CCL1245PMP Pinhole lens 1/2″ 45mm HD CCTV M12 mount lens Covert hidden Surveillance high temperature metallurgy

45mm M12 Pinhole Lens

This 45mm M12 pinhole lens is designed for compact camera systems that require a narrow field of view and focused observation of a specific target. With a 45mm fixed focal length, 8° horizontal FOV, 2MP resolution, and a fast F1.6 aperture, the lens is optimized for targeted imaging rather than wide-area scene coverage. The 1/2″ image format and M12×0.5 mount make it suitable for compact embedded camera modules and space-constrained optical assemblies.

Designed for targeted security monitoring, access control, equipment observation, and discreet embedded imaging applications, this fixed focal pinhole lens provides a concentrated viewing angle for applications where minimizing unnecessary background coverage is important. Its 0.2m minimum object distance provides flexibility for close installation scenarios, while the 51.2mm TTL offers a defined mechanical configuration for camera integration.

M12 Pinhole Lens Core Highlights

• 45mm fixed focal length provides a concentrated viewing angle for targeted observation.
• 8° horizontal FOV is suitable for applications requiring narrow scene coverage and focused imaging.
• F1.6 aperture provides strong light-gathering capability for indoor and relatively low-light environments.
• 2MP resolution supports standard megapixel compact camera applications.
• M12×0.5 mount enables integration with compact embedded camera systems.

M12 Pinhole Lens Applications

Targeted Security Monitoring

The 8° horizontal field of view makes this 45mm M12 pinhole lens particularly suitable for applications where the camera needs to monitor a clearly defined target instead of an entire room or large area. It can be considered for monitoring a specific doorway, restricted zone, equipment position, or other predetermined area.

The narrow FOV can also help reduce unnecessary peripheral information when the monitoring system is designed around a specific target.

Long-Range Target Observation

The 45mm focal length provides a substantially narrower viewing angle than short focal length M12 lenses. This makes the lens appropriate for camera systems designed to observe specific targets from a greater installation distance, provided the required target coverage is compatible with the sensor and working distance.

Typical examples may include monitoring a designated entrance, equipment position, control point, or other fixed area.

Access Control & Entry Monitoring

A narrow field of view can be useful in access control systems where the camera is positioned toward a particular interaction zone. Instead of capturing a broad surrounding environment, the lens can concentrate imaging on a door, gate, identification area, or designated user position.

The manual focus configuration allows the optical system to be adjusted according to the actual installation distance.

Equipment & Instrument Observation

The lens can be integrated into compact camera systems used to monitor specific instruments, displays, control panels, or equipment components. The 8° FOV helps limit the captured scene to the intended observation area, which can be advantageous when the monitoring target occupies only a small portion of the overall environment.

For applications involving specific optical and mechanical constraints, TOWIN’s Lens Selection Guide provides additional guidance on focal length, sensor size, FOV, and working distance.

Discreet Embedded Camera Systems

The pinhole configuration is suitable for compact camera designs where the optical opening needs to remain small and unobtrusive. Combined with an M12×0.5 mount, the lens can be incorporated into OEM camera modules, embedded monitoring devices, access equipment, and other space-constrained imaging systems.

TOWIN also provides dedicated M12 Lens solutions for compact embedded imaging applications.

Compatible Devices

This 45mm 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 observation cameras
• Instrument monitoring modules
• Control panel monitoring systems
• Compact OEM camera assemblies
• Targeted observation devices
• Space-constrained embedded vision systems

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

Why Choose a 45mm Pinhole Lens?

The main advantage of this lens is its 45mm focal length combined with an 8° horizontal FOV. Compared with short focal length pinhole lenses, this configuration provides a much more concentrated viewing angle, making it better suited to targeted observation.

The F1.6 aperture is also important for compact camera applications. Its relatively fast optical configuration can provide increased light-gathering capability compared with slower apertures, which may be beneficial when the available illumination is limited.

When designing the camera system, the 8° horizontal FOV should be evaluated together with the sensor dimensions and installation distance. TOWIN’s FOV Calculator can help estimate the expected image coverage.
