Pelco SL183A-MSI 5 Megapixel CS-Mount Varifocal Lens 1.8–3mm, F1.8, 1/2.7"

The Pelco SL183A-MSI is a 5-megapixel rated CS-mount varifocal lens with an ultra-wide 1.8-3mm focal range and F1.8 maximum aperture — optimized for 1/2.7-inch format sensors, providing broad wide-angle coverage at the shortest end of the zoom range for indoor fixed cameras in tight spaces where the widest possible FOV is required.

Features

• 5MP rated CS-mount varifocal lens; focal range: 1.8-3mm; maximum aperture: F1.8; image circle: 1/2.7-inch format; manual zoom and iris
• 1.8-3mm ultra-wide varifocal: starts at 1.8mm — an extremely wide angle providing close to 180° diagonal FOV in a compact room or corridor — and zooms to 3mm for a slightly tighter view; correct for cameras that must cover very wide areas from close ceiling mounting heights
• F1.8 fast aperture: maximizes light collection for the widest possible low-light performance without IR illumination — particularly important at ultra-wide angles where supplemental IR often creates uneven illumination across the very broad field of view
