• DC auto iris enables automatic aperture adjustment according to changing illumination
• CS mount supports integration with compatible CCTV camera systems

CS-Mount Pinhole Lens Applications

The combination of a 4mm focal length, 65° horizontal FOV, F1.8 aperture, and DC auto iris makes this pinhole lens particularly suitable for security cameras that need discreet observation while maintaining useful scene coverage. Its 0.15m M.O.D. also allows close-range subjects to be captured in compact monitoring environments.

Typical applications include indoor security monitoring, access-point surveillance, retail observation, building security, concealed camera systems, and compact CCTV equipment. The DC auto iris is especially useful in environments where illumination can change during operation, helping the camera maintain a more consistent exposure as lighting conditions vary.

Compatible devices can include 1/3″ security camera modules, CS-mount CCTV cameras, indoor surveillance cameras, embedded monitoring systems, and specialized discreet imaging equipment.

Designed for discreet security surveillance and compact CCTV monitoring applications.

For projects requiring a compact and discreet optical configuration, TOWIN’s Megapixel Pinhole Lens range provides additional pinhole lens options. For broader security applications, you can also explore the Smart Security solution for optical solutions designed around surveillance imaging requirements.

When matching this lens with a camera sensor, sensor format and optical coverage should be evaluated together. TOWIN’s Sensor Guide explains how sensor size affects lens selection, while the Lens Selection Guide can help determine the appropriate focal length and lens configuration for a specific camera system.

Why Choose This 4mm Pinhole Lens?

This lens combines the discreet characteristics of a pinhole lens with the practical interface and exposure control of a CS-mount CCTV lens. The 4mm focal length provides a useful balance between coverage and image detail, while the F1.8 aperture supports applications where available light may vary. The DC auto iris further improves its suitability for security environments with changing illumination.

The 100mm TTL and 12.50mm B.F.L. provide defined mechanical parameters for camera integration, while manual focus allows the optical system to be adjusted during installation according to the actual working distance.

For OEM and ODM projects, TOWIN can evaluate customized requirements involving focal length, field of view, mount, mechanical dimensions, aperture configuration, and other optical parameters. Contact TOWIN to discuss your project requirements.
