Product Application Scenarios and Compatible Devices
Core Application Scenarios
This M12 wide-angle IR corrected lens is specially tailored for civilian and commercial surveillance, small-scale industrial vision collection, and smart home IoT monitoring applications. It excels in narrow installation spaces that require broad horizontal coverage, including indoor regional monitoring, small industrial equipment visual detection, low-power smart monitoring terminals, and short-distance peripheral environment capture. The 0.3m minimum object distance supports close-range shooting needs, while IR correction adapts to dim indoor, night and weak light working environments, solving blurry night imaging pain points of ordinary lenses. Its compact round body structure is easy to embed in mini electronic devices without extra space transformation.
Compatible Devices List
Fully compatible with 1/1.8-inch mainstream CMOS image sensors, and adaptive to partial 1/2.7-inch and 1/2.8-inch sensor modules for flexible device matching. It fits various mini CCTV cameras, smart home monitoring cameras, industrial miniature vision collectors, low-power IoT monitoring equipment, and small embedded video acquisition modules. The standard M12×0.5 thread mount enables direct replacement and installation of original factory lens accessories, and supports parameter adaptation adjustment for small-batch customized smart terminal equipment to meet personalized visual hardware demands.
Designed for surveillance and smart IoT vision application.
