CCTV Lens – CCL12516FMP

CCL12516FMP is 16mm IR corrected CCTV lens, 1/2.5″ CS mount lens with Low F-number (Fast Lenses), high resolution 3-Megapixel F1.4 low light sensitive lens.

For additional focal-length options and other professional surveillance configurations, engineers can explore the complete CS-Mount Lenses range.

3MP 16mm CS-Mount IR Corrected CCTV Lens

This 3MP 16mm CS-mount fixed focal lens provides a focused 21° horizontal field of view, F1.4 aperture, and IR-corrected optical performance for targeted surveillance. This longer fixed focal length serves CCTV systems that need concentrated coverage of specific areas instead of broad scene monitoring.

CS-Mount CCTV Lens Core Highlights

• 16mm fixed focal length provides concentrated coverage for defined surveillance targets.
• 21° horizontal FOV helps focus the camera view on a specific monitoring zone.
• F1.4 aperture provides a relatively bright optical configuration for indoor surveillance.
• 0.1m M.O.D. supports close-range imaging when required by the installation.
• IR-corrected optics help maintain focus consistency for visible and near-infrared imaging.

CS-Mount CCTV Lens Applications

Core Application Scenes

This 16mm CS-mount CCTV lens is designed for surveillance installations where the camera needs to concentrate on a relatively narrow target area. With a 21° horizontal field of view, it fits applications that reduce unnecessary peripheral coverage and keep the camera focused on a predefined zone.

The longer 16mm focal length can be useful when the camera is installed farther away from the monitored subject. Typical scenarios include building entrances viewed from a greater distance, restricted-access areas, warehouse aisles, equipment zones, loading areas, and perimeter monitoring points where a narrow, dedicated viewing direction is preferred.

Unlike a wide-angle security lens intended to maximize scene coverage, this fixed focal configuration provides a predictable viewing angle after installation. This can simplify deployment when the camera position and target area are already known.

For selecting the appropriate focal length according to sensor size, camera position, and required coverage, engineers can refer to Towin’s Lens Selection Guide.

Compatible Device List

• 1/2.5″ 3MP CCTV cameras: Designed for surveillance cameras using 1/2.5″ image sensors and requiring up to 3MP optical performance.
• CS-mount security cameras: Compatible with camera bodies using a CS mounting interface.
• Perimeter monitoring cameras: The 21° FOV is suitable for monitoring defined sections of a perimeter rather than an entire surrounding area.
• Warehouse and logistics cameras: Useful for viewing selected aisles, loading areas, storage zones, or operational points from a relatively distant mounting position.
• Access-control systems: Can be used where the camera needs to focus on a specific entrance, gate, or restricted-access area.
• Day/night CCTV equipment: IR correction supports systems using near-infrared illumination for nighttime monitoring.

For security deployments involving dedicated monitoring zones, this lens can be integrated into Towin’s Smart Security solutions.

Optical Selection Considerations

The 16mm focal length and 21° horizontal FOV provide a substantially narrower viewing angle than shorter CCTV focal lengths. This makes the lens fit target-oriented surveillance. Users know the installation distance and monitored area ahead of time for such scenarios.

Because the required field of view depends on the camera’s sensor format and installation geometry, engineers should calculate the expected image coverage before selecting the final lens. Towin’s Focal Length Calculator can assist with preliminary focal-length selection.

The lens is specified as IR corrected but no distortion value is provided. Therefore, it should not be marketed as a low distortion lens without additional optical test data. Applications requiring controlled geometric distortion should be evaluated against the requirements outlined in the Distortion Guide.

Designed for targeted CCTV surveillance, perimeter monitoring, access control, warehouse observation, and day/night security systems requiring a 16mm CS-mount fixed focal lens.

Frequently Asked Questions

Q: What type of lens is this 16mm CS-mount lens?
A: This 3MP fixed-focal CCTV lens features a 16mm focal length, CS mount, F1.4 fixed aperture, manual focus adjustment, and IR-corrected optical performance.

Q: What is the horizontal field of view of this 16mm lens?
A: The specified horizontal field of view is 21° for the stated 1/2.5″ image format.

Q: Is this 16mm CS lens a zoom lens?
A: No. It is a fixed focal lens. The focal length is fixed at 16mm, providing a consistent viewing configuration after installation.

Q: What applications are suitable for a 16mm CCTV lens?
A: A 16mm focal length fits targeted surveillance applications such as perimeter sections, warehouse areas, access points, loading zones, and other predefined monitoring targets. Users need a narrower view for these scenarios.

Q: What is the advantage of the F1.4 aperture?
A: The F1.4 aperture provides a relatively bright optical configuration, which can be beneficial for CCTV systems operating in indoor or reduced-light environments.

Q: What does IR corrected mean?
A: IR correction is designed to reduce focus shifts between visible and near-infrared wavelengths, helping maintain more consistent focus in day/night surveillance systems.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.1m, allowing the lens to focus on relatively close subjects when the installation requires short-distance imaging.

Q: Is this lens suitable for machine vision measurement?
A: The supplied specifications identify the lens as a 3MP CS-mount fixed focal configuration, but they do not specify machine-vision parameters such as distortion, MTF, telecentricity, or measurement accuracy. Therefore, application-specific optical validation is recommended before using it for precision measurement.
