Description
This professional-grade 12mm CS-mount CCTV lens delivers high-performance 3MP resolution specifically optimized for narrow-angle, long-distance surveillance and industrial imaging. Featuring a class-leading F1.2 aperture and full IR correction, it ensures high-contrast, razor-sharp details in both low-light conditions and infrared night-vision modes. Engineered as a rugged fixed focal industrial lens, it features precision manual adjustment rings to give system integrators total control over focus and exposure, making it the ultimate choice for clear critical asset monitoring and machine vision applications.
Product Highlights
- 3MP High-Definition Clarity: Engineered with premium optical glass to support up to 3 Megapixel resolution, delivering crisp details and resolving complex textures that standard megapixel lenses blur.
- Ultra-Bright F1.2 Aperture: The exceptionally large F1.2 manual iris gathers maximum light, producing clear, colorful images in low-light environments without relying heavily on digital noise reduction.
- Long-Range 28.5° Telephoto Field of View: The 12mm fixed focal length narrows the horizontal FOV to 28.5 degrees, allowing you to capture far-away targets like faces, license plates, or small parts with zero wide-angle distortion.
- Flawless Day & Night Co-Focal Performance: Advanced IR corrected lens multi-coating prevents focus shift under infrared illumination, guaranteeing perfectly sharp day/night transitions without requiring recalibration.

Target Applications & Device Compatibility
Core Application Scenarios
The 12mm low distortion lens is specifically optimized for long-range, narrow-angle identification tasks where broad view stretching is a disadvantage. It serves as an excellent ITS lens for intelligent traffic monitoring, such as capturing vehicle plates at toll gates or tracking specific lanes. In retail and commercial security, it excels at corridor surveillance, warehouse aisle tracking, and cash register monitoring, where isolating details at a distance is paramount. Thanks to its close-up focus ability (M.O.D. 0.2m), it is also highly demanded in factory automation (FA lens) for PCB inspection, code scanning on fast conveyor belts, and precise robotic machine vision alignment under controlled factory lighting.
Compatible Device List
- Sensors: Perfectly compatible with standard 1/3″ and smaller (such as 1/4″ or 1/3.2″) high-definition CMOS/CCD image sensors.
- Security Hardware: Seamlessly pairs with premium 3MP/5MP CS-mount CCTV box cameras, IP network cameras, and analog HD surveillance cameras from major brands like Hikvision, Dahua, and Uniview.
- Industrial Vision Equipment: Fits industrial smart cameras, gigabit Ethernet (GigE) cameras, and USB3.0 machine vision cameras that require strict manual exposure locking screws.
- Embedded IoT Platforms: Integrates into customized Tuya smart industrial setups, raspberry pi setups with CS adapters, and access control facial recognition terminal housings.

Frequently Asked Questions
Q: Can this 3MP lens be used on a 5-megapixel or 4K security camera?
A: Yes, but the resulting image quality will be bottlenecked by the lens resolution limit. For optimal optical performance, it is highly recommended to pair this lens with standard 3MP or lower resolution 1/3″ sensors.
A: Yes, but the resulting image quality will be bottlenecked by the lens resolution limit. For optimal optical performance, it is highly recommended to pair this lens with standard 3MP or lower resolution 1/3″ sensors.
Q: What makes this 12mm lens different from a standard wide-angle CCTV lens?
A: While wide-angle lenses focus on broad environmental coverage, this 12mm fixed focal lens narrows the field of view to 28.5°. This acts like a optical zoom, magnifying distant objects to pull out fine details like alphanumeric text or defects.

Q: Does the F1.2 aperture stay wide open, or can I adjust it?
A: It features a manual iris ring. You can manually adjust the aperture from its maximum brightness of F1.2 down to closed settings, allowing you to manually balance the light and depth of field based on your environment.

Q: Is there any geometric or barrel distortion on the edges of the image?
A: Virtually none. Because of its narrow 28.5° horizontal FOV and long focal length, it functions inherently as a low distortion lens, ensuring lines remain perfectly straight from the center to the edge of the frame.

Q: Why is “IR Corrected” important for a 12mm lens?
A: Infrared light has a different wavelength than visible light, causing them to focus at different points. An IR corrected lens ensures both day and night light waves focus on the exact same spot on your 1/3″ sensor, preventing blurry nighttime footage.

Q: Can I use this lens for ultra-close up inspections in industrial assembly lines?
A: Absolutely. Despite being a 12mm tele-photo lens, it features a remarkably short Minimum Object Distance (M.O.D.) of 0.2 meters (20cm). This allows it to capture highly magnified close-ups of small components in FA lens applications.
