Application Scenarios & Compatible Devices
Core Application Scenarios
This ultra-wide-angle M12 lens is purpose-built for applications demanding maximum spatial coverage within restricted installation footprints. It excels in automotive dashcams and backup cameras, providing drivers with comprehensive rearview situational awareness. In smart home ecosystems, it serves as the optical core for smart video doorbells and panoramic home security cameras, capturing full-porch or full-room views. Additionally, its lightweight 20.7mm T.T.L. profile makes it ideal for Drone & UAV navigation systems, low-altitude aerial mapping, and machine vision sorting lines where close-range (\(0.3\text{m}\) M.O.D.) wide-field monitoring is critical.
Compatible Device Registry
- Sensor Compatibility: Optimized for 1/2.5″ CMOS sensors; backward compatible with 1/2.7″, 1/2.8″, and 1/3″ mainstream image sensors (e.g., Sony IMX series, OmniVision).
- Security Hardware: Seamlessly integrates with Hikvision, Dahua, and Tuya IoT smart camera modules and video doorbells.
- Industrial & Robotic Systems: Compatible with compact machine vision cameras, Raspberry Pi / Arduino camera modules, and automated guided vehicle (AGV) tracking units.

“Designed for panoramic security surveillance and compact machine vision applications.”
Frequently Asked Questions
Q: Does this 2.8mm lens experience focus shift when switching to infrared night vision?
A: No. This lens is fully IR corrected, meaning its optical coatings and glass elements align both visible and infrared light onto the same focal plane, preventing any night-vision blurring.
Q: Can this lens be used on a smaller sensor format, like a 1/3″ sensor?
A: Yes, it is fully compatible with smaller sensor sizes like 1/2.7″ and 1/3″. Please note that using a smaller sensor will slightly crop the image, resulting in a narrower field of view than the rated 170°.
Q: What does the “<85%” distortion rating mean for a fisheye lens?
A: For an ultra-wide 170° fisheye lens, optical distortion is inevitable to achieve such a wide field of view. The <85% rating means the barrel distortion is optically controlled and optimized, making it easy to rectify via backend software algorithms if needed.
Q: Is the iris adjustable for changing light conditions?
A: No, this lens features a Fixed Iris with a constant aperture of F2.6. It balances optimal light intake and depth of field, relying on the camera sensor’s electronic shutter to manage exposure changes.
Q: Does this lens require an external mounting bracket for installation?
A: It uses a standard S-mount (M12x0.5 thread). It screws directly into any standard M12 lens holder or camera board module without needing external brackets or modifications.
