Description
Achieve flawless 24/7 surveillance with our professional 2.8mm M12 IR Corrected Lens. Engineered for 1/3″ Megapixel image sensors, this fixed focal board lens provides a crisp 121° diagonal field of view and a bright F2.0 aperture for superior low-light performance. Featuring advanced IR-corrected optics, it eliminates focus shift between day and night, making it the ultimate choice for CCTV security cameras, automotive dash cams, and smart home IoT devices that require seamless infrared night vision.
Product Highlights
- Day & Night IR Correction: Specially coated lenses eliminate chromatic aberration in the infrared spectrum, ensuring sharp, blur-free images when switching to IR night vision mode.
- 121° Megapixel Wide Vision: Delivers high-definition clarity across a wide 121°(D) / 90°(H) field of view, capturing expansive areas while maintaining minimal distortion compared to fisheye lenses.
- Bright F2.0 Aperture: Captures more ambient light to maximize sensor performance in low-light environments, reducing image noise and improving night-time identification.
- Rugged 4G All-Glass Build: Constructed with 4 precision glass elements (4G) to offer exceptional thermal stability, preventing focus degradation caused by extreme temperature variations.

Applications & Compatible Devices
Core Application Scenarios
This highly reliable IR corrected M12 lens is designed for multi-environment monitoring where lighting conditions shift dramatically. It is heavily utilized in residential smart video doorbells and IP security domes, allowing seamless clear capture from bright daylight to pitch-black environments utilizing 850nm or 940nm IR illuminators. The sturdy 4G glass architecture prevents focus drifting, making it ideal for automotive dash cams, commercial fleet cabin cameras, and outdoor smart parking systems. In automated industries, its megapixel resolution and wide view make it a trusted optical component for machine vision QR code scanners, access control facial recognition terminals, and warehouse AGV navigation cameras.
Compatible Device List
- Sensors: Fully optimized for 1/3″ and 1/4″ megapixel CMOS sensor modules (e.g., Sony IMX series, OmniVision, Onsemi).
- Security Hardware: Direct drop-in fit for mainstream Hikvision, Dahua, and Tuya smart IoT camera modules without modifying internal mounts.
- Development Platforms: Seamlessly integrates with Raspberry Pi High Quality camera boards, Jetson Nano modules, and standard megapixel USB industrial camera frames.
- Customization Available: Can be customized with integrated bandpass filters, specific anti-reflective (AR) coatings, or customized mechanical barrels to meet unique enclosure constraints.
Designed for day/night security and automotive video recording applications.
Frequently Asked Questions
Q: What is the main benefit of an IR Corrected lens compared to a standard lens?
A: Visible light and infrared light have different wavelengths, which usually causes them to focus at different points (focus shift). An IR Corrected lens uses specialized optical glass to ensure both light spectrums focus on the exact same plane, giving you sharp images both day and night without blur.

Q: Can this megapixel lens handle 1080P or 2MP resolution sensors?
A: Yes. This lens features megapixel-rated optical clarity, making it perfectly suited for 720P, 1080P, and standard 2MP sensors within the 1/3″ format size.

Q: Does this 4G lens configuration come with a built-in IR-cut filter switcher?
A: This is a standalone lens component with standard IR-corrected coatings. It does not include a mechanical switcher. For true day/night color rendering, it should be paired with an external camera-board-mounted IR-cut switcher.
