Description
This 12mm fixed focal M12 lens is engineered for 1/3-inch image sensors with strict distortion control. Built with a 5-group 5-element glass optical structure and fixed F1.6 aperture, it delivers sharp, low-deformation surveillance images across daytime monitoring. The compact TTL length of 20.95mm fits tightly inside mini-sized camera housings, making it a mature optical choice for compact CCTV security cameras and miniature visual equipment.
Key Product Highlights
Field of View & Focal Length Advantages
Precise 12mm focal length brings 29° diagonal FOV, 23° horizontal FOV and 17° vertical FOV. Eliminates over-wide blind zones and narrow viewing limitations, ideal for medium-distance fixed-point monitoring without repeated lens replacement.
Optical Performance
Strictly controlled distortion below -2.4%. The 5G all-glass lens effectively suppresses image edge warping, far outperforming plastic lenses and ordinary single-group glass lenses for clear undistorted footage. The fixed F1.6 aperture guarantees stable light intake without light fluctuation caused by adjustable iris.
Hardware Compatibility
Standard M12×0.5 screw mount, perfectly matched with all mainstream 1/3-inch CMOS sensors. Manual focus supports fine-tuning after installation; fixed zoom structure avoids focal drift during long-term outdoor operation.
Strict Quality Assurance
Each lens undergoes full optical testing before delivery. No focal shift or light leakage after long-time continuous work, suitable for 24/7 non-stop monitoring tasks.

Product Application Scenarios and Compatible Devices
Core Application Scenarios
This megapixel M12 fixed focal lens is mainly deployed for small outdoor mini CCTV cameras, parking lot fixed-point monitoring, retail shop indoor anti-theft cameras, elevator car monitoring modules, mini vehicle auxiliary monitoring cameras, and small IoT visual capture devices. Its compact 20.95mm total length fits narrow camera shell space without structural modification. Low distortion ensures license plates and human facial features remain undeformed at medium monitoring distance, greatly improving video recognition accuracy for long-term continuous monitoring work.
Compatible Devices List
Fully compatible with all mainstream 1/3-inch megapixel CMOS image sensors. It adapts to Tuya smart mini security cameras, elevator dedicated monitoring modules, small vehicle mounted cameras, low-power IoT surveillance modules, and DIY miniature vision cameras. We accept custom optical polishing and parameter adjustment to match different sensor chips and camera structural requirements for bulk orders.
Designed for compact CCTV surveillance application.
Frequently Asked Questions
Q: Can this M12 lens work with 1/2.5-inch sensors?
A: It is optimized strictly for 1/3″ sensors. Using a larger sensor will lead to vignetting at the image edges.
Q: Does this lens support night IR infrared monitoring?
A: This model is a standard daylight fixed lens without IR correction. If you need day-night dual-use versions, we can provide IR corrected variants.
Q: Is the M12 thread standard for all mini camera modules?
A: Yes, M12×0.5 is the universal industrial miniature lens thread, compatible with most mainstream small camera PCB holders.
Q: Can I adjust the aperture on this lens?
A: This version has a fixed F1.6 iris; adjustable aperture versions are available upon request.
