Ikegami IK-H3Z4512CSIR 4.5-12.5mm F1.2 Day/Night Varifocal Lens

The IK-H3Z4512CSIR is a 1/2-inch format CS-mount lens with a 3x varifocal range from 4.5mm to 12.5mm, giving an installer room to dial in the exact framing on site. A fast F1.2 aperture pulls in light for cleaner images in dim scenes, and the day/night IR-corrected design keeps focus consistent as a true day/night camera moves between visible and infrared light.

Iris is set manually, which suits fixed-scene installs where lighting is controlled. The CS-mount threads onto 1/2-inch box and cube cameras, and pairs naturally with Ikegami bodies such as the ICD-49 and ICD-879S.
