2.1mm 4MP M12 IR Corrected Ultra Wide Angle Lens
This 2.1mm M12 IR corrected lens is designed for compact camera modules that require an ultra-wide field of view and stable imaging across changing lighting conditions. With a 155° diagonal FOV, 4MP resolution, F1.4 aperture, and M12 × 0.5 mount, this fixed focal lens combines wide-area coverage with strong light-gathering capability for smart security, IoT, embedded vision, and other compact imaging systems.
2.1mm M12 IR Corrected Lens Core Highlights
- 155° Ultra-Wide FOV for Maximum Scene Coverage — The 2.1mm focal length provides a 155° diagonal and 125° horizontal field of view, helping compact cameras capture a much larger area from short installation distances and reduce blind spots.
- F1.4 Large Aperture for Low-Light Imaging — The F1.4 aperture offers excellent light‑gathering performance for indoor monitoring and variable‑light applications.
- 4MP Resolution for Detailed Wide-Area Imaging — The 4MP optical configuration provides more image detail than standard 2MP designs, helping camera systems retain useful visual information across a broad field of view.
- IR Corrected for Consistent Imaging Across Wavelengths — The IR corrected optical design helps maintain focus consistency when the camera operates with infrared illumination, making the lens suitable for imaging systems that switch between visible and near-infrared lighting.
- M12 × 0.5 Mount for Compact Camera Integration — The standard M12 interface supports integration with compact camera modules and embedded imaging equipment where optical size and mechanical compatibility are important design considerations.
2.1mm M12 IR Corrected Lens Applications
This 2.1mm M12 IR corrected lens is particularly suited to compact cameras that need very wide scene coverage together with reliable imaging under both visible and infrared illumination. Its 155° diagonal FOV, F1.4 aperture, 4MP resolution and IR‑correction suit low‑light and variable‑lighting applications.
- Smart Video Doorbells — Its 125° horizontal FOV covers entrance‑area visitors, and IR correction enables nighttime infrared operation.
- Indoor Smart Security Cameras — The ultra-wide field of view allows a compact camera to monitor rooms, entrances, corridors, and other close-range areas. The F1.4 aperture is beneficial when indoor lighting is limited.
- Night Vision IoT Cameras — IR correction helps maintain optical focus when infrared LEDs are activated, making the lens suitable for smart cameras designed for day-and-night monitoring.
- Compact IP Camera Modules — The M12 × 0.5 mount provides a compact mechanical interface for embedded camera modules requiring a wide field of view without using a larger C-Mount or CS-Mount optical assembly.
- Embedded Vision Devices — This ultra‑wide, 4MP compact‑mount lens works for size‑sensitive connected and embedded vision products.
Compatible equipment: This lens is designed for compatible 1/3″ CMOS camera modules with an M12 × 0.5 interface, including smart doorbell cameras, compact IP camera modules, indoor security cameras, IR night-vision cameras, IoT vision devices, and embedded monitoring equipment.
