Hikvision DS-2SK8C440MXG1-LWF/28(25x25x) PTZ Network Camera
Review the manufacturer-documented specifications of the Hikvision DS-2SK8C440MXG1-LWF/28(25x25x) PTZ network camera. Compare resolution, zoom and movement features with their channel and configuration conditions.
Product description
The documented zoom specifications are: [PTZ channel 2/3]25 × optical, 16 × digital, [PTZ channel 1] 40 × optical, 16 × digital. Distinguish optical and digital zoom when planning scene coverage, and do not combine separate channel options into a single value.
The documented pan movement range is: [Base] 0° to 280° ,（Max.5000cycles）,[PTZ channel 2/3]0° to 360°, [PTZ channel 1] 0° to 360°. The tilt movement range is: [PTZ channel 2/3]-33° to 90°, [PTZ channel 1] -20° to 90°. Assess these mechanical limits alongside physical obstructions and mounting conditions when positioning the camera.
The manufacturer lists this supplementary illumination range: [PTZ channel 2/3]IR up to 150 m [PTZ channel 1] white light: up to 80 m; IR up to 350 m. Read values for different channels or illumination types separately, and check on-site lighting and visibility before installation.
