Applications & Compatible Devices
This premium M12 Wide Angle Lens is purpose-built for environments requiring an expansive field of view within a minimal physical footprint. It excels in residential and commercial security ecosystems, such as front-door smart video doorbells, property gate monitors, and compact dash cams, where capturing edge-to-edge action is critical. Additionally, its rugged 5G glass structure and minimal 0.3m object distance make it highly effective for indoor industrial automation, warehouse AGV guidance, and short-range machine vision inspection where environmental temperatures fluctuate.
- Compatible Device List: Fully compatible with standard 1/2.7″, 1/2.8″, and 1/3″ CMOS sensor modules. It seamlessly fits mainstream IP camera boards, Tuya/Smart Life IoT modules, Hikvision/Dahua low-profile surveillance housings, and DIY Raspberry Pi/Arduino wide-angle camera setups. Custom modifications for focal length, IR filtering, and thread length are available upon request.
Designed for wide-angle surveillance and smart IoT imaging applications.
Frequently Asked Questions
Q: What type of mount does this lens use, and will it fit my standard IP camera?
A: This lens features a standard M12x0.5 thread (S-Mount), which is the most common mount type for mini CCTV cameras, action cams, and IoT imaging boards.
Q: Can this 3MP lens be used with a 2MP (1080P) or 5MP sensor?
A: Yes. It is fully backward compatible with 2MP/1080P sensors, offering excellent clarity. For 5MP sensors, it will function perfectly but will resolve images up to its native 3MP optical performance.
Q: Does this wide-angle lens include an integrated IR cut filter?
A: Yes, the lens features a 5G+IRCF structure, meaning it includes a built-in Infrared Cut Filter to block stray infrared light during the day for accurate color reproduction.
Q: What is the benefit of the 5G (5 Glass) structure over plastic lenses?
A: All-glass elements provide significantly higher thermal stability, prevent aging or warping under direct sunlight, and offer superior light transmission compared to cheap plastic alternatives.
Q: Is the iris adjustable on this 2.8mm M12 lens?
A: No, this lens has a Fixed Iris at F2.0 to ensure maximum structural stability, lower maintenance, and optimal light intake for 24/7 security applications.
Q: What does “<50% distortion” mean for a 130-degree wide-angle lens?
A: For an ultra-wide Fisheye or Wide Angle Lens, geometric distortion is natural. A rating of <50% means the optical barrel distortion is heavily controlled to keep the image recognizable and flat at the edges while preserving a massive 130° view.
