BOSHI Optical Technology designs and manufactures this high performance wide angle lens tailored for 1/2.7 sensor based imaging devices. As a 3.26mm fixed focal lens with a remarkable F1.0 large aperture, it excels at capturing clear and bright images even in dim ambient light, which greatly reduces motion blur and improves low light imaging quality for security and monitoring use. This M12 mount CCTV lens delivers a 129.5 degree diagonal field of view, enabling broad scene coverage with fewer blind spots for wide area surveillance. It comes with a built in 650nm IR cut filter to deliver accurate color rendering in visible light environments, ensuring true to life image output for daytime monitoring.With a compact total length of 22.5mm, the lens fits easily into various compact camera housings and supports flexible installation in space constrained scenarios. It maintains stable optical performance across an operating temperature range from -20℃ to 70℃, adapting to both indoor and harsh outdoor environments. BOSHI Optical Technology applies strict quality control over every production link to ensure consistent performance and long service life. This F1.0 large aperture lens is a cost effective solution for modern CCTV systems, indoor monitoring, and general industrial imaging projects that demand wide coverage and reliable low light performance.

This high-performance M12 fisheye lens is engineered by ShangHai SILK Optical Technology CO., LTD to deliver seamless panoramic monitoring with an ultra wide angle field of view. Designed for 1/2.7” image sensors, this ultra wide angle lens adopts a mature 2G3P+IR optical structure, balancing compact size and all-day imaging capacity. It features a 2.18mm effective focal length, F2.4 fixed aperture and 185° diagonal field of view, enabling single-camera wide-area coverage without stitching multiple cameras.
