O.D. also supports close-range scenes around doors, gates, terminals, and other controlled-access equipment.

For selecting the appropriate focal length and field of view for an access-control camera, refer to the Lens Selection Guide.

Compact Security Camera Modules

With its M12X0.5 mount, fixed 2.1mm focal length, and 12.29mm TTL, this lens is suitable for compact camera architectures where optical size and broad coverage are both important. The fixed F2.4 aperture provides a straightforward optical configuration for embedded camera integration.

It can be considered alongside other Megapixel Pinhole Lenses when selecting a lens for discreet or space-constrained camera modules.

Indoor Wide-Angle Vision

The 99° horizontal FOV provides substantial lateral coverage for indoor scenes such as equipment monitoring, kiosks, service counters, intercom systems, and compact observation devices. The 2.1mm focal length is especially useful when the camera must capture a wider scene without increasing the physical size of the camera assembly.

Compatible Device List

This 2.1mm M12 pinhole lens can be integrated into:

• Compact security camera modules
