Description
1/2.7″ 3.1mm 2MP M12 Ultra-Wide Angle Fixed Focal Lens
Enhance your compact imaging systems with this high-performance 1/2.7″ 2MP 3.1mm M12 wide-angle lens. Perfectly optimized for mainstream 1080P image sensors like the OV2710, this lens delivers a sweeping 145° diagonal field of view in full 2-megapixel clarity. Featuring an ultra-compact 14.00mm Total Track Length (T.T.L.) and a cost-effective 3G1P+IR filter (3 Glass + 1 Plastic + Infrared Filter) hybrid optical structure, it strikes an ideal balance between lightweight design and crisp image reproduction. With a bright F3.0 aperture and TV distortion controlled under 23%, it is a premier choice for value-driven wide-area surveillance and automotive vision.
Key Product Highlights
- 145° Sweeping Wide View: Captures an expansive panoramic perspective (120°H / 70°V) on 1/2.7″ sensors to significantly eliminate blind spots in various indoor and outdoor setups.
- Full HD 2MP Resolution: Engineered to deliver sharp edge-to-edge contrast and fine details, making it perfectly suited for standard 1080P high-definition monitoring.
- Ultra-Short 14mm Profile: With a Total Track Length (T.T.L.) of just 14.00mm, this low-profile lens seamlessly fits into space-constrained housings and ultra-thin smart devices.
- Low Geometric Distortion (<23%): Advanced optical alignment keeps TV distortion under 23%, mapping ultra-wide vistas with a more natural, linear composition compared to fish-eye lenses.
- Smart Hybrid 3G1P Optics: Combines 3 premium glass elements and 1 precision aspheric plastic layer to deliver optimized clarity and color control at a competitive cost.

Applications & Device Compatibility
Core Application Scenarios
This 2MP M12 wide angle lens is intentionally engineered for mass-market hardware deployments requiring wide-angle coverage and extremely compact dimensional boundaries. It serves as an ideal optical module for automotive dashcams, standard fleet-tracking cabin monitors, and rear-view backup displays where space behind the vehicle trim is tightly limited. In smart home ecosystems, it excels within smart residential video doorbells, affordable low-profile indoor IP dome cameras, and baby monitor units, allowing parents and tenants to capture complete room widths effortlessly. Its incredibly short 14mm T.T.L. profile also makes it highly efficient for budget-friendly FPV drone framing and robot navigation components.

Frequently Asked Questions
- Q: What is the benefit of the 3G1P + IR filter optical structure?
- A: The 3G1P structure utilizes 3 glass elements to provide optimal light transmission and structural durability, combined with 1 plastic element to reduce weight and overall manufacturing costs, providing high performance at an economical price point.
- Q: Why is the 14.00mm T.T.L. value important?
- A: Total Track Length (T.T.L.) is the distance from the front element of the lens to the image sensor. A short 14mm T.T.L. means this lens is incredibly compact, allowing your hardware engineers to design ultra-thin camera bodies, discreet doorbells, or low-profile vehicle mounts.
- Q: Can this lens be utilized on smaller sensor sizes?
- A: Yes, it can be mounted on 1/3″ or 1/4″ sensors. While it is fully compatible, please note that the field of view will crop proportionally, yielding a slightly narrower viewing angle than 145°.
- Q: Does this lens include a filter for daytime color precision?
- A: Yes, it contains a built-in fixed IR filter to block unwanted infrared light during daylight, ensuring accurate color processing, vibrant video feeds, and zero pink tinting.
- Q: How do you adjust the focus on this fixed focal M12 lens?
- A: Focus is set manually during your camera module’s assembly phase. The operator screws the lens into the M12 thread block while analyzing a live screen output. Once crisp focus at your target distance is established, it is locked using a locking ring or a drop of optical adhesive.
