• CS-Mount configuration integrates easily with compatible professional CCTV camera systems.

CS-Mount CCTV Lens Applications

Core Application Scenes

This 12-50mm CS-Mount zoom lens is developed for surveillance systems where the camera needs to cover different distances without replacing the optical assembly. Its 12mm wide-end focal length provides a relatively broad monitoring view, while the 50mm telephoto end allows operators to obtain a narrower view of distant subjects.

For professional security installations, the manual zoom structure allows the installer to adjust the field of view according to the actual camera position and surveillance area. This makes the lens suitable for entrances, building perimeters, industrial sites, parking areas, warehouse corridors, and other locations where the monitoring distance can vary considerably.

The F1.6 maximum aperture is beneficial for surveillance cameras operating under changing illumination. Combined with IR correction, the lens can support imaging systems that use visible light during the day and near-infrared illumination for nighttime monitoring.

For projects requiring different focal lengths, sensor formats, or optical characteristics, the lens can also be evaluated alongside other CS-Mount Lenses and professional surveillance optics.

For applications involving changing monitoring distances, our Smart Security solutions provide additional guidance on selecting suitable optical components for surveillance systems.

When choosing a lens for a specific sensor and monitoring distance, the Lens Selection Guide can help engineers evaluate focal length, sensor format, field of view, and other optical parameters.

You can also use the FOV Calculator to estimate the relationship between sensor size, focal length, and field of view before selecting the final lens configuration.

Frequently Asked Questions

Q: What type of camera is this 12-50mm lens designed for?
A: This lens is designed primarily for professional CCTV and security cameras with a CS-Mount interface and a 1/1.7″ image sensor.

Q: Is this a fixed focal length lens?
A: No. The lens provides a 12–50mm focal length range with manual zoom, allowing the user to adjust the viewing angle according to the monitoring distance.

Q: What resolution does this CS-Mount zoom lens support?
A: The lens is specified for 5 Megapixel imaging and is designed for applications requiring detailed surveillance images.

Q: What is the advantage of the IR-corrected optical design?
A: IR correction helps maintain more consistent optical focus when a camera operates across visible and near-infrared wavelengths, which is useful for day/night surveillance systems.

Q: What field of view can this lens provide?
A: The diagonal FOV ranges from 46° at the 12mm wide end to 11° at the 50mm telephoto end. The horizontal FOV ranges from 36° to 9°, while the vertical FOV ranges from 27° to 6.5°.

Q: Can the iris, focus, and zoom be adjusted manually?
A: Yes. The lens uses manual iris, manual focus, and manual zoom mechanisms, giving installers direct control during camera installation and optical calibration.
