Applications & Compatible Devices
Core Application Scenes
This 4MP M12 CCTV lens is engineered for space-constrained, wide-view environments. It excels in compact security setups like smart video doorbells and building intercoms, providing full-porch coverage. In industrial automation, its low C.R.A. (<11°) and high R.I. make it highly effective for robotic arm visual sorting, PCB inspection, and automated assembly line scanning. Additionally, it serves as a reliable lens for in-cabin automotive monitoring or dashcams, capturing complete interior cabin views without blind spots under varying temperature fluctuations.

Frequently Asked Questions
- Q: What is the main benefit of the 6G construction in this M12 lens?
- A: The 6G (6-layer all-glass) optics provide superior light transmission and thermal stability compared to plastic lenses, preventing focus shift or image degradation in outdoor or high-temperature industrial environments.
- Q: Can this 1/3″ format lens be used on a 1/2.8″ sensor?
- A: We do not recommend using it on a 1/2.8″ sensor, as it may cause vignetting (dark corners). It is optimized for 1/3″ or smaller sensor formats.
- Q: What does -24% distortion mean for my image?
- A: A -24% distortion represents a barrel distortion typical for wide-angle lenses. It can be easily corrected via software back-end algorithms if perfectly straight lines are required for machine vision.
- Q: Is this lens suitable for day and night surveillance?
- A: Yes. Its large F1.8 aperture allows ample light for low-light night conditions. (Note: Depending on your sensor setup, an external IR-cut switcher may be required for full night vision).
- Q: Do you support OEM or custom modifications for this product?
- A: Yes, we provide custom services for adjusting the AR coating, IR-filter integration, or altering the F.O.V. to fit your exact project requirements.
