CCTV Lens – CCL13030810M

CCL13030810M is CCTV lens 1/3″ 3-8mm manual zoom lens, CS mount lens, manual iris and focus, VGA resolution, F1.0 for low light sensitivity.

1/3″ 3–8mm F1.0 CS-Mount Manual Zoom CCTV Lens

This 1/3″ VGA 3–8mm CS-mount lens is a manual zoom CCTV lens designed for security cameras and video surveillance systems requiring flexible field-of-view adjustment. Its 3–8mm focal length provides a horizontal FOV from 81° to 41°, while the F1.0 aperture supports strong light transmission for imaging in challenging lighting conditions. With manual iris, manual focus, manual zoom, and a 0.2m minimum object distance, this lens provides practical optical adjustment for different camera installation distances and monitoring areas.

CS-Mount Manual Zoom CCTV Lens Highlights at a Glance

• 3–8mm variable focal length for flexible monitoring coverage
• 81°–41° horizontal FOV supports both wide-area and narrower scene observation
• F1.0 maximum aperture provides high light transmission for low-light surveillance environments
• CS-mount design is compatible with a wide range of CS-mount security cameras
• Manual iris, focus, and zoom allow installers to optimize the lens for a specific scene

CS-Mount Manual Zoom CCTV Lens Applications

Core Application Scenes

This lens is designed for applications where installers need to adjust both viewing coverage and image framing after the camera is installed. At 3mm, the lens provides an 81° horizontal field of view for relatively broad scene coverage. Moving toward 8mm narrows the field of view to 41°, making it possible to concentrate on a smaller monitoring area or a more distant target.

Typical applications include:

• Indoor CCTV surveillance
• Retail and commercial security cameras
• Building entrance monitoring
• Corridor and lobby surveillance
• Warehouse and facility monitoring
• General-purpose security video systems
• Camera installations requiring manual zoom adjustment

The F1.0 aperture is particularly useful when the surveillance scene has limited available light, while the manual iris allows the installer to adjust the amount of light reaching the sensor according to the application.

Compatible Devices

This lens is suitable for:

• 1/3″ CCTV cameras
• CS-mount security cameras
• Analog or compatible video surveillance camera systems
• Fixed-position indoor surveillance cameras
• Security cameras requiring adjustable focal length

For applications where the camera uses a different optical interface, users can review the complete CS-Mount Lenses range to identify other compatible optical configurations.

Designed for indoor CCTV, commercial security, facility monitoring, and adjustable-field-of-view surveillance applications.

Frequently Asked Questions

Q1: What cameras are compatible with this 3–8mm lens?
A: This lens uses a CS mount and is designed for 1/3″ camera sensors. The camera should also provide sufficient back focal compatibility with the lens specifications.

Q2: Is this a fixed focal length lens?
A: No. The focal length can be manually adjusted from 3mm to 8mm, allowing the installer to change the viewing angle and image framing.

Q3: What is the horizontal field of view of this lens?
A: The horizontal FOV ranges from 81° at 3mm to 41° at 8mm. The shorter focal length provides wider scene coverage, while the longer focal length provides a narrower view.

Q4: Is this lens a fisheye lens?
A: No. Although the 3mm setting provides a relatively wide 81° horizontal FOV, the available specification does not indicate a fisheye optical design.

Q5: What does the F1.0 aperture mean for surveillance applications?
A: F1.0 is the lens’ maximum aperture. A larger aperture lets more light hit the camera sensor, ideal for low-light surveillance scenarios.

Q6: Can the iris, focus, and zoom be adjusted automatically?
A: No. The specification lists manual iris, manual focus, and manual zoom. These parameters are adjusted by the installer rather than by an integrated motorized mechanism.

Q7: What is the minimum object distance?
A: The minimum object distance is 0.2m, allowing the lens to focus on relatively close subjects when properly installed and adjusted.

Q8: How can I determine whether this lens is suitable for my camera?
A: Check the camera’s sensor format, mount type, required field of view, and installation distance. TOWIN’s Lens Selection Guide provides additional guidance for matching an industrial or security camera with an appropriate lens.
