CCTV Lens – CCL12508FMP

CCL12508FMP is F1.4 Low F-number CCTV lens, 1/2.5″ 8mm CS mount fixed-focus fixed-iris wide-angle lens, IR corrected, 3-Megapixel resolution.

For additional CS-mount optical options, engineers can review Towin’s CS-Mount Lenses product range, which includes fixed focal, manual iris, P-Iris, and other surveillance lens configurations.

3MP 8mm CS-Mount IR Corrected CCTV Lens

This 3MP 8mm CS-mount fixed focal lens combines an F1.4 aperture, 41° horizontal field of view, IR-corrected optical performance, and a short 0.1m minimum object distance. Its fixed 8mm focal length provides a stable viewing configuration for compact CCTV cameras and surveillance systems requiring consistent framing.

CS-Mount CCTV Lens Core Highlights

• 8mm fixed focal length delivers consistent framing for dedicated surveillance positions.
• F1.4 aperture provides a relatively bright optical configuration for challenging lighting environments.
• 41° horizontal FOV offers a focused viewing angle for targeted monitoring.
• 0.1m minimum object distance supports close-range imaging applications.
• IR-corrected optical design helps maintain focus consistency across visible and near-infrared wavelengths.

CS-Mount CCTV Lens Applications

Core Application Scenes

This 8mm CS-mount fixed focal lens is designed for surveillance installations where the camera has a defined monitoring area and a stable field of view is preferred over adjustable zoom. The 41° horizontal field of view provides a more focused perspective than typical wide-angle security lenses, making it suitable for monitoring specific zones rather than maximizing overall scene coverage.

The F1.4 aperture is particularly useful in indoor security environments, entrances, corridors, access points, and controlled monitoring zones where available light may vary throughout the day. The fixed focal design also simplifies optical configuration because the viewing angle remains consistent once the lens has been installed and focused.

With a 0.1m minimum object distance, this lens can also support relatively close-range imaging, such as monitoring equipment interfaces, small access areas, display zones, or objects positioned near a camera.

For systems where infrared illumination is used, the IR-corrected optical design helps reduce wavelength-related focus shifts. Engineers selecting a lens for changing lighting conditions can also consult Towin’s Lens Selection Guide.

Compatible Device List

• 1/2.5″ 3MP CCTV cameras: Designed for surveillance cameras using 1/2.5″ image sensors with up to 3MP imaging requirements.
• CS-mount security cameras: The CS mounting interface allows integration with compatible professional CCTV camera bodies.
• Indoor surveillance cameras: Suitable for corridors, entrances, reception areas, access-control zones, and other defined monitoring locations.
• Low-light security systems: The F1.4 aperture provides a relatively bright optical configuration for indoor and reduced-light environments.
• Day/night CCTV systems: IR correction makes the lens suitable for systems that combine visible-light imaging with near-infrared illumination.
• Close-range monitoring devices: The 0.1m MOD can accommodate applications where the monitored subject is positioned relatively close to the camera.

For dedicated security applications, the lens can be considered alongside Towin’s Smart Security solutions, particularly for fixed-position monitoring systems requiring a stable viewing angle.

Optical Selection Considerations

The 8mm fixed focal length and 41° horizontal FOV make this lens more suitable for targeted monitoring than for very wide-area scene coverage. Before installation, engineers should consider the camera mounting height, object distance, sensor format, and required horizontal coverage.

For applications where a different focal length may be required, Towin’s Focal Length Calculator can help estimate the focal length needed for a specific working distance and scene width.

The lens is not positioned as a low-distortion optical solution because no distortion specification is provided. For applications where geometric accuracy is important, engineers should evaluate distortion requirements using the Distortion Guide before selecting the final lens.

Frequently Asked Questions

Q: What type of lens is this 8mm CS-mount lens?
A: It is a 3MP fixed focal CCTV lens with an 8mm focal length, CS mount, F1.4 aperture, manual focus, and IR-corrected optical performance.

Q: What is the field of view of the 8mm lens?
A: The specified horizontal field of view is 41° when used with the stated 1/2.5″ image format.

Q: Is this lens a zoom lens?
A: No. It is a fixed focal lens. The focal length is fixed at 8mm, so the viewing angle does not change through optical zoom.

Q: What camera sensor is this CS lens designed for?
A: The specified image format is 1/2.5″, with a resolution rating of 3 megapixels.

Q: What is the advantage of the F1.4 aperture?
A: F1.4 provides a relatively bright optical configuration, which can be useful for indoor surveillance and other applications where available illumination is limited.

Q: What does IR corrected mean on this CCTV lens?
A: IR correction reduces focus shifts between visible and near-infrared wavelengths and maintains steadier focus when a camera uses infrared illumination.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.1m, allowing the lens to image subjects positioned relatively close to the camera.

Q: What applications are suitable for this CS-mount lens?
A: You can use it for fixed-position CCTV surveillance, indoor security cameras, access monitoring, corridors, entrances, and day/night surveillance systems. An 8mm focal length and 41° horizontal field of view satisfy the coverage requirements for these applications.
