Hitachi VK-S274R/ER

Quick Overview

Analog SD Block Camera Module

The VK-S274R (NTSC ) / VK-S274ER (PAL) are RoHS-Compliant compact chassis-type cameras designed for surveillance under very low light conditions. Thanks to the optimized On-Chip Micro Lenses, sensitivity is dramatically improved and the smear level greatly reduced, meaning objects are captured effectively even under poor lighting. The Privacy Zone Masking and Mirror Image functions improve the versatility of the Hitachi video cameras. These models are RoHS-Compliant to enhance environmental friendliness.
