Pinhole Lens – CCL13040PMMPR

CCL13040PMMPR Pinhole lens 4mm 1/3″ manual iris HD CCTV CS-mount lens Covert hidden Surveillance-1

4mm 2MP CS-Mount IR Corrected Pinhole Lens

This 4mm 2MP CS-mount pinhole lens is designed for compact surveillance and embedded imaging systems that require discreet installation, reliable image quality, and infrared compatibility. With a 1/3″ image format, 70° horizontal field of view, F1.8 aperture, and manual focus, this fixed focal pinhole lens provides a practical optical solution for security cameras, concealed monitoring devices, and space-constrained vision systems.

CS-Mount Pinhole Lens Core Highlights

• 4mm Fixed Focal Length – Provides a stable 70° horizontal field of view for controlled monitoring areas.
• 2MP Resolution Support – Suitable for 2MP security and surveillance camera modules.
• F1.8 Aperture – Provides good light-gathering capability for indoor and variable-light imaging environments.
• CS-Mount Design – Compatible with CS-mount camera systems and provides convenient integration into professional CCTV equipment.
• IR Corrected Optical Design – Helps maintain consistent focus between visible and infrared illumination, supporting day/night surveillance applications.

CS-Mount Pinhole Lens Applications

Compact and Discreet Security Monitoring

The primary advantage of a pinhole lens is its compact optical profile, making it suitable for applications where the camera needs to remain visually unobtrusive. The 4mm focal length and 70° horizontal FOV provide a balanced coverage area without requiring an ultra-wide fisheye design.

Typical applications include:

• Discreet security cameras
• Indoor surveillance systems
• Access control cameras
• ATM and kiosk monitoring
• Retail security equipment
• Embedded monitoring modules
• Compact CCTV systems
• Concealed observation equipment

Designed for discreet security monitoring and compact embedded camera applications.

IR-Compatible Day & Night Imaging

The IR correction is particularly valuable for surveillance systems that switch between visible-light and infrared illumination. By optimizing the lens for infrared imaging, the lens can help reduce focus shifts when the imaging system changes operating wavelengths.

This makes it suitable for:

• Day/night security cameras
• IR-assisted surveillance cameras
• Indoor monitoring systems
• Low-light observation equipment
• Security devices using IR illumination

For applications requiring infrared-compatible optics, this lens can be considered alongside TOWIN’s IR Corrected Lens solutions and optical design resources.

CS-Mount Camera Integration

With a CS mount, this lens is intended for camera systems using the CS interface rather than M12 or other miniature mounts. The 90.5mm TTL provides a relatively extended optical structure, which should be considered when matching the lens with the camera housing and mechanical installation space.

For broader CS-mount product selection, see TOWIN’s CS-Mount Lenses portfolio.

Optical Selection Considerations

When selecting a pinhole lens, the focal length, sensor format, field of view, aperture, mounting interface, and infrared requirements should be evaluated together. This 4mm lens is designed around a 1/3″ sensor format and 70° horizontal FOV, making it suitable for applications that need moderate wide-area coverage while maintaining a fixed optical configuration.

For additional guidance, users can review the TOWIN Lens Selection Guide and Sensor Guide when matching the lens to a camera sensor.

Frequently Asked Questions

Q: What type of lens is this product?
A: This is a 4mm fixed focal pinhole lens designed for compact and discreet imaging systems. It uses a CS mount and supports a 1/3″ image format.

Q: What is the field of view of this 4mm pinhole lens?
A: The lens provides a 70° horizontal field of view on a 1/3″ sensor, making it suitable for moderate wide-area surveillance and monitoring applications.

Q: Is this lens suitable for CCTV cameras?
A: Yes. Its 2MP resolution, CS mount, F1.8 aperture, fixed 4mm focal length, and IR correction make it suitable for various compact CCTV and security camera systems.

Q: What does IR correction mean for this lens?
A: IR correction helps the lens maintain more consistent optical focus when the camera operates across visible and infrared wavelengths, which is useful for day/night surveillance systems.

Q: Can this lens be used for day and night surveillance?
A: Yes. The IR-corrected design makes it suitable for camera systems that use infrared illumination for nighttime or low-light monitoring.

Q: Is the aperture adjustable?
A: Yes. The lens uses a manual iris, allowing the aperture to be manually adjusted according to the application’s lighting conditions.

Q: Is the focus adjustable?
A: Yes. The lens has manual focus adjustment and a minimum object distance of 0.15m, providing flexibility during camera installation and optical setup.

Q: What camera mount does this pinhole lens use?
A: This product uses a CS mount and is therefore intended for camera systems designed for CS-mount lenses.
