    Records 512 camera channels redundantly across dual controllers.
    This 48-bay embedded video storage unit writes 512 IP camera channels straight to disk on standard dual controllers and reaches 1024 Mbps of incoming bandwidth. SAS cascading grows the storage space, which suits large-scale monitoring centers that cannot tolerate downtime.
