Description
Enhance your surveillance and monitoring systems with our cost-effective 3MP 12mm M12 Fixed Focal Lens. Masterfully engineered with a fast F2.0 large aperture, this lens is fully optimized for 1/2.5″ and 1/2.7″ CMOS sensors. Delivering a focused 28° horizontal field of view, it provides excellent mid-range magnification within an ultra-compact footprint. It stands out as an exceptionally reliable, high-performance optical solution for budget-sensitive CCTV security, commercial IoT devices, and lightweight industrial vision tracking applications.
Key Highlights
- Mid-Range Narrow Field (28° HOV): The 12mm focal length compresses the scene to focus on specific targets, making it easy to isolate faces or objects from a distance without losing detail.
- Bright F2.0 Aperture Performance: Maximizes light intake to ensure crisp, clean imagery in dimly lit corridors or low-light industrial environments, outperforming standard F2.4/F2.8 lenses.
- Versatile Multi-Format Integration: Universally compatible with both 1/2.5″ and 1/2.7″ sensor formats, preventing image vignetting and simplifying system migration.
- 0.3m Close Focusing Capability: Achieves sharp, blur-free performance as close as 30cm from the target, perfect for desktop scanning or close-up near-field verification.

Applications & Compatibility
Core Application Scenarios
This 3MP 12mm M12 fixed focal lens is specifically designed for space-constrained environments that demand localized tracking and clear mid-range target isolation. It excels in CCTV security monitoring systems, such as narrow warehouse aisles, property hallways, community gate access points, and parking lot cash registers where panoramic wide angles would capture unnecessary background data waste. With its 0.3m minimum object distance, it provides reliable performance in commercial IoT smart devices, retail kiosk payment cameras, and facial-recognition turnstiles. Furthermore, it easily integrates into 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 Modules: Directly fits 1080P/3MP compact board-level IP camera modules from Hikvision, Dahua, Uniview, and Tuya-enabled smart home devices.
- Industrial Cameras: Mounts onto standard M12 board-level cameras used in light manufacturing, barcode reading, and code checking.
- Embedded Development Platforms: 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 focus on specific targets like cash registers, entry gates, or distant doorways without buying expensive varifocal lenses.
- Q: Will this lens experience vignetting or dark corners on my camera 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 changing 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: Can this lens handle heavy vibrations on moving machinery or robotic platforms?
- A: Absolutely. This is a fixed focal lens with a fixed iris, meaning there are no internal motorized moving parts. Once threaded into your camera board and locked, it is highly resistant to vibration drift.
- 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.
- Q: Does this M12 lens have a built-in day/night filter?
- A: This model features a transparent optical barrel to maximize light entry. If your application requires an integrated 650nm IR Cut Filter for daytime color accuracy, please state your requirement during ordering so we can customize it for you.
