Note: The DS-2CD2126G2-I4 is the 4mm lens version of the DS-2CD2126G2-I. It combines AcuSense human/vehicle classification with DarkFighter low-light imaging, 120dB True WDR, and 30m IR illumination.
Important: The standard -I model does not include the built-in microphone and audio/alarm interfaces found on the -ISU variant. The exact lens version should be checked when ordering.
