Hikvision DS-A82024D Specsheet

Introduction

The DS-A82 series CVR is a duel controller network storage
for large-scale project with high demands on data safety.
The redundant modular design improves the system
reliability. It supports JBOD extension to expand the
storage space with mini-SAS interface, providing large
storage capacity for recordings.
