Pinhole Lens – CCL127042PMP

CCL127042PMP Pinhole lens 4.2mm 1/2.7″ IR 3MP HD CCTV M12 mount lens for Covert hidden Surveillance

4.2mm 1/2.7″ M12 Wide Angle Pinhole Lens

This 4.2mm M12 pinhole lens is designed for compact camera systems that require broad scene coverage, close-range imaging, and a space-efficient optical configuration. With a 1/2.7″ image format, 3MP resolution, 100° diagonal FOV, 77° horizontal FOV, and an F2.4 fixed aperture, it is well suited for access control, indoor monitoring, embedded security, and compact vision devices.

The 4.2mm focal length provides a wide viewing perspective while offering a slightly more focused field of view than shorter wide-angle configurations. Its M12X0.5 mount, 13mm TTL, manual focus, and 0.1m minimum object distance provide a practical optical configuration for compact camera modules installed close to the monitored area.

Pinhole Lens Core Highlights

• 4.2mm wide-angle focal length provides broad scene coverage for compact camera installations.
• 100° diagonal and 77° horizontal FOV support wide-area monitoring while maintaining a more focused perspective than ultra-short focal lengths.
• 3MP resolution provides suitable image detail for compact security and embedded imaging systems.
• 0.1m M.O.D. supports close-range observation where the camera is installed near the target area.
• M12X0.5 mount and 13mm TTL simplify integration into compact camera modules and space-constrained housings.

Pinhole Lens Applications & Compatible Devices

Access Control and Entrance Monitoring

The combination of a 4.2mm focal length and 77° horizontal FOV makes this lens suitable for monitoring defined entrance areas, access points, counters, and indoor passageways. It provides broad horizontal coverage without using an extremely short focal length.

The 0.1m M.O.D. is particularly useful when the camera is installed close to an access point or other monitored subject. The lens can therefore be considered for compact access-control camera modules where close-range coverage is important.

Embedded Security Devices

This 4.2mm pinhole lens is suitable for embedded security equipment where camera size and viewing coverage need to be balanced. The 100° diagonal FOV allows the camera to capture a broad scene, while the fixed focal design keeps the optical configuration straightforward.

Potential applications include:

• Access control terminals
• Smart door monitoring
• Indoor security cameras
• Video intercom systems
• ATM and kiosk camera modules
• Self-service equipment
• Embedded IoT cameras
• Compact monitoring devices

The lens can also be evaluated for TOWIN’s Smart Security solutions.

Close-Range Wide-Angle Imaging

A key advantage of this configuration is the combination of wide-angle coverage and 0.1m M.O.D. This allows the lens to be considered for compact devices that need to observe nearby subjects while maintaining a relatively broad viewing area.

The lens may be used for monitoring equipment interfaces, entrances, counters, compact indoor spaces, and other applications where the camera-to-target distance is short.

When designing the camera system, sensor dimensions and installation distance should be considered together with the required image coverage. TOWIN’s FOV Calculator can help evaluate the required viewing angle.

Compact M12 Camera Integration

The M12X0.5 mount and 13mm TTL make this lens suitable for compact camera assemblies with limited installation space. Manual focus allows the optical system to be adjusted during camera assembly, while the fixed iris and fixed focal length provide a simple configuration for embedded imaging equipment.
