Description
Enhance your surveillance and monitoring systems with our budget-friendly 3MP 12mm M12 Fixed Focal Lens. Expertly crafted with a premium 6G (6-layer all-glass) optical structure and a bright F2.0 large aperture, this lens is fully optimized for 1/2.5″ and 1/2.7″ CMOS sensors. Featuring an integrated IR Cut Filter (IR cut) to ensure vivid day-and-night color accuracy, it delivers a focused 28° horizontal field of view. It stands out as an exceptionally reliable, high-performance option for cost-sensitive CCTV security, commercial IoT devices, and lightweight industrial vision tracking.
Key Highlights
- Narrow-Angle Telephoto Compression: The 12mm focal length yields a tight 28° horizontal FOV on 1/2.5″ sensors, making it easy to isolate license plates, faces, or far-away objects.
- Bright F2.0 Aperture Performance: Maximizes light throughput to ensure clear imaging in dimly lit corridors or low-light industrial production lines, outperforming standard F2.4/F2.8 lenses.
- Rugged 6G All-Glass Elements: Built with 6 layers of optical glass to resist focus shifting and blurring caused by fluctuating temperatures inside sealed outdoor or factory enclosures.
- Seamless Multi-Format Integration: Universally compatible with both 1/2.5″ and 1/2.7″ sensor formats, preventing vignetting and simplifying system migration.

Applications & Compatibility
Core Application Scenarios
This 3MP 12mm M12 lens is specifically designed for security environments and tracking loops where mid-range magnification is required within a compact installation footprint. It excels in CCTV security setups, such as narrow property hallways, warehouse aisles, community gate access points, and parking garage cash registers where wide angles create unnecessary data waste. With a 0.3m minimum object distance, it provides reliable structural tracking in commercial IoT smart devices, retail kiosk payment cameras, and facial-recognition turnstiles. Furthermore, it easily replaces standard lenses in entry-level Industrial Machine Vision lines for conveyor box counting, package sorting, and logistics verification under consistent workplace illumination.
Compatible Device List
- Sensors: Fully compatible with 1/2.5″, 1/2.7″, 1/2.8″, and 1/3″ mainstream high-definition CMOS sensors (such as Sony, OmniVision, and SmartSens lines).
- Security & IP Cameras: Seamlessly fits customized 1080P/3MP dome or bullet IP camera modules from Hikvision, Dahua, Uniview, and Tuya-enabled smart home devices.
- Industrial & Board Cameras: Directly mounts onto standard M12 board-level cameras used in light manufacturing and code checking.
- Embedded Development Kits: Pairs cleanly with the Raspberry Pi Camera Module, Jetson Nano camera fixtures, and custom microcontroller vision shields.

Frequently Asked Questions
- Q: What is the main advantage of a 12mm focal length on a 1/2.5″ sensor?
- A: A 12mm focal length narrows the horizontal view to 28°. This creates a mechanical magnification effect, helping you clearly zoom in on specific targets like cash registers, entry gates, or distant doorways without buying expensive variable lenses.
- Q: Why does the 6G all-glass structure matter for outdoor cameras?
- A: The 6G layout consists of 6 layers of premium optical glass. Low-cost hybrid or plastic lenses expand and warp when exposed to sunlight or factory heat, causing the image to blur. Glass maintains absolute stability and sharp 3MP resolution at all times.
- Q: Does this M12 lens have a built-in day/night filter?
- A: Yes. The lens includes an integrated IR Cut Filter (IR cut). It automatically blocks infrared light during the day to prevent color distortion, delivering natural and true-to-life color rendering for security monitoring.
- Q: Will this lens experience vignetting or dark corners on my sensor?
- A: No. It is optically optimized to fully support up to a 1/2.5″ image circle. It will provide clean, evenly lit corners on 1/2.5″, 1/2.7″, 1/2.8″, and smaller sensors.
- Q: Is the aperture adjustable for low-light conditions?
- A: No, this lens has a fixed F2.0 iris. The F2.0 rating is quite large for a telephoto M12 lens, allowing maximum light passage to enhance visibility in low-light environments or night scenes.
- Q: How does the 0.3m Minimum Object Distance (M.O.D.) affect usage?
- A: It allows the lens to focus on objects as close as 30cm away. This makes it highly versatile, allowing it to transition from a remote courtyard camera to a close-up retail kiosk or document sorting camera.
