- Security Hardware: Direct fit for Hikvision, Dahua, and Tuya-based IoT smart doorbells or mini dome camera enclosures without bracket modifications.
- Industrial & Dev Boards: Seamlessly integrates with Raspberry Pi camera modules, Jetson Nano platforms, and custom USB industrial camera boards.
- Customization: Supports tailored adjustments for specific IR filter wavelengths or specialized FOV requirements to match your unique hardware architecture.
Designed for panoramic security and automotive monitoring applications.
Frequently Asked Questions
Q: Will this 2.2mm lens work with a 1/2.8″ sensor?
A: This lens is optimized for a 1/3″ image format. If used on a larger 1/2.8″ sensor, you may experience slight black corners or vignetting around the edges of the image.
Q: What does the “-87% Optical Distortion” mean for my image?
A: This indicates a traditional fisheye barrel distortion effect. It allows the lens to capture an ultra-wide 170° view. For straight-line accuracy, this distortion can be easily corrected using software de-warping algorithms.
Q: Does this M12 lens include an integrated IR cut filter?
A: Yes, the lens features a built-in 5G+IR cut filter config. It blocks infrared light during daytime to prevent color shifting and works perfectly with daylight or controlled studio lighting.
Q: Is the focus adjustable, or is it permanently locked?
A: The lens features manual focus adjustment via the M12 thread during installation. Once you achieve the optimal focus for your target distance, it can be locked securely in place using an M12 lock ring or glue.
Q: Can this lens withstand extreme outdoor temperatures in automotive use?
A: Absolutely. Thanks to its 5G (all-glass) component design, this lens prevents the thermal defocusing common in plastic lenses, ensuring stable image quality in hot dashboards or freezing outdoor environments.
